Given that f(x)=x^2-x and g(x)=3x+9, Find
(A) (f+g)(-2)=
(B) (f-g)(-2)=
(C) (fg)(-2)=
(D) (f/g)(-2)=
The value of the following composite function is as follows:
(f + g)(-2) = 5(f - g)(-2) = - 5(fg)(-2) = 18(f/g)(-2) = 2How to solve composite function?The composite functions can be solved as follows:
Therefore, the given function are:
f(x) = x² - x
g(x) = 3x + 9
Hence,
a.
(f + g)(-2) = f(-2) + g(-2)
f(-2) + g(-2) = (2)² - 2 + 3(-2) + 9
f(-2) + g(-2) = 4 - 2 - 6 + 9
f(-2) + g(-2) = 5
Therefore, the function (f + g)(-2) = 5
b.
(f - g)(-2) = f(-2) - g(-2)
f(-2) - g(-2) = (2)² - 2 - (3(-2) + 9)
f(-2) - g(-2) = 4 - 2 - 3
f(-2) - g(-2) = -5
Therefore, the function (f - g)(-2) = - 5
c.
(fg)(-2)= f(-2) × g(-2)
f(-2) × g(-2) = (-2)² - (-2) × 3(-2) + 9
f(-2) × g(-2) = 4 + 2 × 3
f(-2) × g(-2) = 6 × 3
f(-2) × g(-2) = 18
Therefore, the function (fg)(-2) = 18
d.
(f/g)(-2) = f(-2) / g(-2)
f(-2) / g(-2) = -2² - -2 / 3(-2) + 9
f(-2) / g(-2) = 6 / 3
f(-2) / g(-2) = 2
Therefore, the function (f/g)(-2) = 2

Mrs. Escalate was riding a bicycle on a bike path. After riding 2/3 of a mile, she discovered that she still needed to travel 3/4 of a mile to reach the end of the path. How long is the bike path?
Answer:
17/12
1 5/12
Step-by-step explanation:
If we make the fractions have common denominators, this problem is a piece of cake.
First, since the closest multiple of 3 and 4 is 12, put 12 instead of the 3 and 4.
Since 3x4=12, multiply 2x4.
2x4=8.
So the first fraction would be 8/12
Next, since the 4 turned into a 12, multiply 3 by 3.
3x3=9
So the second fraction would be 9/12.
Now, add 9/12 and 8/12 together.
9/12+8/12=
17/12
1 5/12

Which number can you add to 14 to get a sum of 0?
Inverse operation
14 + (-14) =0
Answer:
The number is -14.
Step-by-step explanation:
Up to now, you've been working with whole numbers. These are the positive numbers, those numbers you usually count with your fingers (1, 2, 3, ...), and 0. You've been working with these numbers ever since elementary school, where you would do computation with them, like adding, subtracting, and multiplying them. And, on a number line, they go from left to right, starting at 0.
But what happens when you go to the left on the number line? That is, what's before 0? We actually find negative numbers. The normal numbers that we usually work with, that being the positive numbers, now look like this:
(-1, -2, -3, ...)
A good thing to come from this is that now, we can define an additive inverse. An additive inverse is the negative, or opposite, of a whole number. The sum of a number and its additive inverse is 0.
So, for example, the additive inverse of 1 is -1, and 1 + (-1) = 0.
So clearly, we can see that the additive inverse of 14 is -14, since
14 + (-14) = 0.
(In case you wanted to know, the additive inverse of 0 is 0 because 0 is neither negative nor positive. So, 0 + 0 = 0.)

How many cups of milk per tablespoon of cocoa is that?
cups
In one cup of milk there is 1.5 tablespoons of cocoa and one tablespoon of cocoa is mixed in 0.67 cups of milk.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the value of single unit according to the needs.
Given is Han who made some hot chocolate by mixing 4 cups of milk with 6 tablespoons of cocoa.
There are 6 tablespoons of cocoa in 4 cups of milk.

How can the system of equations be solved using Cramer's rule?
Drag a value or determinant expression into each box to correctly solve the system using Cramer's rule.
The solutions are x = -1 and y = 3 of the given system of equations 2x+y=1, −3x+4y=15 which is determined by Cramer's rule.
We put the tiles in the right order and entered the final result for each x and y.
The main principle is to split determinants as shown by the vertical bars (these are not absolute value bars).
The determinant of the matrix [tex]\begin{bmatrix}2 & 1 \\-3 & 4 \\\end{bmatrix}[/tex], which are the coefficients of the left-hand side of each original equation supplied to you, is in each denominator.
This matrix's numerators are somewhat different. The x determinant requires you to replace the first column with 1 and 15 to produce [tex]\begin{bmatrix}1 & 1 \\15 & 4 \\\end{bmatrix}[/tex], which aids in determining the x solution. The y solution is similar, except we replace the y column rather than the x column. This explains the [tex]\begin{bmatrix}2 & 1 \\-3 & 15 \\\end{bmatrix}[/tex].
You just evaluate each determinant using the formula once you have the right determinants in place and then simplify the outcomes.
Thus, the solutions are x = -1 and y = 3 of the given system of equations 2x+y=1, −3x+4y=15 which is determined by Cramer's rule.

Lincoln high wants to estimate the number of students who drive to school. Answer the following
GIVEN:
We are told that a school wants to estimate the number of students who drive to school.
Required:
To determine which survey would best represent the entire student population..
Step-by-sep solution;
Taking a sample of 11th graders would not correctly represent the entire student population. The result from this survey would at best represent the preference of 11th grade students and not other grades. The same thing applies to a survey of the science club. The science club cannot accurately represent all students (including other clubs).
However, a survey of 25 students from the school would best represent the entire student population since there is a probability of every category of student being represented.
Therefore,
25 students are randomly selected from the school; 4 drive to school.
Part (B):
There are 1750 students at Lincoln High. Use the answer above to estimate the number of students who drive to school.
If the sample of 25 students has 4 students who drive to school, then to estimate the entire population based on this;
[tex]\begin{gathered} Sample\text{ }proportion=\frac{4}{25} \\ \\ Population\text{ }proportion=\frac{4}{25}\times1750 \\ \\ Population\text{ }proportion=280 \end{gathered}[/tex]Therefore, we now have;

Equation of the line that passes through the points in the table:
x=0,1,2,3
y=10,7,4,1
is y = -3x + 10
What is Equation of the Line?
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Key Concept. Y = mx + c is the equation for a straight line with a gradient of m and an intercept of c on the y-axis.
Since, The Equation of the line:
y = mx + b
where m is the slope
For finding slope passing through (0,10) and (1, 7)
m = (y2 - y1)/(x2 - x1)
m = (7 - 10) / (1 - 0)
m = -3/1
m = -3
Therefore, the slope of the line is −3.
Now use the slope and either of the two points to find the y-intercept.
y=mx+b
10 = (-3)(0) + b
10 = b
Write the equation in slope intercept form as:
y=mx+b
y = -3x + 10
Hence, the equation of the line is y = -3x + 10
Now, for other two points (2, 4) and (3, 1)
For finding slope passing through (2, 4) and (3, 1)
m = (y2 - y1)/(x2 - x1)
m = (1 - 4) / (3 - 2)
m = -3/1
m = -3
Therefore, the slope of the line is −3.
Now use the slope and either of the two points to find the y-intercept.
y=mx+b
4 = (-3)(2) + b
4 = -6 + b
4+6 = b
b = 10
Write the equation in slope intercept form as:
y=mx+b
y = -3x + 10
Hence, the equation of the line is y = -3x + 10

Greg the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the other (not both). On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. On Thursday there were 2 clients who did Plan A and 12 who did Plan B. Greg trained his Wednesday clients for a total of 9 hours and his Thursday clients for a total of 9 hours. How long does each of the workout plans last?
The workout plan A lasts 1 hour and 30 mins and the workout plans B last around 30 mins only, solved through elimination method.
What is elimination method?The equations are either added or subtracted to create an equation in one variable when using the elimination method. When two variables' coefficients are in opposition to one another, you add the equations to eliminate that variable, and when they are equal, you subtract the equations to do the same.
Let the time taken for plan A be x
and the time taken for plan B be y
Then the equation forms
Wednesday = 5x + 3y = 9 hours
Thursday = 2x + 12y = 9 hours
Lets solve this with elimination method
5(2x + 12y = 9 hours)
-2(5x + 3y = 9 hours)
⇒ 10x + 60y = 45 hours
-(10x + 6y = 18 hours)
0 + 54y = 27 hours
⇒ y = 27/54 hours
y = 1/2 hours
y = 30 mins
Substituting the value of y in 2x + 12y = 9 hours,
2x + 12(0.5)= 9 hours
2x + 6 = 9 hours
2x = 3 hours
x = 3/2 hours
x = 1 hour 30 mins
Thus, the workout plan A lasts 1 hour and 30 mins and the workout plans B last around 30 mins only.

Julia received an 88, 90, 94, 89 on her first four English quizzes. What must she get on her fifth in order to have a 92 average?
Answer:
99
Step-by-step explanation:
You can set up a proportion, and solve for the variable (missing grade in this case):
[tex]\frac{88+90+94+89+x}{5} =92[/tex]
Each grade is already in the database, so it can serve as the constant, and five is the denominator because to get a mean average, you must divide all the values by the number of values that exist. So, in this case, it would be 5, 4 including the missing grade, making it 5. Set the equation equal to 92, because that's her desired average, then just solve for x.
Multiply the 5 on both sides.
-> 5 cancels on left, and 5 multiplies with 92 to get 460.
[tex](5)\frac{88+90+94+89+x}{5} = 92(5)[/tex]
Add all constants on the left side of the equation.
-> 88+90+94+89=361
[tex]361+x = 460[/tex]
Subtract that new constant (361) from the 460, and you get x=92.
-> 460-361=99
[tex]x=99[/tex]
