Answer:
-27
Step-by-step explanation:
Given expression:
-9(x + 3) = 27
Now use the open the bracket;
-9x - 27 = 27
Given -9x + (?) = 27
Comparing the two equations shows that the question mark corresponds to the value -27;
The solution is -27

One math student, John, can solve 6 math problems in 20 minutes while another student, Juaquine, can solve the same 6 math problems at a rate of 1 problem per 4 minutes. Who works faster?
1.John
2.Juaquine
Answer:
John
Step-by-step explanation:
6/20=0.3
1/4=0.25
Juaquine is solving problems at a faster rate as compared to John.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
As per the question, we can compare their rates of problem-solving by calculating the number of problems they can solve per minute.
For John, this is 6 problems / 20 minutes = 0.3 problems per minute.
For Juaquine, this is 6 problems / (4 minutes/problem) = 1.5 problems per minute.
Since Juaquine can solve 1.5 problems per minute compared to John's 0.3 problems per minute, Juaquine is solving problems at a faster rate.
Hence, Juaquine works faster as compared to John.

Step-by-step explanation:
Rewrite the equation 2y - 4x = 10 in function notation where f(x)= y.
f(x)=
Answer:
Answer:
f(x) = 5 + 2x
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.
Answer:
f(x) = 5 + 2x
Step-by-step explanation:
2y - 4x = 10
+4x +4x
2y = 10 + 4x
Now we have a new equation but we have to isolate the variable y.
[tex]\frac{2y}{2}[/tex] = [tex]\frac{10 + 4x}{2}[/tex] Then divide to solve for y.
y = 5 + 2x
Since f(x) is the same thing/equal to y we can just replace that.
f(x) = 5 + 2x

(1 point) The linear function y=3x+30 models the average cost of a haircut in a certain city, where y, is the average price of a haircut x years after 2000. Find the slope for the model. Then describe what this means in terms of the rate of change in the average cost of a haircut over time.
Answer:
3 is the slope
Step-by-step explanation:
Mathematically, a linear function can be represented in the form;
y = mx + c
where m represents the slope and c is the y-intercept of the function.
In the equation given in the question above;
The slope of the equation is 3
What this means is that, the average rate of change between two points in the plot of the linear function is 3
Mathematically speaking, we mean that given two years and their corresponding average haircut prices, then the average rate of change between these two years on the plot is 3

Dividing by 2 always produces a number less than the original number
Dividing the number by 2 gives half of the number which is less than the original number.
Given that,
To specify dividing by 2 always produces a number less than the original number.
A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Dividing the number by 2 gives half of the number which is less than the original number.
Let the number be x,
Dividing the number by 2
Gives, x / 2 = 0.5 * x
Imply,
Dividing the number by 2 gives half of the number which is less than the original number.
Thus, dividing the number by 2 gives half of the number which is less than the original number.

Answer:
88 degrees
Step-by-step explanation:
First, notice that when you rotate a point 272 degrees clockwise, there will be 88 more degrees before it returns to its original point (since a 360 turn is equivalent to not moving, and 360-272=88).
Because of that, we can deduce that rotating a point 88 degrees counterclockwise will be equivalent to rotating it 272 degrees clockwise.
We can know that that's the smallest possible positive answer, because any angle smaller than 360 will be the smallest possible way to express it.

Answer:
Step-by-step explanation:
f(x) = 2x^4(x + 2) + 11x^2(x + 2) + 12(x + 2)
f(x) = (x+2) [2x^4 + 11x^2 + 12]
f(x) = (x + 2)(2x^2 + 3)(x^2 + 4)
