Write an equation of the line passing through the point (6,-2) that is parallel to the line y=4x-11
Answer:
y=4x-26
Step-by-step explanation:
First, a parallel equation, ALWAYS has the same slope. Just plug in your x value into 4(x) , then find a number that adds or subtracts to get your y value, and that number you added or subtracted is your y-intercept.
The equation of the line passing through the point (6,-2) that is parallel to the line y=4x-11 is y = 4x - 26
The equation of the linear passes through the point (6, -2) and is parallel to the line y = 4x - 11
Parallel lines have the same slope.
Therefore,
y = 4x - 11
using
y = mx + b
where
m = slope
b= y-intercept
Therefore, the slope of y = 4x - 11 is 4.
And the slope of the other line will be 4 because they are parallel.
Therefore,
y = mx + b
y = 4x + b
it passes through (6, -2)
-2 = 6(4) + b
-2 - 24 = b
b = -26
The equation will be y = 4x - 26

Step-by-step explanation:
The value of a is 8.
Option A is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
XZ = XY + YZ
40 = 3a + 8 + a
40 = 4a + 8
40 - 8 = 4a
32 = 4a
a = 32/4
a = 8
Thus,
a is 8.

Which strategie would eliminate a variable in the system of equations? −x+6y=8 7x−y=−2
Answer:
substitution (or addition)
Step-by-step explanation:
A simple strategy for this system is to use substitution. The first equation is easily solved for x, so you could substitute that into the second equation:
x = 6y -8
7(6y -8) -y = -2 . . . . . x variable eliminated
__
The second equation is easily solved for y, so you could substitute that into the first equation.
y = 7x +2
-x +6(7x +2) = 8 . . . . . y-variable eliminated
__
The "addition" method is always a good way to eliminate a variable.
When the coefficient of a variable in one equation is a divisor of the coefficient of that variable in the other equation, a simple multiplication and addition will do.
To make the coefficient of x in the first equation the opposite of the coefficient of x in the second, multiply the first equation by 7. Adding that result to the second equation will eliminate x:
7(-x +6y) +(7x -y) = 7(8) +(-2)
42y -y = 56 -2 . . . . . . x-variable eliminated
Likewise, the second equation can be multiplied by 6 and added to the first to eliminate the y-variable:
(-x +6y) +6(7x -y) = (8) +6(-2)
-x +42x = -4 . . . . . . . . y-variable eliminated
__
It is often the case that using either substitution or "addition" requires about the same amount of work.
Here, the solutions are (x, y) = (-4/41, 54/41).
Solve for x.
-6x - 29 = 5x - 7
Answer:
x = -2
Step-by-step explanation:
-6x - 29 = 5x - 7
Add -6x to both sides
-29 = 11x - 7
Add 7 on both sides
-22 = 11x
Divide
[tex]\frac{-22}{11}[/tex] = [tex]\frac{11x}{11}[/tex]
x = -2
Answer:
x = -2
Step-by-step explanation:
move the terms
-6x -5x = -7 + 29collect like terms
-11x = 22
divide both sides of the equation by -11

the solution to 5/2 x-7 =3/4 x +14
Answer:
x = 12.
Step-by-step explanation:
5/2x - 7 = 3/4x + 14.
put the like terms together keeping in mind that when a number crosses the equal sign it changes its sign and it acquires the opposite sign.
5/2x - 3/4x = 14 + 7
7/4x = 21.
divide both sides by the reciprocal of 7/4, the number next to the unknown
so x = 21 ×4/7
x = 12.
Hey guys i was wondering if i could get some help
==================================================
Explanation:
The given piecewise function basically means we have h(x) defined in two different ways based on what x is
If x is less than 2, then h(x) = 4 - x^3 which is what the first row says
Or
If x = 2 or larger, then h(x) = 2x-3 which is what the second row says.
---------
We want to find h(0). We want to find h(x) when x = 0. We'll use the first definition since x = 0 is less than 2.
h(x) = 4 - x^3
h(0) = 4 - (0)^3
h(0) = 4 - 0
h(0) = 4

Formula: 0.5*[sum of parallel sides] *height
Answer:
636 in.²
Step-by-step explanation:
First divide the shape into three pieces, you will get a triangle and two rectangles, the base of the triangle is 30 in. The height is 8 in. Multiply 30×8 to get 240 and then divide by two to get 120. Next the rectangle on top has sides that are 24 in. and 8 in. You will get 192. Lastly the rectangle on the bottom has sides of 54 in. and 6 in. For this you will get 324. Finally you add up 120+192+324 to get 636 in.²
Given the graphs of y = f(x) and y = g(x),
g(x) = f(x)
expresses g(x) in terms of f(x).
Step-by-step explanation:
g(x) = f(x) + 4.
This is because g(x) is a translation of f(x) that has been moved up by 4 units. (-2 to 2 when x = 0)
Given the graphs of y = f(x) and y = g(x),
g(x) = f(x) + 3
expresses g(x) in terms of f(x).

Kami is cooking dinner for a family reunion that 21 people are attending. If her recipe calls for 1.6 ounces of ground beef per person, how much beef does Kami need altogether?
Answer:
Kami will need 33.6 ounces of ground beef for the recipe
Step-by-step explanation:
From the problem, we know that one person will use up 1.6 ounces of ground beef. We also know that there are 21 people that will be attending the party. Each of those 21 people will definitely use up 1.6 ounces of ground beef.
Hence, for the recipe to be perfect, Kami will have to use 21 X 1.6 ounces = 33.6 ounces of ground to make the recipe for the entire dinner.
3(x-1)-2(2x+1)=8(x-1)
Answer:
x = 1/3
Step-by-step explanation:
3(x-1)-2(2x+1)=8(x-1)
Distribute
3x -3 -4x-2 = 8x -8
Combine like terms
-x -5 = 8x -8
Add x to each side
-x-5+x = 8x-8+x
-5 = 9x-8
Add 8 to each side
-5+8 = 9x-8+8
3 = 9x
Divide by 9
3/9 = 9x/8
1/3 =x
3(x-1)-2(2x+1)=8(x-1)
Use distributive property:
3x-3 -4x-2 = 8x-8
Combine like terms:
-x -5 = 8x -8
Add 8 to both sides:
-x +3 = 8x
Add x to both sides:
3 = 9x
Divide both sides by 9:
x = 3/9
x = 1/3

how do you solve this
Answer:
4x^-4/9y^6
Step-by-step explanation:
If the exponent is outside the bracket, it means that all the terms inside will be raised to that exponent. This means that:
(2x^-2 / 3y^3)^2 = 2^2*(x^-2)^2 / 3^2*(y^3)^2
When exponents are raised to an exponent, the exponents are multiplied together, so (x^-2)^2 will = x^(-2*2) = x^-4
Going through:
2^2*(x^-2)^2 / 3^2*(y^3)^2
=4*x^-4 / 9*y^6
=4x^-4/9y^6
Hope this helped!
