Add 7 to both sides
Y+7=3
Divide both sides by 3
Y+7/3=x
Switch sides
X=y+7/3

The two horizontal lines are parallel ( This is given by the red triangles)


Because the lines are parallel, the two angles 1 & 2 would be the same.

Set the two equations for the angle to equal each other and solve:

8y-6 = 7y

Add 6 to each side:

8y = 7y+6

Subtract 7y from each side:

y = 6

Now you have the value for y, solve for angle 2 by replacing y with 6:

Angle 2 = 7y = 7(6) = 42 degrees.

If you apply the changes below to the absolute value parent function, f(x) = |x|, what is the equation of the new function?Shift
Serjik [45]

Answer: C

<u>Step-by-step explanation:</u>

The general form of the equation is: g(x) = a|x - h| + k  ;

  • "a" represents the vertical stretch <em>(or shrink)</em>
  • "h" represents the x-coordinate of the vertex (left and right)
  • "k" represents the y-coordinate of the vertex (up and down)

4 units left means h = 4

2 units up means k = 2

--> g(x) = |x - 4| + 2
