Answer:
B. 10
Step-by-step explanation:
36 + 3x = 66
3x= 66-36
3x = 30
x = 10
Reflecting over the x axis means to perform the following tranformation:

So, you maintain the x coordinate, and change the sign of the y coordinate. The vertices become

Translating 3 units to the left means to perform the following transformation:

So, you maintain the y coordinate, and decrease the x coordinate by 3. The vertices become

So, as you can see, after these two transformation, the vertices A, B and C become A', B' and C'.
hello there
the answer is 26x
Let's simplify step-by-step.
5x−2x+6x−x+3x+15x
=5x+−2x+6x+−x+3x+15x
Combine Like Terms:
=5x+−2x+6x+−x+3x+15x
=(5x+−2x+6x+−x+3x+15x)
=26x
hope this helps
Answer:
y - 8 = -2(x - 9)
Step-by-step explanation:
Given the slope, m = -2, and the point, (9, 8):
Let (x₁, y₁) = (9, 8)
slope (<em>m </em>) = -2
We can substitute these values into the following <u>point-slope form</u>:
y - y₁ = m(x - x₁)
y - 8 = -2(x - 9) ⇒ This is the point-slope form.
