- h(x) = f(x) + g(x) =
- h(x) = g(x) – f(x) =
- h(x) = 4g(x) =
<u>Step-by-step explanation:</u>
Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or 
.

Answer:
<u>18°</u>
Step-by-step explanation:
sin 2x=cos zy
m(2x)=72°
cos(π/2-a)=sin a
cos(π/2-72°)=sin72°
cos18°=sin72°
=>m(zy)=18°
x=9 because the triangle is equilateral which means every side is equal to 60. When you do the math you get 7x-3=60 which is 7x=63 and 63/7=9
Step-by-step explanation:
So if you are reflecting across the x-axis then the point after the reflection should be (x,-y). If you are reflecting across the y-axis the the point after the reflection should be (-x,y). If you are reflecting across the line y=x, then the point after the reflection should be (y,x) If you are reflecting across the line y=-x, then the point after the reflection should be (-y, -x). If you are reflecting across the origin, then the point after the reflection should be(-x,-y). Hope this helps.
