Answer:
Step-by-step explanation:
f(x) = -5x + 8(7 - x)......when f(x) = 160
160 = -5x + 8(7 - x)
160 = -5x + 56 - 8x
160 - 56 = -5x - 8x
104 = - 13x
-104/13 = x
-8 = x <====
Answer:
Cos(F) = 0.47059
Step-by-step explanation:
Cos(F) = adjacent / hypotenuse
adjacent = 8
hypotenuse = 17
Cos(F) = 8 / 17
Cos(F) = 0.47059
The answer would be ooo ahhhh eeee wala wala bang bang

24 x 28 = 672
Answer:
-24
Step-by-step explanation:
First find f(3), which is the value of the blue line when x =3
f(3) = -2
Then find g(-1) which is the value of the red line when x= -1
g(-1) = 6
-6 f(3) - 6*g(-1)
-6*-2 - 6(6)
12 - 36
-24
