Answer:
f(-5) = 19
Step-by-step explanation:
f(t) = -3t+4
Let f(t) = 19
19 = -3t+4
Subtract 4 from each side
19 - 4 =-3t+4-4
15 = -3t
Divide each side by -3
15/-3 = -3t/-3
-5 = t
19 i think though im pretty sure it is
2x + y = 17
To solve for y, subtract 2x from both sides;
y = 17 - 2xTo solve for x, subtract y from both sides;
2x = 17 - y
Divide both sides by 2;

Answer:
24x+54
Step-by-step explanation:
8(3x+5)= 24x+40
24x+40+14=24x+54
24x+54
The answer is b, fine the initial speed of the ball
