Answer:
infinite solutions
Step-by-step explanation:
4x+4(3x+7) = 8(2x-3) +52
Distribute
4x+12x+28 = 16x-24+52
Combine like terms
16x+28 = 16x +28
Subtract 16x from each side
16x-16x+28 = 16x-16x +28
28=28
This is true, so there are infinite solutions
You should search it on youtube becouse pepople cant really explain or draw the shape to show you
2 is the answer Hope it helped
Answer:
c+d>15
Step-by-step explanation:
Usually there's more to the question.. the inequality doesn't look too right, but it could be.
First, we differentiate the equation for the distance so to find the velocity in feet per second (ft/s).
f(t) = -16t² + 48t + 100
Differentiating,
df(t)/dt = -32t + 48
The value at t = 3 is,
df(t) / dt = -32(3) + 48 = -48 ft/s
The value at t = 5 is
df(t) / dt = -32(5) + 48 = -112 ft/s
The average of both values is -80 ft/s.
