1. What is the value of y in the equation 4 + y = –3? y = -3 – 4 y = -7
Answer:
1.25r+8=28
Step-by-step explanation:
When the direction is reversed velocity = 0
v = ds/dt = 6t^2 - 42t + 60 = 0
t^2 - 7t + 10 = 0
(t - 5)(t - 2) = 0
t = 2 s and 5 s which are the times when the direction is reversed
Position at t = 2 = 2(2)^3 - 21(2)^2 +60(2) + 3 = 55 feet
at t = 5 position = 28 feet
Acceleration = dv/dt = 12t - 42
At t = 2 acceleration = -18 ft s-2
At t = 5 ............... = 18 ft s-2
Answer:
(-2,0) (1,0) (6,0)
Step-by-step explanation:
I used synthetic division which is a lot to explain so I would recommend googling it
Answer:
the desired line is y = 2x+1
Step-by-step explanation:
A line parallel to y=2x+5 has a very similar equation. All we have to do here is to write y=2x+5 as y=2x+b and find b for x = 1 and y = 3.
Replacing y with 3 and x with 1, we get 3 = 2(1) + b. Then b = 1, and the desired line is y = 2x+1
