Answer:
A. x=3
Step-by-step explanation:
Solve for x:
4x+10+3x=40-3x
7x+10=40-3x
+3x +3x
10x+10=40
-10 -10
10x=30
/10 /10
x=3
I believe it is B, but I'm still unsure !
Answer: x =2
Step-by-step explanation:
5x - 8 = 3x - 4
2x = 4
x = 2
checking the work:
5(2) - 8 = 3(2) - 4
10 - 8 = 6 - 4
2 = 2
We are given the distance as a function of time:
s = 4.9 t^2 + 350
To get the velocity, we take the first derivative and
substitute the value of t = 2:
ds = 9.8 t dt
ds / dt = 9.8 t
velocity = 9.8 (2)
<span>velocity = 19.6 m/s</span>
B I think.....................
