$17-7(x-3)+x=86\\\\
17-7x+21+x=86\\\\
38-6x=86\ \ \ \ |Subtract\ 38\\\\
-6x=48\ \ \ |Divide\ by\ -6\\\\
x=-8\\\\ Solution\ is\ x=-8.$

gregori [183]

Answer:

y = $\frac{5^{x} }{2}$

Step-by-step explanation:

y = log 5 2x

inverse ------> y=x

x = log 5 2y

$5^{x} = 2y$

y = $\frac{5^{x} }{2}$

Sonic rolls up a slope at 9.4 m/s. after 3.0 he is rolling back down ay 7.4 m/s. how far up the hill is he at this time?

vovikov84 [41]

U= 9.4m/s
v= -7.4m/s (Negative sign because it is in the opposite direction as he is rolling back)
t= ?
s= ?
a= ?
Now, a= v-u/t
= -7.4-9.4÷3
=-5.6
By the second equation of motion.
s= ut+1÷2at*2 ( *2 is the power)
s= 9.4×3+1÷2×-5.6×3*2
= 28.2 +(-25.2)
=3
Therefore s or the distance travelled is 3m.
