The number of miles Melody rides her bicycle, m, varies directly with the amount of time spent riding the bike, t. When Melody b
ikes for 1.5 h, she travels 10.5 mi. Which equation shows this direct linear variation?
A.
m = 7t
B.
m = 7.5t
C.
m = 12t
D.
m = 15.75t
i think its B
1 answer:
It is A.
"When Melody bikes for 1.5 h, she travels 10.5 mi.", therefore her speed is 10.5/1.5 = 7 mi/hr. So the right equation is <span>m = 7t.</span>

I cant see the pic
Step-by-step explanation:
1
k^2 = 4k
k = 0, k = 4
#2
k^2 - 5k = k + 7
k^2 - 6k = 7
k^2 - 6k + 9 = 16
k - 3 = 4 ⇒ k = 7
k - 3 = -4 ⇒ k = -1
#3
k^3 - 5k^2 + 3k = -k
k^3 - 5k^2 + 4k = 0
k(k^2 - 5k + 4) = 0
k = 0, k = 1, k = 4
#4
|k + 1| + 2 = 8
|k + 1| = 6
k = 5, k = -7

Answer:
<h2>f(8) = 74</h2>
Step-by-step explanation:
f(x) = x² + 3x – 14
Then
f(8) = 8² + 3(8) – 14
= 64 + 24 - 14
= 64 + 10
= 74
