49=-7k is equivalent to D because when you simplify both of them, you get -7=k
Answer:
y= 36
Step-by-step explanation:
if y varies directly as x, and y=9 when x=4, find y when x=16
.
When you see "direct variation" think:
y = kx
.
To find k, use "y=9 when x=4":
y = kx
9 = k(4)
9/4 = k
.
so, our equation is:
y = (9/4)x
.
now, we can answer:
find y when x=16
y = (9/4)x
y = (9/4)(16)
y = (9)(4)
y = 36
V = a^3
10 * 10 * 10 = 1000 cm
