Answer:
k = 8
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 32 when x = 4, then
32 = 4k ( divide both sides by 4 )
8 = k
You just have to find what x is. Pretend there isn't the signs and think of it as = signs. Then whatever u do on one side do it to all of them
Answer:

Collect like terms
-3x + 31
Answer:
0
Step-by-step explanation:
Slope = y2- y1/x2 - x1
Given
x1 = 6
y1 = -3
x2 = -4
y2 = -3
Slope = -3 -(-3) /-4 - 6
= -3 + 3 /-10
= 0/10
= 0
This means that the line of the slope is horizontal
Answer:
56 mph
Step-by-step explanation:
