Answer:
y = 3x + 1
Step-by-step explanation:
The way you find slope is change in y over change in x, (as a fraction).
So then your equation is y = 3x because the y value goes up 3 times and the x goes up once (3/1), and then you see what value y has when x = 0 to find the b value, which is one.
Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as then the equation relating them is
c = k ← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k × = 8k ( divide both sides by 8 )
1.75 = k
c = 1.75 ← equation of variation
When d = 324 , then
c = 1.75 × = 1.75 × 18 = 31.5

Answer:
x=0 x = 1/6
Step-by-step explanation:
5x -30x^2 = 0
Factor out the greatest common factor which is 5x
5x(1 -6x) =0
Use the zero product property
5x =0 and 1-6x =0
x =0 -6x = -1
x = -1/-6
x = 1/6
