What graph equation is parallel to the graph 8x - 2y = 30?

Any graph with the same slope but with different y intercepts is parallel to that. For example in y = mx + b form the equation will be

y = 4x - 15

So, some equations that will be parallel

y = 4x

y = 4x - 16

y = 4x +3

Hoped this helped ya :)

Red paint needed = x = 17.5 ounces

Step-by-step explanation:

Ratio of red to blue paint = 5 ounces : 6 ounces

If she has 21 ounces of blue paint, how much red paint will she need?

Ratio of red to blue paint = x ounces : 21 ounces

Equate the ratios

5 : 6 = x : 21

5/6 = x/21

Cross multiply

5*21 = 6*x

105 = 6x

x = 105/6

x = 17.5 ounces

Red paint needed = x = 17.5 ounces
