What is the slope of the line that passes through the points (–20, 18) and (30, 14)? Negative StartFraction 25 Over 2 EndFraction
Negative five-halves
Negative two-fifths
Negative StartFraction 2 Over 25 EndFraction

-2/25

Step-by-step explanation:

m= y2-y1/x2-x1

m=14-18/30 -(-20)

m=-4/50

m=-2/25

understand that i don't know the answers

will someone answer his question

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
