Answer:

(2, -6)

Step-by-step explanation:

5n^2+20n-60

(5n+30)(n-2)

5n + 30 = 0

5n = -30

(5n = -30)/5

n = - 6

n - 2 = 0

n = 2

If y is proportional to x and y = -15 when x = -20, what is the value of x when y = 12?
Alex
When y=-15, x=-20. So subtract x from y, you will get that y= 0 and x=-5. Add 12 to both and you have your answer, x=7 and y=12

what’s the slope and y intercept of the loire that is perpendicular to y=-2x-5 and passes through the point (-3,-6)
Doss [256]

Answer:

slope: ½

y-intercept: -4½

Step-by-step explanation:

Slope: negative reciprocal of -2

-1/-2 = 1/2

y = ½x + c

-6 = ½(-3) + c

-6 = -3/2 + c

c = -6 + 3/2

c = -9/2 = -4½
