Which figure could be the result of dilating this triangle with a scale factor greater than 1?
On a coordinate plane, a triangle has points (0, 0, (0, 3), (6, 0).
On a coordinate plane, a triangle has points (0, 0), (0, 3), (9, 0).
On a coordinate plane, a triangle has points (0, 0), (0, 1), (6, 0).
On a coordinate plane, a triangle has points (0, 0), (0, 5), (10, 0).
On a coordinate plane, a triangle has points (0, 0), (0, 2), (4, 0).

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

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
