Reina is distributing crayons to her five young cousins. Each child will get an equal number of crayons. The number of crayons distributed is represented in the graph
of f(x)=Lx5 ] What piecewise function has the same graph over the

Total number of crayons

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

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
