Answer:C.45
Step-by-step explanation:
So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y
she wants to spend 15 dollars more on sisters than nephews
so
x=15+y
solve
we have
180=3x+2y and
x=15+y
subsitute 15+y for x
180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y
solve for x
x=15+y
x=15+27
x=42
she spent $42 on each sister
K is the constant in a table or equation. like k=x•y
Answer:
as x increases, y increses
the parabola grows wider and taller, meaning that the y and x values will both increase:)
