all you have to do next is add all of them in one equation and equate them to 18
when you find x, replace in each expression to get your answers
Answer: m = -1/3
Step-by-step explanation:
1.5x + 4.5y = 18
convert to the formula y = mx + b we have
4.5y = -1.5x + 18
y = (-1.5/4.5)x + 18/4.5
y = -1/3x + 12
(ax-by)²+(bx+ay)²
a²x²-2axby+b²y²+b²x²+2axby+a²x²
a²x²+b²x²+b²y²+a²x²
(a²+b²)x²+(a²+b²)y²
(a²+b²)(x²+y²)
If u can plz give more information I am more than glad to help out
I think this is right x+5z+5
