- y-intercept

19) and 20) you have in other your question.
Answer: A graphical display of data using different heights
Millie can only make 5 quilt squares. If she needs 1 yard of blue fabric and 1 yard of pink fabric to make 1 quilt square and only has 5 yards of blue fabric and 7 yards of pink fabric, she can only make 5 quilt squares.
2-5(-2)=12
2-5(-1)=7
2-5(0)=2
2-5(1)=-3
2-5(2)=-8
If you multiply out the first side of the equation, (x + 5)³, it's equal to the second side.
x³ + 5³ = x³ + 5³, so any value of x would work.
x = "any real number" would be your answer, unless you can't type. then I think anything would work (I'm not certain though!) :)
