(2) The ratio of girls to boys at SJAM is 5:6. If there are 730 girls at the school, how many boys are there? How many students are there altogether? Show your thinking by including
all of your steps.

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -f(x)+4

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-12). the y intercept of the second parabola is (0,-24) what is the positive difference between the a values for the two functions that describe the parabolas

If x varies directly as y, and x = 7.5 when y = 10, find x when y = 4
