Y is proportional to the square of x. When x = 10, y = 500. Find a formula connecting y & x and use it to find the value of y when x = 3.
у

y = 45

Step-by-step explanation:

y = k x^2

500 = k * 10^2

500 = k*100

k = 5

y = 5*x^2

x = 3

y = 5*3^2

y = 45

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70
