The first one (0,7) tells you that when x isn't there, the amount of money is 7.

That means that the y intercept is 7.

When x = 1 the total is 15

Money saved = ax + 7

15 = a*1 + 7 Subtract 7

15-7 = a + 7-7

a = 8

The equation is f(x) = 8x + 7

The hypotenuse of a right triangle is 89 meters long. One leg of the triangle is 39 meters long. What is the length of the other

Hitman42 [59]

A²+b²=c²
39²+b²=89²
1521+b²=7921
subtract 1521 from both sides
b²=6400
so then you square both sides
√6400
80
