Answer:
a) y = .70x + 20
-To find this, use the rate as x since it will change based on the number of miles. Since 20 is a flat fee, it can be added at the end as a constant.
b) This graph forms a straight line.
-This is because the answer in a is a linear equation.
c) The slope is .70 and the y-intercept is 20.
-For this one, the y-intercept is always the constant at the end of the equation and the slope is the coefficient of x.
x=8
Explanation:
the opposite side is 72, which means I have to make 9x end up equaling 72.
72÷9
////
72/9
=8
9×8=72
<u>Therefore</u>
the value of x is 8.
i think it should be 36%
Step-by-step explanation:
6 and 2/5 times 4 and 1/2 = 28.8 or 28 and 4/5 minutes
=20%
