As the equation is already in <em>y</em>=<em>mx</em>+<em>b</em>, all we need to do is use the equation to draw out a graph (or in this case, match with an already existing graph) using the y-intercept and slope. Since the y-intercept is 5, we can eliminate graphs C and D from our answers. We know the slope is -4, which means that our rise over run is -4 over 1. That would mean, to get from one point to the next, you go down 4 spaces and to the right one. This means the correct answer is graph B.
The quotient is 0.20125.
Solution:
Divide .03220 by .16
This can be written as
To divide this, we first remove the decimal term.
To remove decimal in denominator multiply and divide by 100.
Now, divide 3.22 by 16.
The quotient is 0.20125.

If it takes more than 2 hours to mow the yard.
18 +4x = 12+7x solves to 2, meaning they would cost the same at 2 hours of mowing. So anything larger than 2 hours means Andrew gets $3 more an hour than Jason
Let the hamburgers be x and cheese burgers be y.
x + y = 24
3x + 3.5 y = 79
x = 24 - y.
Substituting the value of x,
3( 24 - y) + 3.5 y = 79
72- 3y + 3.5 y = 79
72 + 0.5 y = 79
0.5y = 79 - 72 = 7
1/2 y = 7
thus, y = 7 * 2 = 14
Substituting the value for x,
x + y = 24
x + 14 = 24
x = 24-14 = 10
Thus, x = 10.
Thus, she sold 10 hamburgers and 14 cheeseburgers
