The rate will be:
(area mowed)/(time taken)
=1017/9
=113 sq. feet/ min
You're basically multiplying the number and the variable with the number on the outside of the parenthesis.
So, 8(x + 7). You multiply 8 and the variable to get 8x. The same with '7'.
8 times 7 is 56.
Answers:
A) 8x + 56
B) 66 + 6x
C) 8x + 8
First of all, we need to know what a function is.
A function is a binary relation between two sets that
The point-slope form:

m - slope
(x₁, y₁) - the point
The formula of a slope:

We have the points (5, 4) and (2, -2). Substitute:

- <em>point-slope form</em>
<em>add 4 to both sides</em>
- <em>slope-intercept form</em>
<em>subtract 2x from both sides</em>
<em>change the signs</em>
- <em>standard form</em>

From the table we have two points (1, 3) and (2, 7). SubstituteL

- <em>point-slope form</em>
<em>add 3 to both sides</em>
- <em>slope-intercept form</em>
<em>subtract 4x from both sides</em>
<em>change the signs</em>
- <em>standard form</em>
