Answer:
D. -20 + 35c
Step-by-step explanation:
<em><u>All you need to do is distribute the -5 to what's inside the parenthesis:</u></em>
-5(4 - 7c)
<em><u>The -5 can be distributed to the 4 and the -7c:</u></em>
-20 + 35c
John paid $0.10 more per ballon
John
$4.80/3=$1.60 per ballon
Karen
$6/4=$1.50 per ballon
$1.60-$1.50=$0.10
The answer is
2000 x 0.085 = 170
The slope can be found by using the slope formula.
Slope = y2 - y1 / x2 - x1
First, we need two points on the line.
(-1, 0) and (0, 1)
x1 = -1 and y1 = 0
x2 = 0 and y2 = 1
Let's plug these values into our slope formula.
(1 - 0) / (0 - (-1)) = 1 / 1 = 1
The slope is 1
