Answer:
$5x + $7y ≥ $220
Step-by-step explanation:
Total Fees = $220
Total income is $5x plus $7y
Income = $5x + $7y
We want the total income to be equal to, or greater than, $220:
$5x + $7y ≥ $220
Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:
<em>add 9 to both sides</em>
<em>divide both sides by 2</em>
Parallel lines have the same slope. Therefore we have the equation:
Put the coordinates of the point (4, -4) to the equation:
<em>subtract 14 from both sides</em>
Finally we have the equation:
Two lines are perpendicular to the same line so they are parallel .
Answer:
B: 7t(8s - 3)
Step-by-step explanation:
Method 1: check by expanding each of them
A: 7(8st - 3t)=56st-21t
B: 7t(8s - 3)=56st-2t
C: 3t ( 18s - 7)=54st-21t
D: 7s ( 8t - 3t)=56st-21st
Method 2: the common factors of 56st and 21t is: 7t
56st/7t=8s
-21t/7t=-3
56st-21t=7t(8s-3)
