Answer:
slope = 1
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (10, 3 ) and (x₂, y₂ ) = (7, 0 )
m =
=
= 1
Answer:
x=14 , y = 21
Step-by-step explanation:
y=x-7...............1
5x+2y=7......2
reset eqn .....2
2y=-5x+7
so; y=-x-7 ×5
2y=-5x+7 ×1
5y = -5x -35
2y = -5x +7
5y-2y = -5 + 5 -35-7
<u>3y</u> = - <u>42</u>
3 3
y = 14
sub y=14 into eqn ...........1
y = -x -7
14 = - x -7
14 +7 = - x
-21 = x
x = 14 , y =-21
3/5 is actually greater than 1/3.
100% - 20% = 80%
$26.95 * 80% = $21.56
You multiply by 80% because you are taking 20% off and now want to know what 80% of the price will be.
Answer:
Z is 66. If you want an explanation, I could give it to you, FYI.
