Answer:
15%
Step-by-step explanation:
Let c represent the regular price of the carpet.
Then:
sale price = regular price less discount
$374 = c - $66
Adding $66 to both sides isolates (solves for) c:
$374 + $66 = c = $440. This is the regular price.
$66
---------- = 0.15 This is the fraction of the regular price by
$440 which the regular price is reduced.
Then the percentage of this discount was 0.15(100%) = 15%
Answer:
<u>x = 8</u>
Step-by-step explanation:
The sides are in proportion.
- 40 / 7x + 14 = 44 / 33 + 44
- 40 / 7x + 14 = 44/77 = 4/7
- 40(7) = 4(7x + 14)
- 280 = 28x + 56
- 10 = x + 2
- <u>x = 8</u>
Answer:
2x-5=y
I'm not sure how your graphing tool works so I'll give you five or so coordinates
(-1,-7)
(1,-3)
(0,-5)
(2,-1)
(-2,-9)
Step-by-step explanation:
You first need to write an equation that you can graph
Knowing that the slope is two we can write the following equation
2x+b=y
We also know that when x=1 y=-3
This gives us 2*1+b=-3
which means that 2+b=-3
subtract 2 from both sides to figure out the b=-3
This means that the line you have to graph is 2x-5=y
Answer:
(0, 11) is a solution.
(8, 12) is a solution.
(16, 13) is a solution
(1, 89/8)
(2, 45/4)
Step-by-step explanation:
y = 1/8x + 11
for this equation....
y = (1/8) x + 11
let x = 0 get
y = 0 + 11 = 11
(0, 11) is a solution.
(8, 12) is a solution.
(16, 13) is a solution
(1, 89/8) because y = 1/8 + 11 = 1/8 + 88/8 = 89/8
(2, 45/4)
