Start your line at y=15 and for every number on x go up one square
Step-by-step explanation:
r+(−8)=10
r - 8 = 10
r = 10 + 8
r = 18
(substract 8 from 1 side and add it to the other side )
Answer:
Step-by-step explanation:
Let the number of dimes be d and quarters be q
<u>The value is $8.80 = 880¢, so:</u>
- 10d + 25q = 880 ⇒ 2d + 5q = 176
<u>If the dimes were quarters and the quarters were dimes, the coins' total value would be $7.30 or 730¢</u>
- 25d + 10q = 730 ⇒ 5d + 2q = 146
<u>Now we have 2 equations. Solving the system by elimination, subtract 5 times the second equation from twice the first equation:</u>
- 2(2d + 5q) - 5(5d + 2q) = 2(176) - 5(146)
- 4d - 25d = -378
- -21d = -378
- d = -378/-21
- d = 18
Simplify the answer so its ( x+1 over (x-2)(x-4) ) where the answer should be D all real numbers except 2 and 4.
hope it helped !!
