Answer:
the answer would be -18
Step-by-step explanation:
3+3=6 2×6=12. 7+3=10 3×10=30 12-30= -18
The slope is 1, -3 - 2 over 0 - 5 = -5/-5 which = 1
Answer: 53%
Step-by-step explanation: First this problem we will use the "Percent Error" equation to solve.
difference = percent error x actual
First, subtract the values 8 - 17, which equals -9, but find the absolute value of -9, which is 9. Lets plug in 9 to the equation. 17 belongs in the "actual category" since 8 was to 17.
9 = percent error x 17
9/17 = percent error
About 0.53 = percent error
Now, to get your percent, multiply 0.53 x 100, which equals 53.
So the percent error from 8 to 17 is 53%
Answer:
Initial cost for a job = $2
Step-by-step explanation:
Let initial cost be $x.
Fixed amount for each copied page = $y
John:
Fixed amount for 425 pages = 425*y = 425 y
x + 425y = 10.50 ---------------(i)
Peter:
Fixed amount for 300 pages = 300 * y =300y
x + 300y = 8 ---------------------(ii)
Multiply (ii) by (-1) and add the both equation. Thus x will be eliminated.
(i) x + 425y = 10.50
(ii)*(-1) <u>-x - 300 y = - 8</u>
125y = 2.50
y = 2.50/125
y = $ 0.02
Plug in y value in equation (i)
x + 425*0.02 = 10.50
x + 8.50 = 10.50
x = 10.50 - 8.50
x = $2
