Gonna do a little subbing here...

for 40 pgs of express proof reading....3 bucks per pg...c = 3
40(3) - 0.05(40(3)) = T
120 - 0.05(120) = T.....120 - 6 = T.....114 = T
so  express proofreading cost 114

for 40 pgs of basic proof reading....c = 3.95
40(3.95) - 0.05(40(3.95) = T
158 - 0.05(158) = T....158 - 7.9 = T.....150.10
so basic proof reading costs 150.10

for 40 pgs of extended proof reading....c = 5
40(5) - 0.05(40(5) = T
200 - 0.05(200) = T....200 - 10 = 190
so extended proof reading is 190

no need to go further....the extended proof reading is gonna be ur answer...the best quality of editing that keeps it at 190

What is the solution to the system of equations below? y = one-half x minus 4 and y = negative 2 x minus 9 (–2, –5) (–2, –3) (2,
Maurinko [17]

We have been given a system of equations y=\frac{1}{2}x-4 and y=-2x-9. We are asked to find the solution of our given system of equations.

To solve our system of equations, we will equate both equations as:

\frac{1}{2}x-4=-2x-9

\frac{1}{2}x-4+4=-2x-9+4

\frac{1}{2}x=-2x-5

\frac{1}{2}x+2x=-2x+2x-5

\frac{1}{2}x+\frac{4}{2}x=-5

\frac{1+4}{2}x=-5

\frac{5}{2}x=-5

\frac{2}{5}\cdot \frac{5}{2}x=-5\cdot \frac{2}{5}

x=-2

Upon substituting x=-2 in equation y=-2x-9, we will get:

y=-2(-2)-9

y=4-9

y=-5

Therefore, the solution of our given system of equations would be (-2,-5) and option A is the correct choice.

Simplify:<br> −z3+5k6−(−z3+10k6)
natta225 [31]

Answer:

The answer to your question is        -5k⁶

Step-by-step explanation:

Polynomial

                                      - z³  + 5k⁶  - (-z³ + 10k⁶)

Use law of signs for the parenthesis

                                     - z³  + 5k⁶ + z³  - 10k⁶

Use associative property for like terms

                                    (-z³ + z³) + (5k⁶ - 10k⁶)

Simplify like terms

                                    (0)  +   (-5k⁶)

Result

                                               -5k⁶
