Answer:
m=-2n-13
Step-by-step explanation:
m+1=-2(n+6)
m+1=-2n-12
-1. -1
--------------------
m=-2n-13
40,000 is 10 times as much as 4,000
Answer:
c. -x + 3x + 7 = 2x+7
Step-by-step explanation:
f(x) = 3x +1 and g(x) = x - 6
f-g = 3x +1 - ( x - 6)
Distribute the minus sign
= 3x+1 - x+6
= 2x +7

Now, Finding the New selling price
![\sf{New \: SP \: ( \: selling \: price)} = \frac{19x}{20} + 5200](https://tex.z-dn.net/?f=%20%5Csf%7BNew%20%5C%3A%20SP%20%5C%3A%20%28%20%5C%3A%20selling%20%5C%3A%20price%29%7D%20%3D%20%20%5Cfrac%7B19x%7D%7B20%7D%20%20%2B%205200)

Finally, finding the Cost price :
We have, Profit % = 8 %

Answer:
C is correct
Step-by-step explanation:
Comparing the to equation with slope intercept form: ![y=mx+c](https://tex.z-dn.net/?f=y%3Dmx%2Bc)
The second equation has the greatest slope, which is indicating that the line is steeper.
