Answer:
x^7
Step-by-step explanation:
Answer: -11
Step-by-step explanation:
n+n+1+n+2=-33
n+n+n+1+2=-33
3n=-33-1-2
3n=-36
n=-12
n+1= ==> middle integer
-12+1=-11
Answer:
c)
Step-by-step explanation:
(-4,2) ; (4,-5)
![Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-5-2}{4-[-4]}\\\\=\frac{-7}{4+4}\\\\=\frac{-7}{8}](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-5-2%7D%7B4-%5B-4%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-7%7D%7B4%2B4%7D%5C%5C%5C%5C%3D%5Cfrac%7B-7%7D%7B8%7D)
m = -7/8 ; (-4,2)
equation: y - y1 = m(x - x1)
![y-2=\frac{-7}{8}(x-[-4])\\\\y-2=\frac{-7}{8}(x+4)\\\\y-2=\frac{-7}{8}x +\frac{-7}{8}*4\\\\y=\frac{-7}{8}x-\frac{7}{2}+2\\\\y=\frac{-7}{8}x-\frac{7}{2}+\frac{4}{2}\\\\y=\frac{-7}{8}x-\frac{3}{2}\\](https://tex.z-dn.net/?f=y-2%3D%5Cfrac%7B-7%7D%7B8%7D%28x-%5B-4%5D%29%5C%5C%5C%5Cy-2%3D%5Cfrac%7B-7%7D%7B8%7D%28x%2B4%29%5C%5C%5C%5Cy-2%3D%5Cfrac%7B-7%7D%7B8%7Dx%20%2B%5Cfrac%7B-7%7D%7B8%7D%2A4%5C%5C%5C%5Cy%3D%5Cfrac%7B-7%7D%7B8%7Dx-%5Cfrac%7B7%7D%7B2%7D%2B2%5C%5C%5C%5Cy%3D%5Cfrac%7B-7%7D%7B8%7Dx-%5Cfrac%7B7%7D%7B2%7D%2B%5Cfrac%7B4%7D%7B2%7D%5C%5C%5C%5Cy%3D%5Cfrac%7B-7%7D%7B8%7Dx-%5Cfrac%7B3%7D%7B2%7D%5C%5C)
The independent variable is the variable that changes. In this case, that's the amount of cars washed per day. The dependent variable is the measured variable, which depends on the changed variable. In this case, it's the money collected.
$120/12=$10 per car
$10x30=$300
4/12 and 6/18 because all the fractions (2/6,4/12, and 6/18) reduce down to 1/4.
