6. thirty-five more than .8 times a number is the
same as 43 less than the product of -7 and the
number.

n= -75

Step-by-step explanation:

After setting up your equation it should look like this:  35+0.8n=43-(-7-n)

First step is to remove the parenthesis: 35+0.8=43+7+n

Then, you add 43+7 : 35+0.8n=50+n

After that, move the the variable to the left side and change its sign: 35+0.8n-n=50

Then do the same with 35 instead of the variable: 0.8n-n=50-35

Collect like terms: -0.2n=50-35

Subtract the numbers: -0.2=15

Divide both sides by -0.2: n=-75

Hope this helps.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
