The answer would be 680 because 20% of 850 is 170 so 850-170=680.
If solving for x you will first need to combine like terms. Then after getting the amount of numbers and amount of x numbers you will divide the x number from both. After doing that you would get X=-10
Answer: y=4/5x-2 or y=4/5x+(-2)
Step-by-step explanation:
The formula for slope-intercept form is y=mx+b.
To find the slope, we can use the formula
and plugging in the points given.

We know our slope is 4/5. We can plug this into our slope-intercept form and then plug in a point to find b, y-intercept.




We know the y-intercept is -2.
THe final equation is y=4/5x-2 or y=4/5x+(-2).
Answer:
The domain is Al real numbers and the range is -5
