9. X=7. 7-8=-1
8. X=18. 18-7=11
Point-slope form is y - y1 = m(x - x1). If you apply that point and the slope to the formula (hence the name point-slope), you'd get y - 10 = -5(x + 8).
Hope this helps! :)
REVISE: I accidently put y instead of x in the -5(x + 8) part. It's fixed now.
$5.50. if he washes his dog every week, he is getting $6.60 automatically. So if we do simple math, 12.10-6.60= 5.50
Hey there.
When writing a polynomial in standard form, you always want to start from the highest degree (exponent), so let's simplify our expression before doing so.
-2

+ 6

= 4

;
This number will go first as it has the highest degree.
Up next will be '-3x', as it has a degree of 1.
After this, we have 6, having a degree of 0.
Let's set up our new polynomial with this information;
4

- 3x + 6.
This is known as a
cubic trinomial since it has three terms and has a degree of 3.
Your correct answer is
"D.)"
I hope this helps!
