Answer: xsquared + 9x - 11
Step-by-step explanation:
The equation looks like this:
26=x*3.5+8.50
where x is the number of pen you bought.
We solve it like this:
first, we subtract 8.50 from both sides:
17.50 =3.5*x
now we divide both sides by 3.5:
5=x
so you purchased 5 pens.
Pretty sure it is D
if you solve for the intercepts you get these answers
y-intercept is 6
x intercept is 2

The angle supplementary to x and 3x are equal.
Supplementary angles = 180
Solution
x + 3x = 180
4x = 180 Divide by 4
4x/4 = 180/4
x = 45
The angle supplementary to x is 3x
3x = 3*45
3x = 135
This angle is vertically opposite y. Vertically opposite angles are equal. So y = 135
Answer
x = 45
y = 135
Answer:
it would be 20
Step-by-step explanation:
because you divide to find the unit rate like 97.50/15 and then you multiply a number to the answer you got there until those two numbers have a product of 130
