Answer:
Yes, he is correct
Step-by-step explanation:
25% of 20 is 5 (0.25*20)
100% of 20 is 20
if you take 125% of 20, you'll end up with 25
Answer:
C
Step-by-step explanation:
If you simplify the equation you get 
. To solve a square root function, you need to set up
. You can take the square root of both sides to get 
. Then, we identify the intervals that will satisfy the equation, which is -3 ≤ x < 1.
Sorry if the explanation is kind of confusing, I wasn't sure how to describe it.
765 / 9 = 85
9*100 = 900 but this is too much
900 - 765 = 135
9 goes into 135 15 times (9*10=90 which leaves 45 which is 9*5 so 5+10) so you minus 15 from the 100 that made 900
so 100 - 15 = 85
1. Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. To answer this question, plug in the values they have given you.
y=mx+b
y=1/4x-5
2. To write an equation in slope-intercept form when given two points, use m=y2-y1/x2-x1
Remember: in an ordered pair, x comes first then y.
Plug the y- and x-values in. So, y2=6, y1=2 and x2=-2, x1=9
6-(-)2/-2-9= - 4/11.
The slope of your next equation would be m= - 4/11
