Answer:
what grade is this
Step-by-step explanation:
(6r-1)(-88-3)
Multiply the two brackets together
(6r)(-88)=-528r
(6r)(-3)=18r
(-1)(-88)=88
(-1)(-3)=3
-528r-18r+88+3 ( combine like terms)
Answer: -546r+91
Answer:
-5/2
Step-by-step explanation:
with slope always remember rise over run, vertically, the dots are 5 points away from each other so that is your rise. Horizontally they are only 2 away so that's your run. the answer is negative because the slope goes down to the right. If it went up to the right then the slope would be positive.

Answer:
63.5 in
Step-by-step explanation:
y2-y1/x2-x1
28.5-21/2.5-1 = 5
y=mx+b
21=5(1)+b
21-5= 16
b=16
y=mx+b
y=5(9.5) + 16
=63.5
