Answer:
66 2/3 cubic inches
Step-by-step explanation:
V=1/3Bh where 'B' is the area of the base and 'h' is height
V = 1/3(20)(10)
V = 200/3 or 66 2/3 cubic inches

Answer:
-8 < x< 3
Step-by-step explanation:
|2x+5| <11
there are two solutions, one positive and one negative ( remember to flip the inequality for the negative)
2x+5 <11 and 2x+5 > -11
Subtract 5 from each side
2x+5-5 < 11-5 and 2x+5-5 > -11-5
2x< 6 and 2x>-16
Divide by 2
2x/2 <6/2 and 2x/2 >-16/2
x <3 and x>-8
-8 < x< 3
x is less than 3 and x is greater than -8
open circles and -8 and 3 and a line between
im not 100% sure if my answers are right but heres what i got:
b. 3 and 1/2
d. 2 and 1/3 (or 2 3/9)
Rewrite it as y=6x-7/5
Flip the x and y
x=6y-7/5
Solve
5x=6y-7
5x+7=6y
5/6x+7/6=y
f^-1(x)=5/6x+7/6
