Answer:
Step-by-step explanation:
We are given: 
So, the integral will be used to calculate the volume.
I one is 8x<24 and -8≤2x-4
Hence x <24/8 =3 and -4≤2x: divide by positive 2 to get -2≤x
Hence solution is -2≤x<3
Therefore c is the correct matching for 1.
2) 5x-2>13 or -4x≥8
i.e. 5x>15 or x≤8/(-4) = -2 (since dividing by negative inequality reverses)
Or x>3 or x ≤-2
Hence solution is two regions to the right of 3 excluding 3 and left of -2 including -2.
Graph b is the correct match.
3) -25≤9x+2<20
Subtract 2
-27≤9x<18: Now divide by positive 9
-3≤x<2
Hence graph is the region between -3 and 2 including only -3.
Graph a is correct matching for question 3.
Answer: 250=70x+50
Step-by-step explanation:
250 being the total would go at the equal sign
250=
And since it says 70 Per car that means it would be 70x so
250=70x
50 dollars in tips is a total so
250=70x+50 is your equation
Answer:
b)252 is the answer
Step-by-step explanation:
x\42=6
x=6*42
x=252
