If you would like to know how much did Danielle spend on a long distance, you can calculate this using the following steps:
C = $77.70 - $29.95 for a basic cell phone rate - $5.95 for voice mail - $2.95 for text messaging = 77.70 - 29.95 - 5.95 - 2.95 = $38.85 on a long distance
Danielle spent $38.85 on a long distance.
F(x)=2x³+x-3
f(-2)=2(-2)³+(-2)-3
f(-2)=2(-8)-2-3
f(-2)=-16-2-3
f(-2)=-18-3
f(-2)=-21. As a result,C is your final answer. Hope it help!
Answer: Parenthesis exponents multiply divide add subtract
1. x/6>3 multiply both sides by 6
x>18
So a. and c. are both greater than 18
2.
-4x<32 divide both sides by -4 (and remember to reverse direction of inequality sign because of multiplication/division by a negative value!)
x>-8
So three value of this infinite set are -7, -6, -5 :P
3.
x/6≥3 multiply both sides by 6
x≥18
So three value of this infinite set of solutions are 18,19,20
Slope Formula- y2-y1/x2-x1. So let's plug our x and y's. 8-2/4-6=6/-2=-3. And that's our answer.
