For each of the ordered pairs, the x coordinate is squared to find y.
x = 1
1^2 = 1
x = 2
2^2 = 4
x = 3
3^2 = 9
x = 4
4^2 = 16

Step-by-step explanation:
<u>Step 1: Define</u>
2(3x - 1) ≥ 4x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 6x - 2 ≥ 4x - 6
- Subtract 4x on both sides: 2x - 2 ≥ -6
- Add 2 on both sides: 2x ≥ -4
- Divide 2 on both sides: x ≥ -2
Here we see that any value <em>x</em> greater than or equal to -2 would work as a solution.
6 x 5 = 30
4 x 4 = 16
30 + 16 = 46
There are 46 DVDs in total.
Answer:
x=−4.350480,−1.669843,7.020324
Step-by-step explanation:
Step 1: Multiply both sides by -x+5.
−x3+x2+34x+56=−x+5
−x3+x2+34x+56−(−x+5)=−x+5−(−x+5)(Subtract -x+5 from both sides)
−x3+x2+35x+51=0
(Use cubic formula)
x=−4.35048,−1.669844,7.020324
Check answers. (Plug them in to make sure they work.)
