X=2, x=-1 so the answer choice would be the third one.
Answer:
x=2
Step-by-step explanation:
12x^2+5x-4 = 12x^2+6
Subtract 12x^2 from each side
12^x2-12x^2+5x-4 = 12^2x-12x^2+6
5x-4 = 6
Add 4 to each side
5x-4+4 = 6+4
5x = 10
Divide each side by 5
5x/5 = 10/5
x = 2
Answer:
The last Table
Step-by-step explanation:
After 2 hours of work, you will be charged $80. Add this to the already charged $650 and you will have $730. For each hour add an additional $40 to that cost. The last table matches this.
1. Integers numbers are defined as the set of numbers that is formed by Positive numbers, which are also called "Natural numbers"; Negative numbers (They are less than zero) and zero (This has no sign). This set is represented with the letter "Z". Therefore: Z={...-2, -1, 0, 1, 2 ...}.
2. So, if 12 is added to the square of a positive integer, you can write the following the expression:
12+x²=133
3. You can obtain the value of the positive integer "x", by clearing it. Then, you have:
12+x²=133
x²=133-12
x=√(133-12)
x=√121
x=11
Therefore, the positive integer is: 11
V = whl
V = 3 1/2 * 4 1/2 * 2
answer
3 1/2 * 4 1/2 * 2
15 3/4 * 2
