The value of x in 2^x - 2 when x = 0, x = 1 and x = 2 are -1, 0 and 2 respectively. option A
<h3>Algebra</h3>
2^x - 2
when x = 0
2^x - 2
= 2^0 - 2
= 1 - 2
= -1
when x = 1
2^x - 2
=2^1 - 2
= 2 - 2
= 0
when x = 2
2^x - 2
= 2^2 - 2
= 4 - 2
= 2

2(2x-1) + 2(3x)=4x-2+6x = 10x - 2 & not <span>=10x-1</span>
Let the angle be x
complement 90-x
so the equation will be
3x = 90-x-14
3x+x = 90-14
4x = 76
x=76/4= 19
90-x= 90-19 =71
9.75+9.75+9.75= 29.25 (if you do not include tax). $43.00 - $29.25 = $13.75 so therefore after buying 3 tickets worth $9.75 each, he will have $13.75 left over.
Answer:
5x + 9y ≤ 32
Step-by-step explanation:
Each cassette tape costs $5 and each CD costs $9
Let x represent the number of tapes and y the number of CDs.
The cost of the cassettes is the number of cassettes times the cost per cassette and the cost of the tapes is the number of tapes times the cost per tape. We add these together to get the total cost. The total cost must be less than or equal to 32
32≥5x+9y
