Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x.
364 = 1.40x
Solving for x gives x = 260.
Thus, the autograph of the basketball player was worth only $260 last year.
Answer:
Option (A)
Step-by-step explanation:
By satisfying the equation of a function 'f' by each coordinates given in the options we can get the point which lies on the graph of f(x) = ![2\times (5)^x](https://tex.z-dn.net/?f=2%5Ctimes%20%285%29%5Ex)
Option (A). (1, 10)
f(1) = ![2\times (5)^1](https://tex.z-dn.net/?f=2%5Ctimes%20%285%29%5E1)
10 = 10
True.
Therefore, point (1, 10) lies on the graph.
Option (B). (0, 10)
f(0) = ![2\times 5^0](https://tex.z-dn.net/?f=2%5Ctimes%205%5E0)
10 = 2
Not true.
Therefore, point (0, 10) doesn't lie on the graph.
Option (C). (10, 1)
f(10) = ![2\times 5^{10}](https://tex.z-dn.net/?f=2%5Ctimes%205%5E%7B10%7D)
1 = 19531250
Not true.
Therefore, point (10, 1) doesn't lie on the graph.
Option (D). (0, 0)
f(0) = ![2\times 5^0](https://tex.z-dn.net/?f=2%5Ctimes%205%5E0)
0 = 2
Not True.
Point (0, 0) doesn't lie on the graph.
Option (A) will be the answer.
Hello!
2(x + 9) = 4(x + 7) + 2
Distribute the 2
2x + 18 = 4(x + 7) + 2
Distribute the 4
2x + 18 = 4x + 28 + 2
Combine like terms
2x + 18 = 4x + 30
Subtract 18 from both sides
2x = 4x + 12
Subtract 4x from both sides
-2x = 12
Divide both sides by -2
x = -6
Where she did something different than me is her mistake
