Answer:
She needs 153
Step-by-step explanation:
Let x be the score in the 4th game
To find the average add up the scores and divide by the number of scores added
(149+162+152+x) /4 = 154
Multiply each side by 4
(149+162+152+x) /4 *4= 154*4
(149+162+152+x) = 616
Combine like terms
x+463=616
Subtract 463 from each side
x+463-463 = 616-465
x = 153
The function is not invertible if you think of it as

because it is not injective: 
So, if we restrict the domain to the positive numbers only:

Note that the range is actually
, so we can be more precise and write

To find the inverse, we solve the expression for x:

But since we restricted to positive values of x, the inverse is

Answer:
Here are the three equivalent fractions of 5/8.
10/16 15/24 20/32
Answer:
6.5 = x
Step-by-step explanation:
(x - 4)2 = 5
2*x + 2*-4 = 5
2x - 8 = 5
2x = 13
x = 6.5
g(x) = -(x + 1)^2 - 3
Let's simplify this equation
g(x) = -(x^2 + 2x + 1) - 3
Distribute the negative sign
g(x) = -x^2 - 2x + 1 - 3
Combine like terms
g(x) = -x^2 - 2x - 2
The value of a = -2 and this value is LESS THAN 0
