Answer:
5
Step-by-step explanation:
If we consider half the first purchase, it is
2 used + 1 new = $42
And the second purchase is
6 used + 1 new = $78
Subtracting the first of these equations from the second, we get ...
4 used = $(78 -42) = $36
used = $9 . . . . . . . . . . . . . . divide by 4
Then we can find the price of a new game from ...
new = $42 - 2 used = $42 -2·9 = $24
___
The number of used games Janet can purchase on her budget is ...
($120 -3·$24)/$9 = $48/$9 = 5 1/3 ≈ 5
Janet can purchase 5 used and 3 new video games for $120. (and have $3 left)
Answer:
None of the Above
Step-by-step explanation:
The range is [2, ∞) excluding (2, 7) and [11, 16). No part of the piecewise function will give f(x) = 5, for example.
Answer:
5√5
Step-by-step explanation:
You can rewrite √75 as √(25 * 5) and since 25 is a perfect square, you can find the square root and take that outside of the square root. √25 = 5, so √75 is equal to 5√5, and that cannot be simplified furthermore.
Steps to solve:
4 - 3x = 2(x - 3)
~Distribute
4 - 3x = (2 * x) + (2 * -3)
~Simplify
4 - 3x = 2x - 6
~Subtract 4 to both sides
4 - 4 - 3x = 2x - 6 - 4
~Simplify
-3x = 2x - 10
~Subtract 2x to both sides
-3x - 2x = 2x - 2x - 10
~Siimplfy
-5x = -10
~Divide -5 to both sides
-5x/-5 = -10/-5
~Simplify
x = 2
Best of Luck!
