Answer:
Step-by-step explanation:
cost of playing x games at Adams = 7.50 + 0.45x
cost of playing x games at Jims = 1.25x
1.25x = 7.50 + 0.45x
1.25-0.45x = 7.50
0.80x = 7.50
x = 7.50/0.80 = 9.375 , but x must be an integer.
The cost is never the same. When x ≤ 9, Adams costs more. When x ≥ 10, Jims costs more.
Answer:
6x = 16
Step-by-step explanation:
Given:
The equation can be rewritten as:
Multiply both sides by 2x.
Simplify the equation in simplest form.
Therefore, the answer to this question is 6x = 16.

Answer:
The relation is a function!
Your Domain should be...
{-1, 1, 7, 9}
Your Range should be...
{-1, 8, 9}
WHY?
Your domain is always your x-coordinates, which are the first coordinates in a pair.
Your range is always your y-coordinates, which are the second coordinates in a pair.
When listing the points, it's important to remain a relation CANNOT be a function if the x's repeat, so luckily, they do not repeat.
Also, when listing points for your range, remember, if they repeat, you should only count one of the numbers, as you can see from the answer, there was two nines, but instead I put one.
Answer:
Step-by-step explanation:
<u>According to intersecting chords theorem:</u>
- 21(2x - 6) = 30(x + 1)
- 42x - 126 = 30x + 30
- 42x - 30x = 126 + 30
- 12x = 156
- x = 156/12
- x = 13
