Answer:
Points of the triangle: (-6, 3) (-3, 9) (-7, 8)
Step-by-step explanation:
(2, -5) → (-6, 3)
(8, -2) → (-3, 9)
(7, -6) → (-7, 8)
Answer:
- g(x) = x^2 – 4x – 21
- g(x) = 3x^2 – 12x – 63
- g(x) = –(x + 3)(x – 7)
Step-by-step explanation:
When r is an x-intercept of the function, (x -r) is a factor. The two given x-intercepts mean that two factors of the function are (x -(-3))(x -7). There may be a vertical scale factor that is not necessarily positive.
These factors multiply out to give ...
(x +3)(x -7) = x^2 -4x -21 . . . . . . matches the first choice
When this expression is multiplied by 3, it matches the third choice:
3(x +3)(x -7) = 3x^2 -12x -63
When the factored form is multiplied by -1, it matches the fourth choice:
-(x +3)(x -7)
You can make this into an inequality, using x as the number of uniforms.
100 + 12x < 61 + 15x
39 < 3x
13 < x, so they must buy more than 13 to get a better deal.
Answer:
25
Step-by-step explanation:
Find factors of:
25: 1, 5, 25
50: 1, 2, 5, 10, 25, 50
100: 1, 2, 4, 5, 10, 20, 25, 50, 100
Reduce possibilities to only <u>common</u> factors
25: 1, 5, 25
50: 1, 5, 25
100: 1, 5, 25
The greatest of these factors is 25
Greatest Common Factor (GCF) = 25
Hope this helps :)
