It is a solution because 26 divided by 2 is equal to 13
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)
Answer:
What's the rest of the question.
Step-by-step explanation:
Subsitte
y=6-x and y=x-2
both equal y so set equal;
6-x=y=x-2
6-x=x-2
add x both sides and addd 2
8=2x
divide 2
4=x
sub back
y=6-x
y=6-4
y=2
(x,y)
(4,2)
answer is C
Answer:
(5 x + 1)-(-10 x + 6)
