(-3,3) is the midpoint between the two
Answer:
The answer to your question is 9. (2x - 3)(3x - 4) 10. (x + 4)²
Step-by-step explanation:
9. 6x² - 17x + 12
-Multiply 6 by 12 and find the prime factors of the result
6 x 12 = 72
72 2
36 2
18 2
9 3
3 3
1
-Find two numbers that added gives -17
-These numbers are -8 and -9
-Substitution
6x² - 9x - 8x + 12
-Factor by grouping
3x(2x - 3) - 4(2x - 3)
(2x - 3)(3x - 4)
10. x² + 8x + 16
-Find two numbers that added gives 8 and multiply gives 16
-These numbers are 4 and 4
-Factor like a perfect square trinomial
(x + 4)²
Answer:
15x
Step-by-step explanation:
When a number is next to a variable it means to multiply the two, so just put 15 and x together.
Answer: D: x = {-3, -1, 1}
<u>Step-by-step explanation:</u>
Domain refers to the x-values of the coordinates.
Coordinates are in the form (x, y) so we are looking for the values on the left side of the parenthesis.
(-3, -2) --> x = -3
(-3, 0) --> x = -3 <em>already listed above so no need to list it again</em>
(-1, 2) --> x = -1
(1, 2) --> x = 1
the x-values are: -3, -1, & 1
so the domain is: x = {-3, -1, 1}
The answer is C.
hope this helps
