Answer:
A and C
Step-by-step explanation:
It can not be D, since that will mean that <em>the line is perfectly horizontal</em>, with 0 as its slope.
It can be C, since the <em>equation's slope is positive and has a negative y-intercept</em>, like the graph.
Changing around A gives us y = 2x - 3. That has a <em>positive slope and a negative y-intercept</em>, like the graph. So, A is a possibility.
Changing around B gives us y = ²/₃x + 3. This has a positive slope, <em>but also a positive y-intercept</em>, so B can not be the answer.
4x^2 + 5x - 6 = (4x - 3) (x + 2)
You can do it by using the quadratic function to solve 4x^2 + 5x - 6 = 0; the result will be x = 3/4 and x = -2
Then you have to make (x- 3/4) = 0 and (x +2 ) = 0
When you develop x - 3/4 = 0 you get 4x -3 = 0, which means that 4x - 3 is a factor. The other factor is directly x + 2.
Answer: option b: (4x -3)(x + 2)
Answer:
7
Step-by-step explanation:
1) "x is 23 more than 3 times y" is the same thing as "x = 23 + 3y"
REMEMBER: when you see "is" replace is with an equals sign.
2) Solve for x with your new equation.
3) Plug 6 into the y ("y = 6")
x = 23 + 3 x 6... x = 23 + 18... x = 41
4) Plug in your variables, and evaluate.
(41 - 6)/5... 35/5... 7!
