4x^3+6x^2-9x+1 is an example
Answer:
Step-by-step explanation:
First, you must find the slope of the line using the formula (y2-y1/x2-x1). For your problem that would be (8-0/-2-4)= -4/3.
Then, you would plug in the slope and the y-intercept into the slope-intercept formula (y=mx+b), where m is the slope and b is the y intercept (4).
Your answer would be y=-4/3x+4
- 2x + 3 > x + 24
First we must get all variables on the same side and constants on the opposite side. To do so we subtract x from the right and the left. Then subtract 3 from both sides as well.
- 2x - x > 24 - 3
Now we combine like terms:
- 3x > 21
We must isolate the variable x. In order to do so, we divide both sides by - 3. When you divide by a negative number, you must also flip the inequality so the greater than becomes a less than.
x < 21 / - 3
x < - 7 is your answer.
Answer: x=-5 x=2
Step-by-step explanation:
x^2+5x-2x-10=0 factor out x from the expression
Xx(x+5)-2x-10=0 factor out x+5 from the expression
(x+5)x(x-2)=0 when the product of factors equals 0, at least one factor is 0
x+5=0 solve for the equation x
x-2=0
x=-5
x=2
