Answer:
The correct answer is B) (x - 5)(x + 10)
Step-by-step explanation:
The constants at the end of the parenthesis need to add to the middle term
10 + -5 = 5
And they need to multiply to the end term
-5 * 10 = -50
This makes it the correct choice.
Answer:
b. 720
Step-by-step explanation:
For number 1, the x-intercept is -1.5 and the y- intercept is 3. For number 2, the x-intercept is 8 and the y-intercept is -4. For number 3, the x-intercept is -10 and the y-intercept is 5. To get these answers, use the formula of y=mx+b. M is the slope and b is the y-intercept so, for number 3, you need to divide everything by -2 to get y alone, then add 1/2 to both sides to use inverse operations. The real equation for number 3 is y=1/2x+5.
Answer:
I think they're both trick questions because there are no like terms
