The answer is B x = -4. x= 3

You must factor the equation by find what 2 numbers can multiply to equal -12 and add to equal 1.

-3 and 4 are the two numbers. Now to put it in factor form would be:

(x - 3)(x + 4) = 0

They y also must equal zero.

Since its equals to 0, we must solve for x for the binomial.

x - 3 = 0 ; x = 3

x + 4 = 0 ; x = -4

The answer you get from solving x, is that answer

Jenny reads 5/8 pages in 2/3 minutes what's the unit rate

LekaFEV [45]

Answer:

15/16 pages in a minute

Step-by-step explanation:

So to make a unit rate, you have to make the denominator 0. So (5/8)/(2/3) is 5/8*3/2 or 15/16. So that would be 15 pages in 16 minutes or 15/16 pages in a minute.

Answer:

M= -2

B=1

Step-by-step explanation:

Y-intercept is the point where the line crosses through the y line, so you can clearly see that that point is (0,1) we only write the y value because for a y intercept the x value will always be zero

Slope is the rise over run, meaning how much the y value changes over how much the x value changes, so for the two points we use our formula:

$\frac{y1-y2}{x1-x2}$
