Answer:

(x-10) (x+1) =0

x=10 x=-1

Step-by-step explanation:

x^2 -9x-10 =0

Factor

What two numbers multiply to -10 and add to -9

-10*1 = -10

-10+1=-9

(x-10) (x+1) =0

Using the zero product property

x-10 = 0 x+1=0

x-10+10=0+10 x+1-1=0-1

x=10 x=-1

These are the x intercepts

Emily thought of a counting number, and then she added the next counting number to it. She got the sum of 57. What was Emily’s n

Dovator [93]

Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57
$2x=56$
$x=28$
Emily's number was 28
