F(x)=x^2-8x+7
find the x-intercepts. write as ordered
pair.

(7,0) and (1,0)

Step-by-step explanation:

To find the x-intercepts, we set the equation equal to 0 and solve. So, we set x²-8x+7 equal to zero and solve. This can be factored as (x-7) and (x-1).

We have (x-7)(x-1)=0

x-7=0 x-1=0

x=7       x=1

X-intercepts: (7,0) and (1,0)

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

i think it might be a but you might want a second opinion
