X^2-9x=-8
x^2-9x+8=-8+8
x^2-9x+8=0
(x-8)(x-1)=0
x-8=0
x-8+8=0+8
x=8
x-1=0
x-1+1=0+1
x=1
There are 2 solutions, which are 1 and 8

Answer:
D is the correct answer.
Step-by-step explanation:
You would add $6.00 to $13.20, making 19.20, subtracting 4 x $1.55 (6.2) leaves you with $13, the cost of the pizza. So therefore, it would be 4d + $13.00 – $6.00 = $13.20; $1.55.

Answer:</h2>
<em>You will bike 30.2 miles in the seventh day according to the prediction.</em>
<h2>
Explanation:</h2>
Here we have the following data, You bike
- 5  miles the first day of your training,
- 5.4 miles the second day,
- 6.2 miles the third day, and
- 7.8 miles the fourth day.
So we can know some facts:
- From the first day to the second day the number of miles increases:

- From the second day to the third day the number of miles increases:

- From the third day to the fourth day the number of miles increases:

By taking a look at the pattern, we can see that each day you increases the number of miles by a factor of 2 compared to the previous day. So:
- From the fourth day to the fifth day the number of miles increases:

- From the fifth day to the sixth day the number of miles increases:

Finally:
- From the sixth day to the seventh day the number of miles increases:
