Y=(x-2)^2 + 5
hope it helps
D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1
Pretty sure it's A. (X times .5 equals Y)
Mark has 5 friends over and he baked 25 cookies. How many cookies does each friend get?
Answer:
4 - 5 = 40 books about travel. 80 are school stories.
6-7 = 30 are about nature. 48
8 =24
9 = 18
10 = 2001
Step-by-step explanation:
<h3>4,5,6,7,8</h3>
1/10 = 24 = sport
1/8 = 30 =nature
1/6= 40 =travel
1/5 = 48 = adventure
1/3 = 80 = schools stories
To get that you just have to read the question, find the fractions, percentages etc.
I put them all into fractions and divide 240 by the denominator.
<h3>9</h3>
For question 9, you just have to add all of the amounts of books together and take that away from the total amount. In this case it is 240 - 222 = 18
<h3>10</h3>
You just have to write it out.
