Which of the following functions best describes this graph?
A. y = x^2 - 8x +18
B. y = (x+4)(x+5)
C. y = x^2 -9x +20
D. y = (x-3)(x+4)
Answer:
C
Step-by-step explanation:
Looking at the graph, we can see the roots at two points
these are points x = 4 and x = 5
This can be written in their linear forms as;
x-4 and x-5
Finding the products of both, we have
x(x-5) -4(x-5)
= x^2 -5x -4x + 20
= x^2 - 9x + 20
Ava buys a book for $8.85 .she pays $10 bill.How much chang will see get?
Given:
Ava buys a book for $8.85 .
She pays $10 bill.
To find:
The amount of change she will get.
Solution:
We have,
Price of book = $8.85
Amount she pays = $10
Now,
Amount of change = Amount she pays - Price of nook
Amount of change = $10 - $8.85
Amount of change = $1.15
Therefore, she will get $1.15 as change.
Answer:
1.15
Step-by-step explanation:

Katie is purchasing plates and mugs for her house.
She would like to buy at least 8 items. Plates cost
$8 each and the mugs cost $7 each, and she plans
to spend no more than $112. Write a system to
model the situation and then solve.
Step-by-step explanation:
Plate: $8 each
Mug: $7 each
Spend Limit: $112
Items Wanted: 8
Considering she wants eight items, she can split that in half and buy four of each item, plate and mug.
8 * 4 = 32
$32 for 4 plates.
7 * 4 = 28
$28 for 4 mugs.
However, if she wanted to spend all the money, she could buy a few more of each item.

Solve the equation.
x over four – 5 = –8
A. –27
B. –12
C. –7
D. 12
x/4 - 5 = -8
=> x/4 = -8 + 5
=> x/4 = -3
=> x = -3 × 4
=> x = -12
So, answer is B. –12

Answer:
(0, 13)
Step-by-step explanation:
The midpoint is halfway between the line segment. First find the distance from the starting point to the midpoint.
2-1 = 1. So Since the midpoint is behind the start point, we are going backwards (moving to the left on the x axis).
So 1 space left from the midpoint is 1-1=0.
For y, the distance between the start and mid is 6 - -1 = 6+1 = 7 spaces. Then add 7 spaces to the midpoint value of 6, so 7+6 = 13. We moved upwards on the y axis.

An example is:
Alana has 2 1/4 bags of chocolate chips that she wants to use in 3 batches of chocolate chip cookies. How much of the chocolate chips will she use in each batch of cookies?
Answer:
1 1/3 bags of chocolate chips
Step-by-step explanation:
If Alana has 2 1/4 bags of chocolate chips that she wants to use in 3 batches of chocolate chip cookies, then we can say;
2 1/4 bags of cookies = 3 batches of chips
To determine how much of the chocolate chips will she use in each batch of cookies, we can say;
1 bag of cookies = x batches of chips
Equating both expressions
2 1/4 bags of cookies = 3 batches of chips
1 bag of cookies = x batches of chips
Cross multiply
2 1/4 x = 3
9/4 x = 3
9x/4 = 3
9x = 12
x = 12/9
x = 4/3
x = 1 1/3
Hence Alana will need 1 1/3 bags of chocolate chips

Answer:
∠ JHF = 69°
Step-by-step explanation:
Since HJ is a midline then it is parallel to EG , thus
∠ JHF and ∠ GEH are corresponding and congruent, then
7x + 62 = 79 - 10x ( add 10x to both sides )
17x + 62 = 79 ( subtract 62 from both sides )
17x = 17 ( divide both sides by 17 )
x = 1
Thus
∠ JHF = 7x + 62 = 7(1) + 62 = 7 + 62 = 69°
Answer:
7x + 62 = 180
7x= 180 - 62
x = 118 / 7
x = 16
7 × x = 7 × 16
112 + 62 = 174

This week, Tori ate 600 g of cheerios cereal.
That was 150% as much cereal as she ate last
week. How much cereal did Tori eat last week?
600 g is 150% of what number?
Step-by-step explanation:
600=150%
?= 100%
crossmultiplication
=400
600g=150%x
600 is therefore 150% of 400

Ty is placing CDs in boxes. There are a total of 7,200 CDs. Each box holds 90 CDs. How many boxes will Ty fill? A. 80 B. 70 C. 100 D. 90
Answer:
80 boxes.
Step-by-step explanation:
Total CDs available = 7200CDs
Amount of CD in each box = 90 CDs
To get the number of boxed Ty will fill, we will say;
90CDs = 1box
7200 CDs = x
Cross multiply
90 * x = 7200 * 1
90x = 7200
x = 7200/90
x = 80
Hence Ty will fill total of 80 boxes.
Answer:
80 CDS
Step-by-step explanation:
Total CDs available = 7200CDs
Amount of CD in each box = 90 CDs
To get the number of boxed Ty will fill, we will say;
90CDs = 1box
7200 CDs = x
Cross multiply
90 * x = 7200 * 1
90x = 7200
x = 7200/90
x = 80
Hence Ty will fill total of 80 boxes.
The residents of a city voted on wether to raise property taxes. The ratio of yes votes to no votes was 8 to 5. If there was 6856 yes votes, what was the total number of votes
Answer:
The total number of votes cast in the election was 11,141.
Step-by-step explanation:
To determine the number of negative votes in the voting, taking into account that the ratio of votes between positive and negative is 8 to 5 and that there were 6,856 positive votes, it is necessary to perform the following calculation:
6.856 / 8 x 5 = X
857 x 5 = X
4.285 = X
Therefore, there were 4,285 negative votes in the election. So, since 4,285 + 6,856 equals 11,141, the total number of votes cast in the election was 11,141.

Find the equivalent expression for (x+7)(x+1)
Answer:
x^2 + 8x + 7
Step-by-step explanation:
We can see this expression as two distributive property expressions:
(x+7)(x+1) = x(x+1) + 7(x+1)
We can then expand and combine like terms:
(x^2 + x) + (7x + 7) = x^2 + 8x + 7
We have our final answer. I hope this helps! :)
What is the slope of the line? *
Answer:
- 1.5
Step-by-step explanation:
I suggest to make a table

2 -3
from 3 to -3, you subtract 6
from -2 to 2, you add 4
so y/x
-6/4 = -1.5
Slope is -1.5
