Answer:
A
Step-by-step explanation:
the domain is all the possible numbers that the x can be, so to find this from the graph you find the x-value of the leftmost point, which is -1 in this case, and the x-value of the rightmost point, which is 3. this means the range of values would be -1 <= x <= 3

What is the missing constant term in the perfect square that starts with x^2+2x?
Answer:
+ 1
Step-by-step explanation:
Given
x² + 2x
Using the method of completing the square
add ( half the coefficient of the x- term)² to x² + 2x
= x² + 2(1)x + 1²
= x² + 2x + 1
= (x + 1)² ← perfect square

Explain or show your reasoning. (Note: 1 kilogram = 2.2 pounds)
Answer:
1.323 pounds I think I'm not too sure thi sorry
Answer:
1.32 pounds

Jamie is x years old. His friend Ana is the same age.
Enter an expression in the box to represent the sum of Jamie's and Ana's ages.
Explanation:
Each person is x years old. Adding those unknown ages gets us x+x = 2x
We can think of it like x being one box, so x+x represents having two boxes which shortens to 2x.
A positive integer squared plus 3 times it’s consecutive integer is equal to 43
Answer:
the integer is 5
Step-by-step explanation:
x^2+3(x+1)=43
x^2+3x+3=43
x^2+3x+(9/4)=43-3+(9/4)
(x+(3/2))^2=42 1/4
x+(3/2)=sqrt(42 1/4)
x+(3/2)=6 1/2
x=(6 1/2)-(3/2)
x=5
check:
5^2+3(6)=43
25+18=43
43=43
Answer:
5
Step-by-step explanation:
let positive integer be x
x² + 3(x+1)=43
x²+3x+3-43=0
x² + 3x - 40 = 0
x² + 8x - 5x - 40 = 0
x(x+8) - 5(x+8)=0
(x-5)(x+8)=0
x-5=0 or x+8=0
x=5. or x=-8
but the question says positive integer,
therefore, x=5
If the Ending Inventory increases and everything else remains the same, what happens to the Food Cost?
An increase in the ending inventory will cause the cost of food sold at the end of the year to appear lower that it really is.
The cost of goods ( example, food) is directly affected by the amount of inventory at the end of an account period.
If the ending Inventory increases and everything else remains the same, the cost of goods sold is calculated as follows;
cost of food sold = Benning inventory + purchases - ending inventory
From the equation above, an increase in the ending inventory will cause the cost of food sold at the end of the year to appear lower that it really is.

Write the following as a mathematical sentence. Use the letter n as your variable.
Seven less than a number is two.
Answer:
n-7=2
Step-by-step explanation:
We can start with one side, which is: seven less than a number
Since the number is n, seven less than it is n-7
The other side 2, as we can see after the word is
The equation, therefore, is
n-7=2

Answer:
c(1) = -15
c(n) = c(n - 1) + 4
Step-by-step explanation:
Given arithmetic sequence is,
-15, -11, -7, -3...........
Common difference between each successive and previous term is,
d = -11 - (-15)
= -11 + 15
= 4
Since recursive formula of the arithmetic sequence is represented by,
a₁ = First term of the sequence
a(n) = a(n - 1) + d
where a(n) is the nth term and a(n-1) is the previous term of the nth term.
Form the given sequence,
c₁ = -15
c(n) = c(n - 1) + 4

Ali had 5/7 of a spool of yarn. He used 5/6 of his yarn for a project. What fraction of the spool was used for the project? Write your answer in simplest form.
- Due 11:59 today
- Will mark brainliest
Answer:
Step-by-step explanation:
We have no idea what time zone you are in so hope this gets there soon enough.
Do you mean "What fraction of a FULL spool of yarn did he use?" because he used 5/6 of the spool he had.
IF SO
Then
(5/7)(5/6) = 25/42
That's just under 60% of a full spool would be used to complete the same project again.

At a school game, student tickets were 50 cents each and adult tickets were $1 each. If the total receipts from 900 tickets were $500, how many tickets of each kind were sold?
Answer:
Step-by-step explanation:
A(1.00) + S(0.50) = 500
A + S = 900
S = 900 - A
A(1.00) + (900 - A)(0.50) = 500
A + 450 - 0.5A = 500
0.5A = 50
A = 100 adults
S = 900 - 100
S = 800 students
No. of students tickets sold is 800 and no. of adult tickets sold is 100.
What is linear equation in two variable ?A linear equation has highest degree of 1 and it contains two variables generally x and y.
According to the given question At a school game, student tickets were 50 cents each and adult tickets were $1 each. If the total receipts from 900 tickets were $500.
Assuming no. of students to be x and no. of adults to be y.
∴ x + y = 900...(i)
And
0.5x + y = 500...(ii)
Subtracting eqn (i) and (ii) we get
0.5x = 400
x = 800.
So, 800 + y = 900
y = 100.
Therefore how many tickets are sold is same as the no. of students and adults which are 800 and 100 respectively.

Charles wants to buy an anime book that is on sale for $14.99. Her sister kyra wants to buy a novel book for $17.99. Both of them has to pay a 7% tax. Kyra has a coupon for 15% discount. Whats the difference between the amount that each siblings has to pay?
Answer:
The difference between their total amounts is .34 cents
also it didnt look like i was supposed to count a discount for charles so i didnt :)
Step-by-step explanation:
Charles14.99 times .07 = 1.04
14.99 + 1.04 = 16.03
Kyra17.99 times .15 = 2.69
17.99 -2.69 = 15.30
15.30 times .7 = 1.07
15.30 + 1.07 = 16.37
16.37 - 16.03 = .34

Solve the following system of equations:
Answer:
The correct answer is option B: (-1, -1).
Step-by-step explanation:
The easiest way to solve this system is using elimination, or by adding the two equations together. We don't have to modify the equations at all, since the x's will already cancel out as written.
Upon addition, we get:
9y = -9
If we solve the equation by dividing both sides by 9, we get:
y = -1
To find the x value, we can substitute this value back into either of our original equations.
6x + 4y = -10
6x - 4 = -10
To solve for x, we should isolate the variable, or get it alone on one side of the equation.
6x = -6
x = -1
Therefore, the solution to the system of equations is x = -1 and y = -1, or (-1, -1), which is option B.
