Answer:
A function is defined as an operation on a number, which gives only one output for every input
while graphing a function, the x-ordinate denotes the input and the y-ordinate denotes the output of the function
Now, lets look at the graph
for the input value '4' , we notice that there are 2 possible outputs. The output can be either 2.5 or -2.5
Since there are multiple outputs for almost every input, this graph cannot denote a function since a function gives only one output

Alex has a job transporting furniture by truck. His truck is filled with tables that weigh 250 pounds each
and chairs that weigh 20 pounds each. There is a combined total of 300 tables and chairs in his truck.
Let x be the number of tables in his truck. Write an expression for the combined total weight (in
pounds) of the tables and chairs in his truck.
Choose one. 4 points
Total weight in pounds = 230.3 + 50
O
Total weight in pounds = -230.2 + 550
O
Total weight in pounds = -2302 + 75,000
O
Total weight in pounds = 2302 + 6000
Total weight in pounds = 230x + 75,000
Total weight in pounds = -230x + 50
O O
Total weight in pounds = -230x + 6000
Answers
Using a system of equations, it is found that the expression for the combined total weight is given by:
Weight = 250x + 20(300 - x).
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: Number of tables in the truck.Variable y: Number of chairs in the truck.There is a combined total of 300 tables and chairs in his truck, hence:
x + y = 300 -> y = 300 - x
His truck is filled with tables that weigh 250 pounds each and chairs that weigh 20 pounds each, hence the total weight is:
Weight = 250x + 20(300 - x).

Compute using long division: 342 ÷ 23
Answers
Start by setting it up with the divisor 23 on the left side and the dividend 342 on the right side like this:
2 3 ⟌ 3 4 2
Step 2:
The divisor (23) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:
0
2 3 ⟌ 3 4 2
Step 3:
Multiply the divisor by the result in the previous step (23 x 0 = 0) and write that answer below the dividend.
0
2 3 ⟌ 3 4 2
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.
0
2 3 ⟌ 3 4 2
- 0
3
Step 5:
Move down the 2nd digit of the dividend (4) like this:
0
2 3 ⟌ 3 4 2
- 0
3 4
Step 6:
The divisor (23) goes into the bottom number (34), 1 time(s). Therefore, put 1 on top:
0 1
2 3 ⟌ 3 4 2
- 0
3 4
Step 7:
Multiply the divisor by the result in the previous step (23 x 1 = 23) and write that answer at the bottom:
0 1
2 3 ⟌ 3 4 2
- 0
3 4
2 3
Step 8:
Subtract the result in the previous step from the number written above it. (34 - 23 = 11) and write the answer at the bottom.
0 1
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1
Step 9:
Move down the last digit of the dividend (2) like this:
0 1
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1 2
Step 10:
The divisor (23) goes into the bottom number (112), 4 time(s). Therefore put 4 on top:
0 1 4
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1 2
Step 11:
Multiply the divisor by the result in the previous step (23 x 4 = 92) and write the answer at the bottom:
0 1 4
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1 2
9 2
Step 12:
Subtract the result in the previous step from the number written above it. (112 - 92 = 20) and write the answer at the bottom.
0 1 4
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1 2
- 9 2
2 0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 342 divided by 23 calculated using Long Division is:
14
The quotient after division is 322 and the remainder is 20.
What is long division?Long division is the mathematical method for dividing large numbers into smaller groups or parts.
Given that, 342 ÷ 23,
When we will divide 342 by 23, we will get,
The quotient 322 and the remainder is 20.
Hence, the quotient after division is 322 and the remainder is 20.

The height of a parallelogram is 5 feet The base is 7 feet the length is 9 1/2 feet what is the area of the parallelogram
Answers
Answer:
[10 ft.]
Step-by-step explanation:
It's being given that there is a paralleolgram.
Let the length of its base is x ft.
Therefore, length of height = (x+6) ft.
Also, area of paralleolgram = 160 sq.
ft.
Now, we know that,
Area of paralleolgram = base x height
Therefore, we will get,
=> x(x+6) = 160
=> x² + 6x - 160 = 0
=> x² + 16x - 10x - 160 = 0
=> x(x+16) - 10(x+16)=0
=> (x+16) (x - 10) = 0
=> x +16=0 or X- - 10-0
=> x=-16
or
X = 10
But, we know that, length can't ever be negative.
Therefore, x = 10
Hence, length of base = 10 ft.

You should get X^2+2x-4x-8
And then add the like terms.
X^2-2x-8
And use this formula to find the vertex.
X=b/2a
plug in the values
X=-2/2(1)
you should get x=1

C, G, and D are collinear. E, G, and F are also collinear. The two lines
intersect at point G. Line EF bisects line CD. Find EG: if CG=5x-1, GD=7x-
13, EF=6x-4, and GF=13.
Answers
Answer:
EG is 19 units
Step-by-step explanation:
Let us solve the question
∵ Lines CD and EF intersected at point G
∴ CD = CG + GD
∴ EF = EG + GF
∵ Line EF bisects line CD
→ That means G is the midpoint of CD
∴ CG = GD
∵ CG = 5x -1
∵ GD = 7x - 13
→ Equate them to find x
∴ 7x - 13 = 5x -1
→ Add 13 to both sides
∴ 7x -13 + 13 = 5x - 1 + 13
∴ 7x = 5x + 12
→ Subtract 5x from both sides
∴ 7x - 5x = 5x - 5x + 12
∴ 2x = 12
→ Divide both sides by 2
∴ [tex]\frac{2x}{2}=\frac{12}{2}[/tex]
∴ x = 6
∵ EF = 6x - 4
→ Substitute x by 6 to find its length
∴ EF = 6(6) - 4 = 36 - 4
∴ EF = 32
∵ EF = EG + GF
∵ GF = 13
∴ 32 = EG + 13
→ Subtract 13 from both sides
∵ 32 - 13 = EG + 13 - 13
∴ 19 = EG
∴ EG = 19 units

12X + 48y = 192
Answers
Answer:
x=4
y=3
Step-by-step explanation:
12X + 16y = 96--(1)
12X + 48y = 192---(2)
(2)-(1),
12x + 48y - (12x+ 16y)= 192- 96
12x + 48y - 12x - 16y = 96
32y = 96
y= 96÷32
y =3
substituting y=3 in (1),
12x +(16×3) = 96
12x + 48 = 96
12x = 96-48
12x = 48
x= 48÷12
x= 4

Maura added 5/8 of a cup of walnuts to a batch of trail mix. Later, she added 3/4 of a cup of almonds. How many cups of nuts did Maura put in the trail mix in all? Write your answer as a fraction or as a whole or mixed number. cups
Answers
Answer:
1 3/8 cups
Step-by-step explanation:
the equation is 5/8 + 3/4
to figure it out we need the same denominator, we'll be choosing 8
3 (x2)/ 4 (x2) = 6/8
you would have to multiply 2 both on the top and bottem
then you would have to add
5/8 + 6/8 = 11/8
then make that into a whole fraction
11/8 = 1 3/8
