Answer:
(D) The bottom graph, and (A) The top table.
Step-by-step explanation:
The easiest way to pick out the wrong answers is simply through substitution. Substitute the input into the x part of the equation that is given and if it doesn't match up with y everytime, then it is incorrect.
From table A (top table), the input x can be substituted into y = x + 2 which will come out as the output so it is correct.
For table A:
x = -3 → y = x + 2 → y = (-3) + 2 → y = -1 = -1
x = -2 → y = x + 2 → y = (-2) + 2 → y = 0 = 0
x = -1 → y = x + 2 → y = (-1) + 2 → y = 1 = 1
x = 0 → y = x + 2 → y = (0) + 2 → y = 2 = 2
x = 1 → y = x + 2 → y = (1) + 2 → y = 3 = 3
Since the table matches up with the inputs and outputs of the table, it is a correct answer.
For table B:
x = 3 → y = x + 2 → y = (3) + 2 → y = 5 = 5
x = 4 → y = x + 2 → y = (4) + 2 → y = 6 ≠ 7
x = 5 → y = x + 2 → y = (5) + 2 → y = 7 ≠ 9
x = 6 → y = x + 2 → y = (6) + 2 → y = 8 ≠ 11
x = 7 → y = x + 2 → y = (7) + 2 → y = 9 ≠ 13
5 out of the 6 y values of the table do not match the equation, so table B must be incorrect.
Graph C:
Notice how you can see the line cross the x, and y axis. When the line crosses the x axis, it is an x intercept which means y is 0. When the line crosses the y axis, it is a y intercept which means x is 0.
Since the line crosses the y axis at 2, this means that an x of 0 must lead to a y of 2 which it does.
x = 0 → y = x + 2 → y = (0) + 2 → y = 2 = 2.
But the x intercept doesn't match up as shown here.
y = 0 → y = x + 2 → (0) = x + 2 →
0 – 2 = x + 2 – 2 → -2 = x → x = -2 ≠ -1
When graphing the line y = x + 2, it's x intercept should be (-2,0). While on this graph, it's (-1,0). This means that this graph is incorrect which leads to D being another correct answer.
✓ Table A: y = x + 2
× Table B: y = 2x – 1
× Graph C: y = 2x + 2
✓ Graph D: y = x + 2

Answers
Answer:
y = 7/4x
Step-by-step explanation:
All you have to do is find the slope by using the formula change in y divided by change in x of the two points. You can see that y goes up by 14 when x goes up by 8. This means that the slope is 14/8, or 7/4.
The equation would then be y = 7/4x
The four walls and the ceiling of a cubical room need to be painted. If the height of the room is 4 m , and painting costs ₹ 20/m2 20 / m 2 , what is the total cost of painting the room?
Answers
Answer:
₹ 1920
Step-by-step explanation:
Since the room is cubical in nature, we will find the total surface area of the room
Total surface area of the cubical room = 6L²
L is the length of one side of the room
Given
L = 4m
Total surface area of the cubical room = 6(4)²
Total surface area of the cubical room = 6×16
Total surface area of the cubical room = 96m²
If the painting costs ₹ 20/m², this means;
₹ 20 = 1m²
For the total room:
x = 96m²
Divide both expressions
20/x = 1/96
x = 20×96
x = 1920
Hence the total cost of painting the room ₹ 1920

Base = 147cm2
Volume= 1323
What is the height ?
Answers
The height of the rectangular prism will be 9 cm.
What is the volume of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H.
Then the volume of the prism is given as
V = L x W x H
We know that the product of the length and width will be known as the base area.
Then the volume of the rectangular prism will be
V = A x H
Base area = 147 cm²
Volume = 1323 cm³
Then the height of the rectangular prism will be
1323 = 147H
H = 9 cm
The height of the rectangular prism will be 9 cm.
The complete question is attached below.

At a gas station, all chips are marked down 10%. A customer brings a bag of chips with a regular price of $2.19 to the register. After the 7% sales tax on the final price, how much does the customer pay for the bag of chips ?
Answers
Answer: $2.11
Step-by-step explanation:
A customer brings a bag of chips with a regular price of $2.19 to the register which is marked down 10% the price to pay will be:
= $2.19 - (10% × $2.19)
= $2.19 - $0.219
= $1.971
After a 7% sales tax on the final price, the amount paid by the customer will be:
= $1.971 + (7% × $1.971)
= $1.971 + $0.13797
= $2.11

I need to find the missing angle thank you
Answers
Answer:
The missing angles measure is 70 degrees
Step-by-step explanation:
First we must complete the left triangles last measure:
60+65+x=180
x=55
Then we have to make all of those three middle angles equal 180:
55+50+y=180
105+y=180
y=75
Now we add 75 to 35 to the missing angle to get 180:
75+35+z=180
110+z=180
z=70
The missing angles measure is 70 degrees
Some eighth-grade students want to raise at least $300 for a field trip by selling popcorn and fruit bars. The chart below shows the amount of profit they will make on each sale. If they sell exactly 500 fruit bars, how many boxes of popcorn will they need to sell to make a total of $300? 30 cents fruit bars. 60 cents box of popcorn
Answers
popcorn = 60 cts
fruitbars = 30 cts
.
they sold 500 fruit bars = 500 x 0.30 = 150
.
(300 - 150)/0.6 = 150/0.6 = 250 this is how many popcorn they need to sell
The total number of popcorn boxes is given by the equation
A = 250 boxes
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of boxes of popcorn be A
Now , the equation will be
Let the cost of one fruit bar = $ 0.30
Let the cost of one popcorn box = $ 0.60
The amount to be raised = $ 300
The number of fruit bars sold = 500
So , the cost of 500 fruit bars = 500 x cost of one fruit bar
Substituting the values in the equation , we get
The cost of 500 fruit bars = 500 x 0.30
The cost of 500 fruit bars = $ 150
Now , the remaining amount to be raised = 300 - 150
The remaining amount to be raised = $ 150
The number of boxes of popcorn A = remaining amount to be raised / cost of one popcorn box
Substituting the values in the equation , we get
The number of boxes of popcorn A = 150 / 0.60
The number of boxes of popcorn A = 250 boxes
Therefore , the value of A is 250 boxes
Hence , the number of boxes is 250

Angles and Lines
The figure attached below has been completed with the angle y to support the calculations to come.
The sum of the interior angles of a rectangle is 180°. Applying on triangle PQR:
30 + 4x + 2 + y = 180
Simplifying:
32 + 4x + y = 180
Solving for y:
y = 180 - 32 - 4x
y = 148 - 4x
Angles y and 8 + 6x are a linear pair, i.e. their sum is 180°, thus:
y + 8 + 6x = 180
Substituting y from the equation above:
148 - 4x + 8 + 6x = 180
Simplifying:
156 + 2x = 180
Dividing by 2:
78 + x = 90
Subtracting 78:
x = 90 - 78
x = 12
