If I were to make a quick guess I think this is the line y=4X
Answer:
its linear (i know how to draw the graph but i cant show you here, just make umm an x axis and y axis from 1 to 30 ) (also i feel like theres another way to know if its linear but this is how i would do it!)
Step-by-step explanation:
to see if its linear ummm we first have to find the slope, the equation for the slope is
y2 - y1 / x2 - x1
lets use the points (2, 8) and (3, 12)
12 - 8/ 3 -2
4 / 1
4
y = 4x + b
now to find the y-intercept lets input a point we did not use yet
(5, 20)
20 = 4(5) + b
20 = 20 + b
b = 0
y = 4x
now we check if its linear with the points (6, 24) and (3.5, 14) sooo
24 = 4(6) ?
24 = 24
14 = 4(3.5) ?
14 = 14
so yes it is a linear graph

Loss=Rs 80
Loss%=4%
Step-by-step explanation:
Cost price of trousers for Ujeli=Rs2000
Marked price for trousers =Rs 2400
Reduction of MP(take it as discounted) =20%
Selling price=MP-20%of MP=2400 - 20/100 * 2400 = 2400 - 480 = Rs 1920
Loss amount =CP - SP = 2000 - 1920 = Rs 80
Loss% =loss amt/CP *100 =80 / 2000 *100 =4%

Answers
Assuming the entire quadrilateral is a parallelogram, we can say that using the property of diagonals;
The diagonals of a parallelogram bisect each other, meaning that RQ is divided into two equal parts.
If half of RQ is 9.3 then,
RQ=2×9.3=18.6 in
That's your answer RQ=18.6 in

Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form.
Answers
Answer:
y=2x+1
Step-by-step explanation:
The point-slope form is (y-y1)=m(x-x1), with x1 and y1 being the coordinates from ordered pair, and m being the slope. You can plug all of those values into the original equation:
(y-y1)=m(x-x1)
y-3=2(x-1)
y-3=2x-2
y=2x+1
Suppose the cost of mailing a letter is $0.23 per ounce plus $0.14. The equation
gives the total cost c of mailing a letter is c = 0.23w + 0.14, where w is the weig
ounces. What is the cost of mailing a 6-ounce letter?
Answers
Answer:
$2.22
Step-by-step explanation:
First, we know that the cost of one mailing letter is $0.23 per once, plus $0.14.
Our formula is: c = 0.23w + 0.14
Let's rewrite our variables to the way it's suppsed to be.
C = cost
W = weight ounces.
Now, we have to add 0.23 plus 0.14 to get our cost.
That equals 0.37.
Now that we know that our cost for one letter is 0.37, we have to multiply
it by 6, because we are trying to figure out the cost of mailing a 6 ounce letter.
0.37 × 6 = 2.22
In conclusion, the cost of mailing a 6 ounce letter is $2.22
Mark invested $500 for 3 years at 6% per annum. The simple interest Mark received was
Answers
Answer:
$90
Step-by-step explanation:
We use the simple interest formula,
I = Prt
where
I = interest
P = principal amount = $500
r = interest rate = 6% = 0.06
t = time = 3 years
I = Prt
I = $500 × 0.06 × 3
I = $90

You want to identify the expressions equivalent to 11x -4x +6x and 3(1 +9y).
SimplifyWe can identify the equivalent expressions by putting them all in their simplest form. This means using the distributive property to eliminate parentheses, and combining like terms.
(a) 11x -4x +6xThe simplified version of the given expression is ...
(11 -4 +6)x = 13x
The other expressions simplify to ...
7x +6x = (7+6)x = 13x . . . equivalent

The employees of a hardware store ordered lunch from a local delicatessen. The lunch consisted of 4 turkey sandwiches and 7 orders of french fries, for a total cost of $38.30. The next day, the employees ordered 5 turkey sandwiches and 5 orders of french fries totaling $40.75. What does the delicatessen charge for a turkey sandwich? What is the charge for an order of french fries?
Answers
Answer:
Charges of Turkey is $6.25
Charges of French Fries is $1.90
Step-by-step explanation:
Given
Represent Turkeys with T and French Fries with F;
[tex]4T + 7F = 38.3[/tex]
[tex]5T + 5F = 40.75[/tex]
Required
Determine the values of T and F
[tex]5T + 5F = 40.75[/tex]
Divide through by 5
[tex]T + F = 8.15[/tex]
Make F the subject
[tex]F = 8.15 - T[/tex]
Substitute 8.15 - T for F in the first equation
[tex]4T + 7F = 38.3[/tex]
[tex]4T + 7(8.15 - T) = 38.30[/tex]
[tex]4T + 57.05 - 7T = 38.30[/tex]
Collect Like Terms
[tex]4T - 7T = 38.30 - 57.05[/tex]
[tex]-3T = -18.75[/tex]
Solve for T
[tex]T = -18.75/-3[/tex]
[tex]T = 6.25[/tex]
Recall that:
[tex]F = 8.15 - T[/tex]
[tex]F = 8.15 - 6.25[/tex]
[tex]F = 1.90[/tex]
Katelyn sells cars at a used car dealer on commission. The car lot pays a 18% commission when the profit on a car is under $400, 22% when the profit is at least $400 and less than $1,000, and 24% when the profit is $1,000 or more. How much will she receive if she sold $800 in profits?
Answers
Answer:
She will receive 22% commission

The height h (in feet) of an object dropped from a window after x seconds can be modeled by h(x)=−16x2+64 . The object is dropped a second time so that it hits the ground 1.5 seconds sooner. Write a function g that models the path of the object the second time it is dropped.
Answers
Answer:
g(x) = - 16x² + 4
Step-by-step explanation:
Given the model:
First drop:
h(x) = - 16x² + 64
Second drop hits the ground 1.5 seconds sooner
Function g(x) to model the second drop:
-16t² + V0t + h0
h(x) = - 16x² + 64
0 = - 16x² + 64
16x² = 64
x² = 64/16
x = 2
1.5 seconds sooner :
X = 2 - 1. 5
x = 0.5
0 = - 16(0.5)² + 0 + h0
0 = - 4 + h0
h0 = 4
Hence,
g(x) = - 16x² + 4
Carlos was having a home built. The blueprints are shown below. The scale for the blueprints to the actual house is 2 inches to 7 feet.
Part A What is the actual width of the entire building
Part B What is the length of the entire building
Answers
Part A: 28 ft
Explanation: you have to change 8 in to ft using the scale 2 in to 7 ft.
Part B: 84 ft
Explanation: you have to change 24 in to ft using the scale
The actual width of the entire building is 28 feet and the length of the entire building is 84 feet.
Given that, the scale for the blueprints to the actual house is 2 inches to 7 feet.
What is the scale factor?The scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Now, width = 8 inches in feet is 4 × 7 =28 feet
Length = 14+10 =24 inches in feet is 12 × 7 = 84 feet
Therefore, the actual width of the entire building is 28 feet and the length of the entire building is 84 feet.

Step-by-step explanation:
complementary angles is when their sum = 90 so
30 + 2x + 10 = 90
2x = 90 - 40
2x = 50
X = 25
Answer:
x = 25
Step-by-step explanation:
1. Due to the fact that Angle F and angle G are complementary, 2x + 10 + 30 = 90.
2. Solve this equation: 2x + 10 + 30 = 90
Add 10 and 30
2x + 10 + 30 = 90
2x + 40 = 90
3. Subtract 40 from 90
2x + 40 = 90
2x = 90 - 40
2x = 50
4. Divide 2 from 50
x = 50/2
x = 25
