Answer:C. f(x)=7+5x
Step-by-step explanation:
12=5(1)+n
12=5+b
-b+12=5
-b=5-12
5-12=7
-b=7
f(x)=7+5x
I know this because I just answered this question and got it right
The equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The table is given,
From the data given in the table:
12 = 5(1)+n
12 = 5+b
b = 7
The function would be:
f(x) = 7 + 5x
Thus, the equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.

Tax rates are: no tax on the first £11000 of earnings earnings in excess of £11000 and up to £43000 taxed at a rate of 20% earnings in excess of £43000 and up to £150000 taxed at a rate of 40% Carys earned £45600 before tax how much tax did she pay in total?
Answer:
She paid tax of £18240
Step-by-step explanation:
We are told that Carys earned £45600 before tax.
Now, from the question, the tax rate that applies is 40%. This is because she earned £45600 and we are told that earnings in excess of £43000 and up to £150000 taxed at a rate of 40%.
Thus;
Tax payable = 40% × 45600
Tax payable = £18240

B. Alex puts 1/4 1of his money in savings and uses 1/( 2) of the remaining money to pay back her sister. If she has GH¢15 left, how much did she have at first?
Answer:
GH¢60
Step-by-step explanation:
Alex puts 1/4 1of his money in savings and uses 1/( 2) of the remaining money to pay back her sister. If she has GH¢15 left, how much did she have at first?
Let the Total amount of Alex money = 1
We are told that she has GH¢15 left,
Hence, we find the fraction of the money she has left
1 - (1/4 + 1/2)
1 - 3/4
= 1/4
The fraction of the amount she left = 1/4
Let x represent the total amount of money that Alex had
1/4 × x = GH¢15
x / 4 = GH¢15
Cross Multiply
x = 4 × GH¢15
x = GH¢60
Therefore, Alex had GH¢60 at first

Answer: x = 10
Step-by-step explanation:
first Add 20 to both sides.
4x = x + 10 + 20
Then Simplify x + 10 + 20 to x + 30
4x = x + 30
Then u subtract x from both sides
4x - x = 30
Simplify 4x - x to 3x
3x = 30
Then u divide both sides by three
x = 30/3
Then u last simplify 30/3 to 10
x = 10
Answer:
x = 10
Step-by-step explanation:
first Add 20 to both sides.
4x = x + 10 + 20
Then Simplify x + 10 + 20 to x + 30
4x = x + 30
Then you subtract x from both sides
4x - x = 30
Simplify 4x - x to 3x
3x = 30
Then you divide both sides by three
x = 30/3
Then you last simplify 30/3 to 10
x = 10

Step-by-step explanation:
Theoretically, the standard error of the mean decreases as the sample size increases measures the variability of the sample mean from sample to sample is never larger than the standard deviation of the population All of the Above
Answer: All of the above
Step-by-step explanation:
The formula for the standard error of the mean is:
σM =σ/√N
where,
σM = standard error of the mean
σ = standard deviation of sample
√N = square of sample size
As the sample size of a population rises, it should be noted that the standard error of the mean will decrease. This is due to the fact that when there's an increase in sample size, there'll be cluster of the sample mean around the population mean.
Also, the the standard error of the mean measures the variability of the sample mean from sample to sample and is never larger than the standard deviation of the population.
Therefore, the answer will be "all or the above".

An insurance company only pays for full replacement if a driver is in a
wreck and is traveling a speed not deemed to be reckless. A speed of 80
mph or greater is considered reckless. Mallory has an accident and has
filed an insurance claim. The insurance uses a standard constant of
proportionality of .05 and she has a stopping distance of 245 feet. Will her
insurance provide a full replacement of her car? Explain why or why not
and show all work.
Answer:
70 mph, Yes the insurance company Will provide a full replacement for her car.
Step-by-step explanation:
To get the equation lets use direct variation, and K for the constant, S for the speed, and D for the stopping distance. d=ks^2, find s, or the speed, which will get the equation s=√d/k. The speed s, is equal to the square root of the stopping distance divided by the constant. Next, lets plug in the numbers s=√245/.05. Then, we find the square root of each number, √245 = ~15.652, and √.05 ~.2236 s=15.652/.2236 then divide, which will equal s=70. 70<80, so the insurance company will provide a full replacement for her car.
I hope this helps!
which step is wrong pls help
Answer:
the second step and third step
Step-by-step explanation:
in the second step, you are supposed to move 5x to the left side
in the process of this, 5x should turn negative, and you should be subtracting it from 7x, not adding it.
so the +5x should be -5x
in the third step you should divide, but when you divide 6 by 12, you should get 0.5, not 2.

The length of a rectangle is twice its width. The perimeter is 60 ft Find its area.
a) A=200 ft²
b) A= 10 ft²
c) A= 100 ft ²
Answer:
A=200 ft²
Step-by-step explanation:
let the Length be L and the Width be W
We know that Perimeter = Length + Length + Width + Width
or,
Perimeter = 2(L + W)
given that Perimeter = 60 ft,
60 = 2(L+W) (divide both sides by 2)
60/2 = (L+W)
L + W = 30 ---------------------eq 1
we are further given that the length is twice the width, or,
L = 2W ---------------------- eq 2
substituting eq2 into eq 1,
L + W = 30
(2W) + W = 30
3W = 30
W = 10 (substitute this into eq 2)
L = 2W
L = 2(10)
L = 20
Area = Length x Width
= 20 x 10
= 200 ft²

Jadiel wants to take his buddies out for pizza. Each medium
pepperoni pizza costs $10, and he has only $23 in his pocket. How
much money would he have to borrow to order three medium
pepperoni pizzas?
Answer:
7$
Step-by-step explanation:
1) 3x10=30 so 30 is how much money he needs
2)30-23=7 so 7 is how much he needs to borrow
Answer:
$7
Step-by-step explanation:
The reason is because three medium pepperoni pizzas cost $30, because you have to multiply $10x3 since each pizza cost $10. He already has $23 dollars in his pocket. You have to subtract his total value which is $23 from $30 to get $7.

Dorian and Jack decided to go bowling. They each need to rent shoes and 1 lane, and Jack is a member.If Jack pays for both of them with $20, what change should he receive?
Answer:
$6.60
Step-by-step explanation:
This is an incomplete question. I have however searched for the concluding parts and same attached as seen below.
First, we need to calculate the costs for both shoes rented by Dorian and Jack.
Member's cost for each shoe rentage is $2.95 , and since both rents the shoe at same cost, therefore,
Cost = $2.95 + $2.95 + $7.50
Cost = $13.40
To get the balance that Jack should receive, we will simply deduct the cost from the initial $20 member cost, hence;
Balance = $20 - $13.40
Balance = $6.60.
Therefore, the change that should be received by Jack is $6.60
The lengths of the sides of a quadrilateral are 4 consecutive even integers. The perimeter of the quadrilateral is 36 inches. What is the length of the longest side?
Answer:
Length of longest side is 10.5 inches
Step-by-step explanation:
Let the shortest side of the quadrilateral be x inches
The length of the consecutive sides will be;
x , x + 1 , x + 2 and x + 3 inches
By adding all
together, we get the perimeter of the quadrilateral
so;
x + x + 1 + x + 2 + x + 3 = 36
4x + 6 = 36
4x = 36-6
4x = 30
x = 30/4
x = 7.5 inches
The longest side is x + 3 = 7.5 + 3 = 10.5 inches
