Brian invests £4700 into his bank account.
He receives 5.5% per year compound interest.
How much will Brian have after 3 years?
Answer:
5,548.9861375
Step-by-step explanation:
First year
4700/100×5.5=258.5
So his account will be 4700+285.5=4985.5
Second year
4985.5/100×5.5=274.2025
His account will be 4985.5+274.2025=5,259.7025
Third year
5,259.7025/100×5.5=289.2836375
The total in his account after three years equal to
289.2836375+5259.7025=5,548.9861375

Describe the lines below as parallel, perpendicular,or neither.
3x+6y=42 and y=2x-1
Answer:
They are neither perpendicular nor parallel.
Step-by-step explanation:
Find the gradient of 2x + 6y = 42 by rearranging it in the form y = mx + c:
6y = -2x + 42
y = -(1/3)x + 7
The gradient is the co-efficient of x
Therefore the gradient is -(1/3)
The gradient of y = 2x - 1 is 2.
If they were parallel they would have the same gradient.
If they were perpendicular then the gradient of one would be the negative reciprocal of the other, e.g: if one was 2, the other would be -(1/2).
Neither of these are true, so they are neither perpendicular nor parallel.
The lines 3x+6y=42 and y=2x-1 are perpendicular
Two lines are parallel if they have equal slope
Two lines are perpendicular if the product of their slopes equals -1
The given lines are:
3x+6y=42 and y=2x-1
Rewrite each of the equations in the form y = mx + c
For line 3x + 6y = 42:
[tex]6y = -3x + 42\\\\y=\frac{-3}{6} x+\frac{42}{6}\\\\y=-0.5x+7[/tex]
The slope, m₁ = -0.5
For line y = 2x - 1
The slope, m₂ = 2
Since m₁ ≠ m₂, lines 3x+6y=42 and y=2x-1 are not parallel
m₁ m₂ = -0.5(2)
m₁ m₂ = -1
Since the product of the slopes equals -1, the lines 3x+6y=42 and y=2x-1 are perpendicular

Jon earns $4 for delivering groceries and $2 for each delivery he makes.
How much money will he earn if he delivers to five houses?
Answer:
$14
Step-by-step explanation:
ok so since he is delivering groceries he gets $4.
now when he delivers he get $2 more, so for each house he delivers to he adds $2 to that $4.
so the easiest was to do this is 5x2.
5x2 is 10.
now $10 is how much more he gets on top of the $4, so now we need to add the $4 to the $10.
your answer is $14

2x - 3y --24
x + 6y = 18
Substitution
Answer:
y=12
x=30
Step-by-step explanation:
2x-3y=24 ... 1
x+6y=18 ... 2
2*2:
2x+12y=36...3
3-1:
y=12
x=30
When the following system of equations 2x - 3y = -24 and x + 6y = 18 are solved, the value of x and y is found to be -6 and -4 respectively.
Mathematically, an equation is a statement that asserts the equivalency of two expressions. It consists of two hands, the left-hand side( LHS) and the right-hand side( RHS), separated by an equal sign( =). The LHS and RHS can be numbers, variables, constants, or further complex fine expressions.
Given the system of equations:
2x - 3y = -24 (equation1)
x + 6y = 18 (equation2)
From equation 2,
x = 18 - 6y
Now, substitute this expression for x in equation (1):
2(18 - 6y) - 3y = -24
36 - 12y - 3y = -24
36 - 15y = -24
-15y = -60
y = [tex]\frac{(-60)}{(-15)}[/tex]
y = 4.
Now substitute it back into equation (2) to solve for x:
x + 6(4) = 18
x + 24 = 18
x = 18 - 24
x = -6
Therefore, the solution to the system of equations is x = -6 and y = 4.

Emiliana pays 6% sales tax on a cupcake that costs 3 dollars. How much does the sales tax add to the purchase price? Please tell me how you got the answer. (answer choices: $0.018, $18, $0.18, $3.18)
Answer:
$0.18 sales tax will be added to the purchase price.
Step-by-step explanation:
Given that:
Cost of cupcake = $3
Sales tax applied = 6%
Amount of sales tax = 6% of cost of cupcake
Amount of sales tax = [tex]\frac{6}{100}*3[/tex]
Amount of sales tax = 0.06 * 3 = $0.18
Hence,
$0.18 sales tax will be added to the purchase price.

Please check the attached graph below.
The line graph is representing that a number line:
Going from negative 2 to positive 2 in increments of 1. There are 4 equal spaces between each number.From the graph, it is clear that the point 0 is taken as arbitrary. The left side number units from 0 represent the negative values and the right-sided number units from 0 represent the positive values.
When we move on the right side from the 0, the numbers increase and when you move on the right side from the 0, the number decreases.
Answer:
The number line shows -2 through 2, divided into fourths, with zero in the middle. The numbers increase as you move right and decrease as you move left.

Lennox owns a big apple orchard. She ships her apples to various markets using a fleet of trucks. Every week, each truck goes on 3 trips, and for each trip, Lennox gets 300 dollars. On a single trip, a truck delivers 50 packs, and each pack contains 12 kilograms of apples. Overall, Lennox sells 4500 dollars worth of apples in a week.
How much does Lennox get for a single kilogram of apples?
____________dollars per kilogram
Answer:
$0.50 per kilogram
Step-by-step explanation:
($300/trip)/(50 packs/trip) = $6/pack
($6/pack)/(12 kilograms/pack) = $0.50/kilogram
To be labeled as a jumbo egg, the egg is supposed to weigh 2.5 oz. Mia buys a carton of jumbo eggs and measures one of the eggs as 2.4 oz. What is the percent error? *
Answer: 4.17%
Step-by-step explanation:
Formula for percentage error = [tex]\dfrac{|\text{Estimated weight - Actual weight}|}{\text{Actual weight}}\times100[/tex]
Given: Estimated weight = 2.5 oz
Actual weight = 2.4 oz
Percentage error = [tex]\dfrac{2.5-2.4}{2.4}\times100\%[/tex]
[tex]=\dfrac{0.1}{2.4}\times100\%\\\\=\dfrac{100}{24}\%=4.17\%[/tex]
Hence, the percent error = 4.17%

The function c(x) = 18x -10 represents the cost in dollars. How many tickets can you buy?
Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.
So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 170 dollars.
The solution would still clear your concept though.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]c(x) = 18x -10[/tex]
The slope-intercept form of the line equation
We know that the slope-intercept form of the line equation
y=mx+b
where m is the slope and b is the y-intercept
so
[tex]c(x) = 18x - 10[/tex]
comparing with the slope-intercept form of the line equation
here:
rate of change = 18c(x) or y represents the costand
'x' represents the number of tickets
Assuming the total cost i.e. c(x) = $170
In order to determine the value of x, set c(x) = 170
i.e.
170 = 18x -10
switch sides
18x - 10 = 170
add 10 to both sides
18x - 10 + 10 = 170 + 10
18x = 180
Divide 18 to both sides
18x/18 = 180/18
x = 10
Therefore, if you can buy x = 10 tickets if you pay 170 dollars.

Write the equation, 3x+7=2(3-y) in function form.
Answer:
The function of the equation is f(x) = [tex]-\frac{1}{2}[/tex] [tex]-\frac{3}{2}[/tex] x
Step-by-step explanation:
The function form of the linear equation is f(x) = m x + b, where
m is the slope of the line represents the graph of the functionb is the y-intercept∵ The equation is 3x + 7 = 2(3 - y)
→ Simplify the right side by multiplying the bracket by 2
∵ 3x + 7 = 2(3) - 2(y)
∴ 3x + 7 = 6 - 2y
→ Add 2y for both sides
∵ 2y + 3x + 7 = 6 - 2y + 2y
∴ 2y + 3x + 7 = 6
→ Subtract 7 from both sides
∵ 2y + 3x + 7 - 7 = 6 - 7
∴ 2y + 3x = -1
→ Subtract 3x from both sides
∵ 2y + 3x - 3x = -1 - 3x
∴ 2y = -1 - 3x
→ Divide each term by 2
∴ y = [tex]-\frac{1}{2}[/tex] - [tex]\frac{3}{2}[/tex] x
→ Replace y by f(x)
∴ f(x) = [tex]-\frac{1}{2}[/tex] [tex]-\frac{3}{2}[/tex] x
∴ The function of the equation is f(x) = [tex]-\frac{1}{2}[/tex] [tex]-\frac{3}{2}[/tex] x
Write a function g whose graph represents the indicated transformation of the graph of F. Let g be a translation 4 units down and a horizontal shrink by a factor of of the graph of f(x) = x.
Answer:
g(x) = 6x+4
Step-by-step explanation:
The given function f(x)=x
Let p(x) be an intermediate function after translation of f(x).
So, after the translation 4 unit down, the new function
p(x) = f(x) - 4
p(x) = x-4
Now, there is a horizontal shrink by a factor of 6, so the required function g(x) is
g(x) = p(6x) [here 6 is the horizontal shrink factor]
g(x) = 6x-4
Hence, the required function is g(x) = 6x+4
