Answer:
(-3,-8)
Step-by-step explanation:
MN:Np=3:4 Let m:n=3:4
Use the formula
xN=(xM*n+xP*m)/(m+n)
yN=(yM*n+yP*m)/ (m+n)
xN= ((-12)*4+9*3)/ (4+3)=-3.
yN=((-5)*4+(-12)*3)/(4+3)=-8.
Given directed line segment JL below, find the coordinates of K such
that the ratio of JK to JL is 7:8. Plot point K.
The coordinate of JK is (-1.7, -0.3)
The coordinate of the points that divides the line segment in the given ratio is calculated as:
[tex](x, y) = (\frac{ax_1 +bx_2}{a+b} , \frac{ay_1 +by_2}{a + b} )[/tex]
where;
a:b = 7:8
From the image;
(x₁, y₁) = (-6, 5) and,
(x₂, y₂) = (2, -5)
Substitute the given points in the equation above to calculate the coordinates of JK.
[tex](x, y) = (\frac{7(-6)+8(2)}{7+8} , \frac{7(5) +8(-5)}{7+8} )\\\\(x, y) = (\frac{-26}{15} , \frac{-5}{15} )\\\\(x,y) = (-1.7, -0.3)[/tex]
Thus, the coordinate of JK = (-1.7, -0.3)

A machine costing $56,745 with a 7-year life and $51,208 depreciable cost was purchased January 1. Compute the yearly depreciation expense using straight-line depreciation. Round your answer to the nearest whole dollar.
How much is per year?
Answer:
$7315
Step-by-step explanation:
To find the depreciation expense, we use this formula:
Depreciable cost ÷ useful life time
Depreciated cost = $51,208
Life time = 7 years
51,208 ÷ 7 = 7315.42857
This means that $51,208 were lost over the 7 years, meaning $7315 were lost every year.

Answer:
A is the answer
Answer:
the first one is the answer y = (x-2)^2 + 1
Step-by-step explanation:
The vertex form of a quadratic function is y = a(x – h)^2 + k, where a, h, and k are constants. h and k are vertex.
vertex is (2,1) which is (h,k)
passes through (0,5)
Equation is y = a( x - 2)^2 + 1 . now substituting (0,5) in for x and f(x),
5 = a ( 0 - 2) ^2 + 1 and solve for a.....
5 = 4a + 1
5-1 = 4a
4a = 4.......... a = 1
equation becomes y = 1(x-2)^2 + 1 or y= (x-2)^2 + 1

A quantity of food will last 8 people for 18 days. How long will the food last 2 people?
Answer: 72 days
Step-by-step explanation:
STEP ONE: Find the total amount of food
Total days = 18 days
Total people = 8 people
Total food = days × people
Total food = 18 × 8
Total food = 144
STEP TWO: Find the days that would last for 2 people
Total people = 2 people
Total food = 144 units
Total days = food ÷ people

John has an account balance of $20. He receives his weekly paycheck
for work at his part-time job in the amount of $110. He can't find
a bike he wants, so he buys some comic books for $40. Then John
finds his dream bike priced as shown. If he buys the bike now, what
will his account balance be?
Step-by-step explanation:
Accounts balance=$20
Part time job salary=$110
Total balance
\begin{gathered}\\ \sf\longmapsto 110+20=130\$\end{gathered}
⟼110+20=130$
Now
Price of comics=$40
Price left for bike
\begin{gathered}\\ \sf\longmapsto 130-40=90\$\end{gathered}
⟼130−40=90$
After buying the dream bike, John's account balance will be -$110.
Let's calculate John's account balance after each transaction step by step:
1. Initial balance: $20
2. Weekly paycheck: +$110
Account balance = $20 + $110 = $130
3. Buys comic books: -$40
Account balance = $130 - $40 = $90
4. Buys dream bike: -$200
Account balance = $90 - $200 = -$110
After buying the dream bike, John's account balance will be -$110. This means he will have a negative balance of $110, indicating that he owes the bank or whoever manages the account. It's important to be cautious with negative balances as they can result in overdraft fees or other penalties depending on the account type and the bank's policies.

19. Rashmika bought a second hand T.V. for Rs. 6,000 and she spent Rs. 1500 on its repair. She sold it for Rs. 5,500. Find her profit or loss.
Cost of TV= Rs. 6000
Money spent on repair= Rs. 1500
So, money left after repair= 6000-1500= Rs. 4500
She sold it for Rs. 5,500
Therefore, Profit= 5500-4500= Rs. 1000
So profit= Rs. 1000
Answer:
2,000 loss
Step-by-step explanation:
Total Revenue - Total Expenses = Profit
Total expenses = 6,000(Original cost) + 1500(repairs) = 7,500
Total revenue = selling price = 5,500
Therefore the Profit or Loss(negative number) =
5,500 - 7,500 = -2000 or 2,000 loss

2. A laptop usually sells for £1320 (including VAT). A store is advertising a discount of 15%
if it is purchased on a Sunday and a further 10% student discount. What is the price that a
student should pay (including VAT) for a Sunday purchase?
Answer:
£1009.8
Step-by-step explanation:
1) 1320/100*15= 13.2*15= 198- Sunday discount,
2) 1320-198=1122- The value with Sunday discount,
3) 1122/100*10= 112.2 - the student's discount,
4) 1122-112.2= 1009.8
The student paid £990 for the purchase of the laptop.
An equation is used to show the relationship between two or more numbers and variables.
The student purchase the laptop on a Sunday, hence:
Total discount = 15% + 10% = 25%
The laptop usually sells for £1320. Hence:
Discount = 25% of £1320 = 0.25 * 1320 = £330
Price paid by the student = £1320 - £330 = £990
The student paid £990 for the purchase of the laptop.
