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)

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

Answer:

they are not equal

Step-by-step explanation:

-8v-12=-8v-12

4v+12=4v+12

but you can solve it as an equation

-8v-12=4v+12

make v the subject

-8v-4v=12+12

-12v=24

divide both sides by-12

your answer is-2

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.

The inverse of the function y = 9x -4 is obtained by a reflection in the line at ( y = x ). Hence Option D is correct.

Each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point but is on the other side of the line. This transformation is known as a reflection over the line.

The inverse relation for y= 9x -4 will be calculated by putting the value of x equal to y or replacing x by y and y by x in the equation.

Hence Option D is correct.

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) =

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.
