WILL MARK BRAINLIEST:

Bas_tet [7]

Answer:

The answer to your question is: y = -2x + 10

Step-by-step explanation:

Data

Point = (1, 8)

Line y = x/2 + 3

perpendicular

slope = 1/2 but the lines are perpendicular, then slope = -2

Equation

( y - y1) = m ( x - x1)

(y - 8) = -2(x - 1)

y - 8 = -2 x + 2

y = -2x + 2 + 8

y = -2x + 10

Decrease £19064.67 by 9.5% Give your answer rounded to 2 DP.

alina1380 [7]

Answer:

New amount (decrease) = £17253.53

Step-by-step explanation:

Given the following data;

Amount = £19064.67

Percentage = 9.5%

To find the percentage decrease;

$Percentage \; cost = \frac {9.5}{100} * 19064.67$

$Percentage \; cost = 0.095 * 19064.67$

Percentage cost = £1811.14

New amount (decrease) = Original amount - percentage cost

Substituting into the equation, we have;

New amount (decrease) = £19064.67 - £1811.14

New amount (decrease) = £17253.53

If x=9 and y=- -2 evaluate the following expression: x+y

mel-nik [20]

Answer:

x + y = 11

Step-by-step explanation:

You would need to substitute the numbers into the expression.

Evaluate means that we need to work out what the answer would be.

x + y is equivalent to 9 - - 2.

- - is equivalent to +.

Therefore you would do 9 + 2, which equals 11.

Hope this helps :)

Select the correct answer. A triangle with vertices at A(0, 0), B(0, 4), and C(6, 0) is dilated to yield a triangle with vertice

erma4kov [3.2K]

Answer:

* The scale factor of the dilation is 2.5

Step-by-step explanation:

* Lets talk about dilation

- A dilation is a transformation that changes the size of a figure.

- It can become larger or smaller, but the shape of the

figure does not change.

- The scale factor, measures how much larger or smaller

the image will be

- If the scale factor greater than 1, then the image will be larger

- If the scale factor between 0 and 1, then the image will be smaller

* In the problem

- The vertices of the triangle is A (0 , 0) , B (0 , 4) , C (6 , 0)

and its image A' is (0 , 0) , (0 , 10) , (15 , 0)

∵ 10 ÷ 4 = 2.5

∵ 15 ÷ 6 = 2.5

∴ The scale factor is 2.5

∵ 2.5 > 1

∴ The image of the triangle will be larger

* The scale factor is 2.5
