Step-by-step explanation:

first find the slope:

(0,2)

(3,4)

(4-2)/(3-0)

y = 2/3x + b

2 = 2/3(0) + b

b = 2

y = 2/3x + 2

Answer:

-9 6 that is because the line has to be perpenducular to the other line

Step-by-step explanation:

Slope of line between points (-4, 6) and (5, -3)

=> Rise / Run

=> [6 - (-3)] / [(-4) - 5]

= 9 / (-9)

= -1.

Thus slope of perpendicular line

= -1 / (-1) = 1.

We have y = x + c.

When x = 1, y = -7.

=> (-7) = (1) + c, c = -8.

Hence y = x - 8.

Answer:

£92.40

Step-by-step explanation:

Discount price for David =1/5 of 60

= 1/5 × 60/1

= £12 (5 multiplied by 12 is 60)

Price for one child = £67

Price for 2 children= £67 × 2

= 134

Therefore discount price for the children,

134 × 60/100

= 134 × 6/10

= 134 × 3/5

= 26.8 × 3

= 80.4

= £80.40

Therefore total Price David pays,

£80.40 + £12

= £92.40

She bought 10 apples

Step-by-step explanation:

3x + 2 = 14

why i did this

because she bought 2 times the amount of bananas, it should be x + 2x = 3x

then i added two because she bought two extra apples

so 3x+2 = 14

subtract 2

3x = 12

x = 4

So now we substitute x in apples

2x +2 = # of apples

8 +2 = 10

check

10 - 2 = 8

8/2 = 4

4 = # of bananas

Answer:

Anna bought 4 bananas and 10 apples.

Step-by-step explanation:

System of Equations

Let's call the following variables:

x = number of bananas Anna buys

y = number of apples Anna buys

She buys 2 more apples than twice the number of bananas, thus:

y = 2x + 2      [1]

Anna bought 14 fruits in total, thus:

x + y = 14      [2]

Substituting [1] in [2]:

x + 2x + 2 = 14

Simplifying:

3x = 12

Dividing by 3:

x = 4

Substituting in [1]:

y = 2*4+2 = 10

Anna bought 4 bananas and 10 apples.

Answer:

No mode

Median 7

Step-by-step explanation:

Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.

Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Answer:

Mode: no mode

No mode because there are no repeating numbers.

Median=7

Put in order from least to greatest- 1,6,7,42,81

Find the one in the middle- 7

Answer:

10 or [tex]\sqrt{100}[/tex] (in surds)

Step-by-step explanation:

[tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] × [tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex]  = 5×2 = 10 or [tex]\sqrt{100}[/tex]

When the same square root multiply each other, they equal to the number in the square root. E.g. [tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] = 5 because [tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex]  also equals to [tex]\sqrt{25}[/tex], which is 5.

The equation of the blue line will be

y = 4x -3

The equation of the line that passes through the points (1, 1) and (2, 5) is y = 4x - 3.

We have,

To find the equation of the line that passes through the coordinates (1, 1) and (2, 5), we can use the point-slope form of the equation of a line.

The point-slope form of the equation is:

y - y1 = m(x - x1)

Where (x1, y1) represents one of the given points on the line, and m represents the slope of the line.

First, let's calculate the slope (m) using the given coordinates:

m = (y2 - y1) / (x2 - x1) = (5 - 1) / (2 - 1) = 4 / 1 = 4

Now, we can choose either of the given points and substitute its coordinates into the point-slope form. Let's use (1, 1):

y - 1 = 4(x - 1)

Simplifying the equation:

y - 1 = 4x - 4

y = 4x - 3

Therefore,

The equation of the line that passes through the points (1, 1) and (2, 5) is y = 4x - 3.
