Answer:

The equation is;

y = -2x + 1

the answer belonging in the green question mark is -2

Step-by-step explanation:

We start by getting the slope

The slope can be obtained by selecting any two points and applying the slope formula

let us select the points;

(1,-1) and (3,-5)

the slope formula is;

m = (y2-y1)/(x2-x1)

m = (-5-(-1)/(3-1)

m = (-5+1)/2 = -4/2 = -2

The y intercept is the value of y when x = 0

As it can be seen, y = 1 when x = 0

so the equation of the relation is;

y = -2x + 1

two brothers, richard and andrew share a sum £30 in the ratio 3:7 how much does each brother get?

Answers

7+3 = 10
30/10 = 3
3(3) = 9
7(3) = 21

richard gets 9
andrew gets 21

Answer:

Richard gets: £9

Andrew gets: £21

Step-by-step explanation:

To get the value of 1 part we have to add the total number of parts (3+7) and then divide them by the sum (30) 30/10 = 3 so we know 1 part is £3

Thus Richard gets: £3*3 = £9

And Andrew gets: £3*7 = £21

Are the ratios 5:3 and 6:4 equivalent?
yes
no

Answers

Answer:

nope

Step-by-step explanation:

The given ratios 5:3 and 6:4 are not equivalent.

What are Equivalent ratios?

Equivalent ratios are the ratios that are the same when we compare them. Example 1/2 and 2/4 are equivalent ratios.

Two or more ratios can be compared with each other to check whether they are equivalent or not.

The given two ratios are 5:3 and 6:4

We can write them as 5/3 and 6/4

Let us apply subtraction, if we get 0 then these are equivalent.

6/4-5/3

The LCM of 4 and 3 is 12

=(18-20)/12

The value of 18-20 is -2

=-2/12

We have to divide 2 by 12 we get -1/6.

=-1/6 not equal to 0

The ratios 5:3 and 6:4 are not equivalent.

Select the table representing a linear function. (Graph them if necessary)

Answers

Answer:

Step-by-step explanation:

There are a couple of ways you can go about solving this. The first is plotting all of the points and seeing which one makes a straight line. This is a little bit more time consuming but is great if you blank out and forget how to solve it. The faster way to do it is to see which function is decreasing/increase a constant amount between equal intervals. A increases but by a different amount each time. B decreases by 2 each time. C decreases at different intervals each time. And D does not consistently increase or decrease.

What shapes can the figure be broken into?
What is the area of the arrow?
I
7 ft
1 ft
2 ft
11 ft

Answers

Answer:

The arrow can be broken into a rectangle and a triangle.

And the area of the arrow is 22 ft^2

Step-by-step explanation:

Area of the rectangle:

length • width = 7 • 2 = 14 ft^2

Area of the triangle:

(base • height) / 2

You must add 1 + 2 + 1 in order to get the base which is 4

And to get the height, you must do 11 - 7 = 4 (height)

(4 • 4) / 2 = 8 ft^2

Add both areas together to get the area of the arrow:

14 ft^2 + 8 ft^2 = 22 ft^2
