Answer:

y = -2/3x + 5 1/3

Step-by-step explanation:

Find the slope:

4 - 6 / 2 - (-1) = -2/3

Put it in point-slope form:

y - 6 = -2/3(x + 1)

rearrange:

y - 6 = -2/3x - 2/3

y = -2/3x + 5 1/3

Answer:

8m

Step-by-step explanation:

We can convert the trapezium into a rectangle to make finding the area easier.

Say that the top side is 9m, and that the bottom side is 12m.

12 - 9 = 3

3/2* = 1.5

*Note that we are dividing by two to get the "overhang" of the bottom side.

Now that we have our overhang, we can find the length of the "t-rect"**.

**"T-rect" refers to a rectangle that has been formed by changing a trapezium into a rectangle.

12 - 1.5 = 10.5

9 + 1.5 = 10.5

The length of the t-rect is 10.5.

84/10.5 = 8

The height of the t-rect is 8m.

Since the height of the original trapezium is equal to the height of the t-rect***,

***Since we have only adjusted the length

this also means that 8m would also be the height of the original trapezium.

Now, there is a second way of doing this.

Find the median of 12 and 9.

9, 10, 11, 12

10, 11

The median is 10.5.

84/10.5 = 8

You get the same answer. These methods could be used as a solve-then-check method to another problem like these.

Answer:

  ∠4 = 145°

  ∠5 = ∠6 = 35°

Step-by-step explanation:

Angles 5 and 35° are corresponding angles, so are congruent.

Angles 5 and 6 are vertical angles, so are congruent.

Angles 4 and 35° are a linear pair, so are supplementary.

  ∠4 = 180° -35°

  ∠4 = 145°

  ∠5 = ∠6 = 35°

Answer:

this is a negative association

Step-by-step explanation:

Answer:

so, for each of the questions you have to change the expression into slope intercept form, then use that equation to graph a line on the graph.

i'll help you out:

11. y= 3/2x+5 (0,5) (-4,2 )

12.y= -2x-5 (0,-5) (-1,-3)

13. y= -2x-3 (0,-3) (-1,-1)

14. y= x-4 (0,-4) (4,0)

Step-by-step explanation:

the first expression is the slope intercept form and the parenthesis are the points.

Answer:

Initial value = 0

Step-by-step explanation:

The initial value is the amount of water in Jake's baby pool before his mom began to fill it with water at a rate of 2 gallons per minute.

We are told that the pool was empty, therefore, the initial value = 0.

Answer:

0

Step-by-step explanation:

Answer:

38+?=111

DCB=111-38

DCB=73

Answer:

73°

here's your solution

=> angle D + angle C = angle CBQ

=> Because we know that exterior angle

equal to sum of two opposite interior angles

=> D +C = CBQ

=> C + 38° = 111°

=> C = 111 - 38

=>. C = 73°

Step-by-step explanation:

Answer:

137 [tex]ft^2[/tex]

Step-by-step explanation:

1. Approach

Break up the given figure into smaller figures. One can break up this figure into a rectangle, and a triangle. After doing so, one can calculate the area of each of the smaller figures, and then add up the values.

2. Calculate the area of the triangle

If one were to cut the top figure off, one would get a triangle with a base of (3ft), and a height of (6ft). One can calculate the area of the figure using the formula;

[tex]\frac{base*height}{2}[/tex]

Substitute;

[tex]\frac{6*3}{2}\\\\= \frac{18}{2}\\\\\ 9[/tex]

3. Calculate the area of the rectangle;

Now, one is left with a rectangle with dimensions (16ft), and (8ft). To find the area of this figure, use the formula;

[tex]base * height[/tex]

Substitute;

[tex]16 * 8\\\\= 128[/tex]

4. Find the area of the whole figure

Now add the area of the triangle, and the area of the rectangle together.

(Rectangle) + (Triangle)

= 128 + 9

= 137

Answer:

A rational number an irrational number a whole number

Answer:

I would change 2x+4y=24 into x=12–2y

To do that, divide both sides by 2 and then subtract 2y on each side.

After that, substitute for x. 3x+2y=19 would become 3(12–2y)+2y=19.

Then solve.

3(12–2y)+2y=19

36–6y+2y=19

-4y+36=19

-4y=-17

y=4.25

Then, substitute y in either equation.

Either this:

3x+2y=19

3x+2(4.25)=19

3x+8.5=19

3x=10.5

x=3.5

Or:

2x+4y=24

2x+4(4.25)=24

2x+17=24

2x=7

x=3.5

Or you could solve it in the equation you created in the beginning:

x=12–2y

x=12–2(4.25)

x=12–8.5

x=3.5

The coordinates where the lines intercept are (3.5, 4.25).

Sorry for the long answer!

Answer:

The first one

Step-by-step explanation:

Because it already give you the y-intercept and you can solve x by doing 4 to 7 have to add 3 and x only have to add 1. It will give you a slope 3/1, so it is 3.

y=3x+1
