Write the equation of the line that passes through (-3, -20) and (1, 4).

[tex]2(x+6)+40=4x\\2x+12+40=4x\\2x+12+40-4x=0\\2x-4x+52=0\\-2x+52=0\\-2x=-52\\x=26[/tex]

Basically multiply the 2 inside the bracket, then addition and subtraction. For the -2x=-52 part. Move -2 to divide the -52, you'll get x = -52/-2 as you'll get x = 26 because minus * minus or minus divide minus will always be positive.

Answer:

f(x)= -8x-3

Step-by-step explanation:

i got it right

Answer:

f (x) = -8x-3

Step-by-step explanation:

To rewrite the equation as a function of x, first isolate y on one side of the equation.

56x + 7y = -21

56x + 7y = -21

7y = -5x - 21

y = -8x -3

Then, substitute f(x) for y in the equation. This leaves the following as the correct answer.

f (x) = -8x-3

Answer:

11

Step-by-step explanation:

6x+7=8x-15

7=2x+15

22=2x

11=x

Answer:

11 =x

Step-by-step explanation:

6x +7=8x -15

Subtract 6x from each side

6x-6x +7=8x-6x -15

7 = 2x -15

Add 15 to each side

7+15 = 2x-15+15

22 =2x

Divide each side by 2

22/2 = 2x/2

11 =x

Answer:

7.30

Step-by-step explanation:

You take 7 and then do 3/10 which is .30

You put them together and get 7.30

Hoped that helped!

The 7 3/10 in decimal form is 7.3.

To write 7 3/10 in decimal form, to convert the fraction 3/10 to its decimal equivalent and then add it to the whole number 7.

To convert the fraction 3/10 to a decimal, divide the numerator (3) by the denominator (10):

3 ÷ 10 = 0.3

Now, add this decimal value to the whole number 7:

7 + 0.3 = 7.3

Answer:

Josh makes $36 more per hour than Greg.

Step-by-step explanation:

First, you need to determine the amount Josh earns per hour as you know that it takes him 5 hours of work to save $480:

5x=480

Now, you can solve for x:

x=480/5

x=96

Then, you need to determine the amount Greg earns per hour as you know that it takes him 8 hours of work to save $480:

8y=480

Now, you can solve for y:

y=480/8

y=60

96-60=36

According to this, the answer is that Josh makes $36 more per hour than Greg.

Answer:

Question 5: Angle B

Question 2:

AB: 1/2

AD: 1/4

Distance between point C and segment AB: 1/2

Question 3:

angle ABC corresponds to angle PQR

Segment AD corresponds to segment PS

from polygon ABCD to PQRS, the scale factor is 2/3

Question 4:

No, not all sides were multiplied by the same factor

Step-by-step explanation:

Question 5: Look at the order of the polygons:

1. A, B, C, D

2. E, F, G, H

3. I, J, K, L

There is no option for angle F so the answer is angle B

Question 2: Look at the information

- Scale factor of 4 -> 4 times corresponding size

AB: scaled size is 2 -> corresponding size is 2/4 -> 1/2

AD: scaled size is 1 -> corresponding size is 1/4

distance between point C and segment AB: 2 -> 2/4 -> 1/2

Question 3:

Look at the polygons, they are similar so...

1. Pick an order for the angles and apply it to both polygons:

Ex: ABCD PQRS (start with top left, go down, go down diagonally, go up diagonally)

2. Look at the order you picked and answer the questions:

*1:A 2:B 3:C 4:D -> 1:P 2:Q 3:R 4:S (so A corresponds to P)

angle ABC corresponds to angle PQR (1: A -> P, 2: B->Q, 3: C -> R)

Segment AD corresponds to segment PS (1: A -> P 4: D -> S)

3. For the scale factor compare the length of a segment in one of the polygons to the length of the corresponding segment in the other polygon

Ex: segment AD corresponds to segment PS -> AD = 2 units PS = 3

so from ABCD to PQRS, the scale factor is

AD/PS = AB/PQ = BC/QR = CD = RS

* "/" is divide -> fraction

so if I choose the length of AD and PS, the scale factor is AD/PS -> 2/3

Question 4:

If you look at the two polygons you can see that...

- segment CD was multiplied by a scale factor of 2 to get segment RS

- segment BC was multiplied by a scale factor of 1 to get segment QR

- segment ED was multiplied by a scale factor of 1 to get segment TS

- etc.

since the scale factors are not the same, the two polygons are not scaled copies of each other

Answer:

y-intercept: 1

equation of the line: y= -1/2x +1

Step-by-step explanation:

y=mx+b

1. plug in slope

  y = -1/2x +b

2. plug in the given point

  2 = -1/2(-2) +b

3. that gives 2=1+b

4. subtract 1 on both sides

  2 = 1 +b

  -1 = -1  

5. that gives 1=b

7. then plug in b for the equation y=mx+b and use the same slope

y= -1/2x +1

Answer:

Step-by-step explanation:

Since the two angles are same to be equal, then the two sides shown must also be equal.

Therefore you can say that 2x + 31 = 9

Subtract 31 from both sides of the equation

2x + 31 - 31 = 9 - 31  that will give you this:

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (- 2, - 3) ← 2 points on the line

m = [tex]\frac{-3-1}{-2-0}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2
