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:

f(5) = 75

Hope that helps.

Answer:

75 is the correct answer for above questions.

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: x = 1

Answer:

40 degrees

Step-by-step explanation:

Okay first of all, we know that GD and HC are parallel, and based on the rules of parallel lines we also know that angle AIJ is equal to MLD. We also know that IJM is equal to 70 degrees because opposite angles are always congruent. Because AIJ is equal to MLD, we know that AIJ is 110 degrees. Because AE is a straight line, we can determine that MIJ is equal to 180-AIJ, or 70 degrees. The total meausre of a triangles angles is always 180, so to determine the measure of AMB (which is the same angle as IMJ) we simply need to subtract MIJ and IJM from 180. This is 180-70-70=40, so AMB = 40 degrees

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:

that is correct process

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:

Step-by-step explanation:

area of square A = s²

where A = 36

find: sides of squares

solution:

A = s²

just plugin values into the formula

36 = s²

s = √36

s = 6 cm

therefore, the length = 6 cm

                       width = 6 cm

Answer:

x ≈ 27.86

Step-by-step explanation:

Supplement means 180 degrees.

7x - 15 = 180

~Add 15 to both sides

7x = 195

~Divide 7 to both sides

x ≈ 27.86

Answer:

14 pieces of candy

Step-by-step explanation:

42/3 = 14

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:

2x = -22  so

X = -11

Answer:

x=-11

Step-by-step explanation:

2x+31=9

2x=-22

x=-11

Answer:

perpendicular slope = - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m of the line using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

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

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]

Answer:

s = 6

Step-by-step explanation:

In order to make a profit, you must sell more than $11 worth of socks, as that was how much it cost to buy the products to make them. If you sell each pair for $2, then you would need to sell 6 of them in order to make a profit. 6 times $2 is $12, and 12 > 11.

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:

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:

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
