Step-by-step explanation:

The slope for each is 8

X is the slope.

y=mx+b

m is the slope and b is y intercept.

Equations listed below.

1. y=8x-8

2.y=8x-4

3. y=8x

4 y=8x+4

5.Y=8x+8

Answer: undefined

Step-by-step explanation: The slope is in a vertical line. So, when the slope is in a vertical line it is considered undefined.

Answer: 2

Step-by-step explanation:Just got it correct

Answer:

Step-by-step explanation:

The system of equation given is a simultaneous equation

7x + 2y = 24 ...... 1

2x + 1 = y ......... 2

Rearrange

7x + 2y = 24  .... *1

| 2x - y = -1 ..... * 2

Use elimination method

7x + 2y = 24

4x - 2y = -2

add

7x+4x = 24-2

11x = 22

x = 22/11

x = 2

Substitute x = 2 into 2

2x+1 = y

y 2(2)+1

y = 4+1

y = 5

Hence x = 2, y = 5

The system of equation is a simultaneous equation

Answer:

9/4 cups or 2 1/4 cups.

Step-by-step explanation:

Since she uses 3/4 for every 2 cups, then we have to find out what she makes per cup. We have to divide 3/4 in half and to do that, we want to scale up 3/4 making it 6/8 which is congruent to 3/4.

Now we divide 6/8 in half which is 3/8.

Then we multiply that by 3, 6 times 3 is 18. So now it is 18/8 cups. We can now scale down and simplify it more.

To do that, we just divide the fraction by 2 to make to denominator into 4. Because of that, our answer is 9/4 cups or 2 cups and 1/4 cup.

Cups of rice uses for every 3 cup of milk is [tex]1\frac{1}{8}[/tex] cups

Given:

Cups of rice uses for every 2 cup of milk = 3/4 cup

Find:

Cups of rice uses for every 3 cup of milk

Computation:

Cups of rice uses for every 1 cup of milk = (3/4) / 2

Cups of rice uses for every 3 cup of milk = [3 / 8]3

Cups of rice uses for every 3 cup of milk = 9 / 8

Cups of rice uses for every 3 cup of milk = [tex]1\frac{1}{8}[/tex] cups

Step-by-step explanation:

For something to be considered a triangle, the sum of its angles must be 180 degrees. Right angles are 90 degrees. And since triangles must have 3 angles, it could not work. 80+80 exceeds 180.

Answer:

5

Step-by-step explanation:

24x-40=8x+40

plus 40

24x=8x+80

then u subtract 8

then u get 16x

then 80 divied by 16

u get 5

Answer:

x = 5

Step-by-step explanation:

4(6x -10) = 8x + 40

24x - 40 = 8x + 40

now were going to get the variable and the numbers on different sides

24x - 40 + 40 = 24x

8x + 40 - 8x = 40

24x - 8x = 16x

40 + 40 = 80

16x = 80

now divide each side by 16

16x / 16 = x

80 / 16 = 5

x = 5

Answer:

Option B.

Step-by-step explanation:

Let 'g' represent the number of gallons of cleaning solutions.

Let 'c' represent the number of cups of bleach.

From the question given above, we were told that:

To make 5 gallons of cleaning solution, 3 cups of bleach is mixed in with water.

This implies that number of gallons (g) of the cleaning solution is directly proportional to the number of cups (c) of the bleach mixed with water i.e

g ∝ c

g = Kc

K is the constant of proportionality.

Next, we shall determine the relationship between g and c as follow

g = 5

c = 3

K =?

g = Kc

5 = K × 3

Divide both side by 3

K = 5/3

g = Kc

K = 5/3

g = 5/3 c

Thus, the relationship between g and c is:

g = 5c / 3

Next, we shall make c the subject of the formula. This is illustrated below:

g = 5c / 3

Cross multiply

3g = 5c

Divide both side by c

c = 3g/5

Next, we shall determine c when g = 10, 15, and 20.

This is illustrated below:

g = 10

c =?

c = 3g/5

c = (3 × 10)/5 = 30/5 = 6

g = 15

c =?

c = 3g/5

c = (3 × 15)/5 = 45/5 = 9

g = 20

c =?

c = 3g/5

c = (3 × 20)/5 = 60/5 = 12

Summary:

Num. of gallon (g) >> Num. of cup (c)

5 >>>>>>>>>>>>>>>> 3

10 >>>>>>>>>>>>>>> 6

15 >>>>>>>>>>>>>>> 9

20 >>>>>>>>>>>>>>> 12

Therefore, option B gives the correct table.

Answer:

s ≤ 60 - (3 ÷ 1/15)

Step-by-step explanation:

Minimum of blankets to crochet = 3

She has 60 days to crochet

She crochet at a rate of 1/15 of a blanket per day

Therefore to crochet 1 blanket

Number of days needed =x

1 blanket = rate per day * x days

1 = 1/15 * x

1 = 1/15x

Divide both sides by 1/15

x = 1 ÷ 1/15

= 1 × 15/1

= 1×15

x = 15

15 days needed to crochet 1 blanket

To crochet 3 blanket = 15 days × 3 blanket

=45 days needed.

Darcie can skip = 60 days - 45 days

= 15 days

The inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.

s ≤ 60 - (3 ÷ 1/15)

Solving the inequality

s ≤ 60 - (3 ÷ 1/15)

s ≤ 60 - (3×15/1)

s ≤ 60 - 45

s ≤ 15

Answer:

s ≤ 60 - (3 ÷ 1/15)

Answer:

  x = 21

Step-by-step explanation:

The angle T is an exterior angle to the ∆RST, so will be equal to the sum of the remote interior angles:

  T = 4x° +2x° = 6x°

T is also a same-side exterior angle with the one marked 54°, so is supplementary to that:

  T + 54° = 180°

  6x° + 54° = 180°

  x + 9 = 30 . . . . . . . . divide by 6

  x = 21 . . . . . . . . . . . . subtract 9
