Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 30)

Point (20, 60)

Step 2: Find slope m

Answer:

2.25

Step-by-step explanation:

we should find the slope of table, bc question is that "find the rate of change" so pick up two any points

(3; 5.00)

(4; 7.25)

Formula of Slope:

[tex] \frac{y1 - y2 }{x1 - x2} [/tex]

[tex] \frac{5 - 7.25}{3 - 4} = 2.25[/tex]

Answer:

2: 67

3:67

4: 113

Step-by-step explanation:

Answer: 67 degrees, 67 degrees, 113 degrees

Step-by-step explanation:

Angle 2: 180-113= 67 degrees

Angle 3: angle 3=angle 2

67 degrees

Angle 4: angle 4=angle 1

113 degrees

Answer:

(-2,4)

Step-by-step explanation:

When you reflect over y = x, the x and y change places.  F' is at (4,-2) .

Answer: (-2, 4)

Step-by-step explanation:

Swap x and y coordinates since you're reflecting over y=x.

(4, -2)==>(-2, 4) ==> The slope between these two points should be -1(y=-x). That way, you know the graph is being reflected over y=x.

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

m=(4-(-2))/(-2-4)

m=(4+2)/(-6)

m=6/(-6)

m=-1 ==> These two points are confirmed to be reflected over the line y=x.

Old coordinates: (-2, 4)

Y = 4 x - 9

y = - 3 x - 5

Answer:

25 + 15x < 45 + 7x

Step-by-step explanation:

Given:

Floors, Inc. Fixed charges = $25

Floors, Inc. Variable charges = $15 per hour

R rug clean Fixed charges = $45

R rug Variable charges = $7 per hour

Computation:

Assume number of hour = x

Floors, Inc. total cost = 25 + 15x

R rug  total cost = 45 + 7x

So,

25 + 15x < 45 + 7x

Answer:

x = 2.4

I'm not sure how the answer is 4.5 but I'm pretty sure this is right unless I'm missing something

Step-by-step explanation:

So we need to find how much shorter is the short line compared to the longer one. Basically we need a scale factor, for this we can use the side lengths already given to us, 10 and 15. So u can choose either enlarge the short line or shorten the longer one.

If u want to enlarge the short line then do 15/10 which is 3/2 which u will then multiply the shorter line's equation with it, if u want to shorten the longer line then do 10/15 which is 2/3 and multiply the longer lines equation with it.

I'll be using the 3/2 one cause why not:

3/2(x + 6) = 4x + 3

3/2x + 18/2 = 4x + 3

multiply the entire equation with 2 to make 3/2 no longer a fraction

(3/2x + 18/2 = 4x + 3)2

6/2x + 18 = 8x + 6

3x + 18 = 8x + 6

subtract 18 from both sides

3x = 8x - 12

subtract 8x from both sides

-5x = - 12

divide -5 from both sides

x = 2.4

U can input x into the equation to check:

3/2(2.4 + 6) = 4(2.4) + 3

12.6 = 12.6, it's right

Answer:

9156.24

Step-by-step explanation:

calculator

Answer:

its 9156.24

Step-by-step explanation:

Given:

The value is tan(195°).

To find:

The exact value of tan(195°).

Solution:

We have,

[tex]\tan (195^\circ)=\tan (180^\circ+15^\circ)[/tex]

[tex]\tan (195^\circ)=\tan (15^\circ)[/tex]      [tex][\because \tan (180^\circ-\theta)=\tan \theta][/tex]

It can be written as

[tex]\tan (195^\circ)=\tan (45^\circ-30^\circ)[/tex]

[tex]\tan (195^\circ)=\dfrac{\tan (45^\circ)-\tan (30^\circ)}{1+\tan (45^\circ)\tan (30^\circ)}[/tex]      [tex][\because \tan (A-B)=\dfrac{\tan A-\tan B}{1+\tan A\tan B}][/tex]

[tex]\tan (195^\circ)=\dfrac{1-\dfrac{1}{\sqrt{3}}}{1+(1)(\dfrac{1}{\sqrt{3}})}[/tex]

[tex]\tan (195^\circ)=\dfrac{\dfrac{\sqrt{3}-1}{\sqrt{3}}}{1+\dfrac{1}{\sqrt{3}}}[/tex]

[tex]\tan (195^\circ)=\dfrac{\dfrac{\sqrt{3}-1}{\sqrt{3}}}{\dfrac{\sqrt{3}+1}{\sqrt{3}}}[/tex]

[tex]\tan (195^\circ)=\dfrac{\sqrt{3}-1}{\sqrt{3}+1}[/tex]

Therefore, the exact value of tan(195°) is [tex]\dfrac{\sqrt{3}-1}{\sqrt{3}+1}[/tex].

Step-by-step explanation:

Answer:

meema, papa, and then auntie jo

Step-by-step explanation:

you need to find the slope of each of them and then determine which one is the fastest and which one is the slowest.

meema: 48-24/4-2 = 4/2 = 2

papa: 40-24/5-3 = 16/2 = 8

auntie jo: 45-18/5-2 = 27/3 = 9

Answer:

-5x > 10

Step-by-step explanation:

1. We know that when -14 thrown to the right hand side, it will turn to +14

2. +14 -4 = +10

3. Left hand side will remain -5x

4. Hence, -5x > 10

5. and the equation divided by -5, the > sign will change to <

6. x< -2

7. Since you're finding the missing step so it's -5x > 10

D=5

to make the $75 for the $125

Answer:

What equation will you use to solve this word problem?

✔ 50 + 15d = 125

Answer:

BCE= 115    ECD=65

Step-by-step explanation:

(5x+10)+(3x+2)=180

8x+12=180

8x=168

x=21

5(21)+10=115

3(21)+2=65

Answer:

<BCE=115°

<ECD=65°

And their sum is 180°

Step-by-step explanation:

< BCE + <ECD =180° ( Being sum of supplementary angle which is formed in the given diagram is 180°)

(5x + 10)° + (3x + 2)°= 180°

5x + 10 + 3x + 2 = 180°

5x + 3x + 10 +2 = 180°

8x + 12= 180°

8x = 180°-12°

8x = 168

x= 168/8

x=21°

Now,

<BCE = 5x+10

= 5*21+10

=105+10

=115

<ECD

= 3x+2

= 3*21+2

=65

Answer:

A liter of milk cost $0.75 and a loaf of bread cost $1.75

Step-by-step explanation:

Let the liters of milk by represented by m

Let the loaves of bread by represented by b

Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11

3m + 5b = 11...... Equation 1

A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10

4m + 4b = 10.... Equation 2

Combining the Equations

3m + 5b = 11...... Equation 1

4m + 4b = 10.... Equation 2

We solve using the Elimination method

Multiply Equation 1 by 4 and Equation 2 by 3 to eliminate m

12m + 20b = 44..... Equation 3

12m + 12b = 30....... Equation 4

Substract Equation 4 from Equation 3

8b = 14

b = 14/8

b = $1.75

Solving for m

3m + 5b = 11...... Equation 1

3m + 5($1.75) = 11

3m + $8.75 = $11

3m = $11 -$ 8.75

3m =$ 2.25

m =$ 2.25/3

m = $0.75

Therefore,

a liter of milk cost $0.75 and a loaf of bread cost $1.75

Answer:

80%

Step-by-step explanation:

home work = 10%

project grade = 50%

final exam = 40%

so

homework  = 72

100=10

72=?      cross multiply and get 7.2%

project grade = 80

100 = 50

80 = ?   cross multiply and get 40%

final exam = 82

100 = 40

82 = ?     cross multiply and get 32.8%

then add them altogether getting a total of 80%.

Answer:

You will get 75 cards

Step-by-step explanation:

The answer is 32

Emily signed 2/5 so 75 divided by 5 is 15

15x2 is 30

75-30=45

45 divided by 1/9 is 5

30+5=35

so then 45-5=40

20% of 40 is 8

30+5+8 = 43

75-43=32

Answer: q = 13

because p and q are inverse
