mark gets a haircut every two weeks. he spends 15 dollars and 3 dollars for a tip for each haircut. how much does he spend on haircuts in one year

Answer:

x = -3

Step-by-step explanation:

The equation of any linear function is y = mx + c, where m is the gradient and c is the y-intercept

The equation of the function is y = -x + 4

The gradient is negative one (hence 1x) and the y-intercept is 4

We need to find what x equals when the y = 7

7 = -x + 4

Rearrange

7 - 4 = -x

-x = 3

x = -3

Answer: (66/11)^3-6*8 = 168

              10/7+28-51/2 = 23.93

Step-by-step explanation:

First set:

(66/11)^3-6*8

(66/11)=6

(6)3-6*8

6^3=216

216-6*8

6*8=48

216-48= 168

Second Set:

10/7+28-51/2

= 206/7-5.5

= 23.928571

we would want to round that answer to 23.93

optional answers:

24

23.9

23.929

etc.

There's your answer

correct me if I'm wrong, or if this wasn't what you were looking for

Good Luck!

Edit:

the exponent is the number 3 also for the 1 question and for the 2 question the 10 and the 7 the a fraction and the 1 and two is a fraction

Answer:

You can start with any statement in the form a = a. Then add the same variable term to both sides, and add the same constant term to both sides. Combine like terms on each side.

Answer: 3 hours

Step-by-step explanation:

25 x 3 = 75

90 - 75 = 15 ( aka 1 service call)

Hope this helps!

Answer:

3 hours

Step-by-step explanation:

$25(3 hours)=$75

$75+$15=$90

Answer:

y = 2x

Step-by-step explanation:

Coordinates:

(1, 2)

(0, 0)

Slope = 2/1 = 2

y = mx + b

2 = 1 * 2 + b

2 = 2 + b

b = 0

So:

y = 2x

Answer:

w = 90/65 (125)

Step-by-step explanation:

Since you are trying to find how much Gabriel can type in 125 seconds, you have to find how much he can type in 1 second. Then you can multiply by 125 to get your answer!

Answer:

$4,351.48

Step-by-step explanation:

This is because if you take 6,000 and use the part over whole method, 6,000 x 100 = 600,000 divided bt 105.5 = 5,687.20, continue that with the same numbers, except you replace the part with the last answer you got.

6,000 after 6 months

5,687.20 after 5 months

5,390.72 after 4 months

5,109.68 after 3 months

4,843.30 after 2 months

4,590.81 after 1 month

4,351.48 as the initial deposit.

I took (5,0) and (0,5)

x-x1/x2-x1=y-y1/y2-y1

x-5/0-5=y-0/5-0

(x-5)*5=y*(-5)

x-5=-y

y+x=5

Step-by-step explanation:

range of the function is [- infinite, infinite]

if x is determined as R number then even range of the function will be R ,real numbers.

Answer:

3 hours

Step-by-step explanation:

Let the number of hours worked = x

Delicious Doing caterers events at a flat rate $500 plus $100 per hour after the first 2 hours.

$500 + $100 × x

500 + 100 × 1

After the first 2 hours = $500 + $100

= $600

After the first 3 hours = $500 + $100 × 2

= $700

Cathy's Catering has a flat rate of $620 per event plus $70 per hour after the first three hours.

$620 + $70 × x

620 + 70x

After the first 3 hours

= $600 + $70

= $670

What is the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings?

The Inequality is given as:

Cathy's Catering for < Delicious Doings

620 + 70x < 500 + 100x

Collect like terms

620 - 500 < 100x - 70x

120 < 30x

120/30 < x

4 < x

Therefore, the most amount of hours the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings is 3 hours

Answer:

  a:  12^18

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)(a^c) = a^(b+c)

__

All of the bases are the same in this expression, so the exponents add:

  12^3 * 12^9 * 12^4 * 12^2 = 12^(3+9+4+2) = 12^18 . . . . matches choice A

Step-by-step explanation:

Answer:

[tex]d = 10[/tex]

Step-by-step explanation:

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(-2-6)^2+(4-(-2))^2}[/tex]

[tex]d = \sqrt{(-8)^2+(4+2)^2}[/tex]

[tex]d = \sqrt{64+(6)^2}[/tex]

[tex]d = \sqrt{64+36}[/tex]

[tex]d = \sqrt{100}[/tex]

[tex]d = 10[/tex]

Answer:

10 units

Step-by-step explanation:

( x1, y1) =A(6,-2)

(x2, y2) =B(-2,4)

Using distance formula,

AB ^2 = (x2-x1) ^2 +(y2-y1) ^2

=(-2-6)^2 +(4+2)^2

=64+36

=100

Therefore, AB=10 units

[tex]8 \times 103 < 9 \times 100[/tex]

This is because :-

[tex] = 8 \times 103[/tex]

[tex] = 824[/tex]

is smaller than :-

[tex] = 9 \times 100[/tex]

[tex] = 900[/tex]

As , 824 < 900

Therefore , the correct answer is :-

Answer:

9 time 100 is the right answer

Answer: image below is the answer

Step-by-step explanation:

$1.80 + $1.20 = $3.00  <  $1.86 + $1.23  <  $2.00 + $1.50 = $3.50

Double these supplies will cost between 2 × $3.00 and 2 × $3.50.

2 x $1.23 = $2.46

Think about more items Kira could buy so that her total cost is more than $4 but less than $6.

$1.80 + ($1.10 x 2) = $4.00  <  $1.86 + ($1.23 x 2)  <  $2.00 + ($1.25 x 2) = $4.50

Think about more items Ida could buy so that her total cost is more than $8 but less than $9.

Answer: 55 degrees / Acute angle.

Step-by-step explanation:

The angle is less than a right angle, bent forward so it's less than 90 degrees, meaning it's an acute angle.
