Answer:

We are given table for the prices for two different catering companies.

Company Initial Payment           Rate Per Employee

________________________________________

$135                                         $12

       $0                                           $15

We know, slope-intercept form of a linear equation:

y= mx+ b.

Where m is the slope ( Rate Per Employee with respect to the problem) and b is the y-intercept (Company Initial Payment).

Plugging m= 12 and b= 135 in slope-intercept form y=mx+b to get first equation.

y = 12x +135.

Plugging m= 15 and b= 0 in slope-intercept form y=mx+b to get second equation.

y = 15x + 0 or y = 15x.

Therefore, system of equations or Devoted Catering are

y = 12x +135.

y = 15x .

Step-by-step explanation:

Answer:

5 - 900

4.5 - 810

3 - 540

2.25 - 405

Step-by-step explanation:

5 x 180 = 900

4.5 x 180 = 810

3 x 180 =540

2.25 x 180 = 405

Answer:

thirteen hundredths=13/100

one hundred thirty thousandths=130/1000

cancelling by 10 this is =13/100

hence the question

Step-by-step explanation:

13/100 is equivalent to 130/1000 because if you simplify 130/1000 it becomes 13/100.

You simplify 130/1000 by dividing both sides by 10. 130 divided by 10 is 13, and 1000 divided by 10 is 100.

Multiplication is a simpler way of writing 'adding the same number multiple times'

Here you have added 5 2s together

So the answer is 5 times 2

Answer:

The answer is (2, ∞).

Step-by-step explanation:

The answer is (2, ∞) because both sides of the line will never meet and will forever increase on the [tex]y-axis^{}[/tex].

For (2, ∞)  intervals is the function increasing in the graph.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A function is increasing on an interval if for every point on that interval the first derivative is positive.

So we need to find the first derivative and then plug in the endpoints of our interval.

For interval (2, ∞) the function is increasing because both sides of the line will never meet and will forever increase on the y axis.

Hence, for (2, ∞)  intervals is the function increasing in the graph.

Answer:

x = [tex]\sqrt{53}[/tex]

Step-by-step explanation:

Using Pythagoras' identity on the upper right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Let the third side be d, then

d² + b² = a² , that is

d² + 8² = 11²

d² + 64 = 121 ( subtract 64 from both sides )

d² = 57

Using Pythagoras' identity on the lower right triangle, then

x² + c² = d²

x² + 2² = 57

x² + 4 = 57 ( subtract 4 from both sides )

x² = 53 ( take the square root of both sides )

x = [tex]\sqrt{53}[/tex]

Step-by-step explanation:

x =121.42

Answer:

x = 82.35

Step-by-step explanation:

42/51 = x/100

cross multiply, then you get

42*100 = 51*x

4200/51 = 51x/51

x = 82.35

180. 180 ÷ 5 = 36, and 180 ÷ 3 = 60, and 60 + 36 = 96.

Answer:

x (x + 4) = 45

x^2 + 4x - 45 = 0

factor

(x + 9)(x - 5) = 0

x = -9 or 5

your length cannot be negative so x= 5 and x+4 =9

Given : A inequality is given to us . The inequality is 19 ≥ t + 18 ≥ 11 .

To Find : The correct option between the given ones . To write the compound inequality with integers .

Solution : The given inequality to us is 19 ≥ t + 18 ≥ 11 . Let's simplify them seperately .

[tex]\red{\tt Case\:1}[/tex]

⇒ 19 ≥ t + 18 .

⇒ t + 18 ≤ 19 .

⇒ t ≤ 19 - 18 .

⇒ t ≤ 1 = 1 ≥ t . ..................(i)

[tex]\red{\tt Case\:2}[/tex]

⇒ t + 18 ≥ 11 .

⇒ t ≥ 11 - 18.

⇒ t ≥ -7 . ....................(ii)

On combing (i) & (ii) .

This means that t is less than or equal to 1 but greater than or equal to (-7) .

Answer:x=8

Step-by-step explanation:

5/6x + 7 = 17

Subtract 7 from both sides:

5/6x = 10

Divide both sides by 5/6:

X = 10/ 5/6

When dividing a number by a fraction flip

The fraction over and multiply:

X = 10 x 6/5

Simplify

X = (10x6)/5

X = 60/5

X = 12

The answer is x = 12

Answer:

[tex]\boxed {x = 12}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]\frac{5}{6}x + 7 = 17[/tex]

-Subtract both sides by [tex]7[/tex]:

[tex]\frac{5}{6}x + 7 - 7 = 17 - 7[/tex]

[tex]\frac{5}{6}x = 10[/tex]

-Multiply both sides by [tex]\frac{6}{5}[/tex], which is the reciprocal of [tex]\frac{5}{6}[/tex]:

[tex]x = 10 \times (\frac{6}{5})[/tex]

[tex]x = \frac{10 \times 6}{5}[/tex]

[tex]x = \frac{60}{5}[/tex]

-Divide [tex]60[/tex] by [tex]5[/tex]:

[tex]x = \frac{60}{5}[/tex]

[tex]\boxed {x = 12}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]12[/tex].
