f(x)=−x−2, find f(-6)f(−6)

Answer:

x = -4

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

x + 13 = 9

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 9 does indeed equal 9.

∴ x = -4 is a solution of the equation.

Answer:

x=-4

Step-by-step explanation:

So when solving a one-step algebraic equation you need to remember what you do to one side you have to do to the other side. In the problem x + 13 = 9 you need to subtract 13 from both sides to isolate x. So your problem should look like x = 9 - 13. Now all you have to do is solve 9 - 13 which is -4. So x = -4.

Mark me brainliest pls

Step-by-step explanation:

Answer:

Total tickets = 70

Total cost = $550

Adult's ticket = $9

Child's ticket = $5

Difference = 9 - 5 = $4

Assume all 70 are child's tickets

5 x 70 = 350

But the total cost was 550

550 - 350 = $200

The $200 must have come from Adult's tickets, which has a difference of $4.

200 ÷ 4 = 50

So there are 50 adult's tickets.

70 - 50 = 20

And there are 20 child's tickets.

Solve the Inequality for x

4x − 5 ≥ 7  

Move all terms not containing x to the right side of the inequality.

4x ≥ 12

Divide each term by 4 and simplify.

x ≥ 3

The result can be shown in multiple forms.

You graph it here

Answer:

Step-by-step explanation:

Alright, so this is basically just another equation, but then you see the greater than or equal to sign. How do I solve this? You may be asking. Well, treat it like an equation and worry about the sign later.

4x - 5 [tex]\geq[/tex] 7

Solve for x.

Add 5 to each side, then divide by 4 to each side.

4x [tex]\geq[/tex] 12

x [tex]\geq[/tex] 3  <----This is the answer.

Now for the graph. Look at the picture below:

That's what the graph should look like. Since it has a greater than or equal to sign, the line will be solid.

The graph is basically saying that anything that is greater than 3 (including 3) is counted, which is why that entire right side of 3 is shaded in.

Also, the way you should technically graph it is on a number line. So make a number line.

     -2   -1     0     1     2    3     4     5    6    7     8    9    10

<-----|-----|-----|-----|-----|-----€-----|-----|-----|-----|-----|-----|-----|----->

(Pretend € is the filled in dot).

So, the above number line is what it should look like when graphed. The € circle is filled in because we are including the 3.

1/6x or just 1/6

Step-by-step explanation:

the equation is y = mx + b and 1/6x is in place m which is the slope

stream blueberry eyes by MAX AND SUGA periodTt

The slope is also known as the gradient and the rate of change of the line. The slope of the line for the equation y= 1/6x + 1/4 is 1/6

The slope is also known as the gradient and the rate of change of the line, The equation of aline in slope intercept form is expressed as:

y = mx + b

where

m is the slope

b is the y-intercept

Given the equation y = 1/6x + 1/4

Compare

mx = 1/6x

m = 1/6

Hence the slope of the line for the equation y= 1/6x + 1/4 is 1/6

R = 2524 quarts/s

Step-by-step explanation:

Water flows through a pipe at a rate of 8600 cubic meters per hour.

We know that,

1 m³ = 1056.69 quarts

1 hour = 3600 s

Rate of flow of water = 8600 cubic meters per hour

[tex]R=8600\ \dfrac{m^3}{h}\\\\=8600\times \dfrac{1056.69\ \text{quarts}}{3600\ s}\\\\=2524.311\ \text{quarts/s}[/tex]

or

R = 2524 quarts/s

So, the rate of flow of water is 2524 quarts/s.

Answer:

the cafe served 6 regular coffees

Step-by-step explanation:

to get your answer you can multiply the percentage times the amount served in total

Total regular coffees served = 6.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given,

Total coffees served = 20

No. of regular coffees = 30% of 20

                                     = 30/100 × 20

No. of regular coffees = 6

Hence, Kelly's café served 6 regular coffees.
