If f(x)=3x-9, what is the value of f(-8)

Answer:

x=-17 and x=-19

Step-by-step explanation:

-17+18=1

-19+18=-1

|-1| =1

Answer:

-17 and -19

Step-by-step explanation:

Absolute value equations have two problems and two solutions unless the original answer equals a negative-then it would be no solution.

x + 18 =1 subtract 18 from both sides to get x by itself

x = 1-18

x= -17

x +18 = -1  subtract 18 from both sides to get x by itself

x= -1 -18

x= -19

6/10 can be simplified but we don't need to worry about it right now. We only need to worry about simplifying 20/100:

20/100 → 10/50 → 5/25 → 1/5

Find common denominators

1/5 → 2/10

6/10

Now, add.

6/10 + 2/10 = 8/10

Therefore, the equation is true.

Best of Luck!

Answer:

Cylinder

explanation:

The formula for the volume of a cylinder is V=πr²h

To find the volume of a cylinder, the formula V = πr²h is used, where you multiply the square of the radius by π and then by the height, ensuring consistent units throughout.

To get the volume of a cylinder, you need to use the formula V = πr²h, where V stands for volume, π is a mathematical constant approximately equal to 3.14159, r represents the radius of the cylinder's base, and h denotes the height of the cylinder. To calculate the volume, first square the radius, then multiply that by π, and finally multiply by the cylinder's height. For example, if a cylinder has a radius of 0.750 cm and a height of 5.25 cm, you would calculate the volume as follows: 3.142 × (0.750 cm)2 × 5.25 cm, which equals approximately 9.278 cm3. Remember to use consistent units throughout the calculation.

Answer:

30 dollar discount

Step-by-step explanation:

Using the discount parameters given, the final sale price function of the guitar would be f(x) = x - 0.6x - 30 and the discount on initial price of $200 would be $90

Let initial price = x

First discount :

$50 off :

Second discount :

$3 off each $5 of sale price

Final discount :

The Final sale price :

f(x) = x - 0.6x - 30

Given an initial price, x = 200

Discount on price :

Final discount = 0.6x - 30

Discount on price of x = 200 :

0.6(200) - 30

120 - 30 = $90

Therefore, the discount on the price is $90

Answer:

Step-by-step explanation

two and a half batches?

Final answer:

Pauline used 1 cup of sugar and each batch of cookies requires 2/5 cup. By dividing 1 cup by 2/5 cup, we get 2.5 giving us ≈2 batches.

Explanation:

The question asks how many batches of cookies Pauline was able to make if she used 1 cup of sugar, with each batch requiring 2/5 of a cup of sugar. To find this, we can use a simple division process as our conversion factor. You divide the total amount of sugar used by the amount needed per batch.

Steps to calculate the number of batches:

Pauline uses 2/5 of a cup of sugar for each batch of cookies.

She used a total of 1 cup of sugar yesterday.

To find the number of batches made, divide the total amount of sugar by the amount per batch: 1 cup / (2/5 cup per batch) = 5/2 = 2.5 batches.

However, since you cannot make half a batch of cookies, Pauline must have made 2 batches.

To solve this, all we need to do is find the square root of the numerator and denominator in the fraction

When you see a giant root symbol, picture it like this ....

[tex]\frac{\sqrt{25} }{\sqrt{64} }[/tex]

So, let's solve!

√25 = 5

Answer:

60 degrees

Step-by-step explanation:

angle y is vertically opposite to angle a, (we can call it.)

angle x is supplementary to the other angle inside the triangle, which we can call angle b.

so, angle a is 60 degrees, as vertically opposite angles are equal

angle b is 60 degrees as supplementary angles = 180

based of the sum of angles in a triangle is 180 theorem;

60+60+unknown= 180

so unknown is 60 degrees

Hey there!

We can see on this number line that each tick mark represents one because every five marks, there is a difference of five.

Two marks to the left of 0 will be 0 minus 2, so -2.

Three marks to the left of -5 will be -5 minus 3, so -8.

Your answer is -8 and -2.

Hope this helps!

Final answer:

The integers that are being referred to are -8 and -2, which are negative whole numbers located on the left side of zero on a number line.

Explanation:

When plotted on the number line, integers represent whole numbers that can be positive, negative, or zero.

To identify the integers that are plotted, one would look for distinct marks or points on the number line that correspond to whole numbers.

Based on the data, we come to the conclusion that the numbers in question are -8 and -2.

The integers plotted on the number line are -8 and -2. The integer -8 is to the left of -2 on the number line.

These two numbers are examples of negative integers, which are located to the left of zero on a standard number line. The understanding of how to read a number line and identify the placement of integers is a key concept in mathematics, which allows for better comprehension of more complex mathematical ideas such as rational numbers, real numbers, and complex numbers.

Answer:

x = -2, y= 3

Step-by-step explanation:

y = 4x + 11

y = -2x - 1

Because both equations are equal to y, we can set them equal to each other

4x + 11 = -2x - 1

Add 2x to each side

4x+2x +11 = -2x+2x -1

6x +11 = -1

Subtract 11 from each side

6x+11-11=-1-11

6x = -12

Divide each side by 6

6x/6 = -12/6

x = -2

Now we need to find y

y = -2x-1

y = -2(-2)-1

   =4-1

   =3

Answer:

$594.75

Step-by-step explanation:

Given

yearly salary of Stephen= $41,236

No of weeks in a year = 52

Therefore, one week salary of Stephen = $41,236/52 = $793

to get one week salary divide total salary by number of weeks

5 weeks salary of Stephen = 5*793 = $ 3,965

agency fees = 15% of Stephen's 5 week salary

                      (15/100)*($ 3,965)  = $594.75

Therefore, Stephen has to pay $594.75 to the agency.

Answer: 15 + 23 =38

So n + n + 8 = 38

which means n + n = 30

and since the n's are the same, you just cut the 30 in 2 equal pieces. 15 and 15.

So n = 15, n + 8 = 23

15 + 23 = 38   :)

Answer:

Erin has $200

Step-by-step explanation:

Kevin = K

Erin = E

30% of Erin = 0.3E

K = E - 0.3E

K = 140

Substitute

140 = E - 0.3E

140 = 0.7E

Divide both sides of the equation by 0.7

E = 200

Erin has $200
