Answer:

x = - 14, x = - 4

Step-by-step explanation:

Given

(x + 9)² = 25 ( take the square root of both sides )

x + 9 = ± [tex]\sqrt{25}[/tex] = ± 5

Subtract 9 from both sides

x = - 9 ± 5, that is

x = - 9 - 5 = - 14 or x = - 9 + 5 = - 4

Answer:

7740° / 45

Step-by-step explanation:

The sum of the interior angles is given by this formula: (n - 2) * 180°. So a regular 45-gon would have interior angles that add up to: (45 - 2) * 180°. = 43 * 180°. = 7740°. Now divide that by the 45 angles to find the measure of one interior angle

hope that helped :(

The measure of each exterior angle of a regular 45-gon is calculated using the formula: Exterior Angle = 360° / Number of Sides. Hence, each exterior angle of a 45-gon measures 8°.

In mathematics, the measure of each exterior angle of a regular polygon can be found using the formula: Exterior Angle = 360° / Number of Sides. So, to find the measure of an exterior angle in a 45-sided shape, or 45-gon, you would perform the calculation: 360° / 45 = 8°.

This indicates that each exterior angle of a regular 45-gon measures 8 degrees. This is a key concept to remember when working with regular polygons, as it can be used to determine other characteristics of the shape such as the sum of the exterior angles, which in any polygon is always 360°.

Lainey paid 30 cents (equivalent to $0.30) for each marker in the set.

To find the cost of 1 marker, you can divide the total cost by the number of markers.

Cost of 1 marker = Total cost / Number of markers

In this case, the total cost is $6, and the number of markers is 20.

Cost of 1 marker = $6/20

Simplifying the expression:

Cost of 1 marker=$0.30

Therefore, the cost of 1 marker is $0.30.

Think of the cost as being divided equally among all 20 markers. By dividing the total cost ($6) by the number of markers (20), we find the share of the cost for each marker ($0.30).

Question:

Answer:

Tom can cut 12 (15 inch pieces) from the two boards.

Step-by-step explanation:

We're first given foot measurements and we're asked to find the answer in inches. That means we must convert 8 feet to inches, which is a 1:12 inches conversion. 8 times 12 will give you 96, so now you will multiply that value by 2 because Tom has 2 8-foot long boards. That will give you 192 inches. Since the question is asking for 'how many 15 inch pieces he can cut from the two boards?', you will need to divide 192 inches by 15 to find the answer. This will give you 12.8 boards. Because you can't have parts of an object, the answer will be 12 whole boards.

Step-by-step explanation:

Let age of Marco's be "x" years

then according to question

Yolanda age will be "2x - 5"

Also in the question it is given that age Yolanda is 15 years.

then, 2x - 5 = 15

Adding 5 both sides of the equation, we will get

Answer:

It increases

Step-by-step explanation:

if b increases and the only other part of the equation is a constant it should increase as well. for example (the first value is b and the second is b-1) : (1,0) (2,1) (3,2) (4,3) (5,4)...

Answer:

The value increases

Step-by-step explanation:

Thinking process:

Let the expression be: b - 1

Let's say the value of b was 0, then the function will be: 0 - 1 = -1

Let the value of b be increased to 1, the expression will be 1 - 1 = 0

Let the value of b be increased to 2, the expression will be 2 - 1 = 1

Let the value of b be increased to 3, the expression will be 3 - 1 = 2

From the simulation, as the value of b increases, the net value becomes large.

Answer:

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

Step-by-step explanation:

The question states product so we know that we're multiplying.

A number and 5, and since the unknown variable is now [tex]x[/tex] we have [tex]5x[/tex] so far.

Then we need to make it so that it is 2 more.

[tex]5x+2[/tex]

Equals 9.

[tex]5x+2=9[/tex]

Solve for the unknown number.

[tex]5x=7[/tex]

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

Transforming the problem into the equation 5x + 2 = 9, where 'x' is the unknown number, we solve for 'x' by subtracting 2 from both sides and then dividing by 5, yielding 'x' = 7/5, or 1.4.

The mathematics problem described can be solved using simple algebra. The problem is stated as: two more than the product of a number and 5 equals 9. If we use the variable 'x' to represent the unknown number, then we can write the algebraic equation to represent this problem as 5x + 2 = 9. The next step would be to solve this equation to find the value of 'x'. In order to isolate 'x', you would first subtract 2 from both sides of the equation, yielding 5x = 7. To find 'x', you would then divide both sides of the equation by 5. The solution to the equation, and therefore the value of the unknown number 'x', would thus be 7/5 or 1.4.

Answer:

300 teenagers

Step-by-step explanation:

Let

x -----> the number of children

y ----> the number of teenagers

z ----> the number of adults

we know that

x+y+z=1,200 ----> equation A

4x+5y+6z=5,300 ---> equation B

y/x=3/8

y=(3/8)x ----> equation C

Substitute equation C in equation A and equation B and solve for x,z

x+y+z=1,200 ----> x+(3/8)x+z=1,200 ---> (11/8)x+z=1,200 -----> equation D

4x+5y+6z=5,300 --> 4x+5(3/8)x+6z=5,300 --> (47/8)x+6z=5,300 --> equation E

Solve the system of equations D and equation E by graphing

(11/8)x+z=1,200 -----> equation D

(47/8)x+6z=5,300 --> equation E

Answer:

"Domain of set B: {2, 4,-4, 0}"

Step-by-step explanation:

When it the set A,B,C (and others) are given in this form it means that the coordinate pairs are the domain and range of each set, respectively.

The first coordinate is part of the domain (x) and the second coordinate is part of the range (y).

For example, the domain of A is all the numbers that are the first in each coordinate pair, so domain of A would be 1, -1, and 6.

Likewise, the domain of B would be 2, 4, -4, and 0.

Hence,

Domain of set B: {2, 4,-4, 0}  --  is the correct answer.

Answer:

f(4) =123

Step-by-step explanation:

first your going to put in 4 for every w

then, think of PEMDAS.

after you solve your parenthesis, then exponents Multiply/devide Then, add/subtract.

2(4)^3 -5

2* 64 -5

128 - 5

123 = f(4)

To find the midpoint, add the two X values and divide by 2 and add the two Y values and divide by 2.

-1 + 5 = 4/2 = 2

5 +5 = 10 /2 = 5

Midpoint = (2,5)

Answer:

(2,5)

Step-by-step explanation:

The points are on the same y, which is 5, so we only have to find the distance between the x values.

Distance formula = [tex]M = \frac{x_{1} + x_{2} }{2}[/tex]

[tex]M = \frac{-1 + 5}{2}[/tex]

Mid = \frac{4}{2} [tex]

Mid = 2

To solve this plug in 9 for b and solve for a like so...

3a + 9 = 54

9 must be combined with 54. To do this you must subtract 9 from both sides. This will cancel out 9 from the left and bring it over to the right

3a + (9 - 9) = 54 - 9

3a + 0 = 45

3a = 45

Now we must isolate the a. To do this you have to divide 3 to both sides. This will make 3 on the left side 1 and bring 3 over to the other side

3a/3 = 45/3

1a = 15

a = 15
