What is the value of (5ý + 3) + 5?​

Answer: C f(x) = 16*(1/2)^ (x-1)

Step-by-step explanation:

You are dividing by 2 each time

Answer:

fast multiply 5 by 39 to get the total age of the five people now as you are told those per 5 so imagine the six person being you if you enter you're going to add to their ages so they mean is going to be for six people so take the six people x their mean age now we have two different total ages for the five people and for the six people subtract the total age of the 5 from the 6th total ages to get the age of the person who entered the room if you don't understand please ask me and be willing to help

Answer:

The age of the person who entered the room is 21.

Step-by-step explanation:

Mean of 5 peoples = 39

i.e.

Sum / 5 = 39

Sum = 39 x 5

Sum = 195

Mean after one person enters the room = 36

Let x be the age of the new person.

Then

Mean = (Sum + x)/ 6

36 = (195 + x)/6

36 x 6 = 195 + x

216 = 195 + x

x = 216 - 195

x = 21

Answer:

O Asher found multiples of 10, not factors of 10.

O Asher should have gotten this as the answer: 1,2,5, and 10

Step-by-step explanation:

Here is the full question :

Asher is asked to find the factors of 10. His work is below. 10 x 1 10 10 x 2 20 10 x 3 30 So, the factors of 10 are 10, 20, and 30 Which statements are true of Asher's work and his answer? Check all that apply

O Asher made errors in multiplication.

O Asher found multiples of 10, not factors of 10.

O Asher should have multiplied 10 x 4 as well.

O Asher should have gotten this as the answer: 1,2,5, and 10

O Asher should have gotten this as the answer: 10, 20, 30 40,

Factors are numbers that can divide a number exactly so that there would be no decimals.

The factors of 10 are 1,2,5,10

These numbers divide 10 exactly.

A multiple of a number are numbers derived by multiplying a number by an integer

Multiples of 10 include = 10, 20 , 30, 40, 50, 60, 70, 80, 90, 100

Answer:

Step-by-step explanation:

Answer:

10.9

Step-by-step explanation:

Your gonna use the Pythagorean theorem to find x

5^2+x^2=12^2

x^2= 12^2- 5^2

x^2= 144-25

x^2= 119

x= root 119 or 10.9

Answer:

Points of intersection of these graphs are (-2, -3) and (0.6, 4.8).

Step-by-step explanation:

Equation of the circle → (x - 2)² + y² = 25 ---------(1)

                                   → (x - 2)² + (y - 0)² = 5²

By comparing this equation with the standard equation of the circle,

(x - a)² + (y - b)²= r²

Here (a, b) is the center and r is the radius of the circle.

Therefore, center of the circle is (2, 0) and radius = 5 units

Second equation is a linear equation → y = 3x + 3 -------(2)

x-intercept of the equation → x = -1

y-intercept of the equation → y = 3

By graphing these equations we can get the point of intersections.

Solving these equations algebraically,

Substitute the value of y from equation (2) in the equation (1),

(x - 2)² + (3x + 3)² = 25

x² - 4x + 4 + 9x² + 18x + 9 = 25

10x² + 14x - 12 = 0

5x² + 7x - 6 = 0

x = [tex]\frac{-7\pm \sqrt{7^2-4(5)(-6)}}{2(5)}[/tex]

x = [tex]\frac{-7\pm \sqrt{169}}{10}[/tex]

x = [tex]\frac{-7\pm13}{10}[/tex]

x = -2, 0.6

From equation (2),

y = -3, 4.8

Therefore, points of intersection of these graphs are (-2, -3) and (0.6, 4.8).

at first write the first coefficient just below it then multiply with 2 ( if there is x-2 we should take 2 and vice versa ) keep repeating this process

Answer:

Yes

Step-by-step explanation:

Yes, the difference in composition and quantity from the blubber of baby dolphins in comparison to that of adults allows them to regulate and maintain their body temps much more efficiently. This in term allows baby dolphins to have a much higher probability of survival as opposed to if their blubber was the same as adults. Once they reach a certain age the composition begins to change since they are able to more easily adapt to their environment.

Answer:

Total number of balloons= 160

Step-by-step explanation:

Giving the following information:

Number of balloons inflated by Zoey= 24

Proportion of balloons inflated= 15%

To calculate the total number of balloons, we need to use the following formula:

Total number of balloons = Number of balloons inflated by Zoey / Proportion of ballons inflated

Total number of balloons= 24 / 0.15

Total number of balloons= 160

Answer:

no

Step-by-step explanation:

Answer:

[tex]y = x - 8[/tex]

Step-by-step explanation:

Slope-intercept form is:

[tex]y = mx + b[/tex]

Where m = slope and b = y-intercept.

It is stated that the slope of the line is 1.

It is stated that the line includes the point (0, 8)

To find the y-intercept, we can just inverse the slope-intercept form to solve for b.

[tex]b =y-mx[/tex]

We know that the point (8, 0) falls on the line, so that's what we'll use for x and y.

Then, we just have to plug those numbers in, as well as the slope.

[tex]b = 0 - (1)(8)[/tex]

Simplify.

[tex]b = 0 - 8[/tex]

Simplify again.

[tex]b = -8[/tex]

Now, we know that b = -8.

All we have left is to plug the slope and y-intercept into the slope-intercept form.

[tex]y = x - 8[/tex]

Answer:

x = 3 and y = 6

Step-by-step explanation:

Hope this helps :)

Answer:

x = 3, y = 30

Step-by-step explanation:

Since the 3 sides are congruent then the triangle is equilateral.

The 3 angles are congruent and equal tp 60°

Evaluate each of the angles to 60 and solve for x and y , that is

25x - 15 = 60 ( add 15 to both sides )

25x = 75 ( divide both sides by 25 )

x = 3

and

2y = 60 ( divide both sides by 2 )

y = 30
