Answer:

[tex]\boxed{\sf{-31}}[/tex]

Step-by-step explanation:

If you want to solve this, you must expand by a distributive property.

Distributive property:

3(2x-7)-2(3x+5)

3(2x-7)

3*2=6

3*7=21

Rewrite the problem.

6x-21

6x-21-2(3x+5)

-2(3x+5)

-2*3=-6

-2*5=10

-6x-10

Rewrite the problem down.

6x-21-6x-10

Combine like terms.

6x-6x-21-10

Add similar into their elements.

6x-6x=0

-21-10

Solve.

Subtract the numbers from left to right.

-21-10=-31

-31

Answer:

4000 meters

Step-by-step explanation:

Shortest run was 5 laps (2000 meters), and longest was 15 (6,000 meters)

The true statement about h(x) is: The function is increasing on the interval [0, ∞).

A linear function can be represented by a line. The standard form for this equation is: ax+b , for example, y=2x+7. Where:

a= the slope.If:

             a> 0 , the function is increasing;

             a< 0 , the function is decreasing;

b=the constant term that represents the y-intercept.

The domain of a function is the set of input values for which the function is real and defined. In other words, when you define the domain, you are indicating for which values x the function is real and defined.

While the domain is related to the values ​​of x, the range is related to the possible values ​​of y that the function can have.

You should convert the text of the question into a math expression.

[tex]h(x)=3*\sqrt{x}[/tex]

Like the coefficient a is greater than zero (a>0), the function is increasing.

The equation has a square root, so, the values of x can not present negative values. Therefore, x≥0. Consequently, the values of y (range) for this function will be greater than or equal to zero (y≥0). See the attached image.

The range is:

b) h = height

Step-by-step explanation:

The sum of co-interior angle = 180°

Now,

2x + 7x = 180°

9x = 180°

x = 180° ÷ 9

x = 20°

Answer:

x = 20

Step-by-step explanation:

Co-interior angles (also called same-side interior angles) are two angles that are on the same side of the transversal and on the interior of (between) the two parallel lines.

Same-side interior angles theorem:  If two parallel lines are cut by a transversal, then the same side interior angles are supplementary (add up to 180º).

Therefore, if 2x and 7x are co-interior:

⇒ 2x + 7x = 180

⇒ 9x = 180

⇒ x = 20

Answer:

The repeating decimal is 85/99 = 0.858585...

Step-by-step explanation:

A rational number in the form of a fraction can be represented as a decimal by dividing the numerator by the denominator. For example, this is how we get 0.75 = 3/4: (first screenshot)

Now let's divide 85.0000... by 99. Find enough decimal digits in the numerator so we can see whether the decimal terminates or starts to repeat. (second screenshot) Since the number 850 repeats itself, this is a repeating decimal.

Answer:

x = 5

Step-by-step explanation:

-x² + 10x - 25 = 0

x = {-10±√((10²)-(4*-1*-25) / (2*-1)

x = {-10±√(100-100)} / -2

x = {-10)/-2

x = 5

Comprobación:

- (5²) + 10*5 - 25 = 0

-25 + 50 - 25 = 0

Answer: Answer:

A. is your answer

When using the Slope Method, your answer is y - 5 = 4(x - 2).

Hey there!

Here we have a fraction

2/6.

The 2 is the numerator, and 6 is the denominator.

How to remember where the numerator and the denominator is?

Well, please remember the following:

The Denominator is Down

Hence, 6 is the denominator of this fraction.

Hope everything is clear.

Answer:

7/6

Step-by-step explanation:

in order to find the answer you have to -5/6 by 1/3 and then you get 7/6 so technically you have to minus it

Step-by-step explanation:

I guess the 3.14 is to be used for pi (and not r, which is what we need to find out).

the volume of a cylinder is ground area × height.

the ground area is the area of a circle, which is pi×r².

so, we have

pi×r²×height = 115 cm³

3.14×r²×7.7 = 115 cm³

3.14×r² = 14.93506494...

r² = 4.756390107...

r = 2.18091497... cm

Answer:

B 24 million years old

Step-by-step explanation:

i did this quiz a long time ago tho so it might be B or D

Answer: No solutions

- by graphing-

         First I will simplify:

8B + 7v - 5 equals -11 + 15b​

8b + 7v - 5 = -11 + 15b​

7v = -6 + 15b​

7v = -6 + 7b​

         Let's graph this and see what happens!

-> I will graph y = 7x and y = 7x - 6

-> See attached.

-> Since there are no points of intersection (they have the same slope), there is no solutions.

Answer:

12(4+3)

Step-by-step explanation:

Factor out all of the problems.

Starting with 4(12+4)

This means (4*12)+(4*4)

48+16 is the answer to this

this isn't 48 + 36

12(4+3) is next

12*4 = 48

12*3 = 36

48+36 = 48 + 36

Therefore 12(4+3) is your answer

The area of each sector is the amount of space on the sector

The area of a sector is calculated as:

A = (1/2) × r^2θ

For the entire sector, we have:

θ =  π/10

r = 6.625

So, we have:

A = (1/2) × 6.625^2 × π/10

Evaluate the product

A = 6.89

For the double region, we have:

θ =  π/10

r = 6.25

So, we have:

A = Complete sector - (1/2) × r^2θ

A = 6.89 - (1/2) × 6.25^2 × π/10

Evaluate the difference

A = 0.75

For the triple region, we have:

θ =  π/10

R = 4.125

r = 3.75

So, we have:

A = (1/2) × R^2θ - (1/2) × r^2θ

A = (1/2) × 4.125^2 × π/10 - (1/2) × 3.75^2 × π/10

Evaluate the difference

A = 0.46

Hence, the area of the triple region is 0.46
