Answer:

5

Step-by-step explanation:

15-5(p-6)

when p=8,

=15-5(8-6)

=15-5(2)

=15-10

=5

Answer:20

Step-by-step explanation: Do 15-5=10 then plug in 8 as p then subtract 8 from 6which is 2 .Lastly times 10 by 2 which gives you 20.

I hope it helps :)

Answer:

The answer is A.

Step-by-step explanation:

In order to simplify, you have to collect like terms :

x² - 3xy - 5xy - 7y² + 4x² + 8y²

= (x² + 4x²) + (-3xy - 5xy) + (-7y² + 8y²)

= 5x² - 8xy + y²

Answer: Number of photos: 15,25,35,40,50

Time: 3,5,7,8,10

Step-by-step explanation:

To find the time we divide the number of photos by 5. To find the number of photos we multiply the time by 5.when the number of photos is 35, the time is 35 divided by 5 which equals 7 minutes.

Answer:

The only one that works is 48:30

Step-by-step explanation:

You can't divide 24 by anything to get 16, nor 15 to get 10

5:3 means 15 was divided by 3, 24 divided by 3 is 8

Answer:

option d.

{(1,3),(4,2),(2,0),(3,4)}

Answer:

C (0.9)

Step-by-step explanation:

Key skills needed: Solving one variable equations

1) we have the equation --> 12.72 = 5.52 + 8x

2) We need to solve for x.

To get x by itself, we subtract 5.52 from  both sides.  (12.72 - 5.52 = 7.2)

This means 8x = 7.2

3) Divide by 8 from both sides, and you will get x = 0.9 (7.2/8 = 0.9)

Answer:

solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]

Step-by-step explanation:

We need to solve the inequality [tex]-31>x-48[/tex]

Solving the inequality and finding value of x:

[tex]-31>x-48[/tex]

First we will be switching sides i.e. left hand side will become right hand side and right hand side will become left hand side.  In doing so, the inequality sign i.e. > will be reversed and changed with <

[tex]x-48<-31[/tex]

Now, for finding value of x, we will be adding 48 on both sides

[tex]x-48+48<-31+48\\x<17[/tex]

The value of x is less than 17 i.e. [tex]\mathbf{x<17}[/tex]

So, solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]

Answer:

B. 40, 51.5, 88.5

Step-by-step explanation:

(5x - 4) + (2x + 3) + (3x- 4) = 180

10x - 5 = 180

10x = 185

x= 18.5

Substitute

5(18.5) - 4 = 88.5

2(18.5) + 3 = 40

3(18.5) - 4 = 51.5

Answer:

The pythagorean theorem would be the most helpful.

To solve this problem:

[tex]x^2 + 8^2 = 15^2\\x^2 + 64 = 225\\x^2 = 161\\x = \sqrt{161}[/tex]

Answer:

Pythagorean Theorem

Step-by-step explanation:

You want to use Pythagorean Theorem on right degree triangles. Using the formula:

a^2 + b^2= c^2, where a and b are the legs while c is the hypontuse( the slanted side of the triangle and the longest.) let plug in the numbers.

8^2+ x^2=15^2; Subsitution

64+x^2=225: Equalvelent Equation

x^2= 161: Subtraction Poperty of Equality

sqr root of 161= 12.688 or 12.69 or 12.7

x=12.689 ( if rounded to nearest hundredth) or x=12.7 if rounded to nearest tenth.

[tex]\sqrt{161}[/tex]

Answer:

y=-¾x-15/2

Step-by-step explanation:

y--9=-¾(x-2)

y+9=-¾(x-2)

4y+36=-3x+6

4y=-3x+6-36

4y=-3x-30

y=-¾x-15/2

Answer:

The equation of the function in vertex form is represented by [tex]y = -2\cdot (x-6)^{2}+2[/tex].

Step-by-step explanation:

Let [tex](h,k) = (6,2)[/tex] and [tex](x,y) = (0, - 70)[/tex], now we substitute on the equation of the quadratic function and solve for [tex]a[/tex]:

[tex]y = a\cdot (x-h)^{2}+k[/tex]

[tex]-70 = a\cdot (0-6)^{2}+2[/tex]

[tex]-70 = 36\cdot a + 2[/tex]

[tex]36\cdot a = -72[/tex]

[tex]a = -2[/tex]

Therefore, the equation of the function in vertex form is represented by [tex]y = -2\cdot (x-6)^{2}+2[/tex].

Answer:

[tex]\huge\boxed{\tt{x = -5 , y = 2}}[/tex]

Step-by-step explanation:

x = y - 7   ---------------------(1)

-y - 2x = 8 --------------------(2)

Put Equation (1) into (2)

- y - 2 ( y-7 ) = 8

-y - 2y + 14 = 8

-3y = 8 - 14

-3y = -6

Divide -3 to both sides

y = -6 / -3

y = 2

Put y = 2 in (1)

x = 2 - 7

x = -5

So,

x = -5 , y = 2

Answer:

24π in³/75.36 in³

Step-by-step explanation:

We are looking for the volume of a cone with a diameter of 6 inches and a height of 8 inches.

First, divide the diameter by 2 to get the radius.

6 in/2 = 3-in. radius

Now, incorporate the formula for the volume of a cone. That is πr²h/3.

3.14 * 3² * 8/3

Square 3 to get 9.

3.14 * 9 * 8/3

Multiply 3.14 by 9 to get 28.26.

28.26 * 8/3

I recommend turning 28.26 into a improper fraction. That would be 1413/50.

1413/50 * 8/3

Can any cross-cancellation be done? Yes!

50 and 8 share a GCF of 2.

1413/25 * 4/3

1413 and 3 share a GCF of 3.

471/25 * 4/1

Multiply 471 by 4, and put it over 25.

Simplify your answer.

75 9/25 = 75.36 in³, which is about 24π in³.
