The next answer on edge is also C. 9a8 + 24a4 + 16

The multiplication of -8x⁵y² and 6x²y will be -48x⁷y³ so option (C) will be correct.

What is multiplication?

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Given the two terms,

-8x⁵y² and 6x²y

If we multiply

-8x⁵y² ×  6x²y = (-8)×6 × x⁵y² × x²y

⇒ - 48 × x⁵x² y²y¹

⇒ - 48 × x⁵⁺²y²⁺¹

⇒ - 48x⁷y³

Hence "The multiplication of -8x⁵y² and 6x²y will be -48x⁷y³".

Answers

Answer:

Roman civilization lasted for 985 years.

Step-by-step explanation:

Given that Roman civilization began in 509 BC and ended in 476 A.

All we have to do is to subtract -579 from 476.

i.e.

[tex]476 - (-509)[/tex]

[tex]=476+509[/tex]

[tex]=985[/tex] years

Thus, Roman civilization lasted for 985 years.

Answer:

Step-by-step explanation:

3×20 is 60, and it works with 5, and it is the smallest possible Multiple

Answer:

60

Step-by-step explanation:

Find the prime factorization of each number:

3 = 3

5 = 5

20 = 2^2 * 5

LCM = product of common factors with greatest exponent and non-common factors.

LCM = 3 * 5 * 2^2 = 15 * 4 = 60

If x = 14, which equation is true?
A.3 ( 20 − x ) = 44
B.3 ( 12 − x ) = 6
C.2 ( x − 3 ) = 22
D.2 x − 3 = 22

Answers

Answer:

C.  2 ( x − 3 ) = 22

Step-by-step explanation:

if x = 14

2 ( x − 3 ) = 22

2 (14 - 3) = 22

2 (11) = 22

22 = 22

therefore, the answer is C.

Write the standard form of the equation of a line with a slope of -4 passing through the point (1, -4).

Select one:
a. -4x - y = 0
b. -x - 4y - 15 = 0
c. x + 4y + 15 = 0
d. 4x + y = 0

Answers

I think the answer is a.

Answer:

Step 1: We must determine the equation of the line in slope-intercept form* by solving for b.

[tex]-4 = -4(1) + b\\\\-4 = -4 + b\\\\0 = b[/tex]

Step 2: Now we write the equation in slope-intercept form.

[tex]y = -4x[/tex]

Step 3: We can now change the above equation to standard form by moving variables to one side.

[tex]y = -4x\\\\4x + y = 0[/tex]

Our answer is D. 4x + y = 0.

*Slope-intercept form: y = mx + b.

Step-by-step explanation:

You would divide it by pie r squared to get h then flip the equation around so it would be

h= v/ pie r squared

Answer:

A) H= V/ π r^2

V = π r^2 H

V = π × r × r × H

V/ π r^2 = H

H = V/π r^2

Where does the graph intersect the y-axis (answer should be an ordered pair)?

Answers

Given:

The equation is

[tex]1.5x+4.5y=18[/tex]

To find:

The y-intercept (in ordered pair).

Solution:

We have,

[tex]1.5x+4.5y=18[/tex]

Putting x=0, we get

[tex]1.5(0)+4.5y=18[/tex]

[tex]0+4.5y=18[/tex]

[tex]4.5y=18[/tex]

Divide both sides by 4.5.

[tex]y=\dfrac{18}{4.5}[/tex]

[tex]y=4[/tex]

So, y-intercept is 4.

Therefore, the graph intersect the y-axis at (0,4).

Totsakan school is selling tickets to a choral performance on the first day of ticket sales the school sold 10 senior tickets and 1 child ticket for a total of $85 the school took in $75 on the second day by selling 5 senior citizens tickets and 7 child tickets find the price of a senior ticket and the price of a child ticket

Answers

Given :

On the first day of ticket sales the school sold 10 senior tickets and 1 child ticket for a total of $85 .

The school took in $75 on the second day by selling 5 senior citizens tickets and 7 child tickets.

To Find :

The price of a senior ticket and the price of a child ticket.

Solution :

Let, price of senior ticket and child ticket is x and y respectively.

Mathematical equation of condition 1 :

10x + y = 85    ...1)

Mathematical equation of condition 2 :

5x + 7y = 75    ...2)

Solving equation 1 and 2, we get :

2(2) - (1)   :

2( 5x + 7y - 75 ) - ( 10x +y - 85 ) = 0

10x + 14y - 150 - 10x - y + 85 = 0

13y = 65

y = 5

10x - 5 = 85

x = 8

Therefore, price of a senior ticket and the price of a child ticket $8 and $5.

Hence, this is the required solution.

The length of a rectangle is three times the width. The perimeter of the rectangle is 72 cm. Find the dimensions of the rectangle.

Answers

Answer: length=27, width 9

Step-by-step explanation: To solve this problem, you should set up an equation. The length is 3x, and the width is x. To find the perimeter of a triangle, you do length times two + width times two. So 6x+2x=72. 8x=72, x=9. Length is 27, width is 9.

Answer:

Length: 27cm

Width: 9cm

Step-by-step explanation:

Since the length of the rectangle is 3 times the width, we can assume the    width=x and the length=3x.

      P=72cm

     Perimeter= 3x+3x+x+x

Set the 2 equations equal to each other

   72=3x+3x+x+x

Solve for x

   72=8x

   9=x

Length=3x

   Length=9(3)

   Length=27

Width=x

   Width=9

   

what is an y-intercept

Answer:

Answer:

What is an y-intercept ?

A y-intercept is in analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x= 0.

Let's start with the second one, 2x+2y=4

Substitute x with -1 -----> 2(-1)+2y=42 times -1 makes -2 so new equation is ---> -2+2y=4Now add 2 on each side to get rid of 2 and get this ----> 2y=6Now divide 6 by 2 to get this ---->  y=3
