What is the slope of the line that passes through these two points (8, 4) and (5, 3)?

Answers

Answer:

Equation for the slope of the line is, m=y2−y1x2−x1

∵ the point B(5, 8) is above A(3, 4), hence, and B(x2,y2),∵ the point B(5, 8) is above A(3, 4), hence, 

A(x1,y1)→A(3,4) and B(x2,y2)→B(5,8)A(x1,y1)→A(3,4) and B(x2,y2)→B(5,8)

m=8−45−3=2⇒m=8−45−3=2

The slope is the intensity of inclination thus the slope of the line that passes through points (8, 4) and (5, 3) is 1/3.

What is the slope?

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope of a line that passes through (x₁, y₁) and (x₂, y₂) is,

Slope = (y₂ - y₁)/(x₂ - x₁)

Since, the given line is passing through (8, 4) and (5, 3).

Slope = (3 - 4)/(5 - 8)

Slope = -1/-3 = 1/3

Hence "The slope is the intensity of inclination thus the slope of the line that passes through points (8, 4) and (5, 3) is 1/3".

if a square has an area of 324 ft what is the length of each side

Answers

Answer:

Step-by-step explanation:

324/2 because a square has sides that are all equal, so the area is 2 times the length of a side

Step-by-step explanation:

area = L²    where area = 324 ft²

324 = L²

L = √324

Tickets for the school play cost $7 each. Each member of the cast gets 1 free ticket for a family member. For the run of the play, 210 tickets are collected, including all the free tickets, and the box office makes $1,358 from ticket sales. The equation that models this situation is7(210 – c) = 1,358 where c is the number of cast members. How many cast members are in the play?

Answers

Answer:

there are 16 cast members.

Step-by-step explanation:

7(210-c)=1358 multiply everything in the parentheses by 7

1470-cx=1358

-7c=-112 subtract 1470 from both sides

c=16 divide -112 by -7

c=16

Answer:

75 adult tickets125 child tickets

Step-by-step explanation:

Let 'a' represent the number of adult tickets sold. Then (200-a) is the number of child tickets sold, and the revenue is ...

  8a +5(200 -a) = 1225

  3a = 225 . . . . . . . . . . subtract 1000, simplify

  a = 75 . . . . . . . . . . . . .divide by 3

  200 -a = 125

75 adult ($8) and 125 child ($5) tickets were sold.

Step-by-step explanation:

For those who are good with equations....(unlike me when it comes to this)

Answers

Answer:

a = 5

Step-by-step explanation:

When the coefficients of the variables are equal with different constants, then you will get an equation which is never true.

For this particular equation, when a on the right side has a coefficient of 5, you will get the equation: 4(a - 2) + a = 5a - 4.

When you distribute the factors in the parenthesis and add the like terms of a together, 4(a - 2) + a will become 5a - 8. This is because 4(a - 2) + a = 4(a) + 4(-2) + a = 4a - 8 + a = 5a - 8.

Now when you simplify 5a - 8 = 5a - 4 by subtracting 5a from both sides, you will get an equation with unlike constants. For instance 1 = 0.

Now:

5a - 8 = 5a - 4

-5a -5a

-8 = -4

This is never true, so therefore, there is no solution.

Answer:

It is 5

Step-by-step explanation:

Solve the following equation.
150 - x - 2x = 120 +2x

Answers

Answer:

X = 6

Step-by-step explanation:

150 - 3x = 120 + 2x

150 = 120 + 5x

30 = 5x

6 = x

x = 6

The solution to the equation is x = 6.

To solve this equation 150 - x - 2x = 120 +2x , we need to isolate the variable x.

To simplify the equation ;

Distribute the negative sign to the terms inside the parentheses:

150 - x - 2x = 120 + 2x

150 - 3x = 120 + 2x

Combine like terms on both sides of the equation:

-3x - 2x = 120 - 150

-5x = -30

Divide both sides of the equation by -5 to solve for x:

-5x / -5 = -30 / -5

x = 6

Therefore, the solution to the equation is x = 6.
