what is the slope of (-3,2) (-5,-2)
what is the slope of (7,1) (1,-7)​

Answers

Answer:

The slope of the points (-3,2) (-5,-2) is 2

The slope of the points (7,1) (1,-7)​ is 4/3

Step-by-step explanation:

Use rise over run (y2 - y1) / (x2 - x1)

Plug in the points given and find the slopes:

(y2 - y1) / (x2 - x1)

(-2 - 2) / (-5 + 3)

-4/-2

= 2

Find the next slope:

(y2 - y1) / (x2 - x1)

(-7 - 1) / (1 - 7)

-8/-6

= 4/3

The slope of the points (-3,2) (-5,-2) is 2

Solve 2х + 4 > 16.
А. x> 6
В. x<10
C. x> 10
D. х< 6

Answers

Answer:

The answer is x > 6.

Reasoning:

2x + 4 > 16You have to subtract 4 from both sides:

2x + 4 > 16

-4 > -4

2x > 12

16 subtract from 4 is 12. You then divide the 12 by the 2.

2x > 12

2 2

x > 6

You then get the result of x > 6.

Which of the following rules represent the function graphted
F(x)=1/2x
F(x)=x
F(X) = x + 2

Answers

Answer: F(x) = x

Step-by-step explanation:

y = mx + b is the base equation

m = the slope slope equals the increase of y over x

b = the y intercept

y = 1/1 x + 0

so y = x

or f(x) = x

F(x) = x

I take two blocks at random. What is the probability that these two blocks have exactly two of these four properties the same?

Answers

Answer: 0.54

Step-by-step explanatio;

We would have three in common out of 4 characteristics (4 out of 4 is not possible). There are 4 possible ways to share 3 out of 4 characteristics.

Denoting the characteristics as {M,C,Si,Sh} so P(B2={1,1,1,0}|B1={1,1,1,0}) is the probability that box 2 shares its first three characteristics with box 1 given that box one has characteristics

We now have

P(B2 has 3 elements in common with B1)=P(B2={1,1,1,0}|B1={1,1,1,0})xP(B1={1,1,1,0})+P(B2={1,1,0,1}|B1={1,1,0,1})xP(B1={1,1,0,1})+P(B2={1,0,1,1}|B1={1,0,1,1})xP(B1={1,0,1,1})+P(B2={0,1,1,1}|B1={0,1,1,1})xP(B1={0,1,1,1})

P(B2 has 3 elements in common with B1)=(4x5x24+3x4x30+2x3x40+1x2x60)1120x119= 0.084

which is close enough to the value from the simulation code (modified to count the number of 3-ties)

Now, I use the same reasoning to compute:

P(B2 has 2 or more elements in common with B1)=(19x20x6+11x12x10+9x10x12+14x15x8+7x8x15+5x6x20)1120x119= 0.54

Equation: (2-1)((3-1)+(4-1)+(5-1)) + (2)((3)+(4)) + (12) = 35 with a total of 119 possibilities.

answer: 35/119

The side length of a cube can be represented by the expression 2x⁵. If the sifr length is doubled, write an expression to represent the new volume of the cube.​

Answers

The area of a rectangular model is 64k²+72.

Given that, the length of a rectangle = 8k+9 units and the width of a rectangle = 8 units.

What is the area of a rectangle?

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Now area of a model is

(8k+9)×8

= 8×8k+8×9

= 64k²+72

Therefore, the area of a rectangular model is 64k²+72.

Complete Question

The Henderson Hawks minor-league baseball team is giving away baseballs an

game. The balls cost $3 each and the towels cost $2 each. The team wants to give away 200 items and have 500 to spend. How many of each item should the team give away Show your

work or explain your reasoning.

Answer:

They should give away 100 balls and 100 towels

Step-by-step explanation:

Let the number of balls = x

Let the number of towels = y

x + y = 200........ Equation 1

y = 200 - x

$3 × x + $2 × y = $5000

3x + 2y = 5000...... Equation 2

3x + 2(200 - x)= 5000

3x + 400 - 2x = 5000

Collect like terms

3x - 2x = 500 - 400

x = 100

Number of balls to be given away = 100

Note:

y = 200 - x

y = 200 - 100

y = 100

Number of towels to be given away = 100

Therefore, they should give away 100 balls and 100 towels
