What is an equation of the line that passes through the points (3,1) and (-3, – 7)?
Put your answer in fully reduced form.

Answers

Answer:

y = 4/3x - 3

Step-by-step explanation:

Use rise over run to find the slope, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(-7 - 1) / (-3 - 3)

-8 / -6

= 4/3

Now, plug in the slope and a point into y = mx + b to get the equation:

y = mx + b

1 = 4/3(3) + b

1 = 4 + b

-3 = b

Plug in the slope and y intercept into the equation:

y = 4/3x - 3

So, the equation is y = 4/3x - 3

Steve is playing a carnival game. He wants to win a prize, but he thinks he has about a 20% chance of winning. He uses the expression 0.2t to calculate the number of games he will need to play in order to win a prize.

If he plays the game 12 times, about how many times can he expect to win?

Answers

Answer:50%

Step-by-step explanation:

Steve's expected times of winning in 12 trials is about 2 times.

What is probability?

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

The winning chance of Steve is 20% or 0.2.

We know, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory.

Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.

Therefore, If he plays the game 12 times the number of times he is expected to win is,

= 12×0.2.

= 2.4 Or 2 times.

A home building company purchases 24 acres of land and divides it into 1/2-acre plots for sale. How many 1/2-acre plots will be for sale?

Answers

Answer:

Step-by-step explanation:

This is a division problem.

You need to divide 24 by 1/2.

24 / 1/2 = 24/1 / 1/2 = 24/1 * 2/1 = 48/1 = 48

Answer: 48

You can also do it this way.

Each acre is the same size as 2 half-acres.

1 acre = 2 half-acres

Multiply both sides of the equation above by 24.

24 * 1 acre = 24 * 2 half-acres

24 acres = 48 half acres

which make an angle 45 degree with x axis in negative direction and passes through a point (- 3, 2)

Answers

9514 1404 393

Answer:

y = -x -1

Step-by-step explanation:

The slope of a line is the tangent of the angle it makes with the x-axis. If you want an angle of -45°, then you need a line with a slope of m = tan(-45°) = -1.

Then the y-intercept is ...

b = y -mx

b = 2 -(-1)(-3) = 2 -3 = -1

So, the slope-intercept equation is ...

y = mx + b

y = -x -1

Choose the equations that have (-3, 5, 3) as a solution. Select the two correct
answers.
-x- y + 5z = 1
x - 2y + 3z = -4
x+y-z= -1
-x+y-z=4
