Solve x – 2y = 12 if the domain is {–3, –1, 0, 2, 5}.
Answers
Answer:
Step-by-step explanation:
Answer:
answer is below
Step-by-step explanation:
x - 2y = 12
First step is to solve for y, so
[tex]x - 2y = 12[/tex]
Then, subtract x on both sides to isolate the variable, y.
[tex]-2y = -x + 12[/tex]
Divide both sides by -2
[tex]y = \frac{1}{2}x - 6[/tex]
------------------------------------------------------------------------------------------------------
The domain is {-3,-1,0,2,5}
Domain is the set of x values
Range is the set of y values
We are given the domain x, we need to find out the y values using the equation: [tex]y= \frac{1}{2}x - 6[/tex]
[tex]y = \frac{1}{2}(-3) -6 = \frac{-15}{2} = -7.5\\\\y = \frac{1}{2}(-1) -6 = \frac{-13}{2} = -6.5\\\\y = \frac{1}{2}(0) -6 = -6\\\\y = \frac{1}{2}(2) -6 = -5\\\\\\y = \frac{1}{2}(5) -6 = -\frac{7}{2} = - 3.5[/tex]
therefore,
when x is -3: y = -7.5
when x is -1: y = -6.5
when x is 0: y = -6
when x is 2: y = -5
when x is 5: y = -3.5
Range is {-7.5, -6.5, -6 , -5, -3.5}
hope this helps and is right :)

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:
48
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

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
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

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
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.

What is an Absolute value function?An absolute value function is a function that gives positive value for a number or variable. It has a V shaped graph, it is also called as a modulus function.
The absolute function is y = | -x +7| +-4
The v shaped curve has a vertex and it can be determined by following method.
The value of the x coordinate is determined by equating the modulus to 0, the point at which the modulus is zero.
-x +7 = 0
Adding -7 to both sides.
-x = -7
x = 7
The value of y at this point is the y coordinate of the vertex.
y = 0 +4
y = 4
(x,y) = ( 7,4)
