Tell whether the set of ordered pairs {(1, 6), (2, 9), (3, 12), (4, 15)} satisfies a linear function. Explain.
All the points lie on the line. Then each point will satisfy the linear function y = 3x + 3.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The set of ordered pairs {(1, 6), (2, 9), (3, 12), (4, 15)} are given.
Then the equation of the line passing through (1, 6) and (4, 15). Then we have
(y - 6) = [(15 - 6) / (4 - 1)](x - 1)
y = 3x + 3
All the points lie on the line. Then each point will satisfy the linear function y = 3x + 3.
The graph is mentioned below.

Determine The number of solutions 3(x-4)=2x+6
Answer:
The answer will be listed below.
Step-by-step explanation:
First of all, you want x to by itself, so distribute the three to both x and negative 4 so you'll get 3x-12=2x+6.
Now, subtract 2x from both sides and add 12 to both sides and you'll get an answer of x=19. From that, you are able conclude that this equation has one solution.
4x + 2y = 6
x-y=3
What’s the value of the x variable in this solution?
Hello!
[tex]\large\boxed{x = 2}[/tex]
Solve the system using substitution:
We can rearrange the second equation to find an expression for y:
x - y = 3
Subtract x from both sides:
-y = -x + 3
Multiply the equation by -1:
y = x - 3
Substitute this value of y into the first equation:
4x + 2y = 6
4x + 2(x - 3) = 6
Distribute:
4x + 2(x) + 2(-3) = 6
Simplify and combine like terms:
4x + 2x - 6 = 6
6x = 12
6x / 6 = 12 / 6
x = 2.
Answer:
y = -1
Step-by-step explanation:
x - y = 3
x = 3 + y
4x + 2y = 6
substitute x for 3 + y
4(3+y) + 2y = 6
open the parenthesis
12 + 4y + 2y = 6
12 + 6y = 6
subtract 12 from both sides of the equation
12 - 12 + 6y = 6 - 12
6y = 6 - 12
6y = -6
divide both sides of the equation by 6
6y/6 = -6/6
y = -6/6
y = -1

solve: 3/2x -12 = 24
Standard form:
3 /2 x − 36 = 0
Factorization:
3/2 (x − 24) = 0
Solutions:
x = 72 /3 = 24
Answer:
x = 24
Step-by-step explanation:
3/2x -12 = 24 is the given equation. To get the answer we need to get x by itself. This can be done by adding, subtracting, multiplying, and dividing numbers to both sides.
First, let's get rid of -12 by adding it to both sides. This will cancel out the negative 12.
3/2x -12 +12 = 24 +12
our result looks like this:
3/2x = 36
Next, we need to divide x by 3/2. Because it's a fraction, it can also be seen as multiplying by the reciprocal, or flip.
3/2x*2/3 = 36*2/3
the result is x by itself, and therefore the answer
x = 24

find the exact volume of the cylinder
Answer:
87.92 m^3
Step-by-step explanation:
Volume = 3.14r^2*h
r = 1/2 of diameter
h = 7m
Diameter = 4m so r = 2m
Let’s solve
V = 3.14(2)^2*7
V = 87.92 meters cubed.

y = 7x - 16.
y = 2(2x - 5)
What is the solution?
Intro
8 of 10
Answer:
y = 7x - 16:
Slope = 14.000/2.000 = 7.000
x-intercept = 16/7 = 2.28571
y-intercept = -16/1 = -16.00000
y = 2(2x - 5)=
Slope = 8.000/2.000 = 4.000
x-intercept = 10/4 = 5/2 = 2.50000
y-intercept = -10/1 = -10.00000

The number of traffic violations in a city increased from 12 to 16 in a month. What is the percent of increase in the number of traffic violations for that month? Round to the nearest percent, if necessary.
Answer:
33%
Step-by-step explanation:
Percentage increase = [tex]\frac{increase}{initial value}[/tex] x 100%
Number of traffic violations increased from 12 to 16.
Initial value = 12
Final value = 16
increase = Final value - Initial value
= 16 - 12
= 4
Percentage increase = [tex]\frac{increase}{initial value}[/tex] x 100%
= [tex]\frac{4}{12}[/tex] x 100%
= [tex]\frac{1}{3}[/tex] x 100%
= [tex]\frac{100}{3}[/tex]%
= 33.3333%
The percentage increase in the number of traffic violations for the month is 33%.

How many hours until the charges for each company will be equal and what is that charge
Answer:
25 hours, charge= 800
Step-by-step explanation:
300 + 20x = 500 + 12x
8x = 200
x = 25
300 + 20(25)
300+500 = 800
500 + 12(25)
500 + 300 = 800
A bird goes from a lower location to a higher location at a rate of 4 meters per second.
Which equation models the change in the bird's position at 60 seconds?
A. (-60)(-4) = -240
B. 60.4 = 240
C. 60(-4) = -240
D. 60(-4) = 240
Answer:
The answer is C. 60(-4) = -240
Step-by-step explanation:
First, let's eliminate some of the choices. A doesn't make sense since negative times a negative equals positive. Secondly, how can 60.4 equal 240 when 60.4 is less than 240? Furthermore, D doesn't make sense since positive times a negative equals negative.
Here is a rule for you to remember:

Answer:
12a+200=644
Step-by-step explanation:
take the equation and cancel out 200 and do it to both sides
12a+200=644
-200. -200
------------------------
12a=444
then we need to get the variable alone so divide by 12.
12a = 444
---- ----
12. 12
a=37
444 divided by 12 will equal 37
