3y = x - 12
Y= 1/3X -4
parallel, perpendicular or neither
Answer:
PARALLEL
Step-by-step explanation:
The second equation, y = (1/3)x - 4, has already been solved for y. To compare the slopes easily, we need now to solve the first equation for y, obtaining y = (1/3)x - 4.
We see that these two lines have the same slope, m = 1/3, and thus conclude that these lines are PARALLEL.

What is the value of W in a exterior angle theorem
Answer:
26
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.
so:
30 + 2w - 8 = w + 48
22 + 2w = w + 48 export like terms to the same side of the equation
2w - w = 48 - 22 subtract
w = 26

A soccer team is having a car wash. The team spent $50 on supplies. They earned $300, including tips. The team's profit is the amount the team made after paying for supplies. Use a sum of integers to find the team's profit. The team's profit was $
Answer:the answer is $ f(x) = 3x + 50
f(22) = 3(22) + 50
f(22) = 66 + 50
f(22) = 116
So, he will make $116.
As an ordered pair, the solution is (22, 116).Step-by-step explanation:
Profit =Money left after supplies

Let C be the event that a randomly chosen person went to college. Let J be the event that a randomly chosen person has a job. Identify the answer which expresses the following with correct notation: Given that the person went to college, the probability that a randomly chosen person has a job.
The probability of event J, followed by event C is occurred is P( J | C)
What is probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
Experiment: A trial or procedure carried out to generate a result is referred to as an experiment.Sample Space: A sample space is the collection of all potential results of an experiment. Tossing a coin, for instance, has two possible outcomes: head or tail.Favorable Consequence: An occurrence is deemed to have generated the desired outcome or an anticipated event if it did so.Trial: To conduct a trial is to conduct a random experiment.The given case is case of Conditional Probability.
As, the probability of random chosen person has a job 'j' followed by the person went to the college 'c'

9. A nonstop bus ride from the bus station in Atlantic City, New Jersey, to the bus station in Albany, New York,
took 6 hours. If the average speed of the bus was 21 meters per second, what is the distance between the two
bus stations, to the nearest kilometer?
a.756 kilometers
b. 126 kilometers
c. 454 kilometers
d. 350 kilometers
Answer:
C
Step-by-step explanation:
EASY IVE DONE IT
Using conversion of units and the relationship between velocity, distance and time, it is found that the distance between the two stations is of:
c. 454 kilometers
Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
In this problem:
Time of 6 hours, hence [tex]t = 6[/tex].Velocity of 21 m/s. To convert from m/s to km/h, we multiply by 3.6, hence [tex]v = 21(3.6) = 75.6[/tex]Then, solving for the distance:
[tex]v = \frac{d}{t}[/tex]
[tex]75.6 = \frac{d}{6}[/tex]
[tex]d = 6(75.6)[/tex]
[tex]d = 453.6[/tex
Rounding up, 454 km, option c.

What is the solution to 8x minus 3(2x minus 4) = 3(x minus 6)
Answer:
x = 30.
Step-by-step explanation:
8x - 3(2x - 4) = 3(x - 6)
8x - 3*2x + - 3*-4 = 3*x + 3 * -6
8x - 6x + 12 = 3x - 18
2x + 12 = 3x - 18
2x - 3x + 12 = 3x - 3x - 18
-x + 12 = -18
-x + 12 - 12 = -18 - 12
-x = -33
-x/-1 = -30/-1
x = 30.
Answer:
[tex]x=30[/tex]
Step-by-step explanation:
[tex]8x-3\left(2x-4\right)=3\left(x-6\right)[/tex]
First, we will expand [tex]-3\left(2x-4\right)[/tex] by applying the distributive property:
[tex]-3\times \:2x-\left(-3\right)\times \:4[/tex]
** [tex]-\left(-a\right)=a[/tex]
[tex]-6x+12[/tex]
[tex]8x-6x+12=3\left(x-6\right)[/tex]
Expand, [tex]3\left(x-6\right):[/tex]
[tex]3x-3\times \:6[/tex]
[tex]3x-18[/tex]
[tex]2x+12=3x-18[/tex]
Subtract 12 from both sides:
[tex]2x+12-12=3x-18-12[/tex]
[tex]2x=3x-30[/tex]
Subtract 3x from both sides:
[tex]2x-3x=3x-30-3x[/tex]
[tex]-x=-30[/tex]
Divide both sides by -1:
[tex]\frac{-x}{-1}=\frac{-30}{-1}[/tex]
[tex]x=30[/tex]
