Answer:
B
Step-by-step explanation:
A function can not have the same x-values but can have the same y-values. Because option B uses 0 as its x-value more than once, option B does not represent a function.

3(6x+8)=24+18x what the answer
Answer:
0=0 or as known as infinite solution
Step-by-step explanation:
when answering a type of question there are 3 steps
1) Distribute: 3(6x+8)=24+18x
3 x 6x= 18x 3 x 8= 24
18x +24 = 24 + 18x
2) Subtract 24 from both sides of the equation:
18x + 24 = 24 + 18x
-24 -24
18x + 0 = 0 + 18x
3) Subtract 18x from both sides to set apart (x) : 18x = 18x
-18x -18x = 0 = 0

Since the given number has repeating decimals so, it is an irrational number.
(2)
π
Since π also an irrational number, because it value, is nonterminating and repeating.
Thus, the required solution is as follows,
(1) the given number is an irrational number. Option D is correct.
(2) π is an irrational number. Option D is correct.

On a coordinate plane, the orange K is shifted to form the purple K, reflected across the x-axis to form the green k, and rotated to form the black k. Which image is a reflection of the orange letter K in Quadrant I?
Answer:
the green kin quadrant IV
Step-by-step explanation:
i took the quiz and got it right
Point k is reflected across the y-axis to create point k'.
What is reflection?A reflection in mathematics is a mapping from a Euclidean space to itself that is an isometry with a set of fixed points known as the hyperplane, also known as the axis or plane of reflection.
The mirror image of a figure in the axis or plane of reflection is the image produced by a reflection.
From the graph, we can see that point k has a negative x-coordinate, so option A is wrong. Also, point K is located in quadrant II, not in quadrant IV
Point K is not reflected across the x-axis to create K'. For reflection across the x-axis to occur, the point (x,y) across the x-axis will change to (x, -y).
Point K is reflected across the y-axis to create point K'. We can see from the graph that the reflection of the point (x,y) across the y-axis is the point (-x, y)

Emily has 6 gallons of water josh has 23 quarts of water. How many more points does Emily have more than josh
Answer:
2 pints
Step-by-step explanation:
To determine the amount of pints that Emily has more than Josh, gallons and quarts have to be converted to pints and the value is then subtracted
1. Convert gallons and quarts to pints
1 gallon = 8 pints
6 gallons = 8 x 6 = 48 pints
1 quart = 2 pints
23 quarts = 2 x 23 = 46 pints
2. Determine the difference in the amount of pints Emily has and the amount Josh has
48 pints - 46 pints = 2 pints

In many cities, when someone doesn't pay off an entire fine, the city will add a monthly fee until they do. Watch the video from Last week tonight with john Oliver. Then, imagine Ali gets a $150 ticket for speeding. This time, though, the city adds a $35 fee every month until the ticket is fully paid. Use the table and graph to show what the fine will be, and how much Ali will have saved, after each month. How long will it take to pay off the ticket, and how much will it end up costing in total?
Information : Ali makes $50 in savings a month. Also i need the months of the fee and ali to go up to 12 months. thank youuu

Find measure of angle PQS
Answer:
ANGLE PQS = 45°Step-by-step explanation:
angle SRT = 180 - 70 = 110
thus angle QSR = 180 - 20 - 110 = 50
BY Angle sum property
angle PQS = 180 - 85 - 50 = 180 - 135 = 45
