Which of the following functions are linear?
Function A
x 3 6 9 12 15
y 9 36 81 144 225
Function B
x 5 10 15 20 25
y 8 16 24 32 40
A. Function A
B. Function B
C. Function A and Function B
D. None of the above
Answer:
answer B is the right answer.
Step-by-step explanation:
Function A has the form of y = x² , which is NOT linear but quadratic.
Function B has the form of y = 8/5x which is linear.
So answer B is the right answer .
The function which is linear is Function B which is f ( x ) = ( 8/5 )x
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
Function B
x 5 10 15 20 25
y 8 16 24 32 40
So , for every increase of 5 in x, y increases by 8, which can be written as the equation y = (8/5)x.
f ( x ) = ( 8/5 )x
Hence , the linear function is f ( x ) = ( 8/5 )x

Pablo guarda en su cajon 2 pares de medias blancas 4 pares de medias de azules y tres pares de medias negras cual es la probabilidad de que saque medias un par azul si saca las medias sin ver
Answer:
44.4%
Step-by-step explanation:
The probability in this case would be the specific number of pairs of means that we are asked to calculate, that is, blue divided by the total number of pairs, which would be the sum of the different colors, then:
We have that blue there are 4 pairs, and in total it would be 2 + 4 + 3 = 9, that is to say 9 pairs of means.
therefore the probability is:
4/9 = 0.444
Which means that there is a 44.4% chance of drawing a blue pair.
A trumpet player is currently standing in position (3, 2) on a gridded football field. Her bandleader
instructs her to move two units to the left and one unit up. What are her new coordinates?
The trumpet player's new coordinates are
Answer:
(1, 3)
Step-by-step explanation:
Current position (3,2)
Moving left of the x axis results in a decrease, so: 3 - 2 (As she is moving 2 units to the left)
Moving up results in a positive increase on the y axis, so: 2 + 1 (As she is moving one unit up)

What is the equation of a line that passes thorough the point (9,-3) and is parallel yo the line whose equation is 2x-3y=6?
Answer:
y+3=2/3(x-9)
Step-by-step explanation:
2x-3y=6
-3y=-2x+6
y=2/3x-2
This means that any line parallel to it must have a slope of 2/3 as well. Therefore, the equation of this line, in point slope form, is:
y+3=2/3(x-9)
Hope this helps!
Answer:
y = 2/3 - 9
Step-by-step explanation:
1. rearrange the equation
-3y = -2x + 6
y = 2/3 - 2
2. because it is parallel, the gradient will be the same. substitute into y - y1 = m(x-x1)
y - (-3) = 2/3 (x - 9)
y + 3 = 2/3 - 6
y = 2/3 - 9
Circle J is inscribed in isosceles trapezoid ABCD, as shown. Points E, F, G, and H are points of tangency. The length of AB is 10 cm. The length of DC is 20 cm. What is the length, in cm, of BC?
Answer:
15cm
Step-by-step explanation:
Theorem: All tangents to a circle from the same point are equal.
Sine E, F, G and H are points of Tangency, by the theorem above:
EB=BFFC=GCThe diameter line EC divides the Isosceles Trapezoid into two equal parts.
Therefore:
EB=10/2=5cmGC=20/2=10cmWe then have by the equality above that:
BF=5cmFC=10cmBC=BF+FC
=5+10
=15cm

PLS HELP!!!!! WILL MARK BRAINLIEST Jake is moving. He rented the following moving truck. All the boxes that he has are the same size. He wants to determine the maximum number of cube shaped boxes he can fit in the moving truck. Show all calculations and label all work.
Answer:
He can fit 53 boxes in the moving truck.
Step-by-step explanation:
Dimensions of the container of truck = 15 feet × 7.5 feet × 7.5 feet
The volume of the container of moving truck = Length × width × height
= 15 × 7.5 × 7.5
= 843.75 feet³
Sides of each small square box = 2.50 feet
Volume of the one box = 2.5 × 2.5 × 2.5
= 15.63 feet ³
Maximum number of cube shaped boxes he can fit in the moving truck
= [tex]\frac{843.75}{15.63}[/tex]
= 53.98
He can fit 53 boxes in the moving truck.

Given the figure below, find the values of x and z.
Answer: x = 2 and z=78
Step-by-step explanation:
Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure). Z is Opposite to 78 angle, so z=78.
Adjacent angles add up to 180 degrees, and 78 and (5x + 92) are adyacents so:
5x + 92 + 78 = 180
5x + 170 = 180
5x = 180 - 170
5x = 10
x = 10/5
x = 2

The sum of the numerator and the denominator of the certain fraction is equal to 4,140. When the fraction was reduced, the result was 7 13 . What was the original fraction?
Answer:
1449/2691
Step-by-step explanation:
We must start from the fraction that is 7/13. Now, we know that it was simplified, with trial and error we can reach the result.
First, let's multiply both by 200:
7 * 200 = 1400
13 * 200 = 2600
1400 + 2600 = 4000
It means that we are missing 140, to reach the objective, that is, we are close, let's try 205 now:
7 * 205 = 1435
13 * 205 = 2665
1435 + 2665 = 4100
We get even closer, only 40 missing, let's try 207 below:
7 * 205 = 1449
13 * 205 = 2691
1449 + 2691 = 4140
We managed to get to the corresponding numbers, therefore the original fraction was 1449/2691
