Answer:

yes!

Step-by-step explanation: im pretty sure it is

Answer:

The question is a Function

Step-by-step explanation:

Because

First, you have to Identify the input and output values.

Then, you have to Check to see if each input value is paired with only one output value. If so, the table represents a function.

Hope it helps out!

Answer:

y=4/5x-1 is the answer (A)

Step-by-step explanation:

Answer: Step-by-step explanation:

the first one would be your answer (y= 4/5x -1)

because the y intercept is -1 and the rise if 4 and run is 5 and that would be your slope.

Answer: A. 81/625

Step-by-step explanation:

From the question, we are informed that there are 4 traffic signals on ones way to work, and there's a 60% chance of making each one, independent of whether or not the previous one is made.

The probability that one will make it to work on time will be to multiply 60% for the 4 period. This will be:

= 60% × 60% × 60% × 60%

= 60/100 × 60/100 × 60/100 × 60/100

= 3/5 × 3/5 × 3/5 × 3/5

= 81/625

Given:

In triangle XYZ, J, K and L are midpoints of the sides.

JK = 38, XZ = 96, YX = 56.

To find:

KL, YZ and LZ.

Solution:

We have, J, K and L are midpoints of the sides of triangle XYZ.

JK = 38, XZ = 96, YX = 56.

Midsegment theorem: If a line segment between the midpoints of two sides of the triangle, then the length of the segment is half of the third side.

Using midsegment theorem, we get

[tex]KL=\dfrac{1}{2}YX[/tex]

[tex]KL=\dfrac{1}{2}(56)[/tex]

[tex]KL=28[/tex]

And,

[tex]JK=\dfrac{1}{2}YZ[/tex]

[tex]38=\dfrac{1}{2}YZ[/tex]

[tex]76=YZ[/tex]

L is the midpoint of the side YZ. So,

[tex]YL=LZ=\dfrac{1}{2}YZ[/tex]

[tex]YL=LZ=\dfrac{1}{2}(76)[/tex]

[tex]YL=LZ=38[/tex]

Therefore, the measures of KL, YZ and LZ are 28, 76 and 38 respectively.

Answer:

  x = -6.25

Step-by-step explanation:

Eliminate parentheses using the distributive property.

  -7 -4x = 18

Add 7 to get the x-term by itself.

  -4x = 25

Divide by the coefficient of x.

  x = 25/-4

  x = -6.25

Answer:

Options (B), (D), (E), (F) and (G)

Step-by-step explanation:

Any equation in the form of 'y = mx' shows the proportional relationship.

Or functions passing through origin show the proportional relationship.

Where 'm' = Proportionality constant

Now by analyzing the given options,

Option A

C = 2p + 6

Not proportional.

Option B

T = 2.5 D

Proportional.

(Proportionality constant = 2.5)

Option C

F = [tex]\frac{9}{5}C+32[/tex]

Not proportional

Option D

C = 2.54n

Proportional.

Option E

E = 2s

Proportional

Option F

S.A. = 6s²

Proportional.

Option G

Volume (V) = s³

Not Proportional.

Options (B), (D), (E), (F) and (G) are the correct options.

Answer:

she would paint 350.4 square feet

Step-by-step explanation:

first you would find the surface area of one of the triangles, then multiple it by 2 because there are 2 triangles. next you would find the area of each individual rectangle. after that you would add up each of the measurements for the triangles and rectangles.

area of a triangle =1/2 base×height

Answer:

D. x =9, angle measure is 27°.

Step-by-step explanation:

3x° = 27° (vertical angles)

x° = 27°/3

x° = 9°

x = 9

3x° = 3*9° = 27°

So, x =9, angle measure is 27°.

Answer:

Step-by-step explanation:

To find;

a) The number of customers that will be there if the bakery charges $10 per pie

b) To determine how much money (revenue) the bakery will make at that price if one customer buys only one pie.

So; given the function:

C(p) = 110 - 4.4 p

where

p = 10

C(10) = 110 - 4.4(10)

C(10) = 110 - 44

C(10) = 66

Thus, when the bakery charges $10, the number of customers is 66.

The revenue now when each customer purchase only one pie is:

= $66 × 10

= $660

Answer:

27

Answer:

b

Step-by-step explanation:

43x+2=64+455−766

Step 1: Simplify both sides of the equation.

43x+2=64+455−766

43x+2=64+455+−766

43x+2=(64+455+−766)(Combine Like Terms)

43x+2=−247

43x+2=−247

Step 2: Subtract 2 from both sides.

43x+2−2=−247−2

43x=−249

Step 3: Divide both sides by 43.

43x /43  =  −249 /43

x =  −249 /43

Answer:

x =  −249 /43

Answer:

x =  −249 /43

Answer:

x=-4,y=-3

Step-by-step explanation:

The paint required to cover 1 door is 5/4 liters.

Step-by-step explanation:

The paint required to cover 1 3/5 doors = 2 liters.

Convert mixed fraction into proper fraction.

Therefore, the paint required to cover 8/5 doors = 2 liters.

The paint required to cover 1 door = x liters.

To find x :

Comparing the given data and the unknown data.

8/5 door / 2 liters = 1 door / x liter

x = 2 × 5/8

x = 10/8

x = 5/4 liters.

The paint required to cover 1 door is 5/4 liters.

Answer:

20x + 18x + 4

Step-by-step explanation:

The quilt was in a 5:4 ratio, which meant the length was 5x and the width was 4x. The larger quilt added a border of 1-inch squares, which meant that the length & width would increase by 2 inches.

We have the area as (5x + 2)(4x + 2) = 20x + 10x + 8x  + 4

                                                             = 20x + 18x + 4

Solution: 20x + 18x + 4
