[tex] \frac{1}{2} [/tex]

Answer:

The correct answer is 5 11/12

Step-by-step explanation:

HAVE A GOOD DAY!

Answer:

no its not

Step-by-step explanation:

x-11 is only supposed to have one y.

if its a funtion then x should only have one line comming out of it. if its not a finction then x has two lines coming out of it.

Answer: no because the x axis dont equal or match up with the y axis and because theres not a certain amount of numbers for it to equal to or match to.

Step-by-step explanation:

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.            please give me brainliest

Answer:

The equation of the second line is;

y = 4x - 27

Step-by-step explanation:

Firstly, we need the slope of the first line

To get the slope, we need the equation in the general form of ;

y = mx + c

where m is the slope of the line

Thus, we have in this case, to divide through by -5

That will give the slope value as -5/20 = -1/4

If two lines are perpendicular, the product of their slopes is -1

The slope of the line we want to calculate, let us call it m

m * -1/4 = -1

-m = -4

m = 4

So we want to write the equation of a line with slope 4 and point (8,5)

We proceed to use the point-slope form

That will be;

y-y1 = m(x-x1)

y-5 = 4(x-8)

y-5 = 4x-32

y = 4x -32 + 5

y = 4x -27

Answer:

[tex]y=24,[/tex] when [tex]x=1[/tex].

Step-by-step explanation:

Given: [tex]y=4x+20[/tex]

To find: Value of [tex]y[/tex], substituting the known value of [tex]x[/tex]

We have,

[tex]y=4x+20 ...(i)[/tex]

Putting [tex]x=1[/tex] in equation [tex](i)[/tex], we get

[tex]y=4(1)+20[/tex]

[tex]\implies y=4+20[/tex]

[tex]\implies y=24[/tex]  

Hence, the value of [tex]y[/tex] is [tex]24[/tex], when the value of [tex]x[/tex] is [tex]1[/tex].

Answer:

First, you did not exactly state what the original price was or maybe that's how the question is worded, but in this scenario the original price of the freezer would be x because they did not tell us.

Step-by-step explanation:

A 20 percent discount is 0.20 in decimal format. For example if the original price was $20, then you would multiply 0.2 by $20 to get $4.00. In this question i would say the original price would be x, so then it would be 0.2x.

Hope this helps:)

Answer:

  (b)  38.5

Step-by-step explanation:

The polygon is a trapezoid with bases 4 and 7 and height 7. Its area is given by the formula ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(4 +7)(7) = 77/2

  A = 38.5 . . . . square units

Give the other person brainiest pls because they were right I know because I took test and they helped me :)

Answer:

Step-by-step explanation:

a + c = 17 + 7 = 24.

a - 2c = 17 - 2(7) = 3.

Answer:

a. p=421−376/376

Step-by-step explanation:

Computation for Which equation shows how to find the percent increase

Percentage increase=421-376/376*100

Percentage increase=45/376*100

Percentage increase=11.968%

Percentage increase=11.97% (Approximately)

Based on the above calculation The equation that will shows how to find the percent increase of the town's population of children from 376-421 during the past year will be:p=421-376/376

Answer:

Distance between New Delhi and Kota = 388 kilometers

Step-by-step explanation:

Given that:

Average speed of express train = 97 kilometer per hour

Time taken to travel  = 4 hours

Distance between New Delhi and Kota = Speed * Time

Distance = 97 * 4

Distance = 388 kilometers

Hence,

Distance between New Delhi and Kota = 388 kilometers

Answer:

The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.

Step-by-step explanation:

Given that:

An airplane travels 5040 kilometers in 6 hours against the wind

An airplane travels 6000 kilometers in 5 hours with the wind

Let,

x be the speed of plane in still air

y be the rate of wind

Combined speed against the wind = x - y

Combined speed with the wind = x+y

Speed = [tex]\frac{Distance}{Time}[/tex]

x-y= [tex]\frac{5040}{6} = 840[/tex]

x - y = 840    Eqn 1

x + y = [tex]\frac{6000}{5} = 1200[/tex]    Eqn 2

Adding Eqn 1 and 2

x+y+x-y=1200+840

2x=2040

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{2040}{x}\\x=1020[/tex]

Putting x=1020 in Eqn 2

1020+y=1200

y=1200-1020

y=180

Hence,

The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.
