Answer:

[tex]\huge{ \boxed{ \sf{No}}}[/tex]

✑ Question :

No , it's not a function.

✎ Reason :

This is not a function because one element 11 of set A is associated to elements 9 and 5 of set B.

♨ Explore about function :

↪ Function is a special type of relation. It is the refinement of relation. In a relation from A to B , every element of set A should have only one ( distinct ) image in B to be a function. In other words , if no two different ordered pairs have the same first component , then it is a function.

Hope I helped!

Have a wonderful day ! ツ

Answer:

Size of V = 95°

Step-by-step explanation:

The total sum of angles in a triangle is 180°

You can find Angles T and V.

2x+3x+5 = 180°-25°

5x+5 = 155°

5x = 155°-5

    = 150°

x = 150°÷5

  = 30°

Angle V = 3×30°+5

             = 95°

Answer:

x = [tex]1,\frac{1}{2}[/tex]

Step-by-step explanation:

[tex]4|4x-3|-8=-4\\[/tex]

Add 8 to both sides;

4|4x - 3| = 4               4|4x - 3| = -4

Divide both sides by 4;

4x - 3 = 1                   4x - 3 = -1

Add 3 to both sides;

4x = 4                       4x = 2

Divide both sides by 4;

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

Answer:

Check below for step-by-step guide.

Step-by-step explanation:

a) Recall the formula for area is length times width. You are given both of those values. Width= (5x+2) and length = (4x-1). All you have to do is multiply them. You will get a quadratic!

b) This is just basically a lot of plugging in to the equation: Volume= length x width x height. So let's look at what we have!

It says our volume is 20x^3 + 63x^2+ 7x-6

It says our width is : (5x+2)

It says out length is (4x-1).

So the volume = l x w x h , we just plug in those numbers I listed above :

20x^3 + 63x^2+ 7x-6= (4x-1) (5x+2) (height)

Now remember you already multiplied length times width in problem (a). You can use that expanded quadratic on the right side. Then subtract values and isolate height!

You asked for an explanation of what to do step by step, so if you actually need help solving it, comment please! :)

Answer:

$4.50

Step-by-step explanation:

$6.75 divided by 1.5 equals $4.50

The price per pound of beef Mrs.Kearns bought is $4.5 per pound.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Mrs.Kearns bought 1.5 pounds of ground beef from Kroger and

she paid a total of $6.75.

Therefore, The cost of per pound can be obtained by dividing the total amount by the total pounds of beef which is,

= 6.75/1.5.

= $4.5 per pound.

Answer:

-8

Step-by-step explanation:

-9 + (-12) - (-13) = -8

Answer:

x = 59/4

Step-by-step explanation:

4x + 9 = 68

Subtract 9 from both sides.

4x + 9 - 9 = 68 - 9

4x = 59

Divide both sides by 4.

4x/4 = 59/4

x = 59/4

Answer:

X=0.75

Step-by-step explanation:

Step 1:

68-9=59

Step 2:

59 divided by 4= 14.75

Step 3:

0.75=3/4

14 3/4=14.75

Solution:

X=0.75

Another way is 59/4=14.75

Answer:

-3x+1y=-1

or

3x-1y=1

or

by multiplying with 1/3 the first equation we get

-1x+1/3y=-1/3

or from second equation

1x-1/3y=1/3

Step-by-step explanation:

y-y1=m(x-x1)

y1=-7

x1=-2

m=3

so

y-(-7)=3(x-(-2))

y+7=3(x+2)

y+7=3x+6

-3x+y=6-7

Answer:

First number: 20

Second number: 30

Step-by-step explanation:

First#:   x

Second#:   y

Constraints:

   x + y = 50      

   1/4x + 2/3y = 25

Isolate variable y:

   x + y = 50    

  -1/4 (x + y = 50 )

 -1/4x - 1/4y = -12.5

  Add equations the two equations to eliminate x:

    -1/4x - 1/4y = -12.5

     1/4x + 2/3y = 25

  _________________

       5/12y = 12.5

           5y = 150

              y = 30

Substitution to find x:

       x + y = 50  

       x + 30 = 50

              x = 20
