which graph represents the equation (x-3)^2 + y^2 =16

Answer:

Step-by-step explanation:

Answer:

x={-4,-1,0,3}

Step-by-step explanation:

(x²-3x)√x²+5x+4=0

x(x-3)=0

√x²+5x+4=0

x(x-3)=0

x=0

x-3=0

x=3

√x²+5x+4=0

x²+5x+4=0 (square both sides)

x²+4x+x+4=0

x(x+4)+1(x+4)=0

(x+4)(x+1)=0

x+1=0

x+4=0

x=-1

x=-4

Answer:

there is is

Step-by-step explanation:

x=0 or x=3

Answer:

24 minutes

Step-by-step explanation:

4/5 of an hour is 48 minutes so 48 minutes divided by 2 is 24 minutes

Answer 24 min b c if you have 4/5 of an hour it would be 48 min then half of 48 is 24 minutes

To find the area of a square or a rectangle, you would multiply the value of the length by the value of the width.

length x width = area

1. Measure the length of the paper (the length, in this case, is the longest part of the paper).

2. Measure the width of the paper (the horizontal, shorter part of the paper).

3. Multiply said values together to find the area with your chosen system of units.

However, if you are looking for exclusively the length and/or width, you can use a ruler to find said dimensions.

the person above me is right

Step-by-step explanation:

Answer:

a°+110°=180°[ being linear pair]

a°=180-110

a°=70°

b°=a°=70°[ being base of equilateral triangle]

c+b+a=180[being interior angle of triangle]

c+70+70=180

c+140=180

c=180-140

c=40

Answer:

We have 3 variables to solve for.  We will start by writing two equations in three variables but, with the given information, will eventually have those equations written in 2 variables.  The strategy is to set up equations from the given information and solve the equations simultaneously.  Let's assign variables...

c= #children total

s= #students total

a= #adults total

c+s+a=900.............Eq1, total attendance, given

4c+6s+8a=5600....Eq2, total receipts, given

a=(1/2)(c+s)

 =(1/2)c+(1/2)s.....Eq3, #adults total, given

Let's substitute Eq3 into each Eqs1,2 to get two equations in two variables...

c+s+(½c+½s)=900.........Eq1, substitute for"s"

      1.5c+1.5s=900.......combine like terms

            3c+3s=1800.....Eq4, multiple equation

                                      by 2 to eliminate fraction

4c+6s+8(½c+½s)=5600...Eq2, substitute for "s"

   4c+6s+(4c+4s)=5600...distribute 8

               8c+10s=5600...Eq5, combine like terms

Let's solve newly arrived at Eq4,5 simultaneuously...

    3c+3s=1800......Eq4

  8c+10s=5600......Eq5

-24c-24s=-14400...Eq4 multiplied by (-8)

24c+30s=16800...Eq5 multiplied by 3

------------------------

          6s=2400.....add all terms vertically

        ∴ s=400.......divide both sides by 6

Substitute value back into Eq4, solve for "c"...

      3c+3s=1800...Eq4

3c+3(400)=1800...substitute for"s"

  3c+1200=1800

            3c=600.....subtract 1200, both sides

          ∴ c=200....divide both sides by 3

Substitute values back into Eq3, solve for "a"...

  a=(1/2)(c+s).............Eq3

    =(1/2)(200+400)...substitute for "c,s"

    =(1/2)(600)

∴ a=300.....................simplify

We now have our three variables solved.  Let's substitute those values back into original Eqs1,2 to check against the problem requirements...

          c+s+a=900.......Eq1

200+400+300=900....substitute for "c,s,a"

               900=900......true, √check

                  4c+6s+8a=5600.....Eq2

4(200)+6(400)+8(300)=5600...substitute for

                                                  "c,s,a"

        800+2400+2400=5600...simplify

                         5600=5600......true, √check

So our calculated values are correct. Always check your solutions and work!

In summary, we have...

200 children, 400 students, and 300 adults in attendance at the theater for the screening.

Step-by-step explanation:

There were total 150 childrens, 450 students and 300 adults.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is a theater that has a seating capacity of 900 and charges $2.50 for children, $4 for students, and $5.50 for adults. At a certain screening with full attendance, there were half as many adults as children and students combined. The total money brought in was $3825.

Assume that there were [x] childrens, [y] students and [z] adults. Then, we can write the equations as -

x + y + (1/2)(x + y) = 900

2.5x + 4y + (5.5)(1/2)(x + y) = 3825

Plot the graph. We will get x = 150 and y = 450.

Then -

z = (1/2)(150 + 450) = (1/2)(600) = 300

Therefore, there were total 150 childrens, 450 students and 300 adults.

The quotient and remainder, written as partial fractions will be [tex]4x-1 - \frac{2}{x +1} - \frac{3}{(x +2)^2}[/tex].

Quotients are the number that is obtained by dividing one number by another number.

The degree of the numerator is the same as the degree of the denominator, this fraction needs to be simplified.

The rational expression is

[tex]\frac{4x^{3} +11x^{2} -9}{x^{2} +3x+2}[/tex]

Now, the denominator needs to be factored in to split up the second part of the simplified expression into two different partial fractions.

x^2 + 3 x + 2

( x + 1) (x + 2)

The general form of partial fractions.

[tex]A + \frac{B}{x +a} + \frac{C}{(x +a)^2}[/tex]

This gives us,

[tex]4x-1 - \frac{2}{x +1} - \frac{3}{(x +2)^2}[/tex]

Answer:

B

Step-by-step explanation:

Since the y-intercept is (0,3), the second part of the equation of slope (y = mx+b) will be +3. There are three ways to find the slope. Just look at the graph and see how much y increases for every time x increases is the first way. Another way is to find two points that have WHOLE numbers. now count the distance of y between them and the distance of x between them. Now put y over x (y/x). The last way is y1-y2/x1-x2, where you choose to straight points and subtract the y from the other y and the x from the other x, then put y over x. Now we can put the whole equation together to get y = 3/2x +3. or y = 1 and 1/2x+3 (its usually an improper fraction though). Hope this wasn't confusing and helped.

Answer:

Yes.

Step-by-step explanation:

A function is a set of relations without repetitive domains.

From the given relation, there are no repetitive domains. Thus our relation here is a function.

Example of Function

{(1,1), (2,2), (3,3), (4,4), (5,5)}

Example of Non-Function

{(1,1), (1,2), (2,3), (3,4), (4,5)}

From this relation, there are two repetitive domains which are 1's. Thus not making the relation a function.

Answer: 200

Step-by-step explanation:

Number of numbers counted by Alex;

= 2,400 / 6

= 400

Number of numbers counted by Matthew;

= 2,400/4

= 600

Numbers that both of them counted = 600 - 400

= 200
