Function is a line points (3,2), (5,8), and (8,y) what is y
SashulF [63]
Y = mx + b

(3;\ 2)\to x_1=3;\ y_1=2\\\\(5;\ 8)\to x_2=5;\ y_2=8\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\to m=\dfrac{8-2}{5-3}=\dfrac{6}{2}=3

Therefore we have: y = 3x + b.

Put the coordinates of the point (3; 2) to the equation of the line:

2 = 3\cdot3+b\\2=9+b\ \ \ |-9\\b=-7

Therefore we have: y = 3x - 7

Substitute the coordinates of the point (8; y) to the equation of the line:

y = 3\cdot8-7=24-7=17

Answer: y = 17.

Determine the amount needed such that when it comes time for retirement, an individual can make monthly withdraws in the amount
bazaltina [42]

Answer:

The amount needed such that when it comes time for retirement is $396721.78.

Step-by-step explanation:

Given : An individual can make monthly withdraws in the amount of $2,154 for 30 years from an account paying 5.1% compounded monthly.

To find : The amount needed such that when it comes time for retirement?

Solution :

Using the formula of monthly payment,

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}

Discount factor D=\frac{1-(1+i)^{-n}}{i}  

Where,

Amount = ?

Monthly payment  M=$2154

Rate r= 5.1%=0.051

i=\frac{0.05}{12}=0.00425

Time = 30 years  

n=30\times12=360

Substitute all the values,

D=\frac{1-(1+i)^{-n}}{i}

D=\frac{1-(1+0.00425)^{-360}}{0.00425}

D=\frac{1-(1.00425)^{-360}}{0.00425}

D=\frac{1-0.21723}{0.00425}  

D=\frac{0.78277}{0.00425}

D=\$184.1811

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}

2154=\frac{A}{184.1811}

A=2154\times 184.1811  

A=\$396721.778

Nearest cent, A=\$396721.78

Therefore, the amount needed such that when it comes time for retirement is $396721.78.

Find the value of the variables in the figure below
svetlana [45]

Answer:

The answer to your question is:

x = 21

y = 4

∡ = 75° and 105°

Step-by-step explanation:

Process

            3(x + y)° + 5x = 180                  supplementary angles

            3(x + y) = 4x - 9                        corresponding angles

Expanding

           3x + 3y + 5x = 180       (1)           Like terms

           3x + 3y = 4x - 9            (2)        

          8x + 3 y = 180         (1)

    8   (   -x  + 3 y = -9)       (2)           Multiply by 8

       8x  + 3y = 180       (1)

      -8x +24y = -72        (2)                    Elimitation method

               27 y = 108

                  y = 108 / 27

                  y = 4        

         8x + 3 (4) = 180

         8x +12 = 180

               8x    =  168

              x = 21

             

3(21 + 4) = 3(25) = 75°

5(21) = 105°
