Refer to the equation x - 5y = 20.
(a) Create a table of values for at least 4 points. Show your work.
(b) Use the table of values to graph the line.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the equation :

X - 5y = 20

x - 20 = 5y

(x - 20) / 5 = y

x = - 5

y = (-5 - 20) / 5 = -5

x = 0

y = (0 - 20) / 5 = - 4

x = 5

y = (5 - 20) / 5 = - 3

x = 10

y = (10 - 20) / 5 = - 2

X : _____ - 5 ___ 0 ____ 5 ____10

y : _____ - 5 ___- 4 ___ - 3 ___ - 2

The missing number in the series 9,_, 6561,43046721 is

Answers

Answer:

The missing number in the series 9,_, 6561,43046721 is

Step-by-step explanation:

The phone company NextFell has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 260 minutes, the monthly cost will be $114. If the customer uses 640 minutes, the monthly cost will be $247.


A) Find an equation in the form y= mx+b, where x is the number of monthly minutes used y is the total monthly cost of the NextFell plan.


Answer: _____



B) Use your equation to find the total monthly cost if 949 minutes are used.


Answer: If 949 minutes are used, the total cost will be _____ dollars.

Answers

Answer:

Explained below.

Step-by-step explanation:

(A)

Use two-point form to determine the equation for the total monthly cost of the NextFell plan.

[tex](y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\cdot (x -x_{1})\\\\(y-247)=\frac{247-114}{640-260}\cdot (x-640)\\\\(y-247)=0.35x-224\\\\y=0.35x+23[/tex]

(B)

Compute the total monthly cost if 949 minutes are used as follows:

[tex]y=0.35x+23\\\\=(0.35\times 949)+23\\\\=355.15[/tex]

Thus. the total monthly cost if 949 minutes are used is $355.15.

Answer:

∠AMC  = 75

Step-by-step explanation:

ΔABC,

∠C = 90°  ; ∠B = 30°

∠A + ∠B +∠C  = 180   {Angle sum property of triangle}

∠A + 30 + 90 = 180

       ∠A + 120 = 180

                 ∠A = 180 - 120

                 ∠A  = 60°

In ΔACM,

∠ACM = 90/2  =  45°         { CM is angle bisector}

∠ACM + ∠AMC +∠A =  180   {angle sum property}

   45 +  ∠AMC + 60 = 180

            ∠AMC + 105 = 180

                     ∠AMC = 180 - 105

∠AMC  = 75

Mountain climber Joe climbed to a mountain peak that was1200 feet above its base and 1500 feet east of its base. Mountain climber Bob climbed to a mountain peak that was 900 feet above its base and 1000 feet east of its base.

Who climbed a steeper mountain? Explain.

Answers

Answer:

Mountain climber Joe climbed the steepest mountain

Step-by-step explanation:

In order to figure out who climbed the mountain you have to solve using the puthagreom theorem a squared + b squared = c squared

In this case you have multiply 12000 by 2 to replace a squared, you multiply 1500 by 2 to replace b squared and you leave c squared

Once you have that add the two numbers together, 2400+3000, this equals 5400

now you have 5400 = c squared, to solve you have to find the square root of 5400 giving you the rounded number of 73.48=c

After you have completed do the exact same thing with Mountain climber Bob. This gives you the rounded number of 61.64.

therefore, mountain climber Joe has climbed the steepest hill

i think bob climbed the steeper mountain

The age of a cat 2 years or older can be approximately converted into human years by multiplying by 4 and adding 16. Complete the table to represent the relationship between cat age and human years.

Answers

Answer:

Step-by-step explanation:

If the age of a cat is represented by 'x' and human years by 'y', relation between the age of cat and human years will be,

y = 4x + 16 [multiplying cat's age by 4 and by adding 16]

Now from the given table,

If x = 2,

y = 4×2 + 16

  = 24

If y = 3,

y = 4×3 + 16

  = 28

If x = 4,

y = 4×4 + 16

  = 32

If x = 5,

y = 5×4 + 16

  = 36

If x = 6,

y = 6×4 + 16

  = 40

Cat age             2            3           4            5            6

Human years   24          28        32          36          40
