|5k-8| / 10 = 2

|5k-8| / 10 is a fraction btw

Answers

Answer 1

Answer:

The maximum value of k = 5 ³/₅ and the minimum value of k = -2 ²/₅

Step-by-step explanation:

Given;

[tex]\frac{|5k-8|}{10} = 2\\\\|5k-8| = 20[/tex]

Simplifying further;

5k - 8 = 20 ------- (1)

5k - 8 = -20------(2)

Solving equation (1)

5k - 8 = 20

5k = 28

k = 28 /5 = 5 ³/₅

Solving equation (2)

5k - 8 = -20

5k = -20 + 8

5k = -12

k = -12 / 5  = -2 ²/₅

Thus, the maximum value of k = 5 ³/₅ and the minimum value of k = -2 ²/₅

All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set Up Equation

40° + (y + 30)° + y° = 180°

Step 2: Solve for y

Combine like terms:                    2y° + 70° = 180°Isolate y term:                              2y° = 110°Isolate y:                                       y° = 55°
D. 55
Explanation: 3 angles of a triangle must equal 180 so use the formula 180=(angle 1) +(angle 2) +(angle 3)
180=(40)+(y)+(y+30)
Test every answer until you get 180=180
180=40+55+(55+30)
180=40+55+85
180=180
So the answer is 55

How do you graph Y=1.2x-4 ?

Answers

Step-by-step explanation:

Use the y=mx+b reference

the b refers to the y intercept which in your case is -4

so on the graph you would put -4 on the y line so at (0,-4)

Then the m or the slope which is 1.2 means from the point (0,-4) you move 1.2 units up and 1 unit to the right forever to create your line so you continuously move 1.2/1 and -1.2/-1

The required, graph of the linear equation y = 1.2x-4 is shown in the image attached below.

To graph the equation y = 1.2x - 4:

Set up the coordinate plane with the x and y axes.Label the axes as "x" and "y" with numerical markers.Plot the y-intercept: When x = 0, y = 1.2 * 0 - 4 = -4. Plot the point (0, -4).Identify the slope: The coefficient of x is 1.2, which represents the slope.Use the slope to find another point: Starting from (0, -4), move 1 unit to the right (increase x by 1) and 1.2 units upward (increase y by 1.2). Plot the point (1, -2.8).Draw a straight line through the two points you plotted.

The graph of Y = 1.2x - 4 will be a straight line that passes through the points (0, -4) and (1, -2.8), and it will continue infinitely in both directions. The line will slope upwards from left to right with a slope of 1.2.

You and your friend join a new gym that requires a one-time joining fee and monthly payments. Your friend chooses the 1 year plan and pays $687, while you elect the 18 month contract which costs $981. Use this information to determine the linear model used to calculate cost from months of membership.

Answers

Answer:

C = 99 + 49m

x = $99

y = $49

Step-by-step explanation:

Let

x = one time joining fee

y = monthly payment

Your friend:

1 year = 12 months

x + 12y = $687

You:

x + 18y = $981

x + 12y = 687 (1)

x + 18y = 981 (2)

Subtract (1) from (2)

18y - 12y = 981 - 687

6y = 294

Divide both sides by 6

y = 294 /6

= 49

x = $49

Substitute y = 49 into

x + 12y = 687

x + 12(49) = 687

x + 588 = 687

x = 687 - 588

= 99

x = $99

C = 99 + 49m

Where,

C = total charges

m = number of months

99 = a one time joining fee

49 = charges per month

i need help finding the angles

Answers

What way are you trying to solve

Answer:

all angles are 60 degrees

Step-by-step explanation:

since all sides are equal, all angles will be equal so its a equilateral triangle

all angles in a equilateral triangle are 60 as 180/3 is 60

so all angles equal 2x

2x = 60

x = 60/2 = 30
