The Picture Shows The Graphs Of The Functions Expressed By A Formula Of The Following Type: Y = Kx +

Answers

Answer 1

Answer:

line 1: y= 1x+ 2

line 2: y= -1x-0.5

(usually 1 is omitted but I added for clarity)

Step-by-step explanation:

slope (x)= yfinal-yintial/xfinal-xinitial

b= where line intersects y axis

line 1:  (-1,0), (0.5,1.5)

(1.5-0)/(0.5-(-1))

(1.5)/(1.5)

slope= 1x

y=x+ 2

line 2: (-0.5,0), (0.5,-1)

(-1-0)/(0.5-(-0.5))

(-1)/(1)

slope= -1x

y=-x-0.5

Answer 2
first: k is 1, b is 1.
second: k is -1, b is -0.5

Ruby bought 15 cell phone cases for a total of $145.80. She sells them for $19.50 each, but she is only able to sell 5 of them. What is Ruby’s net profit or loss. Show work.

Answers

Answer:

$48.30

Step-by-step explanation:

Total profit after selling 5 cases:

[tex]5 \times 19.50 = 97.50[/tex]

Net loss:

[tex]145.80 - 97.50 = 48.30[/tex]

Answer:

She profited $9.78 for each of the 5 cases but she loss $48.3 in total.

Step-by-step explanation:

The principal amount for each case is 9.72. (So 19.5 - 9.72 = 9.78. )

For the loss, the money she used to buy - the amount she sold = loss.

( 145.8 - 97.5 = $48.3)

Square roots and the phythagoran theorem

Answers

Answer:

square root of 15= 225+ Square root of 9+ 81

225+81=17.49

Step-by-step explanation:

Answer: b = 12

Step-by-step explanation: a² +b² = c²

a² + 9² = 15²

a² + 81 = 225

a² = 225 - 81

a² = 144

√a² = √144

a = 12

Answer:

[tex]k=10[/tex]

Step-by-step explanation:

Given the following question:

[tex]4+k=14[/tex]

In order to answer one-step equations, we have to isolate the variable to do this we need to use inverse of operations.

[tex]4+k=14[/tex]
[tex]4-4=0[/tex]
[tex]14-4=10[/tex]
[tex]k=10[/tex]

To prove your answer:
[tex]10+4=14[/tex]
[tex]=4[/tex]

Your answer is "k = 10."

300 = 1/3 x B x 9

10 x 1/3 = 10,3

300/10,3 = 90

B = 90^2

Answer: 22ft^3

Step-by-step explanation:

First, find the volume of the little cubes that the rectangular prism can hold inside of itself.

The formula for volume of a rectangular prism is:

V = length x width x height.

= 1/2 x 1/2 x 1/2

= 1/8

Now, since the rectangular prism can hold 176 of these cubes, you need to multiply each cubes volume, 1/8, by 176. 1/8 x 176 = 22

Therefore, the volume of the box is 22ft^3
