Answer:

slope = \frac{23}{21}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (18, 26)

m = \frac{26-3}{18+3} = \frac{23}{21}

2/3x + 1/4 = 46/6x - 1/3
labwork [276]

Answer:

x = 1/12

Step-by-step explanation:

2/3x + 1/4 = (8x+3) /12   (create equivalent fractions with a denominator of 12)

23/3x - 1/3 = (23x - 1) /3            *(46/6x = 23/3x)

<u>8x + 3</u>  =  <u>23x - 1</u>

    12            3

now cross-multiply:

3(8x + 3) = 12(23x - 1)

24x + 9 = 273x - 12

9 = 252x - 12

21 = 252x

x = 21/252 which reduces to 1/12

Kate is arranging new furniture in her rectangular sitting room. She has mapped the arrangement on a coordinate pane. A,B and C
stepan [7]

Answer:

11 units

Step-by-step explanation:

Given : She has mapped the arrangement on a coordinate pane. A,B and C represent the sofas, V1 and V2 are decorative vases and AQ the aquarium

To Find: The distance between V1 and the aquarium.

Solution:

Referring the given image

We can have the coordinates of V1 and AQ

Coordinates of V1 :(x_{1}, y_{1}) =(-6,5)

Coordinates of AQ :(x_{2}, y_{2}) =(5,5)

Now To find distance use distance formula

d=\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}

d=\sqrt{(5-[-6])^{2} + (5-5)^{2}}

d=\sqrt{11)^{2} + (0)^{2}}

d=\sqrt{11)^{2}}

d=\sqrt{121}

d=11

Hence The distance between V1 and the aquarium is 11 units
