PLEASE HELP ME ITS WORTH 25 pts (question number 29)
Dmitry [639]

Answer:

A, C, D

Step-by-step explanation:

In a proportional relationship, y = kx, k is the constant of proportionality.

A)

4y = x

y = 1/4 x

k = 1/4      Yes

B)

y = 4x

k = 4      No

C)

32y = 8x

y = 8/32 x

y = 1/4 x

k = 1/4    Yes

D)

y = 0.25x

k = 0.25 = 1/4     Yes

E)

1/4 y = 2x

y = 4 * 2x

y = 8x

k = 8     No

(-3,y), (-9,-2); m=1
12345 [234]

Answer:

The value of y is 4

The equation of line is y = x + 7   .

Step-by-step explanation:

Given as :

The points are

(x_1, y_1) = (- 3, y)

(x_2, y_2) = (- 9, -2)

The slope = m = 1

Now,<u> The slope is calculated in points form</u>

So, Slope = \dfrac{y_2-y_1}{x_2-x_1}

I.e m = \dfrac{y_2-y_1}{x_2-x_1}

or, 1 = \dfrac{- 2 - y}{- 9- (-3)}

or, 1 = \dfrac{- 2 - y}{- 6}

or, 1 × (-6) = - 2 - y

or, - 6 = - 2- y

or, y = - 2 + 6

∴ y = 4

So, The new points as

(x_1, y_1) = (- 3, 4 )

(x_2, y_2) = (- 9, -2)

<u>So, the equation of line in slope - point form can be written as</u>

y - y_1 = m ( x - x_1 )

i.e y - 4 = ( 1 ) × ( x - (-3) )

or, y - 4 = x + 3

∴ y = x + 3 + 4

Or, y = x + 7

So, The equation of line is y = x + 7

Hence The value of y is 4

And The equation of line is y = x + 7   . Answer

Someone please help me with number 4
AVprozaik [17]
The answer is 10√3 because
10√3 is equal to approximately 17.32051 and the formula for finding the area of a square is length multipled by width so 10√3 x 10√3 is equal to 300 or 17.32051 x 17.32051 is equal to 300
