Answer:

24cm^2

Step-by-step explanation:

w = 2/3l

h = 1/3l

v = lwh

48 = l * 2/3l * 1/31

48 = 2/9l^3

9/2(48) = (2/9l^3)9/2

216 = l^3

cube root of 216 = 6

w = 2/3 * 6 = 4

l = 6

h = 1/3 * 6 = 2

2 * 6 * 4 = 24cm^2

Answer:

Line 1 Slope: - 4/3

Line 2 Slope: 3/4

Line 3 Slope: 3/4

---------------------------------------------------------------------------------------------------------------

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Parallel

Step-by-step explanation:

Line 1: Passes through (6, -4) and (0, 4).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -

(4 - (-4)) / (0 - 6)

(4 + 4) / (-6)

8 / -6

-4 / 3

Slope = - 4/3

___________________________________________________________

Line 2: Passes through (-4, -2) and (8, 7).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -

(7 - (-2)) / (8 - (-4))

(7 + 2) / (12)

9 / 12

3 / 4

Slope = 3/4

___________________________________________________________

Line 3: Passes through (-4, -5) and (4, 1).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -

(1 - (-5)) / (4 - (-4))

(1 + 5) / (4 + 4)

6 / 8

3 / 4

Slope = 3/4

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Parallel

The grid shows the positions, in miles, of a subway stop and a house. The image is of a 2-dimensional graph with an x-axis and a

Arte-miy333 [17]

Here we can use the distance formula. We label one point $( x_{1}, y_{1})$ and the other $( x_{2}, y_{2})$ . It doesn’t matter which point we label with the 1s and which we label with the 2s. The distance will be the same either way (the distance from the subway to the house is the same as that from the house to the subway — to give a related easier to follow example). What does matter is that the 1s are together and the 2s are together.

So let’s call (-4,-3) $( x_{1}, y^{1})$ which means that -4 is $x_{1}$ and -3 is $y_{1}$ . We call the other point (4,3) $( x_{2},y_{2})$

The distance formula is $d= \sqrt{( x_{2} - x_{1} )^{2} +( y_{2}-y_{1})^2 }$

We substitute using the points given and obtain:
$d= \sqrt{(3- - 3) ^{2} +( 4- -4)^2 }$

and simplify to get $\sqrt{16+9}= \sqrt{25}=5$

The distance is 5 miles

Which line contains the point (3,6)? <br><br>Am I correct with answer A? :/

netineya [11]

Replace x with 3 and y with 6 and see which equation is true.

A) y = 7x - 15

6 = 7(3) - 15

6 = 21 - 15

6 = 6

The point (3, 6) makes the first equation true, so the answer is A). Point (3, 6) does not make any other choice a true equation. Answer is definitely A).

Good job!

Does x^2+y^2=9 represent y as a function of x?

aleksley [76]

No, x²+y²= 9 does not represent y as a function of x.

For x= 0,

y²= 9

=>y= ±3,

i.e y has two values +3 and -3

Since single value of x , there are two values of y

For an equation or relation to be function every element in domain( every value of x) there should one distinct value or image in co-domain (one value of y)
