Describe what happens to the graph of y=3x+4 when the slope is changed to 1/3

1 answer:

Maurinko [17]3 years ago

3 0

The graph is still a straight line, it still cuts the y-axis at the point y=4 ,
and it still slants up from left to right.

But it becomes a lot less steep. The original line only had to go <em>4 inches</em>
to the right in order to rise 1 foot. The new line has to go <em>3-feet</em> to the right
in order to rise 1 foot.

A line contains the points (82,−96) and (87,−86) .

levacccp [35]

A line contains the points (82,−96) and (87,−86)

To find slope of a line we use formula

We are given with two points (x1,y1) and (x2,y2)

x1= 82, y1=-96, x2=87, y2=-86

plug in all the values in the formula

$slope =\frac{ (y_2-y_1)}{x_2 - x_1}$

$slope =\frac{ (-86-(-96))}{87-82}$

$slope =\frac{ (10)}{5}=2$

Slope of the line = 2

Two rectangular prisms have the same volume. The area of the base, B, of the blue prism is 418 square units. The area of the bas

kenny6666 [7]

Answer:

The height of the blue prism is half the height of the red prism

Step-by-step explanation:

Represent the volume of the blue prism with Vb and the red prism with Vr

So, we have:

$V_r = V_b$

$A_b = 418$ --- base area of the blue

$A_r = \frac{1}{2}A_b$ --- base area of the red

Required

Determine which statement about the heights of the prisms is true

Volume is calculated as:

$Volume = Base\ Area * Height$

For the blue prism:

$V_b = A_b * h_b$

For the red prism

$V_r = A_r * h_r$

Equate both volumes

$V_r = V_b$

$A_r * h_r = A_b * h_b$

Substitute the expression for $A_r$

$\frac{1}{2}A_b * h_r = A_b * h_b$

Divide both sides by $A_b$

$\frac{1}{2} h_r = h_b$

<em>This implies that the height of the blue prism is half the height of the red prism</em>
