Actually the line would be y=x/2 -3, this is in y=mx+b form. And normally they give you the ordered pairs.

The length of a rectangle is three times the width of the rectangle. The area of the rectangle is 48cm2. Draw the rectangle on t

Schach [20]

Answer:

The width is 4 cm

The length is 12 cm.

Step-by-step explanation:

Area of a rectangle

Given a rectangle of width W and length L, its area is calculated as follows:

$A=W\cdot L$

The area of the given rectangle is 48 cm^2, and the length is three times the width, thus:

L = 3W

Substituting into the formula of the area:

$W\cdot L=48$

$W\cdot 3W=48$

Simplifying:

$3W^2=48$

Solving:

$W^2=48/3=16$

$W=\sqrt{16}=4$

The width is 4 cm. Find the length:

L=3W=3*4= 12

The length is 12 cm.

two blocks of wood are shaped as right rectangle prisms the smaller block has a length of 9 cm a width of 3 cm and a height of 7

dolphi86 [110]

Answer:

1,512 cm³

Step-by-step explanation:

The general formula for the volume of a prism is:

V= Bh, where B = the area of the base and h = height of the prism

Given the dimensions of the smaller block as 9cm x 3cm x 7cm, then the dimensions of the larger block (double the dimensions of the smaller block) must be 18cm x 6cm x 14cm. Using these measurements:

V = (18)(6)(14) = 1,512 cm³

Pls help this is from khan academy

Lena [83]

Answer:

$y=-3x+7$

Step-by-step explanation:

This is asking you to provide the equation is slope-intercept form:

$y=mx+b$

In this equation, m is the slope of the line and b is the y-intercept (where the x value is 0).

By looking at the graph, we can find the y-intercept:

$y-intercept=7\\\\m=7$

To find the slope of the line, you can count how many spaces it takes to go from one point to another. To do this, it's best to find an even point (1,4) and make your way to (0,7).

The slope is represented by $\frac{rise}{run}$ , where the rise is the change in the y-axis and the run is the change in the x-axis.

From (1,4) , move up (rise) as many spaces as it takes to get to the y-axis level of "7", which is 3 spaces. From here, move to the left (run) as many spaces as it takes to get to the x-axis level of "0", which is 1 space. Since you moved to the left, however, this means that the number will be a negative:

$\frac{rise}{run}=\frac{3}{-1}=-\frac{3}{1}=-3$

The slope is -3.

Insert the information into the equation:

$y=-3x+7$

Using words, explain all steps of dimensional analysis when converting 6.7 hectometers to meters.

inessss [21]

6.7 hectometers = 670 meters.

Solution:

Given 6.7 hectometers.

To convert hectometers into meters:

Conversion unit:

1 hectometer = 100 meters

We have 6.7 hectometers.

So multiply 6.7 by 100, we get

6.7 hectometers = 6.7 × 100 meters

= 670 meters

Hence 6.7 hectometers = 670 meters.

In a certain deck of cards, each card has a positive integer written on it. In a multiplication game, a child draws a card and m

jenyasd209 [6]

Answer:

Step-by-step explanation:

since it's multiplication the largest result is the largest integer you have times the second largest integer you have(or itself but not in this case) and the smallest result is the smallest integer you have times the second smallest integer.

so 15 (the smallest result) should be dividable by the smallest integer and 200 (the largest result) should be dividable by the largest integer and if you look at the choices you can see it must be B
