Answer:

-1/2

Step-by-step explanation:

use the slope formula:

(2-4)/(2-(-2)) = -2/4 = -1/2

you can also look at the graph and see it rises -2 (negative means goes DOWN 2) and runs 4, and the slope is rise/run, so it would be -2/4 which simplifies to -1/2

Answer:

The slope is negative one half.

Step-by-step explanation:

Slope is defined as rise over run, or Δx/Δy, when going left to right. In this case, the line goes from (-2,4) to (2,2), so the slope is:

$\frac{2-4}{2 - (-2)} \\\frac{-2}{4}\\= \frac{-1}{2}$

Compute the following volume and surface area.

Vesnalui [34]

The surface area of rectangular solid is 208 square centimeter

The volume of rectangular solid is 192 cubic centimeter

<h3><u>Solution:</u></h3>

Given that rectangular solid has sides of 4 cm, 6 cm, and 8 cm

To find: surface area and volume of rectangular solid

Length = l = 4 cm

Width = w = 6 cm

Height = h = 8 cm

<h3><em><u>The formula to find the surface area of a rectangular prism is:</u></em></h3>

Surface Area = 2wl + 2lh + 2hw

where w is the width, the l is the length, and the h is the height.

$\text {surface area }=2(4 \times 6)+2(4 \times 8)+2(8 \times 6)\\\\\text {surface area } = 2(24) + 2(32) + 2(48)\\\\\text {surface area } = 48 + 64 + 96 = 208$

Thus the surface area of rectangular solid is 208 square centimeter

<h3><em><u>The formula for volume of rectangular solid is:</u></em></h3>

$Volume = Length \times Height \times Width$

$volume = 4 \times 6 \times 8 = 24 \times 8 = 192$

Thus the volume of rectangular solid is 192 cubic centimeter

(4x+2y-6z) + (5y-2z+7x) + (-9z-2x-3y)

Free_Kalibri [48]

Answer:

9x+4y-17z

Step-by-step explanation:

first open brackets with d signs

dat is= 4x+2y-6z+5y-2z+7x-9z-2x-3y

collect like terms and = 4x+7x-2x+2y+5y-3y-6z-2z-9z= 9x+4y-17z

Write a proportion to find how many points xx a student needs to score on a test worth 50 points to get a test score of 78%.

Archy [21]

Let
x = points that a student needs to score on a test
p = points worth the exam.
to find how many points to student needs to score on a test to get a test score of 78%. it will be given by
x = 0.78 * p
Thus, in a 50-point test, the number of points the student needs to get to get a test score of 78% will be
x = 0.78 * 50 = 39 points.

What is the equation of a parabola with a vertex at (0,0) and a focus at (0. -5)

Vesna [10]

The focus it the point, so all you have to do is plot the focus on a graph. Then, draw a line to the point of origin and calculate the equation. This equation in slope intercept form would be y=-x+0
