Answer:

1.5

Step-by-step explanation:

The front elevation of the cube will be either a square or a rectangle.

A three-dimensional object with six congruent square faces is called a cube. The cube's six square faces all have the same dimensions.

Given that, a solid shape is made from 4 cubes.

The front face of a cube is square, therefore, the front elevation of 4 cubes will be either a square or a rectangle.

Hence, the front elevation of the cube will be either a square or a rectangle.

Answer:

Slope would be m= -1, y-int is 2.

Step-by-step explanation:

To find slope, use (y2-y1/x2-x1) Plugging this in, we get (-5-(-1)/(7-3). This can be simplified to -4/4, which is -1. After we find slope, we plug in one of the points to find be. Using (7,-5), y=-5 and x=7. So, -5=7(-1)+b. -5=-7+b. Add 7 to both sides, b=2. Therefore, the entire equation is y=-x+2.

Answer:

The answer is 1

Step-by-step explanation:

use slope formula!

[tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex]

3 is xsub1

-1 is ysub1

7 is xsub2

-5 is ysub2

substitute and solve!

[tex]m= \frac{-5-(-1)}{7-3}\\= \frac{-5+1}{4}\\= \frac{-4}{4}\\= -1[/tex]

slope is 1

Answer:

Look down below

Step-by-step explanation:

It's been a little while since I've looked at compound inequalities, so forgive me if this is a bit long.

Let's start with the Low Elevation Forest. Let x represent what is considered the forest. If this is above 1700, x>1700 (which can be rewritten as 1700<x). (Remember, as silly as this may sound, the mouth of the alligator eats the larger part! So the large number has the wide part of the symbol. Remember also that if the sign is < or >, then it includes the number the 'mouth' is facing.) If the forest is up to 2500, you'll generally include 2500 in your equation, so x<2500. This means 1700<x<2500 or x>1700 and x<2500.

Now let's repeat that with the other parts of the question. Mid elevation is x>2500 and x<4000. Subalpine would be x>4000 and x<6500. Alpine is then x>6500 and x< the summit (which is probably the elevation of Mount Rainer in this problem or 14410 feet).

Now we have the question itself. Let's replace x with t for trees for part a. This would mean in the low elevation forest, t>1700 and t<2500 which can be rewritten 1700<t<2500. Now we have flowers in the subalpine AND alpine zones. Let's use f for flowers. If flowers can be in either zone, let's combine them! Because t>4000 and t<6500 in the subalpine level and t>6500 and < the summit (aka 14410 feet), flowers can grow anywhere  above 4000 feet. So flowers would be f>4000 and f<14410. Again, you can combine these into: 400<f<14410.

Sorry this is so long, but I hope it helps :)

Answer:

10 + m  ≥ 30

You must spend AT MOST $20 or more

Step-by-step explanation:

Basically you have already spent 10 dollars and you have to pay MORE than or equal to 30. You cannot pay less than because you want the free songs. So the sign has to be  ≥ or the inequality will not be true.

10 + m  ≥ 30

10 - 10 + m  ≥ 30 - 10     ( subtract 10 from each side to isolate m)

m  ≥ 20     ( we are left with this )

The answer is :

m  ≥ 20

You must spend at most 20 dollars more to get the 3 free cd's. Your welcome :D

Answer:

No, it is not. A reasonable product is 31,770.

Step-by-step explanation:

Ever heard of a calculator? It's way faster.

45 x 100 = 4,500

4,500 x 7 = 31,500

45 x 6 = 270

31,500 + 270 = 31,770

Answer:

y = -½x + 3

Step-by-step explanation:

The equation of a line in slope-intercept form is

y = mx + c

where m is the gradient (slope) and c is the y-intercept

We can find the gradient and intercept from the two points on the diagram

The points are:

(0, 3) and (4, 1)

The y-intercept is when x = 0

we are already given this point so

c = 3

now we can use our other point to find m. So:

1 = 4m + 3

-2 = 4m

-½ = m

Now we can put both variables into our slope-intercept form

y = -½x + 3

Answer:

[tex]\frac{c + d}{2}= \frac{c + d}{2}[/tex]

Step-by-step explanation:

Required

Write the given statement as an equation

To start with, we solve for the average of c and d

[tex]Average = \frac{\sum x}{n}[/tex]

[tex]Average = \frac{c + d}{2}[/tex]

Next, is to determine half sum

[tex]Half\ sum = \frac{c + d}{2}[/tex]

Since both are equal; we have"

[tex]\frac{c + d}{2}= \frac{c + d}{2}[/tex]

The above shows that the statement is true

Answer:

100 pounds

Step-by-step explanation:

2/5 ton equals 800 pounds

800 divided by 8 equals 100 pounds

Given function:

       f(x) = 2 - 5x

Table;

        x                        f(x)

        -2                         12

         -1                          7

         0                          2

          1                          -3

          2                        -8

The function is f(x) = 2 -5x

For;   x = -2;        f(x) = 2 - 5(-2)  = 12

                            f(x) = 2 - 5(-1) = 7

                            f(x) = 2 - 5(0) = 2

                            f(x) = 2 - 5(1) = -3

                            f(x) = 2 - 5(2) = -8

Answer:f(x) = 2 - 5(-2)  = 12

                           f(x) = 2 - 5(-1) = 7

                           f(x) = 2 - 5(0) = 2

                           f(x) = 2 - 5(1) = -3

                           f(x) = 2 - 5(2) = -8

The function f ( x ) = 2 − 5 x.

Plug in-  f ( 2 ) = 2 − 5x2

Simplify
