Find the X intercept and the Y intercept for 2x-6y=12

Use Euler's formula for polyhedra: V - E + F = 2  

vertices - edges + faces = 2  

So edges = vertices + faces - 2 = 18 + 11 - 2 = 27.  

Answer:

27 edges.

Answer:

16

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

Direct variation

y = kx

16 = k*8

Divide each side by 8

16/8 = 8k/8

2 = k

The equation is y =2x

y =2x

Let y =32

32 = 2x

Divide by 2

32/2 = x

16 =x

Answer:

3rd one

because they r right angles and congruent to each other and for right angle its is used HS postulate

Answer:

31

Step-by-step explanation:

sum of the bordering angles is 180° so

(5x-16) + (x+10) = 180

5x - 16 + x + 10 = 180

6x - 6 = 180

6x = 186

x = 186 ÷ 6

x = 31

Answer:

The answer is x=31.

5x-16+x+10=180

6x-6=180

6x=186

x=31

Then, 5(31)-16=

155-16= 139

Also, x+10=

31+10=41

Solution check:

139+41=180, so x=31 is correct.

Hello!

[tex]\frac{840}{1152}[/tex]

Divide by 2:

(625) power of 0.16 × (625) power of 0.09 ​

Answer:

[tex]\frac{1}{14}[/tex]

Step-by-step explanation:

[tex]\frac{1}{4} + \frac{23}{28} - 1 = ?[/tex]

First off, let's change everything to a common denominator. This will allow us to add the fractions!

To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.

Let's change the first fraction into a number with a denominator of 28!

[tex]\frac{1}{4} * \frac{7}{7} = \frac{7}{28}[/tex]

[tex]\frac{7}{7}[/tex] = 1. Multiplying a number by one doesn't change its value.

The second fraction, [tex]\frac{23}{28}[/tex], already has a denominator of 28, so we don't have to do anything with it.

Now to the third number, -1:

[tex]-1 = -\frac{1}{1} * \frac{28}{28} = -\frac{28}{28}[/tex]

Now, let's add them all up!

[tex]\frac{7}{28} + \frac{23}{28} - \frac{28}{28} = \frac{7 + 23 - 28}{28} = \frac{2}{28}[/tex]

One last step, to simplify:

[tex]\frac{2}{28} = \frac{1}{14}[/tex]

Answer:

Answer is 221/20

Step-by-step explanation:

if we solve 3 2/5 × 3 1/4

then we will get 221/20.

Part A

The equation is g = -2.5m + 20

The +20 represents us starting with 20 gallons. The -2.5m portion indicates losing 2.5 gallons per minute. So after m minutes, we'll have -2.5m+20 gallons left.

The smallest m can be is m = 0

Let's plug in g = 0 and solve for m to find the largest possible m value

g = -2.5m + 20

-2.5m + 20 = g

-2.5m + 20 = 0

-2.5m = -20

m = (-20)/(-2.5)

m = 8

At the 8 minute mark is when g = 0. So this is when the tub is completely empty. We cannot go beyond this point because g would become negative. So m = 8 is the largest m can get.

This means m is between 0 and 8, including both endpoints.

The domain is [tex]0 \le m \le 8[/tex]

The domain is continuous because the number of minutes is continuous. We cannot have a jump in time from something like m = 1 to m = 2 without values in between. In other words, to go from m = 1 to m = 2, we need to pass by something like m = 1.5

No matter what two values you pick in the interval mentioned, there is always going to be some midpoint and infinitely many other values to deal with.

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

Answers:

======================================================

Part C

See the graph below. The table is included as well.

To generate the table, we select values of m from the domain found earlier. I'm using whole numbers for m, but you can use any real number you want from that interval.

Let's say we picked m = 2

That would mean,

g = -2.5m + 20

g = -2.5*2 + 20

g = -5 + 20

g = 15

So at the 2 minute mark, the tub will have 15 gallons left. That means we'll have a row with m = 2 and g = 15 pair up together. The rest of the table is generated in a similar fashion.

Once the table is set up, you plot all of the points and draw a line through them to complete the graph.

Because we're dealing with a linear function, we only need 2 points at minimum to graph it. However, you can generate as many points as you want. It could be good practice.

Side note: Stuff to the left of m = 0 and stuff to the right of m = 8 is not graphed, as these portions are not in the domain.

Answer:

Step-by-step explanation:

the answer is 16.8

Explanation: well for starters you have to do what's in the parenthesis, so 4 times 1.4 is equal to 5.6. so now we add up the equation and get 28, so now we are left with 28-5.6-5.6 which equals 16.8
