Answer:

∠ 1 and ∠2

Step-by-step explanation:

Adjacent angles share a common ray or side between them, and have the same vertex.  

Therefore, the adjacent angles from the given image are: ∠ 1 and ∠2.

The other given options are not adjacent angles because they do not have the same common vertex and ray.  

The given question requires the expansion of the expressions within the bracket to the stated power. This would give an answer that is equal to -64.

This expansion requires the substitution of the given values, a and b, into the expression in the bracket. Then expanding the determined answer to the stated power.

Here, subtract the value of b from that of a, then expand the answer to the power of 3.

Thus:

[tex](a - b)^{3}[/tex]

Given that; a = 3, and b = 7, then we have:

[tex](a - b)^{3}[/tex] = [tex](3 - 7)^{3}[/tex]

           = [tex](-4)^{3}[/tex]

           = -4 * -4 * -4

           = -64

Therefore with the given conditions in the question, we have:

       [tex](3 - 7)^{3}[/tex]  = -64

Answer:  y-intercept is -6

Step-by-step explanation:  Calculate the slope of the line between the two given points:

Rise/Run = slope, m in the standard form of  a straight line:  y=mx+b, with b the y-intercept (the value of y when x=0).

Rise = 1 - (-6) = 7

Run = 4 - (-3) = 7

Slope = Rise/Run, 7/7, or 1

y=mx+b

y = 1x+ b

Find b by entering one of the two given points.  I'll pick (4,1).

y = 1x+ b

What's important now is the next step.  The equation "that is parallel" must have the same slope as the reference equation, 1 in this case.

[If, out of curiosity, you want the full equation of the reference line, we can find b in this way:

Enter one of the two given points and solve for b.  I'll pick (4,1):

y = 1x+ b

1 = 1*(4)+ b

b = -3

y = 1x - 3 is the first equation.]

All we really needed from the first, or reference, equation is the slope, 1 in this case.  Parallel lines have the same slope, so we want an equation in the form:

y=1x+b

This equation will be parallel, regardless of the value of b.  But we want it to go through a specific point, (7,1).  So use that point and solve for b:

y=1x+b

1=1*7+b

b=-6

The equation is y=1x-6

Answer:

x = 10

Step-by-step explanation:

Given h(x) = 2x - 14 and h(x) = 6, then equating

2x - 14 = 6 ( add 14 to both sides )

2x = 20 ( divide both sides by 2 )

x = 10

Answer:

[tex]18 {m}^{2} [/tex]

Step-by-step explanation:

[tex]area \: = 6m \times 4m \\ = 24 {m}^{2} \\ \\ grass \: area = 3m \times 2m \\ = 6 {m}^{2} \\ \\ cement \: area \: = 24 {m}^{2} - 6 {m}^{2} \\ = 18 {m}^{2} [/tex]

Answer:

18 m^2

Step by step explanation:

In these types of math problems, we have two ways to solve.

1) Directly find the area of the shaded area.

2)Find the unshaded area and then minus that from the total area.

In this case, I will use the second way.

The grass area (unshaded) is 3 x 2 = 6 m^2 ( 6 square meters )

The total area (grass + cement) is 4 x 6 = 24 m^2 ( 24 square meters )

Now, we want the area of the cement part but the grass's area is also in the total.

So, we minus 6m^2 from 24m^2.

Then we get 18m^2.

And that is the answer.

I hope it helps.

(Note : because this problem is easy, you can use both ways but most use the second way. There may also be problems where we can use only the first or second way.)

Answer:

[tex](0;-4) (3,0); (6,4); (9,8)[/tex]

Step-by-step explanation:

You will end up with ordered pairs. the way to find them is to assign convenient values to either x OR y, and find the remaining ones. by "convenient" i would recommend having either equal to zero, and then playing with coefficients so that something else goes to "convenient" numbers - since I'm lazy and I hate typing fractions in here.

[tex]x= 0 \rightarrow 4(0) -3y=12 \rightarrow y=-4;\\y=0 \rightarrow 4x -3(0) = 12 \rightarrow x=3;\\x=6 \rightarrow 4(6)-3y=12 \rightarrow -3y=-12 \rightarrow y=4\\y= 8 \rightarrow 4x-(3)(8)=12\rightarrow 4x=36 \rightarrow x=9[/tex]

How did I choose 6 and 8? Mostly practice and a bit of good eye. 12 at the RHS is 4 times 3, and the LHS is 4 times something, minus 3 times something else, so it was a good bet that picking multiples of the other something would cancel out.

Step-by-step explanation:

by Pythagorean theorem

The correct statement to find the measure of EC is: Create a proportion with the legs of the triangles where segment BC is the same measure as segment AB. Add the length of segments BC and BE to find the length of segment EC.

Since BE is parallel to AD, triangles ADC and BEC are similar by the Alternate Interior Angles Theorem. Therefore, the ratio of corresponding sides of these triangles is equal:

AD / BC = DC / EC

Since AD = 4√138 m and BC = AB = 6√3 m, we have:

4√138 / 6√3 = DC / EC

Simplifying:

2√3 / 3 = DC / EC

Now, we know DC = BE = √138 m. Let's substitute that value:

2√3 / 3 = √138 / EC

Now, solve for EC:

EC = (√138 * 3) / (2√3)

EC = 3/2 * √(138/3)

EC = 3/2 * √46

Thus, the measure of EC is 3/2 * √46 m. The correct statement provided earlier explains the process to find this value.

Step-by-step explanation:

a value is less than 1 but greater than 0, making it decay.

All of those claims are true.

We can describe positive temperatures such as room temperature (20 degrees C = 68 degrees F), and we can have negative temperatures as well (eg: -40 degrees C = -40 degrees F). The only time we cannot have negative temperature is when you use the Kelvin temperature scale. This is because absolute 0 represents the coldest possible temperature in the universe. In more common settings, Celsius and Fahrenheit are frequently used.

Debt and money are often involving negative integers. If we were to write -7 in terms of money, then it could represent a person owing $7. Positive values represent having the actual money and not being in debt.

When it comes to elevations, positive integers represent being above sea level; while negative values are below sea level. For example, Mount Everest is +29035 above sea level (or simply 29035 ft) and the Mariana Trench roughly has an elevation of -36201 ft (meaning it's about 36201 ft below sea level).

Answer:

35 5/27

Step-by-step explanation:

You just have to set up an equation:

0.9/95 = 1/x

And if you cross-multiply, you get:

0.9x=95

Which means x is 95/0.9 which is 105 5/9. So, if all three t-shirts costed 105 5/9, and they all costed the same, then one t-shirt costs 35 5/27.
