y= 9² = 81

Answer:

D) 121 degrees

Step-by-step explanation:

A linear pair is a pair of angles that share a side and a base. In other words, they are the two angles created along one line when two lines intersect. Linear pairs are always supplementary.

In this case, since supplementary angles add up to 180 degrees, we set up an equation:

<A+<B=180

(6x-19)+(11x-22)=180

17x-41=180

17x=221

x=13

Now we plug in x=13 for angle B:

11x-22

11(13)-22

143-22

121

Therefore, the measure of angle B is 121 degrees

Answer:

-1 + 6i

Step-by-step explanation:

Subtract/add the imaginary parts and then add real parts.

Open the parenthesis by multiplying the each term of 4 - 2i by (-1)

3 + 4i - (4 - 2i) = 3 + 4i - 4 + 2i

                       = 3 - 4 + 4i + 2i

                       = -1 + 6i

Answer:

slope is m= 5/7

Step-by-step explanation:

m= y2-y1/x2-x1

m= 3-(-2)/ 9-2

m= 5/7

Slope = change in Y over change in X

Slope = (3- -2) / (9 - 2)

Slope = 5/7

Answer:

(x + 7) (x + 7)

Step-by-step explanation:

What's the square root of x^2?

That's x

What's the square root of 49

That's 7

And what makes 14?

7 + 7 = 14

So therefore the answer is (x + 7) (x + 7)

Easy Kevin Durant is so smart!

Answer:

The middle number is 14 and the last number is 49.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 14

Multiply together to get 49

Can you think of the two numbers?

Try 7 and 7:

7+7 = 14

7*7 = 49

Fill in the blanks in

(x+_)(x+_)

with 7 and 7 to get...

(x+7)(x+7)

Answer:

(x+7)(x+7)

3 out of 12

Answer:

The image of P(11,-4) will be: P'(-6, -2)

Step-by-step explanation:

Given the point

The rule:

(x, y) = (x– 17, y+2)

Meaning the image of P(11,-4) can be determined by subtracting 17 units (moving left) from the x-values and adding 2 units (moving up) to the y-values.

Therefore,

P(11, -4) → P'(11-17, -4+2) = P'(-6, -2)

Thus, the image of P(11,-4) will be: P'(-6, -2)

Answer:

9/7

Step-by-step explanation:

-24/35 ÷ -8/15

=-24/35 × -15/8

=9/7

Answer:

9/7

Step-by-step explanation:

when dividing with a fraction, the -8/15 reciprocates to 15/-8. Then, -8 cancels out -24 remaining with 3 since they are both negative while 15 and 35 have a common of 5 giving them a remainder of 3 and 7 respectively. you then multiply what you have which is 3/7 * 3/1 giving you 9/7.

Answer: Choice A)

[tex]H = \frac{SA}{2(L+W)} - \frac{LW}{L+W}\\\\[/tex]

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

Work Shown:

[tex]SA = 2(LW + LH + HW)\\\\2(LW + LH + HW) = SA\\\\LW + LH + HW = \frac{SA}{2}\\\\LH + HW = \frac{SA}{2} - LW\\\\H(L + W) = \frac{SA}{2} - LW\\\\H = \frac{\frac{SA}{2} - LW}{(L + W)}\\\\H = \frac{SA}{2(L+W)} - \frac{LW}{L+W}\\\\[/tex]

This is not the only way to solve for H.

Answer:

Should have taken the absolute value

Actual length = 3.5 centimeters

Step-by-step explanation:

Length is always a positive value or zero

So one should take the absolute value which is always positive

|-3.5| = 3.5 where the | | denotes absolute value of what is enclosed

Answer:

The correct answer is City D.

Step-by-step explanation:

When you say the phrase, "closer to sea level" you mean the closest to the very top of the sea, like "0" on a number line.

This means, that whether it is to the left of the right of the number line (or above or below the sea) whichever one has the lowest absolute value is the closest.

Therefore, the correct answer is City D.

Hope this helps! :D

Answer:

[tex]\frac{7}{16}[/tex] in., [tex]\frac{5}{8}[/tex] in., [tex]\frac{3}{4}[/tex] in., 1[tex]\frac{5}{16}[/tex] in., 1[tex]\frac{3}{2}[/tex] in.

Step-by-step explanation:

Diameters of the belt produced are given in fractions which can be converted to decimals to know their values.

Thus,

1 3/2 in. = [tex]\frac{5}{2}[/tex] in. = 2.5 in.

7/16 in. = 0.4375 in.

3/4 in. = 0.75 in.

5/8 in. = 0.625 in.

1 5/16 in. = [tex]\frac{21}{16}[/tex] in. = 1.3125 in.

Arranging the vales from least to greatest, we have;

0.4375 in., 0.625 in.,0.75 in., 1.3125 in., 2.5 in.  = [tex]\frac{7}{16}[/tex] in., [tex]\frac{5}{8}[/tex] in., [tex]\frac{3}{4}[/tex] in., 1[tex]\frac{5}{16}[/tex] in., 1[tex]\frac{3}{2}[/tex] in.

The option b and c is correct.

To solve this problem we must be aware of the concepts of line segment. And also what is a mid point.

When we connect two dots or two points it forms a line segment or we can say that line segment is part of line which is bounded by two points.

Mid-point of any line or line segment is that point which divides the line segment into two equal parts and also a point which is equidistant from the two endpoints.

So, a midpoint of a line segment divides the line segment in two equal parts and is also equidistant from the two endpoints.

Here, the appropriate option is b and c.
