Answer:

9

Step-by-step explanation:

The exterior angle is equal to the sum of the 2 opposite interior angles, therefore:

9x + 9 = 45 × 5x

4x = 36

x = 9

Answer:

  1. x = {6, 16}

  2. (x -8)² +(y +7/3)² = 64

Step-by-step explanation:

1. The distance formula is useful for this.

  d² = (x2 -x1)² +(y2 -y1)²

  13² = (x -11)² +(-5 -7)² . . . . . . . . fill in the given point coordinates

  169 -144 = (x -11)² = 25 . . . . . . subtract 144

  x -11 = ±5 . . . . . . . . . . . . . . . . . take the square root

  x = 11 ±5 = {6, 16} . . . . . . . . . . add 11

The values of x that make the points 13 units apart are 6, 16.

2. The standard form equation of a circle is ...

  (x -h)² +(y -k)² = r² . . . . . . circle centered at (h, k) with radius r

In order for the circle to be tangent to the y-axis, the radius must be equal to the distance the center is from the y-axis: the x-coordinate of the center point. That is, r = 8.

  (x -8)² +(y +7/3)² = 64

Answer:

The second line.

Step-by-step explanation:

The line starts off at 0 and goes up to 0.8.

As you can see it goes up .3 more.

.8 + .3 = 1.1

just as 8 + 3 = 11 but with decimals.

Answer:

16

Step-by-step explanation:

it doubles every time    2,4,8. 16

Answer:

12= ax - x + b

Step-by-step explanation:

5x -4(x - 3) - 8 = ax + b

5x -4x + 12 - 8 = ax + b

x + 12 = ax + b

12= ax - x + b

Answer:

Mean = 9

Step-by-step explanation:

The mean is the average of a data set.  Given the values, 2, 9, 10, 12, 12:

Add all the numbers in the data set, and divide its sum by the number of items in the set:

Mean = [tex]\frac{2+9+10+12+12}{5}[/tex] =  [tex]\frac{45}{5}[/tex] = 9

Therefore, the mean of the given data set is 9.

Answer:

23/133

Step-by-step explanation:

If your total is 133, that would become your denominator, your numerator is how many students of those are freshman in which this case is 23.

The total number of freshmen in the school is 23/133

The number of students in the small school is 133

23 out of the 133 students are freshmen

Therefore the fraction of freshmen in the school can be calculated by dividing 23 by 133

Fraction of freshmen is 23/133

Answer:

4[tex]\sqrt{2}[/tex] cm AND 2[tex]\sqrt{2}[/tex] cm

Step-by-step explanation:

The length of a diagonal of a square means finding the hypotenuse (long side) of a right triangle with legs of the length of the side of the square. This means you can use a^2 + b^2 = c^2 to solve for the diagonal. Plugging in your values gets you 4^2 + 4^2 = c^2, simplify to get 16 + 16 = c^2, simplify further to get 32 = c^2. Isolate c by taking the square root of both sides to get [tex]\sqrt{32}[/tex] = c, which you can simplify by listing out the factors of 32 and finding pairs. 32 = 2 * 2 * 2 * 2 *2 (5 of them), meaning its square root is 4[tex]\sqrt{2}[/tex], which is the length of the diagonal. Don't forget your units! (:

For the second part, remember that the distance between the corner to the center of a square is half the diagonal of the square. You already have the length of that diagonal, so all you have to do is divide it by 2. Do so and you get 2[tex]\sqrt{2}[/tex]. Once again, don't forget your units! (:

If you're required to give decimal estimates, then pop those final answers into a calculator and round to the specified number of decimal places. No one will ask you to calculate irrational square roots, or at least no one should.

Answer:

A

Step-by-step explanation:

Given a function f(x) where the first derivative with respect to x evaluated in two equals

f'(2)=1/2

The slope of the tangent line is

mt=1/2

Therefore, the slope of the normal line is

mn=-1/(1/2)

mn=-2

Evaluating the given point in the general form

y-y1=m(x-x1)

y-(-1)=-2(x-2)

y+1=-2x+4

y=-2x+3

Answer:

g=4.56

Step-by-step explanation:

g+3.42=7.98

Subtract 3.42 from each side

g+3.42-3.42=7.98-3.42

g=4.56

Answer:

4.56

Step-by-step explanation:

Answer:

[tex]x + y = 24[/tex]

[tex]x - y = 4[/tex]

Now, add these two equations.

You get,

[tex]2x = 28[/tex]

[tex]x = \frac{28}{2} [/tex]

[tex]x = 14[/tex]

Given,

[tex]x + y = 24[/tex]

[tex]14 + y = 24[/tex]

[tex]y = 24 - 14[/tex]

[tex]y = 10[/tex]

You can test this to the other equation as well.

[tex]x - y = 4[/tex]

[tex]14 - 10 = 4[/tex]

Hence, the two numbers are 14 and 10.

Answer:

13/6

Step-by-step explanation:

Answer: 1/6

Step-by-step explanation:

There is a slope formula for this.

(x1,y1)= (-4,6)

(x2,y2)= (2,7)

Plug it into the formula:

[tex]\frac{7-6}{2-(-4)}= \frac{1}{6}[/tex]

The slope is 1/6. It doesn't matter which set of coordinates you use for x1, y1.

Answer:

It is a vertical line at x = 0

Step-by-step explanation:

An equation of a line in a slope-intercept form is y=mx+b

So with the coordinates given, we must find the slope (m), and the y-intercept (b).

In order to find the slope using these coordinates,

we have to use the formula (y2-y1)/(x2-x2).

So the slope would be -3 - 4 / 0.

Because the denominator is 0, the slope would be undefined.

It is easier to see the equation/graph by graphing the coordinates on the coordinate plane. You will see that it is a straight vertical line down x=0.

Hello there! :)

We can use the formula:

[tex]\frac{y2-y1}{x2-x1} \\[/tex]

First, let's take a look at the x-coordinates. They are the same, aren't they?

If the x-coordinates are the same, then the slope is undefined.

Put the x-coordinates into the formula. It turns out that we divide by 0, and division by 0 is undefined.

Hope this helps!
