I basically solved for x first.
42+43x+1=180
X=3.2 rounded

Next plug in the value of x into the EDC equation
43(3.2)+1=138.6

Then add it to the measure of EDN
138.6+42= 180.6

So the answer is measure of NDC= 138.6

Answers

Answer:

Ok you're talking about "PI"

Area of a circle:

πr^2

What that basically means is

π <- That sign is 3.14

You wanna times that with the radius (r).

The radius is half of the diamater so divde the diameter by 2 then mutiply whatever u get with 3.14

Then the final step is do 3.14 x radias then times 2.

That's it :D

The midpoint of AD is C. The midpoint of AC is B. If A is at (-10,4) and D is at (2,12), find the coordinates of B. Group of answer choices (-5,5) (-4,8) (-2.5,9) (7,6)

Answers

Answer:

[tex]B(x,y) =(-7,6)[/tex]

Step-by-step explanation:

Given

[tex]A = (-10,4)[/tex]

[tex]D = (2,12)[/tex]

Required

Determine the coordinates of B

C is the midpoint of AD. So, we calculate the coordinates of C, first.

[tex]C(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where:

[tex]A = (-10,4)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]D = (2,12)[/tex] --- [tex](x_2,y_2)[/tex]

So, we have:

[tex]C(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

[tex]C(x,y) = (\frac{-10+2}{2},\frac{4+12}{2})[/tex]

[tex]C(x,y) = (\frac{-8}{2},\frac{16}{2})[/tex]

[tex]C(x,y) = (-4,8)[/tex]

So, the coordinates of C is (-4,8)

The midpoint of AC is B.

So, we calculate the coordinates of B using:

[tex]B(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where:

[tex]A = (-10,4)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]C(x,y) = (-4,8)[/tex] --- [tex](x_2,y_2)[/tex]

So, we have:

[tex]B(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

[tex]B(x,y) =(\frac{-10-4}{2},\frac{4+8}{2})[/tex]

[tex]B(x,y) =(\frac{-14}{2},\frac{12}{2})[/tex]

[tex]B(x,y) =(-7,6)[/tex]

Hence, the coordinates of B is (-7,6)

None of the options is correct.

Answers

Answer:

x = 0 and y = -2

Step-by-step explanation:

x - 2y = 4 and X - 1y = 2

you mentioned elemination aka substraction

so you when substract x - x = 0 -2y -( -y) = -y and 4 -2 = 2

so - y = 2

or y = 2

now substitute the numbers

x + 4 = 4

x = 0

What is the mean of the values in the dot plot?

Enter your answer in the box.

Answers

Answer:

The mean is 46.

Step-by-step explanation:

To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.

40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50

Multiply what's in the parentheses.

40 + 82 + 45 + 96 + 147 + 50

Add, going from left to right

122 + 45 + 96 + 147 + 50

167 + 96 + 147 + 50

263 + 147 + 50

410 + 50

460

Now, divide that by how many dots there were (10).

460/10

The mean of the values in this dot plot is 46.

Work out

x

Answers

Answer:2

Step-by-step explanation:

For line y = 9x, m = 9 and c = 0

What is the slope-intercept form of the line?

"y = mx + c, where m is the slope of the line and c is the y-intercept of the line."

What is slope of the line?

"It is the change in y coordinate with respect to the change in x coordinate."

What is y-intercept?

"It is a point at which a line intersects the Y-axis."

For given question,

We have been given an equation of line y = 9x

By comparing above equation of line with the slope-intercept form of line,

m = 9 and c = 0

This means the slope of the line y = 9x is 9 and the y-intercept is 0

Therefore, for line y = 9x, m = 9 and c = 0
