Answer:

106

Step-by-step explanation:

If you find the sum of the interior angles, you can determine the supplement to z.

Then all you have to do to get z is to subtract it from 180.

Method

The supplement of 72 is 180 - 72 = 108

The supplement of 51 is 180 - 51 = 129

The supplement of 60 is 180 - 60 = 120

The supplement of 71 is 180 - 71 = 109

Let y = the supplement of z

y + 108 + 129 + 120 + 109 = 540

y + 466 = 540

y = 540 - 466

y = 74

z + y = 180

z + 74 = 180

z = 180 - 74

z = 106

I hope that get's rid of your headache.

BigorU [14]

Answer:

18,480

Step-by-step explanation:

you would fine how much she put in the bank in the first place!

250,000-96,000=154,000

Then you would do 154,000*0.02 to find how much interest is charged per month.

154,000*0.02=3080

Finally, you would multiply 3080 by 6 {because you need to account for all of the months}.

3080*6=18,480

What is the y-intercept of the function f(x) = -2/9x+1/3?

Brilliant_brown [7]

Answer:

y- intercept = $\frac{1}{3}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

f(x) = - $\frac{2}{9}$ x + $\frac{1}{3}$ ← is in slope- intercept form

with y- intercept c = $\frac{1}{3}$

Step-by-step explanation:

$\text{If an urn contains two blue balls} (denoted \:B_1 \:and \:B_2) \text{and three white balls}$ , $(denoted \:W_1, W_2, \:and\: W_3)$

If One ball is drawn, its color is recorded, and it is replaced in the urn. Then another ball is drawn and its color is recorded.

Find the slope of the line that goes through the given points.<br> (3,4) and (-9,4)

iogann1982 [59]

9514 1404 393

Answer:

Step-by-step explanation:

The slope can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (4 -4)/(-9-3) = 0/-12 = 0

The slope of the line is zero. It is a horizontal line (y=4).
