Answer:

D.

Step-by-step explanation:

7 5/6 - 9 3/4 = −1 11/12

(-7 5/6) + (-9 3/4) = −17 7/12

(-7 5/6) * 9 3/4 = -76 3/8

(-7 5/6) / (-9 3/4) = 94/117

This is easy to figure out at a glance, but I thought whole answers would be easier to understand.

So basically, the equations two negatives are better off being crossed off if negatives are being added together, multiplied together, or multiplied by a positive number. Negative divided by a negative will be the greatest answer, because it will lead to a positive most of the time.

Solve (2/3)-(1/x)=5/6
Keith_Richards [23]
\frac{2}{3} - \frac{1}{x} = \frac{5}{6}   Multiply both sides by 3
2 - \frac{1(3)}{x} = \frac{5(3)}{6}   Simplify the numerators
2 - \frac{3}{x} = \frac{15}{6}   Multiply both sides by 6
12 - \frac{3(6)}{x} = 15   Simplify the numerator
12 - \frac{18}{x} = 15   Multiply both sides by x
12x - 18 = 15x   Subtract 12x from both sides
       -18 = 3x    Divide both sides by 3
        -6 = x      Switch the sides to make it easier to read
         x = -6

Check your answer by plugging -6 in for the x in the original problem:

\frac{2}{3} - \frac{1}{x} = \frac{5}{6}   Plug in -6 for x
\frac{2}{3} - \frac{1}{-6} = \frac{5}{6}   Change \frac{2}{3} to \frac{4}{6} so all denominators are the same
\frac{4}{6} - \frac{1}{-6} = \frac{5}{6}   Change \frac{1}{-6} to  \frac{-1}{6} for easier work
\frac{4}{6} - \frac{-1}{6} = \frac{5}{6}   Subtract the numerators (4 - (-1) )
\frac{5}{6} = \frac{5}{6}

So, x = -6 .

In the figure below, if angle ZYX measures 23 degrees, then arc XY measures 45 degrees.
ollegr [7]

Answer:

  FALSE

Step-by-step explanation:

Assuming ZY is a tangent, the measure of the arc will be twice the measure of the angle. If the angle ZYX is 23°, the measure of arc YX will be 46°.

The graph shows the data points in the table and the exponential regression model associated with the data ?
Ipatiy [6.2K]
From the graph, it is obvious that the trend is decreasing from 100 on day 2, to 1 on day 10. So, the answer could either be A or C. The question would be how fast is it decreasing? To illustrate this, let's find the difference of consecutive data:

100 - 26 = 74
26 - 6 = 20
6 - 2=4
2-1=1

It must not be an additive rate because there is no common difference. Let's illustrate if the trend is in multiplicative rate:

100/26 = 3.85
26/6 = 4.33
6/2 = 3
2/1 = 2

More or less, they have a common divider. Hence, the decreasing rate is in multiplicative rate. The answer is A.
