Answer:
dy/dx = -1/
Step-by-step explanation:
y = 1/x
dy/dx = d/dx(1/x)
=> dy/dx = d/dx(
)
=> dy/dx = -
=> dy/dx = -1/
Answer: The median of the upper half of a set of data is the upper quartile ( UQ ) or Q3 . The upper and lower quartiles can be used to find another measure of variation call the interquartile range . The interquartile range or IQR is the range of the middle half of a set of data.
Step-by-step explanation:
If it is discounted 25%, then u r actually paying 75%
0.75(119) = 89.25 (without tax)
sales tax = 7 1/2% = 7.5% = 0.075
89.25(1.075) = $ 95.94 <===
The answer is the last one
Answer:

Step-by-step explanation:
Slope intercept form of a line is given by:

Where
m is the slope and b is the y-intercept
Given slope is 
We can write:

Now to find b, we replace x with -3 and y with -4, given, so we have:

So, the equation is:

Now,
The standard form is given by:

So, we take x and y to left side and the constant to right side. Rearranging, we get:

The first answer choice is right.
