The answer is D.
First, the equation to find the perpendicular line to a given line is $m_{2} = \frac{-1}{m_{1}}$ , where $m_{2}$ is the m value of the equation of the second line and $m_{1}$ is the m value of the equation of the first line.
Using this, we can find the slope of the equation of the perpendicular line:
$m_{2}$ = -1/(1/4)= -4
So now our options are slimmed down to C and D. We can tell which equation is correct by substituting the given coordinates
C: -6+2≠-4(-2+6), so this option is eliminated
D: -6+6=-4(-2+2), so this is our answer as both sides equal 0

The manager of a grocery store wants to determine the average amount of money spent at his store as it compares to the average d

dexar [7]

Given

Expenditures at Manager's Store; expenditures at Competitor's Store.

Find

a) average spent at each store

b) which store is better represented by the mean value

c) an explanation for the answer in ≥ 2 sentences

Solution

a) The sum of expenditures divided by the number of expenditures (15) is ...

... average for Manager's Store: $37.60

... average for Competitor's Store: $48.53

b) The expenditures at Manager's Store are well-represented by the mean (average).

c) The range of expenditures at Competitor's Store is significantly higher than at Manager's store, so a single number such as mean or median does not represent the data well. The expenditures at Manager's store are more compactly grouped around the mean and median, which are closer together, so the mean is a good representation of Manager's Store expenditures overall.

The FDA recommends that women who are pregnant avoid eating more than three 6.00 oz servings of bluefish per month because of th

kirza4 [7]

Answer:

5,562 x $10^{-6}$

Step-by-step explanation:

Firts, we need to find the maximum recommended amount of bluefish per month. Since the FDA recommends 3 servings of 6.00 oz each, the maximum amount would be:

the maximum amount of bluefish per month = $3 * 6.00 oz = 18.00 oz$

Since bluefish contains 0.309 ppm of mercury per 1x $10^{6}$ oz of fish, then:

0.309 oz mercury --------> 1x $10^{6}$ oz of fish

How many ( $y$ ) --------> 18.00 oz of fish

$y = \frac{18.00 oz of fish * 0.309 oz of mercury}{1 x 10^{6} oz of fish } = 0.000005562 = 5.562 x 10^{-6}$ oz mercury

3^x=1/9 What does x equal?

Nastasia [14]

Answer: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
