A:
An independent variable could be how long she works. (Well it's not really independent I guess... Sorta depends.)
A dependent variable could be how much money she makes, depending on how long she works.

B:
Umm, like:
(1, 7)
If 1 was how many hours she worked and $7 is how much money she made, and therefore x would be how many hours she worked and y would be how much total money she made.
(2, 14)
(3, 21)

C: An equation would be 7x = y.

Given f(x) = √(x-3) , what is the positive value of f(12)?

Shalnov [3]

Answer:

Step-by-step explanation:

Given

f(x) = $\sqrt{(x-3)}$ , then

f(12) = $\sqrt{12-3}$ = $\sqrt{9}$ = ± 3

There are 2 values 3 and - 3

Which of the expressions below has a 1 in the thousandths place of the sum? Select all that apply. A) 32.474 + 16.577 B) 23.452

Paraphin [41]

Answer:

A) 32.474 + 16.577

= 49.051

C) 19.213 + 4.578

= 23.791

Step-by-step explanation:

Place value may be defined as the positional system of a notation where the position of any number with reference to the decimal point determines the value of that number.

A) 32.474 + 16.577

= 49.051

B) 23.452 + 31.561

= 55.013

C) 19.213 + 4.578

= 23.791

D) 8.128 + 9.192

= 17.32

We have to find the expression which contains 1 in the thousandths place in the sum.

We know after the decimal point, the place value are designated as tenths, hundredths, thousandths, and so on.

Therefore, A). 49.051 and C). 23.791 has a place value of 1 in its thousandths place.

Line A is perpendicular to line B. The slope of line A is -1/9 what is the slope of line b?

Pani-rosa [81]

$\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}}
{\stackrel{slope}{-\cfrac{1}{9}}\qquad \qquad \qquad \stackrel{reciprocal}{-\cfrac{9}{1}}\qquad \stackrel{negative~reciprocal}{+\cfrac{9}{1}}\implies 9}$
