135. To get from one number to the next, you have to divide by 3. Since multiplication is the opposite of division, you have to multiply the second number in the sequence, 45, by 3 in order to get the first number, which is 135.

Passes through (1, -1) and (2,0)

Sauron [17]

Answer:

y = x - 2

Step-by-step explanation:

1. Find the slope - change in y/change in x

$\frac{0-(-1)}{2-1}$ = 1

Slope is 1

2. Find y-intercept

y = x + b

Substitute a point (2,0)

0 = 2 + b

b = -2

3. Put the equation together

y = x - 2

As a water quality assurance employee for your local Aqua America, Inc., branch, you record a drop in water levels from 28 feet

ioda

So, it went down from 28 to 7, meaning 28 - 7 = 21, 21 feet then.

now, if we take 28 to be the 100%, what is 21 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
28&100\\
21&p
\end{array}\implies \cfrac{28}{21}=\cfrac{100}{p}\implies p=\cfrac{21\cdot 100}{28}$
