Answer:

0

Step-by-step explanation:

We have the expression 3(x - 2) and we also know the value of x which is 2.

To solve for this, we need to substitute x with the value given :

3(x - 2) when x = 2

3(2 - 2)

Now follow PEMDAS and do the equation within the parenthesis.

2 - 2

0

3(0)

Now multiply 3 and 0 :

3 * 0

0

Answer:

see explanation

Step-by-step explanation:

Given

\frac{9}{a^2+9a+20} , \frac{7a}{a^2+11a+28}

Factor the denominators of both fractions

\frac{9}{(a+4)(a+5)} , \frac{7a}{(a+4)(a+7)}

The lowest common denominator of both fractions is (a + 4)(a + 5)(a + 7)

Multiply numerator/denominator of first fraction by (a + 7)

Multiply numerator/denominator of second fraction by (a + 5 )

\frac{9(a+7)}{(a+4)(a+5)(a+7)} , \frac{7a(a+5)}{(a+4)(a+5)(a+7)} , then

\frac{9a+63}{(a+4)(a+5)(a+7)} , \frac{7a^2+35a}{(a+4)(a+5)(a+7)}

Penny joined a yoga studio that charges a $25 membership fee and $45 each month. Assume y = total cost and x = number of months.
Firlakuza [10]

Answer:

y=45x+25

Step-by-step explanation:

y=45x+25

25 is a one-time fee so it is at the end. 45 is the monthly fee so it goes in front of x.

\dfrac{1}{22}\:\dfrac{\text{in}}{\text{hr}}

Step-by-step explanation:

The amount of time from 10pm to 7am is 9 hours. However, the time indicated is 7:10am. Since there are 60 minutes in an hour, 10 min is equal to 1/6 of an hour. Therefore, the total time that the water level of the pool decreased is 9\frac{1}{6} hours or \frac{55}{6} hours. To find the rate at which the water level decreased, we divide the change in the water (in inches) by the time it took to reach that level. So we write

rate of change = \dfrac{\text{change\:in\:height}}{\text{change\:in\:time}}

\:\:\:\:\:\:\:= \dfrac{\frac{5}{12}\:\text{in}}{\frac{55}{6}\:\text{hrs}}

\:\:\:\:\:\:\:=\dfrac{5}{12}\cdot\dfrac{6}{55}\:\dfrac{\text{in}}{\text{hr}}

\:\:\:\:\:\:\:= \frac{1}{22}\:\dfrac{\text{in}}{\text{hr}}
