#2.

a) 1/4m + 3 = 2

1/4m = -1

m = -4

b) 4y - 3(y + 8) = 12

4y - 3y + 24 = 12

y = -12



For #10, letter b. Do the same thing you did with letter a.
The equation is already given.
You have your y-intercept: -8, and your slope: 3/1.

These two create two different points you can add to your data table.

(0, -8) and (1, 3)

y:-8, 3
x: 0, 1

How are discontinuities and zeros created in rational expressions, and in what ways can they be accounted for graphically?
pshichka [43]

Discontinuities can be recognized by observing at asymptotes. An asymptote is a line where the space between the curve and the line go to zero as single or both of the x or y coordinates inclines to infinity. Graphically, they're holes in the graph. Zeroes are points wherever the graph hits the x axis.

lisabon 2012 [21]

Answer:

Option 4

The term that represents the amount of time that the money is accruing interest is 'x'.

Step-by-step explanation:

Given : The function below represents the annual interest Alexander earns on a savings account.

f(x)=500(1+0.02)^x

To find : Identify the term that represents the amount of time that the money is accruing interest ?

Solution :

The general annual interest formula is A=P(1+r)^t

Where, A is the amount

P is the principal

r is the interest rate

t is the time

The annual interest Alexander earns on a savings account is

f(x)=500(1+0.02)^x

Comparing with general formula,

t=x

The term that represents the amount of time that the money is accruing interest is 'x'.

Therefore, Option 4 is correct.
