We can not really tell in this question as you dont know the equation that is being used for the domain and range relationship but overall one should know that:
The set of values of the independent variable(s) for which a function or relation is defined as the domain of a function. Typically, this is the set of x-values that give rise to real y-values.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
If you pay $400 down, plus $80 for the next 12 months, that means you're paying (80*12)+400 which is equal to $1360. You're saving $100 by paying the entire total up front.
Step-by-step explanation:
Note the system of equation, PEMDAS. First, you solve parenthesis, then multiplication, then subtraction.
In this case, solve each of the expression given to us. Remember that parenthesis is first:
(12 - 23) * 2 = (-11) * 2 = - 22
12 - (3 * 2) = 12 - (6) = 6
- 22 ≠ 6
~
20=3x-1
move -1 to the other side
sign changes from -1 to +1
20+1=3x-1+1
20+1=3x
21=3x
divide both sides by 3 to get x by itself
21/3=3/3x
Cross out 3 and 3, divide by 3 and then becomes 1*1*x=x
21/3=x
Answer:
x=7
A = 4/15
B = 6/15
