Can you help me on this one please

Vera_Pavlovna [14]

Answer: x ≥ 1307

Explanation:

First, write the formula:
monthly fee: $14
minute rate: 7¢ or $0.07
total charge: $105.49
.07x + 14 ≥ 105.49 (the sign is this way because they said this price was the least she had been charged for a month.
You can solve for x just like you would in an equation by making the ≥ sign an equal sign
.07x + 14 = 105.49
- 14 -14
.07x = 91.49
÷ .07 ÷ .07
x = 1307 minutes
since you didn't divide by a negative number, the inequality sign stays the same:
x ≥ 1307

Graph the given relation or equation and find the domain and range. Then determine whether the relation or equation is a functio

KiRa [710]

Domain: $\{3.3,-1.7,-4.7\}$

Range: $\{5.3,3.3,-2.7\}$

The relation is not a function.

Explanation:

The coordinates $(3.3,5.3), (-1.7,5.3), (-4.7,3.3), (-4.7,-2.7)$ are plotted in the graph. The image of the graph is attached below.

The domain of a relation is the set of all x-values for which the function is well defined. Thus, the domain are $\{3.3,-1.7,-4.7\}$

The range of a relation is the set of all y-values obtained by substituting the values for x in the function. Thus, the range are $\{5.3,3.3,-2.7\}$

The relation $(3.3,5.3), (-1.7,5.3), (-4.7,3.3), (-4.7,-2.7)$ is not a function since, -4.7 has two different y-values. By definition of function, the function cannot have two different y-values for the same x-value.
