A function is a relationship between two sets of variables, the domain and the range, in which each value of the independent variable (the domain) is associated with exactly one value of the dependent variable (the range). Therefore, a graph is not of a function when there are two different values of y for a single value of x.

Answer:

The correct option is 4.

Step-by-step explanation:

A relation is a function if and only if for each value of x, there exist a unique value of y.

It means if a relation contains (x,y_1) and (x,y_2), where y_1\neq y_2, then the relation is not a function.

We need to find a reason why the graph is not a function.

The reason is "it is not a function because there are two different y-values for the single x-value".

Therefore the correct option is 4.

for this job , Hayden earns an hourly rate of $30. For each hour he works over 40 hours, he earns 1.5 times his regular hourly r
Dominik [7]
Hayden's hourly rate is $30
Extra hour rate is 1.5×30=$45
given that he earned $2175 by working 40 regular hours, the number of overtime hours he worked will be given as follows;
let the number of overtime be x
hence total amount earned will be:
(40×30)+(45×x)=2175
1200+45x=2175
45x=2175-1200
45x=975
solving for x we get
x=975/45
x=65/3=21 2/3 hours

Solve the simultaneous equation 2x+5y=6 and 5x-2y=9​
Ilia_Sergeevich [38]

Answer:

x = \frac{57}{29} \ , \ y = \frac{12}{29}

Step-by-step explanation:

                            2x + 5y = 6     --------( 1 )

                            5x - 2y = 9     --------( 2 )

                        _____________

     ( 1 ) x 5 =>     10x + 25y = 30   -----------( 3 )

     ( 2 ) x 2 =>    10x - 4y = 18       ----------- ( 4 )

                       ______________

    ( 3 ) - ( 4 ) =>    0 +  29y = 12

                                   y = \frac{12}{29}

Substitute y in ( 1 ) =>

                            2x + (5 \times \frac{12}{29}) = 6\\\\2x + \frac{60}{29} = 6\\\\2x = 6 - \frac{60}{29}\\\\2x = \frac{174 - 60}{29}\\\\x = \frac{114}{29 \times 2}\\\\x = \frac{57}{29}
