Answer:
Step-by-step explanation:
Given:
Cameron earns $7 per hour at her after school job.
The total amount she earns varies directly with amount of time she works.
If represents the amount of time she works in hours, and represents the total amount she earns in dollars.
We have,
∝
Thus,
where is constant of proportionality.
Now, here we are given with the rate at which she earns which $7 per hour, so the proportionality of constant would be =7.
So, the direct equation for the amount of money she earns can be given by:
(Answer)
Answer: 3:08
Step-by-step explanation:
They started riding at 2:47 and reached the soccer field 21 minutes later.
The time they go to the field is therefore:
= 2:47 + 21 minutes
= 3:08
<em>Adding time:</em>
<em>First find out the number of minutes needed to take 2:47 to 3:00:</em>
<em>= 60 minutes in an hour - 47</em>
<em>= 13 minutes </em>
<em>Then remove the 13 minutes from the 21 minutes of riding:</em>
<em>= 21 - 13</em>
<em>= 8 minutes </em>
<em>Add this 8 to 3:00:</em>
<em>= 3 + 8</em>
<em>= 3:08</em>
The graph represents the line x = 3.
Since there is more than one y-value for the one x-value provided, this graph is not a function.
The range is infinite, as there are no limits shown on the graph, and the slope is undefined.
The domain is only 3, since the only x-value on the graph is 3.
Based on this information, the statements that are true will be:
C. This graph is not a function because the value x = 3 is assigned to more than one y-value.
E. The equation of this line is x = 3.
(Note that D says the graph <em>is a function</em>. The graph isn't a function, as there is more than one y-value for x = 3.)
Answer:
?=12
Hope this helps!
Step-by-step explanation:
2*3=6
2*9=18
6+18=24
3+9=12
24-12=12
?=12
