Answer:
A. Erica's graph is incorrect, because the slope should be greater than 9.5.
Step-by-step explanation:
Given
Clive:
Erica:
--- slope
--- y intercept
First, we need to determine the equation of Erica's earnings using
Where
m = slope = 9
b = y intercept = 0
So, the equation becomes
This implies that Erica earns 9 dollars per hour
For Clive:
This means that Clive earns 9.5 dollars per hour
From the question, we understand that Erica earns more than Clive.
<em>So, we can conclude that Erica's graph is incorrect because the slope must be greater than 9.5.</em>
<em>When the slope is greater than 9.5, then she earns more than Clive.</em>
Answer:
x=-3/19
y=39/19
Step-by-step explanation:
the equations can be written as the following system
If the second equation is multiplied by 3/2 it will become -18x+3y=9
If that equation is then subtracted with the first you will obtain the following
-19x=3, it means x=-3/19
The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
