Answer:
Danielle earns $1.20 more than Mackenzie (per hour)
Step-by-step explanation:
To find out how much money per hour each person earns, you would divide the earinings by the number of hours;
Danielle: $36.80/4 = $9.20 per hour
MackKenzie: $50.40/6 = $8.40 per hour
To find out how much extra Danielle earns, you would subtract 8.40 from 9.20;
9.40 - 8.20 = $1.20
Thus, Danielle earns $1.20 more than Mackenzie per hour.
Answer:
c is greater than or equal to -1.
Step-by-step explanation:
Subtract 3 from both sides, divide by 5.
I have attached the work to your problem below.
I hope this helps.
If you know that b=0, then ab=bc doesn't tell you anything about
'a' or 'c', because no matter what they are, it's always true.
Answer:
z = -1
Step-by-step explanation:
You must first start out by adding 19 to both sides to isolate the variable z, which results in:
2z = -2
Now, you can just divide by two on both sides to get z completely on its own, which gives you:
z = -1
Hope this helped somewhat! :D
Answer:
Shift 6 units right.
Step-by-step explanation:
Easiest way to answer this question is to plot the two graphs:
Let's plot these graphs and analyse each graph.
Lets take the graph of 
that is attached.
We can clearly see that graph intersects x axis at x=0 and then essentially looks like y=x is mirrored by the y axis.
Now when we look at the 
that is attached,
We can see that graph intersects x axis at x=6 and is a composite graph of and its mirrored graph by y=6.
We can clearly see that graph has moved 6 units to the right.
