Answer:
a. Chart (attached)
b. and c. graph attached
Step-by-step explanation:
a. We use the equation given to us and plug in the values of "x" that have been shown to find the corresponding values of y.
So, when x=0, 
when x=20, 
when x=40, 
b. The graph has been shown in a similar manner. All the three points of part a are connected to form the straight line y=6.75x+25. So, we have (0,25), (20,160) and (40, 295)
c. The y axis is the earnings in dollars and the x axis is the number of hours worked.
Answer:
The correct option is D) 43 items.
Step-by-step explanation:
As we know that total given time is ,
,
Out of which cashier spends 40 seconds to process the customer's payment.
So the remaining time = (126 - 40) = 86 secs.
And the remaining time is used to scan the item and so that we can calculate here the no items scan is = (86 ÷ 2) = 43.
Therefore we can say that 43 items are being purchased.
Answer:
21 inches Sq
Step-by-step explanation:
Area of triangle=1/2 * b * h
where Height= 7 in and Base = 3in + 3in= 6in
so 1/2*7*6=0.5*7*6=21
Find the negative reciprocal of the given line's slope in order to determine what the slope of the line will be.
-2/5 -> -5/2 -> 5/2
Your line now looks like this: y = 5/2x + b
Now, substitute the given point into the y and x variables and solve for b.
y = 5/2x + b
-3 = 5/2(2) + b
-3 = 5 + b
-8 = b
You are now done. The line is y = 5/2x - 8.
