Answer:
CANT ZOOM IN ITS SIDEWAYS CANT SEEEEE XD
Step-by-step explanation:
We are given
selling price of one flower is $0.50
so, 
Let's assume
she sold 'n' flowers to get $20
so, total amount she get after selling 'n' flowers is


This is supposed to be $20
so, we can set it equal to 20

now, we can solve for n
we get

we are given
she makes $6.00 on every $20 worth sold
so, we can find cost of 40 flowers is 20-6
total cost is 14
or cost of 40 flowers is $14
now, we can find cost of one flower


so, cost of each flower is 35 cents...............Answer
Answer:
Perpendicular
Step-by-step explanation:
2x - y = -7
2x + 4y = 2
-y = -2x - 7
4y = -2x + 2
y = 2x + 7
y = -1/2x + 1/2
Cannot be:
Parallel because the slope would otherwise be the same.
Same line because the equation is not proportional
So, they are perpendicular because a perpendicular line would be a negative and a reciprocal of the current line
Three and seventy-five hundredths.
Hope I helped! :P
The type of graph that would allow us to quickly see how many students were treated would be a Bar graph.
