Answer:
2 dozens, $41
Step-by-step explanation:
Given data
Man Street Florist charges
$18 for a dozen roses and a
$5 delivery fee
let the number of dozens be x
and the total charge for x dozens be y
hence
y= 18x+5--------------1
Blooms and Bouquets
charges $20 for a
dozen roses and a $1
delivery fee.
let the number of dozens be x
and the total charge for x dozens be y
hence
y= 20x+1 -------------2
Equate 1 and 2 we have
18x+5=20x+1
20x-18x= 5-1
2x= 4
x= 4/2
x= 2
Hence the number of dozens is 2
the cost is (put x= 2 in eqn 1 or 2)
y= 20(2)+1
y= 40+1
y= $41
3(-5) + 4(2)
= -15 + 8
= -7
Answer:
y= x squared.
Step-by-step explanation:
When graphed, the parabola only has an x-intercept at (0,0). Since a root is another word for an x-intercept, it only has one root.
I hope this helps, and I hope you have a good day.
Y=1x+2 (you don’t have to write the 1 in front of the x so you can write it as y=x+1)
