The sandwich cost 2.25 meaning that that would be our slope since the price can go higher with every sandwich you buy.. and it will be negative because you will be taking away that sum to your five dollars.. so we have y=-2.25 +5 it has plus five because it is how much you had in the first place.. so lets test it, lets say you buy 2 sandwiches. you will put 2 in for x and solve it.. -2.25(2) +5 multiply -4.5+5 and you get .5 this lets you see first how much you will spend and what will be left out
Hope i helped
With y-x=0, add x to both sides to get y=x.
Now you can substitute either x or y
7x-9x=8 or 7y-9y=8 which is the same thing
-2x=8 or -2y=8
x=-4 or y=-4
Hope this helped!
Answer:
7 / 30
Step-by-step explanation:
This is a selection without replacement probability :
Total boxes = 16
With money = 3
With traveling prices = 5
Empty = 8
P(choosing 2 empty boxes) :
P(empty) * P(empty)
P(empty) = Number of empty boxes / total number of boxes
First pick = empty
P(empty) = 8 / 16 = 1/2
Without replacement :
Second pick = empty
P(empty) = 7 / 15
P(choosing 2 empty boxes) = 1/2 * 7/15 = 7 /30
Answer:
The area of the rectangular area is (1400w-w²) square yards.
Step-by-step explanation:
Given that,
David has available 2800 yards of fencing. He wants to enclose a rectangular area.
Assume that, the length and width of the rectangular be l and w respectively.
The perimeter of the rectangular area is
=2(length+ width)
=2(l+w)
So,
2(l+w)= 2800
The area of the rectangular area is = length× width
=l×w
=(1400-w) w
=(1400w-w²) square yards.
