Answer:
D
Step-by-step explanation:
out of the choices
A) 2x-y=-2
3x+2y=-10
B) x+4y=3
2x+5y=3
C) 2x+3y=5
x-4y=-14
D) 3x+4y=15
x+y=5
only the system in D has a solution of x=5 and y=0
solve by substitution x+y=5 so x=5-y
plug into the other equation so 3(5-y)+4y=15
distribute 15-3y+4y=15 then minus 15 on both sides and combine like terms
so y=0 then put that value back into the other equation
so x+y=5 equals x+0=5 so x=5 this means the solution to the system of equations is the point (5,0)
Hope this helps! :)
Answer:
Step-by-step explanation:
Total members = 14
Each member:
Peaches = 3
Pint of cream = 1
Cost
Peaches = x cent
Pint of cream = 46 cent
46 cent = $0.46
Cost per member = 3(x cent) + 0.46
= 3x cent + 0.46
Total cost for all members = 14(3x cent + 0.46)
= 42x cent + 6.44
