Answer:
x=8
y=16
Step-by-step explanation:
2x+2y=48
3x+y=40
Ther is many ways to solve this, one of them is clearance:
WE CLEAR AN UNLOCKED (X) AND REPLACE IT IN THE OTHER
x= (40-y)/3
2[(40-y)/3] +2y=48
(80-2y)/3 +2y=48
(80-2y+6y)/3=48
80+4y=48(3)
4y=144
y= 144/4
y=16
x=(40-y)/3
x=(40-16)/3
x=24/3
x=8
4 3/4 + 2 1/2 = 4 3/4 + 2 2/4 = 6 5/4 = 7 1/4 = 6 hours and 15 minutes.
Answer:
y = - 24/7
Step-by-step explanation:
Hope this helps!
Range is ouutput from inputing the input
domain is input
f(x)=4x
28=4x, x=7
30=4x, x=15/2
32=4x, x=8
34=4x, x=17/2
36=4x, x=9
domain is {7,15/2, 8, 17/2, 9}
