J=john's age now
s=sam's age now
j=3 times s
j=3s
in five years (j+5,s+5)
j+5=2 times (5+s)
j+5=2(s+5)
j+5=2s+10
subtract 5 from both sides
j=2s+5
use other equation
j=3s
j=2s+5
subsitute
3s=2s+5
subtract 2s
s=5
sam=5
j=3s
j=3 times 5
j=15
john=15
sam=5
Answer:
Step-by-step explanation:
there is a linear relationship
from the table, x changes by +6, y changes by -3 every time
so that means the slope is constant i.e. its a straight line
slope=(y2-y1)/(x2-x1)=-3/6
= -1/2
take the 1st pt, ( 1, -4 )
(y-(-4)) = slop * (x-1)
y+4 = -1/2*(x-1)
ans is A
Answer:
C
Step-by-step explanation:
12*2.5=30
3.5*2.5=8.75
8.75*2=17.5
30*2=60
17.5+60=77.5
