Y varies directly with square root of(x+5) ..
. y=4 when x = -1
find y when x=11​

y varies as √(x+5)

Step-by-step explanation:

y varies as √(x+5)

y= k√(x+5)

k is a constant connecting the two sides.

therefore

k=y/√(x+5)

k=4/√(-1+5)

k= 4/√4

k=4/2

k=2

Y when x=11

y=k√(x+5)

y=2√(11+5)

y=2√16

y=2*4

y=8

Kyle and Linda are earning together $32,000+$48,000=$80,000. Their monthly expenses are $3,500, which is yearly $3,500*12=$42,000. Plus they contribute 15% of their earnings to a retirement, that is: (15/100)*$32,000+(15/100)* $48,000=$4,800+$7,200=$12,000. At the end, they have $80,000 - $42,000-$12,000=$26,000. So, their net cash flow is positive and their plan for managing income is ok. They are also prepared for emergencies. With their savings and 15% contribution the have a good plan for retirement. The only thing that felts is a life insurance on Linda, so they can protect their assets.
