Can somebody help me out please !

Agata [3.3K]

Answer:

Part A

5yr old boy.

Y=-(1/8)x+113/8 x=5

Y=-5/8+113/8=(113-5)/8=108/8

Y=13.5 hrs

Yes the estimated value of sleep by this function is reasonable as it is close to childhood more sleep is likely.

Part B

20yr old boy.

Y=-(1/8)x+113/8 x=20

Y=-20/8+113/8=(113-20)/8=93/8

Y=11.63 hrs

No the estimated value of sleep by this function is not reasonable as the normal sleep of 7-8 hrs is enough for adults.

Solve the simultaneous equation <br> 2x-5y=9<br> 3x+4y=2

Dmitriy789 [7]

Answer/Step-by-step explanation:

2x-5y=9

Add 5y to both sides of the equation.

2x=9+5y

Divide each term by 2 and simplify.

Divide each term in 2x=9+5y by 2

$\frac{2x}{2} =\frac{9}{2} +\frac{5y}{2}$

Cancel the common factor of 2.

Divide x by 1.

$x=\frac{9}{2} +\frac{5y}{2}$

$y=\frac{-9}{5} +\frac{2x}{5}$

----------------------------------------------------------------------------------------------------------------

3x+4y=2

Add 4y to both sides of the equation

3x=2+4y

Divide each term by 3 and simplify.

Divide each term in 3x=2+4y by 3.

$\frac{3x}{3} =\frac{2}{3} +\frac{4y}{3}$

Cancel the common factor of 3.

Divide x by 1.

$x=\frac{2}{3} +\frac{4y}{3}$

$y=\frac{-1}{2} +\frac{3x}{4}$
