Answer:

The coordinates of the science lab is:

x = -14/3 , y = 1

Step-by-step explanation:

∵ P is (-8 , -1) and Q is (2 , 5)

∵ The point of the science lab is (x , y)

∵ The science lab point divided PQ at ratio 2 : 1 from Q (two thirds PQ)

∴ $x=\frac{m_{1}x_{p}+m_{2}x_{q}}{m_{1}+m_{2}}$

∴ $y=\frac{m_{1}y_{p}+m_{2}y_{q}}{m_{1}+m_{2}}$

∴ $x=\frac{2(-8)+1(2)}{1+2}=\frac{-14}{3}$

∴ $y=\frac{2(-1)+1(5)}{2+1}=\frac{3}{3}=1$

∴ The point of science lab = (-14/3 , 1)

Answer:

Option C is correct answer.

Step-by-step explanation:

We need to draw the graph of piece wise function

$f(x)\[ \begin{cases} -2-x & if\:x\leq 1 \\ -3+2x & if\: x>1 \end{cases}\]$

So, for drawing the graph, we will find values of f(x) for both the given equations.

First finding f(x) for $-2-x \:\: if\:x\leq1$

The value of x must be less than or equal 1

x f(x)

1 -3

0 -2

-1 -1

-2 0

-3 1

-4 2

The graph will start from closed circle because x ≤ 1

Now, finding values of f(x) for $-3+2x\: if\:x>1$

The value of x must be greater than 1

x f(x)

2 1

3 3

4 5

5 7

The graph will start from open circle because x> 1

Now, plotting these numbers we will get graph of Option C.

Option C is correct answer.
