Answer:

<h2><u>Question 8 </u></h2>

Multiply the following numbers using scientific notation: (2 x 10^3)(2 x 10^4).

(2 x 10^3) = 2*10*10*10 = 2000

(2 x 10^4) = 2*10*10*10*10 = 20000

2000*20000

=40 000 000

= $4 * 10^{7}$

<h2><u>Question 9 </u></h2>

Divide the following numbers using scientific notation: (4 x 10^2)/(1 x 10^3)

(4 x 10^2) = 4*10*10 = 400

(1 x 10^3) = 1*10*10*10= 1000

400/1000 = 0.4

= $4*10^{-1}$

<h2><u>Question 10</u></h2>

Perform the following calculation: (1 x 10^2)(2 x 10^3)/(1 x 10^2)

(1 x 10^2) = 1*10*10= 100

(2 x 10^3) = 2*10*10*10 =2000

100*2000 = 200 000

(1 x 10^2) = 1*10*10 = 100

200 000/100 = 2000

= $2*10^{3}$

To start, the equation has to be converted to slope-intercept form, or $y=mx+b$ . Start by subtracting x from both sides; $x-x+2y=4$ , $2y=4-x$ . Switch 4 and -x around to conform to the formula; $2y=-x+4$ . Then divide by 2 to isolate y; $y=-\frac{1}{2}x+2$ . This is the final equation. Because the slope of a line perpendicular is always the opposite reciprocal (i.e. The opposite reciprocal of 4 is $-\frac{1}{4}$ , the opposite reciprocal of $-\frac{1}{5}$ is 5) the opposite reciprocal of $-\frac{1}{2}$ is 2. So the equation of the line is $y=2x$ , and the answer is A.
