Answer:

a) = Slope of line AB = 1/2

<h2><em><u>Perpendicular = -2</u></em></h2>

<h2>b) <em><u>y = -2x + 6</u></em></h2><h2 />

Step-by-step explanation:

a) When it is perpendicular the answer will be positive if the initial value is negative. If it is a whole number, then the perpendicular number is going to be a fraction. The opposite applies.

b) Slope = -2x

   intercept = ?

y = -2x + b

0 = -6 + b

+6  +6

b = 6

<em><u>y = -2x + 6</u></em>

350 mL of water

Step-by-step explanation:

Solve the pair of simultaneous equations and leave the answer as a fraction in
Elena-2011 [213]

Answer:

x = 11/3 = 3 2/3

y = 13/3 = 4 1/3

Step-by-step explanation:

Here, we want to solve the system of equations simultaneously

x + y = 8

2x -3 = y

From the second equation, we have an equation for y

we can simply proceed to substitute this into the first equation

x + 2x - 3 = 8

3x - 3 = 8

3x = 8 + 3

3x = 11

x = 11/3

Recall;

y = 2x - 3

y = 2(11/3) - 3

y = 22/3 - 3

y = (22-3(3))/3

y = (22-9)/3 = 13/3
