Answer:
<u>C.</u>
Step-by-step explanation:
To find which table is correct, you first have to plot the graph. First, pick some easy points on the <em>X</em> axis to graph. Some of these points could be -4, 0 and 4. Now you need to fill in the equation.
<em>Y</em> = -1/2*-4 - 2 = 0
<em>Y </em>= -1/2*0 - 2 = -2
<em>Y</em> = -1/2*4 - 2 = -4
Now you can plot the points and draw your line. Once you have done this, you check each table and see if all the points match up. Doing so would give you answer C.

Answer: A = 216; B = 35
Step-by-step explanation:
Based on the information given in the question, we can then make it into a mathematical equation. This will be:
A + B = 251 ....... i
A - B = 181 ....... ii
From equation i,
A = 251 - B
Put the value of A into equation ii
A - B = 181
(251 - B) - B = 181
251 - B - B = 181
251 - 2B = 181
2B = 251 - 181
2B = 70
B = 70/2
B = 35
Since A = 251 - B
A = 251 - 35
A = 216
