Answer:
8 1/2 hrs/wk
Step-by-step explanation:
3(1 1/2 hrs) plus
2(1 1/4 hrs) plus
2(3/4 hr)
The LCD here is 4. Convert 3(1 1/2 hrs) to 3(1 2/4 hrs), so that we now have:
3(1 2/4 hrs) = 3 6/4 hrs
+2(1 1/4 hrs) = 2 2/4 hrs
+2(3/4 hrs) = 6/4 hrs
-------------------------------------
5 14/4 hrs, or
5 + 3 2/4 hrs, or
8 1/2 hours/week
Answer:
A, B, and D
Step-by-step explanation:
Let's put all the answer choices in for x and y in both equations:
A) x = 0, y = 10
10 - 10 = 2 * 0 --> 0 = 0, which works
1/2 * 10 = 0 + 5 --> 5 = 5, which works
So, A is correct
B) x = 1, y = 12
12 - 10 = 2 * 1 --> 2 = 2 which works
1/2 * 12 = 1 + 5 --> 6 = 6, which works
So, B is correct
C) x = 2, y = -6
-6 - 10 = 2 * 2 --> -16 = 4, which doesn't work
So, C is incorrect
D) x = -5, y = 0
0 - 10 = 2 * -5 --> -10 = -10, which works
1/2 * 0 = -5 + 5 --> 0 = 0, which works
So, D is correct
Thus, the answers are A, B, and D.
Hope this helps!

Step-by-step explanation:
The graph of a <u>proportional linear relationship</u> is a line that <u>passes through the origin</u> (0, 0).
From inspection of the given tables, the <u>linear equations</u> for each table of points is:
- Table 1: y = x + 1
- Table 2: y = x/2
- Table 3: y = x + 2
- Table 4: y = 2x + 1
The only equation for which y = 0 when x = 0 is y = x/2 → Table 2.
Given points from Table 2:
To <u>graph the line</u>, plot the given points and draw a line through them (see attached).
