Answer:
Step-by-step explanation:
Solve the y
y -3 = 1/2(x + 2)
y = 1/2(x + 2) + 3 Add
Pick points that you wish to substitute for x values.
x = 0 x = 2 x = 4
y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3
y = 1/2(0 + 2) + 3 y = 1/2(2 + 2) + 3 y = 1/2(4 + 2) + 3
y = 1/2(2) + 3 y = 1/2(4) + 3 y = 1/2(6) + 3
y = 1 + 3 y = 2 + 3 y = 3 + 3
y = 4 y = 5 y = 6
Locate the following point on graph (x, y); (0, 4), (2, 5), (4, 6)
Answer: C
Explanation: Let's find each equation without any inequalities first. We have a dotted line at y = 1, so we can already remove A and B. Now, a dotted line represents exclusivity and hence; it should not include the = sign.
Thus, by elimination, the answer must be C.

Answer: 12y</h3>
=====================================================
Explanation:
4y is the middle value, or second value.
This means 4y-1 is the first value since it is immediately before 4y
Also, we know that 4y+1 is the value just after 4y
The order of the terms is: 4y-1, 4y, 4y+1
Add up those three expressions and simplify
(4y-1) + (4y) + (4y+1)
4y-1 + 4y + 4y+1
(4y+4y+4y) + (-1+1)
12y+0
12y
The three terms combine to 12y.
Answer:
16
Step-by-step explanation:
40x 6 =u x 15
240=u x 15
U = 240÷15
U = 16
