Answer:

<h3>a. True</h3>

\frac{1}{2} (c + 8) \: and \:  \frac{c + 8}{2}  \\ are \: equivalent \: expression

<h3>b. True</h3>

\frac{1}{2} (c + 8) \: and \:  \frac{1}{2} c + 4 \\ are \: equivalent \: expression

<h3>c. False</h3>

The \: only \: terms \: in \:  \frac{1}{2} (c + 8) \: are \:  \frac{c}{2}  \: and \: 4, \\ not \: c \: and \: 8

<h3>d. True</h3>

You \: can \: multiply \: c \: and \: 8 \: by   \\ \frac{1}{2}  \: in \:  \frac{1}{2} (c + 8) \: to \: find \: an \\ equivalent \: expression

If y ≠ 1, is x = 1 ? (1) x2 + y2 = 1 (2) y = 1 – x Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
stiv31 [10]

Answer:

Statements (1) and (2) TOGETHER are NOT sufficient.

Step-by-step explanation:

If y ≠ 1, is x = 1 ?

(1) x^2+y^2 = 1

(2) y = 1 – x

The two statements are not sufficient to assert this claim. The statement If y ≠ 1, is x = 1 only holds in the two statements if y=0 as seen below.

(1) x^2+y^2 = 1

x^2+0^2=1

x=1

(2) y = 1 – x

0=1-x

x=1

Every other value of y fails the condition. So a sufficient statement would have been:

If y ≠ 1, and y=0, is x = 1 ?

(1) x^2+y^2 = 1

(2) y = 1 – x

Y/3-a=b solve for y
madam [21]
Y/3-a=b

First multiply 3 on both sides
y/3-a=b
*3        *3
---------------
y-a=3b

Now add the a on both sides
y-a=3b
 +a    +a
----------------
y=3b+a

Your answer is 
Y=3b+a
