Step-by-step explanation:
The given function is :

(a) To find f(9), put x = 9 in the above expression.

(b) To find f(x+7), put x = x+7 in the above expression.

(c) To find f(-x), put x = -x in the above expression.

Hence, this is the required solution.
Answer:
A
Step-by-step explanation:
To turn a fraction into a percent, you divide the numerator by the denominator.
8 divided by 9 = .8 repeated
To turn it into a percent, you move the decimal to the right 2 spaces.
.8 turns into 88.8 repeated
Then you round to the nearest hundredth
88.8 repeated rounds to 88.89.
Answer:
21/22 = repeating
60/120 = terminating
56/72 = repeating
11/121 = repeating
Step-by-step explanation:
i just know. fight me.
4x = 14y
y = 4/14(x)
y = 2/7(x) slope = 2/7
<span>-2x+7y=14
7y = 2x + 14
y = 2/7(x) + 2 slope = 2/7
parallel lines, slope is the same
both lines have slopes equal 2/7
