The given function is a linear function that decreases as the value of the
input <em>x</em> increases.
- The value of f(10), given f(x) = 9 - 2·x is option <u>A. -11</u>
Reasons:
The given function is f(x) = 9 - 2·x
The output of the function is the value of f(x) for a given input <em>x</em> of the function.
The input value, <em>x</em> is substituted into the function to obtain the output value, f(x).
Given that the input, x = 10
We have;
f(10) = 9 - 2×10 = -11
Therefore, the correct option for f(10) is <u>A. -11</u>

Answer:
2/11
Step-by-step explanation:
6/33 simplified to lowest terms is 2/11.
Y = 5 - 3x....so sub in 5 - 3x for y in the other equation
5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1
now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2
check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)
so ur solution is (1,2)
8!in is the initial value at 0 days which represents b=8
The rate of change is 3in per day, this rate is the slope m = 3
Now substitute
y = 3x + 8
