It is not reasonable because the decimal placing on the 4.23 is greater then the one on 413. (2 is bigger then 1). When dealign with decimals it is important to remember that if the numbers before the decimal are the same for both numbers you need to look at the first decimal as though it's the first number. so we know 4 and 4 are the same. Next we look at the .23 and .13. We know that the number 2 is bigger then 1 so it's safe to say that 4.23 is larger then 4,13.

In this question, you're solving the given function.
In this case, you would plug in "-3" to the x variable, then solve.
Solve:
f(x) =4(-3) + 5
f(x) = -12 + 5
f(x) = - 7
When you're done solving, your answer should be -7.
Answer:
f(x) = - 7
Answer:
Step-by-step explanation:
This is a very interesting problem. We are given the slope and one point, which makes this funner than normal ;)
Filling in the slope formula with what we are given:
which simplifies to
Since slope is rise over run, the rise number is -3; the run number is 5. That means that the equation to find the y coordinate comes from -3 = y - 2; the equation to find the x coordinate comes from 5 = x + 3 (keep in mind that you could have made the x coordinate the negative one; it doesn't matter. You will get the same answer regardless...promise).
Solving for y:
-3 = y - 2 and
y = -1
Solving for x:
5 = x + 3 and
x = 2
Let's check those coordinates in the slope formula and see if our slope is in fact -3/5:
so we're all good!
The coordinates of B are (2, -1)
AB + BC = AC <em>Segment Addition Postulate</em>
(x + 10) + (x + 14) = 22 <em>Substitution</em>
2x + 24 = 22 <em>Simplify (added like terms)</em>
2x = -2 <em>Subtraction Property of Equality</em>
x = -1 <em>Divison Property of Equality</em>
Answer: x = -1
