Answer:
See the graph of the given linear equation shown below.
Explanation:
Given the linear equation : x+y = -2
We make a table for values of x and y;
x y = -2-x
0 -2
-2 0
1 -3
Now, plot these three points (0, -2) , (-2, 0) and (1, -3) on the coordinate plane.
You can see the graph as shown below.
Answer:
a) 41
b) -31
c) 25/3
Step-by-step explanation:
The instructions explain what a function is pretty clearly.
Basically, whatever is in the parentheses next to the , you plug in to the expression that is the function.
ex:
Okay, onto the problems:
a)
First, plug in 14, since that is given:
and solve.
So, 41 is the answer to a.
b) Do the same thing you did in problem a. Plug in the number inside the parentheses and solve.
-31 is the answer to b.
c) For this problem, you have to do a bit of algebra.
First, take the base function f(x):
Then, set f(x) = 24:
and solve by isolating x.
25/3 is the answer to c.
Add every decimal, then divide by 14 (two weeks, 7 days, total of 14 values), and the closest you get is 0.42.
