Part 1
<h3>Answer: 13</h3>
---------------------
Explanation:
We'll replace every copy of x with -3. Then use PEMDAS to simplify.
f(x) = -2x+7
f(-3) = -2(-3)+7
f(-3) = 6+7
f(-3) = 13
===========================================================
Part 2
<h3>Answer: -11</h3>
---------------------
Explanation:
We work backwards in a sense compared to what part 1 did. Instead of finding f(x) based on x, we determine what x must be for a given f(x).
We'll replace f(x) with 29 and solve for x like so
f(x) = -2x+7
29 = -2x+7
-2x+7 = 29
-2x = 29-7
-2x = 22
x = 22/(-2)
x = -11
Note how if you replaced x with -11, we'd get,
f(x) = -2x+7
f(-11) = -2(-11)+7
f(-11) = 22+7
f(-11) = 29
which helps confirm we have the correct answer.

Fourth Divided and I have a meeting with my friend 26 on Friday divided by 33 times by + 4
Answer: 95
Answer:
Y=2x+0
Step-by-step explanation:
First you have to find the slope of the graph or the rise over run, which in this case is 2
Then you have to find the y intercept, which is zeroSo the rule for thos graph is y=2x+0.
To double check our work take a random point on x axis. I chose the point 1,2
fill in the formula and you should get 2(1)+0=2 and therefore this Formula is correct
