The answer to number 1. is 7a+1 if your adding or simplifying.
And number 2 would be 9p^3 - 27p^2 + 48p
Answer:

Step-by-step explanation:
We will use the point slope formula: 
We will start by finding the slope(
).
The formula for slope is

So if we just choose 2 random points on the line:
I choose (0,2) and (4,1), we get:

That's our slope.
Next we need to find the y-intercept(
). We can find that by looking at the graph. It is where x=0. So in this case y=2 when x=0.
So in point-slope form the equation is:

The sum of 3.4a + -3.5a is..
3.4
+-3.5
-------
- .1a
It is negative because -3.5 is grater than positive 3.4
Answer:
y = 9 * bˣ
Step-by-step explanation:
y = a * bˣ
9 = a * b⁰ = a * 1
a = 9
4608 = 9 * b³
b³ = 512
b = 8
y = 9 * bˣ
Answer: i=<u> 5 </u>
6
Step-by-step explanation:
(-3+3i)+(-2+3i)
-3+3i-2+3i=0
3i+3i=3+2
6i=5
i=<u> 5 </u>
