Answer:
-3
Step-by-step explanation:
Given the function f(x) = -(-x)
we want to evaluate f(-3)
What we do simply here is substitute the value of -3 for x in the equation
That would be ;
f(-3) = -(-(-3)) = -(3) = -3
Answer:
A
Step-by-step explanation:
The average rate of change is the change in attendance over change in time.
Δy / Δx
(333.7 - 298.3) / (5 - 2)
11.8
So the average rate of change is an increase of 11.8 thousand people per year.
Each of these roots can be expressed as a binomial:
(x+1)=0, which solves to -1
(x-3)=0, which solves to 3
(x-3i)=0 which solves to 3i
(x+3i)=0, which solves to -3i
There are four roots, so our final equation will have x^4 as the least degree
Multiply them together. I'll multiply the i binomials first:
(x-3i)(x+3i) = x²+3ix-3ix-9i²
x²-9i²
x²+9 [since i²=-1]
Now I'll multiply the first two binomials together:
(x+1)(x-3) = x²-3x+x-3
x²-2x-3
Lastly, we'll multiply the two derived terms together:
(x²+9)(x²-2x-3) [from the binomial, I'll distribute the first term, then the second term, and I'll stack them so we can simply add like terms together]
x^4 -2x³-3x²
<u> +9x²-18x-27</u>
x^4-2x³+6x²-18x-27
Here's what we know: Coach Posey has $10,000, and will be hypothetically investing in Bryant Bank for 12 years at 5% simple interest.
We can calculate the interest with the formula I = prt, where I is the interest, p is the principal (starting amount), r is the rate, and t is the amount of time.
I = $10,000(0.05)(12)
I = $10,000(0.6)
I = $6,000
He started with $10,000, and earned $6,000 interest, so he has $10,000 + $6,000, or $16,000.
No you don't need to use and specific calculator to find the slope you will use the formula y=mx+b
