Answer:
b
Step-by-step explanation:
Answer:
It is a prime number.
Step-by-step explanation:
A prime number is a number that can only be the product of 1 and itself. 17 can only be multiplied by 1 and 17, so it is prime.
Answer:
D
Step-by-step explanation:
Literally substitute one of the points (4,2), using some common sense, the x is larger than the y, so it can't be A or B (makes 4 larger) and really just pur 4 in option C, it won't be a pretty nice number. So the only option is D.
Answer:
1.1 : C - x^2 + x - 2
1.2 : A - 4a^2 - 6b^2 + 12
Step-by-step explanation:
When we have the expression p(x) - q(x), we can substitute those functions in:
(x^2 + 2x - 5) - (x - 3)
We can distribute:
x^2 + 2x - 5 - x + 3
and then combine like terms(2x & -x, -5 & 3)
x^2 + x - 2
This is the same as C.
We can start by distributing:
a^2 - 2b^2 + 3 - 4b^2 + 5 + 3a^2 + 4
Now, we can combine all the a^2 terms(a^2 & 3a^2):
4a^2 - 2b^2 + 3 - 4b^2 + 5 + 4
Then, we can combine the b^2 terms(-2b^2 & -4b^2):
4a^2 - 6b^2 + 3 + 4 + 5
and lastly, all the constants:
4a^2 - 6b^2 + 12
This aligns with option A
F(5) would be the y value of where the line is when it is at x 5
The line crosses at -6.5
F(5) = -6.5
