Step-by-step explanation:
6 x 10 divided by 2 = 30
Answer:

Step-by-step explanation:
Hello, the Conjugate Roots Theorem states that if a complex number is a zero of real polynomial its conjugate is a zero too. It means that (x-4i)(x+4i) are factors of f(x).

The coefficient of the leading term is 1 and the constant term is -240 = 16 * (-15), so we a re looking for a real number such that.

We identify the coefficients for the like terms, it comes
a = -2 and 16a = -32 (which is equivalent). So, we can write in
.

The sum of the zeroes is 2=5-3 and their product is -15=-3*5, so we can factorise by (x-5)(x+3), which gives.

And we can write in 

Hope this helps.
Do not hesitate if you need further explanation.
Thank you
You are given the X value, replace x with 2 in the first equation to solve for y:
y=2x +3
y = 2(2) +3
y = 4+3
y = 7
Now replace y with 7 and x iwth 2 in the second equation and solve for k:
y = -x +k
7 = -2 +k
Add 2 to both sides:
9 = k
so k = 9
The point is given as k-2, which is 9-2 = 7, which is what y equals in the first equation.
K = 9

Answer:
H the range is all real numbers
Step-by-step explanation:
The arrows on the ends of the curve mean the curve extends to infinity. Then the domain (x-extent) is -3 to infinity.
The range (y-extent) is -infinity to infinity, <em>all real numbers</em>.
The appropriate description is ...
H The range is all real numbers
Answer:
2790
Step-by-step explanation:
38/100 * 4500 = 1710 get less than eight hours of sleep
4500 - 1710 = 2790 students
