Answer:
3.38
Step-by-step explanation:
x + y + z = 16.9
x = 2y
y = z
y=y
2y (x) + y(y) + y(z) = 16.0
5y = 16.9
y = 3.38
You start by plugging in x=-2 into f(x)
f(-2) = 3^-2
Which gives you
f(-2) = 1/3^2 since negative exponents change the number to a dividend.
Then you square the 3
f(-2) = 1/9 or .111 repeating
Hi, I believe you are looking for a multiplication answer -8*3=-24
Answer:
A
Step-by-step explanation:
Here, we want to choose the option that best suit the question.
Let’s consider the cases individually;
for (x-6) = 0
we have a root at x = 6 which is a real root
Secondly
x^2 + 8x + 16 = x^2 + 4x + 4x + 16 = 0
That would be;
x(x + 4) + 4(x + 4)
(x + 4)(x + 4) = 0
Thus x = - 4 twice
So the roots of the given equation would be;
6 , -4 , -4
Which is 3 real roots but only 2 real distinct roots
