Solve the equation for r by finding a,b, and c of the quadratic then applying the quadratic formula.
Answer:
Choice D
Step-by-step explanation:
For this one I would find if the point lands on the line.
<em><u>Choice A:</u></em>
What we have to do is to plug in -4 for x and 4 for y.

The point is not on this line so this cannot be it.
<em><u>Choice B:</u></em>
We pug what we know again.

The point is not on this line so it can't be it.
<em><u>Choice C:</u></em>
We pug in what we know again.

The point is not on this line so it can't be it.
The next one has to be it, but we'll check it just in case.
<em><u>Choice D:</u></em>
We plug in what we know again.

The point is on this line so this is the line.
Answer:
The value of f(g(3) = 1,008
Step-by-step explanation:
<u>Step:-1</u>
Given f(x) =
and g(x) = 3x+9
h(x) = 12+x
Given g(x) = 3x+9
put x =3
g(3) = 3(3)+9
<u> g(3) = 18</u>
<u>Step :-(2)</u>
f(g(3)) = f(18)
f(g(3) = 3(18)^2 +2(18) (since f(x) =
)
= 1,008
<u>Final answer</u>:-
The value of f(g(3) = 1,008
Answer:
1. is not
2. increase
3. remain the same
Step-by-step explanation:
Answer: A: 3x^2y^(3/2)
Step-by-step explanation:
This can be written as
(81*x^8*y^6)^(1/4)
Then multiply each exponent by (1/4):
81^(1/4)*x^(8(1/4))y^6(1/4))
81^(1/4) = 3
x^(8(1/4)) = x^2
y^6(1/4)) = y^(3/2)
The result: 3x^2y^(3/2)
