Answer:
Correct choce is (a). 30.
Step-by-step explanation:
Given equation is
.
Now we need to find the value of (fof)(3). Then select correct matching choice from the given choices. Where given choices are:
(a). 30
(a). 33
(a). 6
(a). -6
Now let's find 







Hence correct choce is (a). 30.
Line <span>–3x + 9y = 18
</span>
x-intercept when y = 0
so -3x = 18
x = -6
y-intercept when x = 0
so 9y = 18
y = 2
answer
x-intercept (-6,0)
y-intercept (0, 2)
hope it helps
<h2>
Answer:</h2><h3>False</h3>
<h2>
Step-by-step explanation:</h2>
In this problem, we have the following System of Three Equations in Three Variables, so our goal is to determine whether
is the solution to this system, that is, the ordered triple
where three planes intersect.
The easier way to find the answer is to plug in the x, y and z values in the equations and figure out whether the equations satisfy the solutions. Then:

STOP HERE! Since the x, y an z values doesn't satisfy the second equation, the
is not the solution to the system of equations.
Answer:
1. y=-2x+5
2. y=1/2x-7.5
Step-by-step explanation:
you plug in the cordinates for the y intercept and you already have the slope.
y=mx+b
m= slope which is -2
Answer:
x^3-4x^2+25x-100
Step-by-step explanation:
We have 2 roots -5i and 4. Using the conjugate root theorem for the root -5i, we know that 5i should be another root
Combining the roots into a polynomial gives us:
(x+5i)(x-5i)(x-4)
Expand:
(x^2 + 25)(x-4)
x^3-4x^2+25x-100
