<h3>
Answer: C) 5/2</h3>
==========================================================
Explanation:
The term "zero" is the same as "root".
The root of f(x) is found by replacing f(x) with 0 and solving for x.
f(x) = 4x-20
0 = 4x-20
0+20 = 4x
20 = 4x
4x = 20
x = 20/4
x = 5
The root of f(x) is 5. If you plugged in x = 5, then you'll land on f(5) = 0.
Your teacher then wants to know what value of k will have g(x) get the same root of 5. In other words, we need to find k that will allow g(5) = 0.
We'll replace g(x) with 0 and plug in x = 5. Solving for k leads to...
g(x) = -0.5x+k
0 = -0.5*5+k
0 = -2.5+k
0+2.5 = k
2.5 = k
k = 2.5
k = 5/2

Answer:
−9⋅(5j+k) = -45j -9k.
Step-by-step explanation:
Given : −9⋅(5j+k)
To find : distributive property.
Solution : −9⋅(5j+k)
By distributive property a( b +c ) = a*b + a*c.
Then −9⋅(5j+k) = -9 *5j + (-9 *k)
−9⋅(5j+k) = -45j -9k.
Therefore, −9⋅(5j+k) = -45j -9k.
