Answer:
The system determinant is 18.
Step-by-step explanation:
Given Equation are:
4x - 2y = 5 (1)
3x + 3y = 7 (2)
The determinant of the two equations, ax - by = X and cx - dy = Y can be written as:
(iii)
<u>In this case,</u>
<u />
a = 4
b = -2
c = 3
d = 3
By putting these value in the equation iii, we get:
=> (4)(3) - (-2)(3)
=> 12 - (-6)
=> 12 + 6
=> 18
Therefore, the system determinant is 18.
Answer:
f(x)=x³-2x²+9x-18
Step-by-step explanation:
complex zeros always occur in pairs.
zeros are 2,3i,-3i
f(x)=(x-2)(x-3i)(x+3i)=(x-2)((x)^2-(3i)^2)
=(x-2)(x^2-9i^2)
=(x-2)(x^2+9)
=x^3-2x^2+9x-18
Answer:
y = (x+2)^2 - 3
Step-by-step explanation:
Because you are shifting the graph down, the y-coordinate is being changed, so you subtract 3 from the original equation. Because you are shifting to the left, you have to add to the x-value. (It's kind of backwards from what you'd think.)
