except of A. the others are correct
Step-by-step explanation:
that is what i know. i guess
If you would like to find the solution to the system of equations, you can do this using the following steps:
2x = 5y + 4 ... 2x - 5y = 4 /*(-3)
3x - 2y = -16 /*2
_____________
-6x + 15y = -12
6x - 4y = -32
_____________
-6x + 15y + 6x - 4y = -12 - 32
11y = -44 /11
y = - 44/11
y = -4
<span>2x = 5y + 4
</span>2x = 5 * (-4) + 4 = -20 + 4 = -16
2x = -16
x = -16/2
x = -8
(x, y) = (-8, -4)
The correct result would be (<span>-8, -4</span>).
Answer: z-1 (6) = 0
Step-by-step explanation:
I suppose that the notation:
(z-1)(x) refers to the inverse function of z(x).
Now, by definition, we know that:
if z(x) = y
then z-1(y) = x.
Now we want to find the value of z-1(6)
This value will be equal to the input that we need have:
z(x) = 6.
By looking at the graph, we can see that the value of the function is 6 when x = 0.
then:
z (0) = 6
This implies that:
z-1 (6) = 0
