Answer:

Step-by-step explanation:
The magnitude of 3D vector
can be given by the following:

Plugging in given values, we have:
.
Substitution
y = 2x - 12
y = -x + 3
-x + 3 = 2x - 12
+ x + x
-----------------------------
3 = 3x - 12
+ 12 + 12
-----------------------
15 = 3x
------ ------
3 3
x = 5
y = 2(5) - 12
y = 10 - 12
y = -2
The final answer is (5,-2).
16.92 × 8.4 = 142.128
This is called the product
