Answer:
x= -2 y=0
Step-by-step explanation:
Answer: Y = 7x/2 -2
Step-by-step explanation:
Y intercept of -2 means there's a point at (0,-2).
Given the two points (4,12) and (0,-2), we can now find the slope
12-(-2)/4-0 = 14/4 = 7/2 which is the slope
so the equation is Y = 7x/2 -2
Answer:
x = 8 is the answer
Step-by-step explanation:
In order to find the solution of Equations using Cramer's rule
we shall find matrices
D=
=
![D_{1} = \left[\begin{array}{ccc}4&-3\\-16&-2\end{array}\right]](https://tex.z-dn.net/?f=D_%7B1%7D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%26-3%5C%5C-16%26-2%5Cend%7Barray%7D%5Cright%5D)
l D l = Determinant formed by coefficient of variables
Here l D l = 5X(-2) - 1X(-3)= -10+3 = -7
l D1 l = Determinant formed by replacing first column In D by numbers on the right side of the equations
Here l D1 l = 4X(-2)- (-16)X(-3)= -8-48 = -56
here x is given by 
x = 
x = 8
The answer is 380. You divide 1520 by 4 and that gives you the answer.
