The solution to the matrix equation is x = 2.6
<h3>What is the solution?</h3>
Following the matrix as given, all the elements in the right hand side would have to be multiplied by X hence we have;
-x 4x -8 17
6x 3x = 21 -21
Taking the determinant of both matrices;
-3x^2 - 24x^2 = 168 - 357
-27x^2 = -189
x^2 = -189/-27
x = 2.6

Answer:
Linear
Step-by-step explanation:
y = 2x + 4 is linear -- any equation involving only first powers of x and y (and constants) is linear. You'll usually see linear equations in the forms y = mx + b, ax + by = c, or y - y1 = m(x - x1).
If you take any two points, find the slope of the line between them, and then plug in one point to solve for the constant term (like you did), you will get a linear equation through those points.
Answer: the answer is 3/10
Step-by-step explanation: because its 3/10
I assume it is 100 meters, not 100100 meters.
Length (L)=width(w)+4
Perimeter: 2L+2W>100
Plug L=W+4 into the equation 2L+2W>100:
2(W+4)+2W>100
2W+8+2W>100
4W+8>100
4W>92
W>23
the width needs to be at least 23 meters
Answer: 45.5 miles
Step-by-step explanation: divide182 by 4
