NO LINKS OR ANSWERING QUESTIONS YOU DON'T KNOW. Ch. 15 part 1a How can a matrix be used to solve a system of equations. Demonstrate by solving the following system. Show your work. ​

We are given the equations:

x - 3y = 2

3x - 4y = 0

writing the system as matrices

=

which is in the form:

AX = B

solving for X(the matrix holding the variables), we get:

X = (A⁻¹)B

Finding A⁻¹:

now, to do this, we need to find the inverse of A

using this formula to find the inverse of matrix A:

Matrix X:

We know that:

X = A⁻¹B

since matrix X is just a matrix with the variables

x = -8/5

y = -6/5

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

i’m here for points.
