Answer:
x = -2
Step-by-step explanation:
x = -2, is a vertical line, y = 5 is a horizontal line.
Answer:
See below.
Step-by-step explanation:
There is an infinite number of lines parallel to y = -3/2x - 1.
They have the same slope, -3/2, and a different y-intercept.
Examples:
y = -3/2x + 1
y = -3/2x
y = -3/2x - 5
First of all, i will start by comparing the given values. That will be;
7/2 meters=$231/4
1 meter= x
I represented the unknown value by x. Anyway, you have to cross and multiply. SO 7/2 multiplies x to give you 7/2x and 1 multiplies 231/4 to give you 231/4. That will be;
7/2x=231/4
Divide the both sides by 7/2.
7/2x÷7/2=231/4÷7/2
When dividing fractions, the division sign changes to a multiplication sign and the fraction on the right turns upside down. So;
x=231/4 x 2/7
x=231/14
x=$33/2.
Hope i helped.
Answer:
The rank of the matrix is 3.
Step-by-step explanation:
Consider the prided information.
Reduce the matrix in row echelon form as shown:
The rank of a matrix is the number of non zeros rows.
Thus, the rank of the matrix is 3.
