-24x + 24y is the answer simplified hope this helps
Answer:
Option A.
Step-by-step explanation:
The given matrix is
We need to find the system of equations which is represented by the matrix.
In the given matrix first row represents the first equation and second row represents the second equation of the system of equations.
Let two variables are x and y.
First column represents the coefficients of x and second column represents the coefficients of y.
Numbers on the right side of the matrix represents the numbers which are right side of the equations.
Now, the required equations are
Therefore, the correct option is A.
Answer:
D
Step-by-step explanation:
They are clearly not the same line since they don't have the same slope. Because they don't have the same slope, they're not parallel either. In order to be perpendicular, the product of the slopes of both lines must be -1. Since 3/4 * 4/3 ≠ -1, they are not perpendicular, leaving us with option D as the answer.
Answer:
6) y = -7x +11
8) y = -1/3x -1
10) y = 5/4x -2
Step-by-step explanation:
It is convenient to start with a point-slope form of the equation.
y = m(x -h) +k . . . . . line with slope m through point (h, k)
__
6) m = -7, (h, k) = (2, -3)
y = -7(x -2) -3 = -7x +14 -3
y = -7x +11
__
8) m = -1/3, (h, k) = (-3, 0)
y = (-1/3)(x -(-3)) +0
y = -1/3x -1
__
10) m = 5/4, (h, k) = (4, 3)
y = 5/4(x -4) +3 = 5/4x -5 +3
y = 5/4x -2
