Answer:
c

Answer:
see attached
Step-by-step explanation:
You want to multiply each individual value in the matrix by the same scalar value. That is represented as the product of a constant and the matrix.
___
The tax amount on price P is 0.07P. When that is added to P so you have the price + tax, you get P + .07P = 1.07P.
In this case, P is a matrix of prices.
Answer:
2x + y -6 = 0
Step-by-step explanation:
The general form is 
. It requires that A and B be greater than 1 (not fractions or decimals) and A is positive. This equation is 2x + y = 6 is almost already in the form. Subtract C to both sides to make it general form. 2x + y - 6 =0. The coefficients of the x and y are greater than 1 and 2 is positive. This meets the requirements.
m=-(5/4)
From left to right, (1,3) is first and then comes (5,-2). Always remember when finding slopes without equations, the rule is RISE over RUN, to the numerator and denominator, respectively.
The y value of the second coordinates becomes negative which is unlike the y value in the first coordinates, which means our slope is downward, meaning it has a negative sign in front.
In every slope, there’s a numerator, being the rise, and a denominator, being the run.
To find the rise, we must look at the y values. Starting at 3 going to -2 has a space of 5 units, making that our numerator.
To find the run, the first x value is 1 and the second is 5, making a space of 4, which is out denominator.
With these two numbers and the negative sign, we get -(5/4) as our slope.
