The element on the position (1,1) in the product matrix FC is a scalar product of the first row in F and the first column in C.

Therefore the element in the position (1,1) in FC will be a scalar product of (-2,0) and (12,1):

$-2\cdot 12+0\cdot 1 = -24+0=-24$

The only matrix that has a value of -24 in the position (1,1) is matrix B.

Therefore, the answer is matrix B.

Find the slope and y-intercept of -x + 2y = 3. I need help on working this problem out

natita [175]

Answer:

So the slope of this function is $\frac{1}{2}$ and the y-intercept is $\frac{3}{2}$

Step-by-step explanation:

A first order function has the following format:

$y = ax + b$

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.

We have the following equation:

$-x + 2y = 3$

We just have to rewrite this equation

$2y = x + 3$

$y = \frac{x+3}{2}$

$y = \frac{x}{2} + \frac{3}{2}$

Which means that

$a = \frac{1}{2}, b = \frac{3}{2}$

So the slope of this function is $\frac{1}{2}$ and the y-intercept is $\frac{3}{2}$
