4 0

Answer:

B

Step-by-step explanation:

Rotation 180° is accomplished by negating both the x- and y-coordinates. That is, you multiply each of them by -1. You want the opposite of the identity matrix, so matrix B.

What value of b will cause the system to have an infinite
kvasek [131]

Hi there!

The way that an infinite number of solutions is achieved is when the two equations, when solved together, get an answer which is just a number equal to the same number. To do this, first substitute 6x-b in for y in the second equation.

-3x+\frac{1}{2}(6x-b)=-3

-3x+3x-\frac{1}{2}b=-3

-\frac{1}{2}b=-3

Now, we see that b needs to be equal to -3 when multiplied by -1/2. When both sides are divided by -1/2, b becomes equal to 6. Thus, b must be 6.

Check work:

6x-6=y

-3x+\frac{1}{2}(6x-6)=-3

-3x+3x-3=-3

-3=-3

Thus, as they are equal to each other, the answer is correct. b = 6.

Hope this helps!
