Answer:
Step-by-step explanation:
For two matrix P and Q, the product, say PQ is defined when:
The number of columns of P = The number of rows of Q
Since A is a 2×2 matrix and B is also a 2×2 matrix
Thus both AB and BA are possible.
So AB is:
BA is:
Answer:
a) 3x + y = 5
Step-by-step explanation:
Insert the coordinates into the Point-Slope Formula FIRST, <em>y</em><em> </em><em>-</em><em> </em><em>y</em><em>₁</em><em> </em><em>=</em><em> </em><em>m</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em>₁</em><em>)</em><em>,</em><em> </em>with their CORRECT signs. Remember, in the Point-Slope Formula, all the negative symbols give the OPPOSITE term of what they really are. So, with that being stated, here is how you will set it up: <em>y + 1 = -3(x - 2).</em> After this [Distributive Property], convert to Slope-Intercept Form by moving "-1" to the right side of the equivalence symbol, resulting in <em>y</em><em> </em><em>=</em><em> </em><em>-</em><em>3x</em><em> </em><em>+</em><em> </em><em>5</em><em>.</em><em> </em>Go to your answer choices and see if this is there. No. So then, we try going from Slope-Intercept to Standard by moving "3x" to the left side of the equivalence symbol to end up with <em>3x + y = </em><em>5.</em><em> </em>This answer choice is found, there you are finished.
Answer:
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
