For this case we must factor the following expression:
We rewrite the middle term as a sum of two terms whose product is
And whose sum is
These numbers are:
-5 and -3
So:
We factor the maximum common denominator of each group:
We take common factor
Answer:
Answer:
43.
44.
45. 8
Step-by-step explanation:
43. 0.45% = .0045
44. •
=
45. VIII = 8
Multiply both the numerator and denominator by , which is called the "conjugate" of
:
Why do we pick this number? Recall the difference of squares factorization:
Now replace and
. Then
So in your fraction, you end up with
Finally, just expand the product.
Answer: <em>y = 3x + 2</em>
Step-by-step explanation:
<em>Let's choose two arbitrary points on the graph.</em>
<em>For example, let these be points with coordinates (1, 5) and (2, 8).</em>
<em>Substitute the coordinates of these points into the above formula and derive the equation of a straight line.</em>
