Answer:
Step-by-step explanation:
D. the corresponding sides of triangle ABC and triangle A'B'C' are congruent
because the sides do not change their length when we rotate the triangle
That's not a linear system, but you have an awesome school system for giving you this problem.

Multiply by 6xy to clear the fractions.

That's a second degree equation, also known as a conic. That one happens to be a hyperbola.


Let's clear the fractions from the second equation, multiplying out common denominator xy:


We are being asked to find the meet of two hyperbolas, so we expect two answers, a quadratic equation.
Substituting,





We have to rule out x=0 because it's in the denominator.


Answer: (44/19, 33/20)
Answer:
$34,000
Step-by-step explanation:
First they had 30,000
Then wrote off 40,000
So balance is 30,000 - 40,000 = -10,000
Now, they want 8% of 300,000 as uncollectible. So that would be
0.08 * 300,000 = 24,000
Thus, to bring the balance to 24,000 [balance is -10,000], how much would they need to add?? Let it be x:
-10,000 + x = 24,000
x = 24,000 + 10,000 = $34,000

Step-by-step explanation:
<u>Angles in a Circle</u>
An exterior angle of a circle is an angle whose vertex is outside a circle and the sides of the angle are secants or tangents of the circle.
Segments AE and DE are secants of the given circle. They form an exterior angle called AED.
The measure of an exterior angle is equal to half the difference of the measure of their intercepted arcs.
Intercepted arcs in the given circle are AD=113° and BC=48°. The exterior angle is:
