Answer:
(-2, 5/3)
Step-by-step explanation:
Step 1: Write out systems of equations
y = 2/3x + 3
x = -2
Step 2: Substitution
y = 2/3(-2) + 3
y = -4/3 + 3
y = 5/3
Step 3: Write solution
(-2, 5/3)
The correct statements about similarity of triangles are A, B, and C.
<h3>
What is a similar triangle?</h3>
Similar triangles are triangles that have the same shape, but their sizes may vary. This type of triangles are said to have congruent angles and corresponding sides.
From the given figure,
- triangle ABC is a right triangle and triangle BDC is also a right triangle
- triangle ABC is a right triangle and triangle ADB is also a right triangle
- angle ABD is 45 and angle BCD is also 45 degrees.
Thus, the correct statements about similarity of triangles are A, B, and C.

Answer:
<em>After </em><em>47</em><em> days she will have more than 90 trillion pennies.</em>
Step-by-step explanation:
At the beginning there was 1 penny. At the second day the amount of pennies under the pillow became 2.
The amount of pennies doubled each day. So the series is,
This series is in geometric progression.
As the pennies from each of the previous days are not being stored away until more pennies magically appear so the sum of series will be,
where,
a = initial term = 1,
r = common ratio = 2,
As we have find the number of days that would elapse before she has a total of more than 90 trillion, so
The Greatest common factor of both should be 5.
Step-by-step explanation:
Im not sure ut it looks like 3x over 3x would cancel eachother out.
