What you can use for this case is a function of the potential type.
We have then
y = a (b) ^ x
Where we have:
Walker starts the fund by depositing $ 5
a = 5
Each week the balance of the fund is twice the balance of the previous week:
b = 2
The function is:
y = 5 (2) ^ x
The number of weeks to reach $ 1280 is 8 weeks.
Check:
y = 5 (2) ^ 8
y = 1280
Answer:
An equation can be used to find the number of weeks, x, after which the balance of the fund will reach $ 1,280 is:
y = 5 (2) ^ x
The number of weeks that it takes to reach the class goal is
8 weeks
Answer:
A.GFD=EFF
is not a pair of congruent angles in the diagram below
3x + y = 9
3x - 5y = 15
15x + 5y = 45
<span>3x - 5y = 15
</span>
18x = 60
x = 10/3 or 3.33.
Plug that into the equation and Y is equal to -1. Hope this helped. Once again the answer is (10/3, -1).

Answer:
Step-by-step explanation:
<h3>Solution 1</h3>
The both triangles are marked as isosceles.
The bottom triangle
<u>Missing angles are same:</u>
- 1/2(180 - x - 85) = 1/2(95 - x)
The top triangle
The equal angles measure 38° as one of them is vertically opposite to 38° angle.
On the other hand same angle is complementary with the one we found above (together forming a right angle).
<u>So we have:</u>
- 1/2(95 - x) + 38 = 90
- 1/2(95 - x) = 52
- 95 - x = 104
- x = 95 - 104
- x = - 9
<h3>Solution 2</h3>
The angle 2 is the exterior angle of the top triangle.
The non-adjacent interior angles are equal to each other and same as vertical angle of the top vertex, 38°.
<u>Also we have:</u>
<u>Compare and solve for x:</u>
- x + 85 = 76
- x = 76 - 85
- x = -9
