Question:
Find the constant of proportionality k. Then write an equation for the relationship between x and y
Answer:
(a) 
(b) 
Step-by-step explanation:
Given
Solving (a): The constant of proportionality:
Pick any two corresponding x and y values
The constant of proportionality k is:
Solving (b): The equation
In (a), we have:
k can also be expressed as:
Substitute values for x1, y1 and k
Cross multiply:
Open bracket
Add 10 to both sides
Answer:
D = $8637.45
Step-by-step explanation:
Rate = 3.65% = 0.0365
Principal = 5000
Time (t) = 15 years
N = 12 (since its compounded monthly)
Compound interest (A) = P(1 + r/n)^nt
A = 5000(1 + 0.0365 / 12)^15*12
A = 5000(1 + 0.00304)¹⁸⁰
A = 5000(1.00304)¹⁸⁰
A = 5000 * 1.7269
A = 8634.86
The investment would worth $8634.86
Note: the final answer may vary slightly from the answer in the options due to ± from approximation
(-7,1) is a solution to the inequality y<0.5x+9
Answer:
b is the answer I believe so because it have to be greater than 0

Answer:
6a + 1
Step-by-step explanation:
First, you need to multiply everything in the brackets by 3L
(7 + 2a) x 3 =
7 * 3 = 21
2a * 3 = 6a
21 + 6a
Now you can subtract the 20 from this:
6a + 21 - 20
Simplified down:
6a + 1
