0.08x+0.075 (6000-x)=472.5
Solve for x
0.08x+450-0.075x=472.5
0.08x-0.075x=472.5-450
0.005x=22.5
X=22.5/0.005
X=4500 invested at 8%
Answer:
<h2>x = 7</h2>
Step-by-step explanation:
<u>Multiply the terms in the bracket</u>
We have
- 3x - 14 - 5x = - 70
- 8x - 14 = - 70
Using the addition property, add 14 to both sides
That's
- 8x + 14 - 14 = - 70 + 14
- 8x = - 56
<u>Divide both sides by - 8</u>
That's

</h3>
We have the final answer as
<h3>x = 7</h3>

Answer:
(-1, -0.5)
Step-by-step explanation:
It is between -1 and 0 and it is on -1
X = -3/2 and is first degree
Part A
Chorus:
Expontential growth = b*a^x
b = 15
a = 1.12 (a= r+1), r = 12%
Which gives a function of f(x) = 15*1.12^x
Band
Linear growth = ax+b
a = 2
b = 30
Which gives a function of g(x)=2x+30
Part B:
f(9) = 15*1.12^9 = 41.59
g(9) = 2*9+30 = 48
Part C:
This is probably problem solving, where you're allowed to use calculators and other softwares.
Therefore you can use different softwares, and make f(x) = g(x).
