2.
2x/5 = (x+3)/3
2x*3 = 5(x+3)
6x = 5x + 15
6x-5x =15
x = 15

3. (5x-4)/(4x+7) = 13/11
11(5x-4) = 13(4x+7)
55x - 44 = 52x + 91
55x-52x= 91 + 44
3x = 135
x=45

alan deposited 2500 in an investment account that pays an interest rate of 7.8% compounded monthly if he makes no other deposirs
xeze [42]
Use Compound Interest Monthly Formula:
A = P(1 + r/n)^nt
A = Future Amount
P = Initial Amount
r = Interest rate
n = monthly
= 12 months
t = 15

In this case:
P = 2500
r = 7.8%
n = 12 months
t = 15 years

7.8% = 7.8/100
= 0.078

2500(1 + 0.078/12)^12(15)
= 8024.54 —> Final Answer.

Answer:

Full proof below

Step-by-step explanation:

\displaystyle ax^2+bx+c=0\\\\ax^2+bx=-c\\\\x^2+\biggr(\frac{b}{a}\biggr)x=-\frac{c}{a}\\\\x^2+\biggr(\frac{b}{a}\biggr)x+\biggr(\frac{b}{2a}\biggr)^2=-\frac{c}{a}+\biggr(\frac{b}{2a}\biggr)^2\\\\x^2+\biggr(\frac{b}{a}\biggr)x+\frac{b^2}{4a^2}=-\frac{c}{a}+\frac{b^2}{4a^2}\\ \\\biggr(x+\frac{b}{2a}\biggr)^2=-\frac{4ac}{4a^2}+\frac{b^2}{4a^2}\\ \\\biggr(x+\frac{b}{2a}\biggr)^2=\frac{b^2-4ac}{4a^2}\\ \\x+\frac{b}{2a}=\pm\frac{\sqrt{b^2-4ac}}{2a}\\ \\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}
