I need to know the answer
almond37 [142]

Answer:

A

Step-by-step explanation:

That's the formula for the solution of a quadratic equation, like this:

a {x}^{2}  + bx   +  c = 0

The formula is:

x =  \frac{ - b± \sqrt{ {b}^{2} \:  - 4ac } }{2a}

In your case:

a = 7 \\ b =  - 5 \\ c =  - 2

The only answer that has c = -2 is the first one, A.

If you move the 5 to the left-hand side, it becomes -5 and with the +3 gives a -2.

larisa86 [58]

Answer:

Compound interest

$34633.25

Step-by-step explanation:

Everything starts of at 100% and the rate of interest is 9.5% so we add them on=109.5%

Now we want this percentage as a decimal so we divide by 100 = 1.095 this our multiplier

Then get the original amount that you borrowed = 6000 times by the multipler=1.095 to the power of number of years so

6000 multipled by 1.095 to the power of 5

Giving me $34633.25
