-------------------------------------------------------
Equation Given :
-------------------------------------------------------
16x² = 121
-------------------------------------------------------
Take away 121 from both sides:
-------------------------------------------------------
16x² - 121 = 0
-------------------------------------------------------
Make each term a perfect square
--------------------------------------------------------
(4x)² - (11)² = 0
--------------------------------------------------------
Apply algebraic rule : a² - b² = (a + b)(a - b)
--------------------------------------------------------
(4x + 11) (4x - 11) = 0
-------------------------------------------------------
Apply zero product property :
-------------------------------------------------------
4x + 11 = 0 or 4x - 11 = 0
--------------------------------------------------------
Solve for x :
--------------------------------------------------------
4x = - 11 or 4x = 11
x = -11/4 or x =11/4
--------------------------------------------------------------------------
Answer: x = -11/4 or x = 11/4
--------------------------------------------------------------------------
Answer: C) $1951.53
<u>Step-by-step explanation:</u>
- A is amount accrued (final balance)
- P is the Principal (original amount deposited)
- r is the rate (in decimal form)
- t is the number of years
A=1500(1+0.068)⁴
= 1500(1.068)⁴
= 1951.53
It's 7,000 because 1,000*7 = 7000
4/5x The number attached to to “x” is going to be the slope
