a exponent 2-b exponent 2
ab
Ur not dumb!!! i graphed the line for u here. i suggest watching some khan academy videos for extra practice!
ANSWER : $1,215.51
P= Principal = $1000
R= rate = 5% = 0.05
N= number or periods in 1 year (1 time pre year)
T= time expressed in years = 4 years
A= P (1 + r/n) nxt
= 1,000 (1+ 0.05/1) 1x4
= 1,215.51
Given your ordered pair you would assume a = 5, b = 2
Set up both equations
5 + 2 = 7
7 = 7 (the numbers are equal so this correct)
2(5) - 8 = 2
10 - 8 = 2
2 = 2 (the numbers are equal so this is also correct)
Because both equations work with the ordered pair they <em>are</em><span> the solution of the given system.</span>
9x^2 - 8x - 1 = 0
(9x + 1(x - 1) = 0
x = -1/9 , 1
x intercepts are -1/9 and 1.
