<em>HAVE A NICE DAY</em><em>!</em>
<em>THANKS FOR GIVING ME THE OPPORTUNITY</em><em> </em><em>TO ANSWER YOUR QUESTION</em><em>. </em>
A=3,500×(1+0.03÷2)^(2×20)
A=6,349.06
Find and review the slope formula.
The slope of a line segment that connects the points (a, b) and (c, d) is
d-b
m = --------------
c-a
Write out this formula for a=-3, b=-4, c=6 and d=-1.
Divide both sides by 2 to get x>3
