-4 is the slope in the equation
5 lbs of apples x pounds of apples---------------------- = ----------------------------2 cups of sugar 4/3 cup of sugar Solve for x.
1 + sec^2(x)sin^2(x) = sec^2(x)
This becomes
1+tan^2(x) = sec^2(x) which is an identity
You could
1 + sin^2(x)/cos^2(x) = sec^2(x)
then
cos^2(x) + sin^2(x) = cos^2(x)sec^2(x)
1 = 1
0.86= 86/100 this is because the 6 is in the hundredths place so the denominator is going to be 100<span />
1. Original equation
2.Distributive property
