Answer:
D. 10
Step-by-step explanation:
Given f(x)=3x-8
f(6)=3(6)-8
f(6)=18-8
f(6)=10
Answer:
12.5
Step-by-step explanation:
square root of 10^2 - 8^2 = 6 gives us missing side
sin^-1(8/10) = 53.13 gives us half of the angle
90-53.13 = 36.869 gives us the angle of the triangle on the right
tan(36.869) x 6 = 4.5
4.5 + 8 = 12.5
Hope that helps,
Good Luck! x
Answer:

Step-by-step explanation:
So we have the inequality:

Add 1 to both sides. The left side cancels:

Subtract 4x from both sides. The right side cancels:

Divide both sides by -1. Since we're dividing by a negative, we flip the sign:

And we're done!
Our solution is all numbers less than -8.
