f(x) = (3/4)ˣ - 4
As x gets really negative (3/4)ˣ grows positively without bound (because it's (4/3)⁻ˣ and 4/3 > 1).
As x gets really positive (3/4)ˣ tends to zero but never quite gets there.
So (3/4)ˣ > 0 for all x
So f(x) > 0 - 4 for all x
Answer: { y | y > -4 }, first choice
8x+6 <54
subtract 6 from each side
8x < 48
divide by 8
x<6
Choice A
I'm not very good with word problems but if I am correct it is 660 minutes so about 11 hours?
Answer:
ED = 6√3 cm
Step-by-step explanation:
This is a 30-60-90 triangle. Remember the rules. Hypotenuse is always 2x. Leg across from 60° is x√3. Leg across from 30° is x.
12 = 2x
x = 6
ED = x√3
ED = 6√3
