Answer:
D: all real numbers
R: (5, ∞)
Step-by-step explanation:
D: you can plug in anything for x and it makes sense. You can raise 3 to any real power (2, 1/2, -10 etc) and get an answer.
R: Because 3^x only produces positive numbers, the range is (0+5, ∞) ---> (5, ∞).
Velocity is speed. It doesn't matter what direction.
First step is to subtract 4
Answer:
x=4/9
Step-by-step explanation:
We first let 0.4 (4 being repeated) be x.
10x=4.4
10x-x=4.4-0.4
9x=4
x=4/9
Answer:
False
Step-by-step explanation:
Slope intercept form is y=mx+b where x is our slope and b is our y value. Thefore, 3 is our y value not 4.
