Well since we can use a base of 1 we know that 1 - 45 is less than 4 but -1 + 45 is not, which follows the assumption that x>0, but now we need to know what x is less than to fit the inequality. If we use 5 as a trial we can see that 5 - 9 = -4 so 0<x<5 is your answer. Hope this helps I basically used trial and error. If you want to check try 3 or 4 for x and it will work but 6 will not.
Answer:
The answer is c!
Step-by-step explanation:
The denominator is in the bottom of a fraction bar while the numerator is on the top.
Answer:
Neither parallel nor perpendicular
Step-by-step explanation:
To tell whether two lines are parallel or perpendicular, look at their slopes.
Parallel lines will have the same slope. This isn't the case since the first line has a slope of 1 and the second has a slope of -1.
Perpendicular line have slopes that are negative inverses of the other. This also isn't the case for these two lines. Although the slopes have opposite signs, the numbers aren't inverses.
The two lines are neither parallel nor perpendicular.
Independent. A dependent variable would be a letter or symbol that needs a letter or key to be solved.
