Answer:

A vertical line has an infinite or undefined slope since the denominator is zero.

Step-by-step explanation:

Parallel lines by definition refers to lines that never intersect or meet since they have identical slopes. The slope of line is defined as;

(change in y)/(change in x)

For a vertical line, the y values are changing while the x values remain constant. The slope of this line will thus have a zero value in the denominator implying that its slope will not defined or will be infinity.

Look at the function f(x) = x3 - 4 x. which describes an interval in which the function is increasing?

Bad White [126]

Differentiate it
get f ' (x)=3x^2-4
put 3x^2-4=0
x=2/√3,-2/√3
so interval
x∈(-2/√3,2/√3)

Marvin earns $8.25 per hour at a summer job. He wants to buy a video game system that cost $206.25 write an equation to model th

Olin [163]

Amount Earned (E) = 8.25*Hours (H)

Since he wants to buy a game system you can also write this as an inequality, if the amount of the game system has any relevance in the problem.
8.25*H >= 206.25
