You want to start by finding the per hour speed.
125 miles / 3 hours ≈ 41.6666666… miles each hour
If you drive that speed for 5 hours: 5 hours * 41.6666… mph ≈ 208.333… miles
Answer:
i think IV.
Step-by-step explanation:
The function f(x) is defined in to different ways depending on the value of X. When x is < 5, use the expression 2x - 1 to evaluate the function When x is ≥ 5, use the expression x2 - 3 for example f(1) = 2(1) - 1 = 1 f(10) = (10)2 - 3 = 97
The equation 0 = -2x2 5x - 3 was the quadratic formula that Zacharias used. However, he started substituting as:
Quadratic formula as x = ; substitution as x
The errors he made: he mistakenly used the negative (-) and postive (+)
* -5 should have been 5
* 52 should have been -52
* both the numerator and the denominator should have been -2 instead of 2
