Answer:
in 2005, 17.3 percent of students are taking at least one online course
Step-by-step explanation:
f(5) = 2.6(5) +4.3 = 17.3
The definition of the function f(x) tells you that f(5) = 17.3 means 5 years after the year 2000, 17.3 percent of students are taking at least one online course.
X=5, should be right correct me if i’m wrong.
First number = X
second number = x +26 ( exceeds means higher so add 26)
x + x+26 = 58
combine like terms:
2x + 26 = 58
subtract 26 from each side:
2x = 58-26
2x = 32
divide both sides by 2:
x = 32/2
x = 16
first number is 16
second number = 16+26 = 42
Answer:
If you add 690 ml of water you will obtain 1.690 liter of 70% alcohol. Of course if you halve the amounts, e.g. 0.5 liter 75% alcohol and 345 ml of water, you will also obtain 45% alcohol solution.
<span>(3x + 5)(x - 3) = 3x</span>² - 9x + 5x - 15 = 3x² - 4x - 15
Answer: 3x² - 4x - 15
