Joel wants to determine the solution to 0.5^x+4 ≤ 2. He first graphs 0.5^x+4-2 ≤ y as shown. Joel then graphs y ≤ 2 on the same coordinate plane and claims that the solution set to 0.5^x+4 ≤ 2 is the interval [6, infinity), because the overlapping region matches this interval. which statement describes Joel's error?

the answer is A

Step-by-step explanation:

Just took the test

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
