Mark makes a pattern that starts with 5 and uses the rule “subtract 1, and then multiply by 3.” Which expression can be used to find the third number in Mark’s pattern? A. 5−1⋅3−1⋅3

B. 3(5−1)+3(5−1)

C. 3[3(5)−1]

D. 3[3(5−1)−1]

Choose one correct answer.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
