=2 x+4.8
choice A
Answer:
22x-4
Step-by-step explanation:
2x(3+8)−4
Simplify 3+8 to 11.
2x×11−4
Simplify 2x times 11 to 22x.
22x−4
Answer is choice D. The other choices involve dilations, or scalings, which basically make the graph taller or flatter depending on what the scale factor is. In the case of f(x-1/2)+3, we shift f(x) to the right 1/2 a unit and up 3.
Divide the total by 3 to get the middle value:
294 /3 = 98
Now the 3 numbers are consecutive, so use the numbers on each side of 98:
Smallest = 97
middle = 98
Largest = 99
Step-by-step explanation:
30x = 9(2x+6)
30x = 18x+54
30x-18x = 54
12x = 54
x = 54/12
= 27/6
