Answer:
A
Step-by-step explanation:
the leading degree(the biggest power in the function) x^4 and the leading coefficient is the number next to the highest power which is -5
so the answer should be
-5,4,x -> infinity, f(x) -> -infinity ; x -> -infinity, f(x) -> -infinity
when you get asked questions like this look for the biggest power and the number next to it. if the power is even x will always be positive if its odd x can be either positive or negative it depends on restrictions.
for instance in this example -5 * x^4 will always give you negative because -5 will multiply with a positive number x (the power is even so its always positive)
Your answer is A.
The charge for a 1-mile ride is going to be the initial $2 plus the $0.20 for one mile. $2 + $0.20 = $2.20
The charge for a 2.7 mile ride will be equal to the initial $2 plus the equivalent of two and seven tenths of a mile.
$2 + $0.20 x 2.7 = 2.54
Answer:
Step-by-step explanation: Volume is the amount of space something takes up, just add up the numbers once you found them.
-7(4-2)+1=15-7x
-7 x 2 + 1 = 15 - 7x
-14 + 1 = 15 -7x
-13 -15= -7x
-28 = -7x
-28 / -7 = x
x=4
3x - 54 = 160 >I just flipped the equation
3x - 54 (+54) = 160 (+54) added 54 each
3x = 160
3x/3 = 160/3 >divided 3 to each side
x = 160/30
