Answer:
(k - 4) ÷ 9
(k - 4) / 9
Step-by-step explanation:
k decreased by 4 = k - 4
quotient of k decreased by 4 and 9
= (k - 4) ÷ 9 (using division sign)
Or
= (k - 4) / 9 (as a fraction)
Answer:
B and D
Step-by-step explanation:
a is right because there are numbers that exist that are larger than five and smaller than 9
c is right because again, there are numbers that exist that are larger than -3 and smaller than 7.
b cannot be right because there are no numbers that can be larger than 9 that are also smaller than 5
d also cannot be right because there are no numbers that are less than -5 that are also more than -3.
Answer:
2x² + 4x + 3
Step-by-step explanation:
Given:
f (x) = 2x +1
g(x) = x² + 2x + 1
to find f(g(x)), simply take the x-terms in f(x) = 2x+1 and replace them with g(x) = x² + 2x + 1
Hence,
f(g(x))
= f(x² + 2x + 1)
= 2(x² + 2x + 1) + 1
= 2x² + 4x + 2 +1
= 2x² + 4x + 3
Answer: each of the students took 1/4 of an eraser home.
Step-by-step explanation:
On the last period our teacher had 1/2 of an eraser left. She gave it equally to 2 students. This means that the amount of eraser that each student takes home would be
(1/2)/2 = 1/2 × 1/2 = 1/4 of an eraser. Converting to decimal, it becomes 0.25 of an eraser.
