Answer:
(a) 5/6
Step-by-step explanation:
Positive numbers are greater than negative ones.
Fractions with the same denominator are greater if their numerator is greater.
All of these fractions have the same denominator. Because 5 > 1 > -1 > -5, the ordering of the fractions is ...
5/6 > 1/6 > -1/6 > -5/6
The fraction with the greatest value is 5/6.
Answer: b) increasing for x < -4/3 and x > 4/3
decreasing for -4/3 < x < 4/3
<u>Step-by-step explanation:</u>
Graph the equation and the follow the curve from left to right. When you are going up, it is increasing. When you are going down, it is decreasing.
see the image below. Red is increasing. Blue is decreasing.
The vertices occur when x = -4/3 and x = 4/3
Answer:
5x + 3
Step-by-step explanation:
We factor 25x^2 + 3x + 9.
25x^2 is a perfect square; 25x^2 = (5x)^2
9 is a perfect square; 9 = 3^2
This expression may be a perfect square trinomial.
25x^2 + 30x + 9 = (5x + 3)^2
We check the middle term: 2ab = 2 * 5 * 3 = 30
The coefficient, 30, is correct, so we are dealing with a perfect square trinomial.
length = 5x + 3
