In the given question, we have a graph given, and on the basis of that graph, we have to find the interval where the graph is increasing, decreasing or constant .

As we see in the graph, that the graph goes up and up only, no where it goes down or it is constant.

So the graph is increasing on all real numbers and decreasing nowhere.

A triangle has a perimeter of 33cm. If the three sides of the triangle are n, 3n−4, and 3n−5, what is the length of each side?
lara [203]

Just did this one.


The perimeter is the sum of the sides.

n + (3n - 4) + (3n - 5) = 33

7n - 9 = 33

7n = 42

n = 6

3n-4=18-4=14

3n-5=13

Check: 6+14+13=33, good

Answer: 6 cm, 14 cm, 13 cm

Eighteen less than three times a number is twice the number. Write and solve
goblinko [34]

Answer:

The number is 18

Step-by-step explanation:

You can write an equation to represent this. Let x represent the unknown number.

3x - 18 = 2x

Move 2x to the left side. Remember, "change the side, change the sign." Add 0 as a placeholder to the right of the equals sign.

3x - 2x - 18 = 0

Simplify like terms.

x - 18 = 0

Move -18 to the right of the equals sign.

x = 18

Now that we know x = 18, we can substitute it into the problem.

"Eighteen less than three times 18 is two times 18."

18 x 3 = 54

54 - 18 = 36

36 is, in fact, two times 18. We can check this by dividing 36 by 2.

36 ÷ 2 = 18
