For question 1, it is important to know the vertical angles are angles that are equal to each other because they are congruent and are "across" from each other when two lines intersect. Therefore, you can set an equation where one side is equal to the other as you are solving for x, which would be 2x=x+30. You may then solve this equation like any other equation based on mathematical properties and operations, whereas this is how you may do question #1.

Answer:

Option B.

Step-by-step explanation:

The given table of values is

x f(x)

-3 -2

-2 0

-1 2

0 2

1 0

2 -8

3 -10

4 -20

We need to find the interval for which the function f(x) is positive.

From the given table it is clear that the value of function f(x) is negative before -2 and after 1.

The function positive between x=-2 and x=1. So, we can conclude that the function f(x) is positive for the interval (-2,1).

Therefore, he correct option is B.

if polygon MAST with coordinates M(-3,-1), A(-3,2),S (-1,3) and t (1,1) is reflected across x=-3, then which of the following co

Nookie1986 [14]

Let 'a' be the point and 'A' be the reflection of point 'a' through line x= -3

we know, (a+A)/2 (mid point of line aA) should lie on line x= -3

so by using this, we calculate vertices of reflected shape of MAST, we get

(-3,-1), (-3,2),(-5,3) and (-7,1)

Answer:

The situation you are describing can be written as y=2x, or in this case t=2f, for every fragrance purchased there are 2 ounces of lotion that are given. Since the ounces of fragrance are not shown in this question, we can only make the graph on the ounces of lotion for every fragarance purchased. The points of the graph represent that for every fragrance bought, there is twice the amount of that in ounces of lotion. In summary, the rule is t=2f where t would equal purchases of fragrance and f would equal the ounces of lotion.

(If there is any more you would like to add to the question I can answer that.)

The height of an equilateral triangle h equals 3√2s where s is the length of a side. Suppose an equilateral triangle is made wit

nirvana33 [79]

Answer:

The correct option is;

B. a. Whole number b. Irrational number

Step-by-step explanation:

The height, h of the equilateral triangle = 3·√2·s

The item by which equilateral triangle is made = 2-inch toothpicks

Therefore, we have;

The sides of the equilateral triangle = Comprises multiples of 2 inches

Therefore, the sides of the equilateral triangle is a whole number

The height of the triangle is the product of the side and (√3)/2

Therefore, the height of the triangle is an irrational number

The correct option is A. a. Whole number b. Irrational number.

A whole number are the positive counting numbers, 0, 1, 2, ..., while an integer includes negative numbers which is not possible for a real triangle.
