Step-by-step explanation:
1. it is given because the question supplies the fact at the top above the diagram called "Given:"
2. corresponding angle theorem: "when a line intersects 2 parallel lines, then the corresponding angles in the 2 regions of intersection are congruent" (also look at correspond_screenshot, the first image)
3. vertical angle theorem: "when two straight lines intersect, they form two sets of linear pairs with congruent angles" (also look at vertical_screenshot, the second image)
4. transitive: since we now know <2 ~= <1 ~= <3, we can say <2 ~= <3
("If any segments or angles are congruent to the same angle, then they are congruent to each other")

The answers are subtraction, subtraction, and addition property of equality
There are 9 properties of equality, which are addition, subtraction, multiplication, division, distributive, substitution, reflexive, symmetric, and transitive. In this case, we are using the first 2. In algebra, whatever you do to one side has to be done to the other, in the case of the first problem x is being subtracted on both sides, which represents the definition of the subtraction property (If a = b, then a – c = b – c, a is the one side of the equation, b is the other side, and c is the subtraction done on both sides). The first one is the subtraction property of equality, then, and if we look at problem 2, the same thing is done (apart from that it is done with a number, which doesn't affect the property), so it is also the subtraction property.
Now the last problem seems to do the opposite, it seems to be adding instead, in this case, adding 1 on both sides. This follows the definition of the addition property of equality (If a = b, then a + c = b + c) since it is adding c (1) on both sides. So the last problem is the addition property of equality.

16. A snack mix contains toasted oat cereal,
pretzels, and nuts in a ratio of 2:2:1 by
mass. What mass of each ingredient is
needed to make the following amounts of
snack mix?
a) 330 g
b) 210 g
c) 500 g
d) 750 g
The mass of ingredient is given by 66g, 45g, 100g, 150g.
What is mass?
Mass is a parameter of measurement that calculates how much matter is contained in a body.
Mass is a physical quantity. Mass is measured in terms of the weight of a body. Gram, kilogram, and pounds are some standard mass units to measure it. The SI unit of mass is the kilogram; however, smaller objects are measured in grams.
Given, the ratio of the ingredients by mass as 2:2:1.
Let x be the mass of the ingredients.
A) total mass is given by 330g
therefore, 2x+2x+1x = 330
5x = 330
x = 330/5
x = 66
Hence the mass of oat = 2(66) = 132g
mass of cereal = 2(66) = 132 g
mass of nuts = 66g
B) 2x+2x+1x = 210
5x = 210
x = 210/5
x = 42g
Hence, the mass of oat = 2(42) = 84g
mass of cereal = 2(42) = 84 g
mass of nuts = 84
C) 2x+2x+1 = 500
5x = 500
x = 100
hence, the mass of oat = 2(100) = 200g
mass of cereal = 2(100) = 200 g
mass of nuts = 100g
D) 2x+2x+1 = 750g
5x = 750
x = 750/5
x = 150
Hence, the mass of oat = 2(150) = 300g
mass of cereal = 2(150) = 300 g
mass of nuts = 150g

When a family's ratio of income to poverty measurement is 1.05 , then the family is considered by the census bureau as rich.
How to illustrate the information?The "economy food plan," which is based on the U.S. Department of Agriculture, is used as the basis for an absolute poverty indicator in the country. The World Bank also uses an absolute definition of poverty. Extreme poverty is defined as surviving on less than $1.90 USD a day.
A ratio of less than 1 generally indicates that the income is below the poverty line. When the ratio is 1, income and poverty level are equal, and when the ratio is larger than 1, income is greater than poverty level. In this case, the family is rich.

The value of the expression is [tex]-2x^2[/tex]-8x + 6.
Given expression:-
[tex](2x^2-5x+4)-(4x^2+3x-2)[/tex]
We have to find the value of the given expression.
We know that, while subtracting quadrating equations, we subtract like terms from like terms.
Like terms
Like terms are those that contain the same variables raised to the same power. Only the numerical coefficients are different. In an expression, only we can combine like terms.
For example : While adding (5x + 3) and (4x - 5), we will add 5x to 4x and 3 to -4 to get the answer that is 9x - 1.
Hence, we can write,
([tex]2x^2-4x^2[/tex]) + (-5x -3x) + (4 -(-2)) = [tex]-2x^2[/tex] -8x + 6.

Find a relation between x and y such that the point (x, y) is equidistant from the point (2, -5) and (-2,9).
Answer:
(0,2)
Step-by-step explanation:
x = [tex]\frac{2-2}{2}[/tex] = [tex]\frac{0}{2}[/tex] = 0 We are finding the average of the x values (2 and -2)
y = [tex]\frac{-5+9}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 we are finding the average of the y values (-5 and 9)
The relation between x and y such that the point (x, y) is equidistant from point(2, -5) and(-2, 9) = 2x + 7y = -14
Points (2, -5) and (-2, 9).
let (x, y) be A
Let (2, -5) = (-2, 9) = B
Ax = Bx (length)
Squaring on both sides
Ax² = Bx²
By distance formula
(x - 2)² + (y +5)² = (x + 2)² + (y - 9)²
x² - 4x + 4 + y² +10y + 25 = x² + 4x + 4 + y² - 18y + 81
8x + 28y = -56
by multiplying both sides by 4
2x + 7y = -14
This is the relationship between the points (x, y) which is equidistant to A and B.
