Answer:

Step-by-step explanation:

An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant

A constant rate of change is a rate of change that stays the same and does not change.

A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line called y-axis and a horizontal line called x-axis.

Direct variation describes a simple relationship between two variables .

Distributive Property  is multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Inequalities a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to.

Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points.

An opposite reciprocal is the fraction form of a number flipped upside down (that's the reciprocal part), and with its sign changed (that's the opposite part).

The origin is the point where the axes of the system intersect.

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

The slope of a line is a measure of its steepness.

A solution is an assignment of values to the unknown variables that makes the equality in the equation true.

Square Root a factor of a number that, when multiplied by itself, gives the original number

system of equations is a set or collection of equations that you deal with all together at once.

Variable  is standing in for an unknown numerical value in an equation.

The x-axis is the horizontal plane of a graph

The x-intercept is the point where a line crosses the x-axis.

The Y-axis is The line on a graph that runs vertically (up-down) through zero

The y -intercept of a graph is the point where the graph crosses the y -axis

The domain of discourse is sets. Suppose some predicate Q is true for all elemenst of A: ∀a ∈ A Q(a). Recall the definition of s
Sloan [31]

Answer:

See the step-by-step explanation

Step-by-step explanation:

Let c be any element of C. (I'm not sure wether you have to assume that C is non-empt or not)

C is a subset of B. That means that as c is  in C, it is also in B. (c \in C \Rightarrow  c \in B)

Now, B is a subset of A. It follows that as c \in B \Rightarrow c \in A.

That means c is an element of A. The predicate Q is true for all elements of A, including c.

Because we let c be any element of C, we have proven that the predicate Q is true for all elements in C.

Help ! solve the following system of equations <br><br> -9x+2y=-13<br><br> 2x-9y=20
Stella [2.4K]

Answer: x = 1, y = -2

Step-by-step explanation:

-9x+2y=-13

x= 13/9 + 2/9y

2x-9y=20

2(13/9+2/9y)-9y=20

<em>Substitute y with -2.</em>

<em />

x= 13/9+2/9(-2)

<em>After solving you'll see that 1 is a possible solution for x.</em>

<em />

Check your answer

-9x+2y=-13

-9x1+2(-2) = -13

2x-9y=20

2x1-9(-2) = 20

-13 = -13

20 = 20

Therefore, x=1 and y=-2
