2y = 2x-4<br> y + 3x = 10<br><br> (substitution)
devlian [24]

Answer:

x = 3, y = 1

Step-by-step explanation:

2y = 2x - 4, so y = x - 2. Substituting this into the bottom equation and solving for x:

x - 2 + 3x = 10

4x - 2 = 10

4x = 12, so x = 3 and y = 1.

PLEASE HELP!!! Classify each real number. List all the subsets in which the number belongs.
Marat540 [252]

Answer:

9^3 is Natural, Whole, Integer, and Rational

7/4 is Rational

√3 is Irrational

0 is Whole, Integer, and Rational

Thinking Process:

Alright, to start, with 9^3, it equal 729. This is a natural, whole, integer, and rational number. It is a natural number because it follows the counting (1, 2, 3...etc). Because of this, it is also part of all of the other rational categories as well.

With the next one, 7/4, this equals 1.75. It is not a natural, whole, or integer number because it is a decimal. However, it is rational, because it is still definite.

Next, with √3, this equals 1.73205.... It is irrational because it is not definite as it is a sequence of numbers that go on forever, being unpredictable in nature.

Last is 0, it is not a natural number because it does not follow the counting (1, 3, 3...etc). But it is whole because it follows the counting (0, 1, 2, 3...etc). This is along with it being an integer and rational because of this.

Describe the continuity of the graphed function. Select all that apply.
victus00 [196]

Using continuity concepts, it is found that the correct options are:

  • The function is continuous at x = -4.
  • The function has an infinite discontinuity at x = -1.

-----------------------------

A function f(x) is continuous at x = a if:

\lim_{x \rightarrow a^{-}} f(x) = \lim_{x \rightarrow a^{+}} f(x) = f(a)

-----------------------------

  • At x = -4, there are no changes in the definition of the function, thus, it is continuous.
  • At x = -1, we have that:

\lim_{x \rightarrow -1^-} f(x) = 0

\lim_{x \rightarrow -1^+} f(x) = f(1) = 1

  • A different definition depending on the which side of -1 the function is, thus, it is a jump discontinuity.
