What is a linear equation in math?

  • A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
  • When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
  • There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.
  • Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.

\frac{3^{2} * 3^{-5}  }{4^{2} } = \frac{3^{-3} }{4^{-2} }

\frac{1}{3^{3} }  ÷  \frac{1}{4^{2} }

\frac{1}{27} * 16  = \frac{16}{27}

What is the product? (2y + 3) (3y^2 +4y + 5)
Furkat [3]

Answer:

6y³ + 17y² + 22y + 15

Step-by-step explanation:

(2y + 3)(3y² + 4y + 5)

6y³ + 8y² + 10y + 9y² + 12y + 15

6y³ + 8y² + 9y² + 10y + 12y + 15

6y³ + 17y² + 22y + 15

Which of the following sets of inequalities​
Ludmilka [50]

Inequalities help us to compare two unequal expressions. The correct options are 2 and 3.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The inequality for the red portion is,

slope, m = (-2/-4) = 1/2

y-intercept is 2.

y ≤ (1/2)x + 2

The inequality for the blue portion is,
slope, m = (5-0)/(3-0.5) = 2

y-intercept is -1.

y > 2x - 1

Hence, the correct options are 2 and 3.

I’m so confused on how to do this
dimaraw [331]

Answer:

19

Step-by-step explanation:

First:  Recognize that (f o g)(x) is the "composition" of two functions, where g(x) serves as the input to f(x).  We are given f(x) = 2x+3 and g(x) = x+5.  You could find g(3) right now:  it is g(3) = 3+5 = 8.  Use this 8 as the input to f(x):  f(8) = 2(8)+3 = 19.
