Answer:
1) D: All of the above.
2) A: No solution
3) B: One solution
Step-by-step explanation:
<h3>1. The systems of linear equations can be solved through the following methods: </h3>
Graphing method: Using the slope and y-intercepts of each equation to plot points and graph the lines to see whether the given system has a <u>point of intersection</u> as a solution.
Elimination method: this involves either <u>adding</u> (when the coefficients have opposite signs) or <u>subtracting</u> (when the coefficients have the same sign).
Substitution method: involves solving for one of the variables of either equations, and substituting the values of that expression into the other linear equation in the system.
Therefore, the correct answer is Option D: All of the above.
<h3>2. Graph of Parallel Lines:</h3>
Given the graph of parallel lines, which means that they will never have a point of intersection. Therefore, the given systems of linear equations have no solution. Therefore, the correct answer is Option A: No solution.
<h3>3. Graph of Two Intersecting lines</h3>
Given the graph of two non-perpendicular intersecting lines, it means that they have <u>one point of intersection</u> that represents the <em>solution</em> to the given system.
Therefore, the correct answer is Option B: One solution.
2x + 39 = 77 is the equation trnaslated, thne you subtract 39 from both sides to get 2x = 38 then divide both sides by 2 to get x = 19. the number is 19

"Simplifying a complex fraction" means Simplifying a complex fraction means to rewrite the fractions in the numerator and in the denominator with common denominators.
Step-by-step explanation:
A complex fraction is one where either the numerator or the denominator or both contains common a fraction.
There are two methods to simplify a complex fraction-
First Method
- We simplify the numerator until we have one single fraction.
- Then we simplify the denominator until we have one single fraction.
then we divide by multiplying the numerator by the reciprocal of the denominator.
- The end result is simplified
Second Method
- Firstly we find a common denominator of all the fractions in the numerator and all the fractions in the denominator .
- Then we multiply the number in the numerator and denominator of the complex fraction by a common denominator found in step 1.
- The result is simplified
