Alex is conducting a survey for a car company. She decides to start by interviewing some people in her neighborhood.

She prepares a questionnaire and emails it to 50 neighbors who own cars. Of those neighbors, 24 respond.

Two intersecting lines have zero, an infinite number, two, or one of the same points in common?

Answers

If two lines intersect, then there are two possibilities

A) The lines intersect at exactly one point. This happens if the slopes of the two lines are different (the y intercepts may or may not be the same).

B) The lines intersect at infinitely many points. This happens when both slopes are the same and when both y intercepts are the same. In short, the two equations are identical. Often they may be written in different forms. For example, the equation y = 2x+1 and 2y = 4x+2 are the same equation. Divide everything in equation (2) by 2 and you'll get equation (1).

A fruit stand has to decide what to charge for their produce. They decide to charge $5.30 for 1 apple and 1 orange. They also plan to charge $14 for 2 apples and 2 oranges. We put this information into a system of linear equations.Can we find a unique price for an apple and an orange?

Answers

Answer:

We cannot find a solution to the system of equations.

a+b = 5.30

2a + 2b = 14

Step-by-step explanation:

Let a = the price of an apple

let b = price of an orange

a+b = 5.30

2a + 2b = 14

Multiply the first equation by 2

2a+ 2b = 10.60

Subtract the second equation

2a+2b = 10.60

-2a+2b = 14

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

0 = -3.40

This is never true so there is no solution
