1 answer:
Yuliya22 [10]3 years ago

Answer:

a. Parallel

b. Not parallel

Step-by-step explanation:

Systems which have no solutions are parallel lines. These lines do not intersect and therefore have no solution. Remember, parallel lines have the same slope. Compare the slope in each equation when in y=mx+b format to see if they are parallel.

a. y= 2x + 3                                                  y-2x=-3 becomes y = 2x - 3

m = 2                                                            m= 2

The slopes are the same so these are parallel lines.

b. 3x + y = 2 becomes y= -3x + 2               y = 1/3 x + 1/2

m = -3                                                          m= 1/3

The slopes are different so this is not parallel.

Since -3 and 1/3 are the negative reciprocals of each other. These lines are actually perpendicular.

Ramona went out with her 3 sisters, they spent $58 plus
Leto [7]
<h2>Problem:</h2>

Ramona went out with her 3 sisters, they spent $58 plus 9% tax on their meal. They also left 15% tip. If they divided up the bill evenly, how much did each of them spend?

<h2>Solution:</h2>

\frac{58 + 58(9\% + 15\%)}{3}

=  \frac{58 + 58(0.09 + 0.15)}{3}

=  \frac{58 + 58 \times 0.24}{3}

=  \frac{58 + 13.92}{3}

=  \frac{71.92}{3}

= 23.97

<h2>Answer:</h2>
