Answer:

1.) a line parallel to the line will have slope 2/3

2.) a line perpendicular to the line will have slope -3/2

Step-by-step explanation:

The slope of parallel lines must always be the same. Therefore, if a line is parallel to y = 2/3x - 4, the other line must have slope 2/3 and not have the same y-intercept (otherwise it would represent the same line).

The slope of perpendicular lines are reciprocals with opposite signs. Basically, if you have one slope of one equation, to find the perpendicular slope you would simply flip the slope over and change the sign.

For example: if the slope was 2/3, the perpendicular slope is flipping 2/3 upside down to get 3/2 and changing the sign from positive to negative = -3/2

Natali [406]

Answer:

The amount of rabbit after 1 year will be 320.

Step-by-step explanation:

A gardener brought 5 rabbits, after 2 months rabbits became 10.

The growth continues on the same ratio.

This represents a geometric sequence with 1st term as 5 and common ratio as 2.

As we have to find the amount of rabbit after 1 year, so the we have to find $\dfrac{12}{2}+1=6+1=7$ th term. As the time difference between each counting is 2 months, so we divided 1 year or 12 months of time by 2.
