Given y=x2 + 9x + 20 find the zeroes.

Answers

Answer:

x=-5   x=-4

Step-by-step explanation:

y=x^2 + 9x + 20

We need to factor the equation

What 2 numbers multiply to 20 and add to 9

4*5 = 20

4+5 =9

y=(x+5) (x+4)

To find the zero's we set the equation equal to zero

0= (x+5) (x+4)

Using the zero product property

x+5 = 0   x+4=0

x=-5   x=-4

A bicyclist rides 1/5 mile in 1/65 hour. Write this rate as a unit rate.

Answers

1/5 over 1/65 hour. as in 1/5 divided by 1/65 hr

Final answer:

The unit rate of the bicyclist's speed is found by dividing the distance covered (1/5 mile) by the time spent (1/65 hour). The result is 13 miles per hour.

Explanation:

In this problem, you're asked to find a unit rate. A unit rate is a rate in which the second term is 1. So, to find a unit rate, you divide the first term with the second term.

In this case, the bicyclist's rate is 1/5 mile in 1/65 hour. If you divide 1/5 by 1/65, you find the rate of bicycle speed per 1 hour, which is the unit rate:

1/5 miles divided by 1/65 hours = (1/5) * (65/1) = 13 miles/hour

So, the bicyclist's unit rate is 13 miles per hour.
