Answer:

-3 and 5

Step-by-step explanation:

f(n) = n² - 2n - 15

numbers whose product is -15 and sums up to -2 = -5 and 3

= n²- 5n+3n - 15

= n(n - 5) +3 (n - 5)

f(n) = (n + 3)( n - 5)

n + 3 = 0 n - 5 = 0

n = -3 n = 5

Roots = -3 and 5

At 3:00 p.m., Jamie leaves her house and drives north to the beach. She arrives at 5:30 p.m. Also leaving at 3:00 p.m., her brot
Ivenika [448]
Jamie took 2 hour and 30 minutes to reach the because 5:30-3:00=2hours and 30 minutes.Raul took 1 hour 30 minutes to reach state park because 4:30-3:00=1 hour and 30 minutes.Since they went in opposite directions you can add the time to get 4 hour.It would take 4 hours to go from the beach to state park.There speed was 60 miles per hour since 240/60=4/1 mph.

13. If l is parallel to m, find the values of x and y.
Delicious77 [7]

Answer: 14. x = 16; y = 23

15. x = 9; y = 13

Step-by-step explanation:

14. (4x + 4) = (7x - 44) (alternate exterior angles are congruent)

4x + 4 = 7x - 44

Collect like terms

4x - 7x = -4 - 44

-3x = -48

Divide both sides by -3

x = -48/-3

x = 16

39° + (8y - 43)° = 180° (consecutive exterior angles are supplementary)

39 + 8y - 43 = 180

Add like terms

-4 + 8y = 180

Add 4 to both sides

8y = 180 + 4

8y = 184

Divide both sides by 8

y = 184/8

y = 23

15. (15x - 26)° = (12x + 1)° (alternate exterior angles are congruent)

15x - 26 = 12x + 1

Collect like terms

15x - 12x = 26 + 1

3x = 27

Divide both sides by 3

x = 27/3

x = 9

28° + (12x + 1)° + (4y - 9)° = 180° (sum of interior angles of ∆)

Plug in the value of x

28 + 12(9) + 1 + 4y - 9 = 180

28 + 108 + 1 + 4y - 9 = 180

Add like terms

128 + 4y = 180

Subtract 128 from each side of the equation

4y = 180 - 128

4y = 52

Divide both sides by 4

y = 52/4

y = 13

Both answer and explantion.
