On a coordinate plane, the endpoints of line segment jk are j(−10,12) and k(8,−12). point l lies on line segment jk and divides it into two line segments such that the ratio of jk to kl is 5: 1.

what are the coordinates of point l ?
a
(4.4,−7.2)
b
(−7,8)
c
(−6.4,7.2)
d
(5,−8)

The coordinates of point L are (4.4 , -7.2) ⇒ answer A

Step-by-step explanation:

Assume that point L is (x , y)

Point L divides the line segment JK into two line segments such that

the ratio of JK to KL is 5 : 1

The coordinates of point J are (-10 , 12)

The coordinates of point K are (8 , -12)

∵

∵

Let = (-10 , 12) and = (8 , -12)

and = JL : KL

∵ JK : KL = 5 : 1

∵ JK = JL + KL

∴ 5 = JL + 1

Subtract 1 from both sides

∴ JL = 4

∴ JL : LK = 4 : 1

∴ = 4 : 1

∵

∴

∴

∴ The x-coordinate of point L is 4.4

∵

∴

∴

∴ The y-coordinate of point L is -7.2

* The coordinates of point L are (4.4 , -7.2)

there are no figures how am i supposed to answer this question

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
