Plug in the values 1,4, and 9 into the equation one by one. Plug it in as the x value.

y=-1/2 times root 1 = -1/2
(x,y)=(1,-1/2)

y=-1/2 times root 4 = -1
(x,y)=(4,-1)

y=-1/2 times root 9 = -3/2
(x,y)=(9,-3/2)

The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.

Step-by-step explanation:

Given,

Start up fee to receive internet = $30

Charlie wants to swim across a river that's is 400 meters wide. He begins swimming perpendicular to the shore he from but ends u

nirvana33 [79]

Let's calculate Charlie swimming distance. Assume Charlie swimming distance is D.
D^2 = 400^2 + 100^2 => D = 412 meters

Assume d is Carter's distance.
d^2 = 400^2 + 150^2 => d = 427 meters

Carter swims more than Charlie by:
d - D = 427 - 412 = 15 meters
