Find value of y when x equals 13 -3x-2y=--25

y = - 7

substitute x = 13 into the equation and solve for y

(- 3 × 13 ) - 2y = - 25

- 39 - 2y = - 25 ( add 39 to both sides )

- 2y = - 25 + 39 = 14 ( divide both sides by - 2 )

y = = - 7

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

step-by-step explanation:

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
