Y varies inversely with x.
⇒ y = k/x

When y = 5, x = 50
5 = k/50
k = 50 x 5 = 250

Equation: y = 250/x

When x = 10
y = 250/10 = 25

Answer: k = 250, y = 25 when x = 10

The cost of the car is $27,546

<h3>How to calculate the cost of the car ?</h3>

Therefore the cost of the car can be calculated as follows

7/100 = 0.07

1928.22/0/07

= 27,546

Hence the cost of the car is $27,546

G=-4x-4, solve for x
Snowcat [4.5K]

Answer:

G = -4x - 4

x = -1

Step-by-step explanation:

step 1: flip your equation and turn G into zero

ex: -4x - 4 = 0

step 2: add 4 to both sides

ex: -4x - 4 + 4 = 0 + 4   (-4x = 4)

step 3: divide both sides by -4

ex: -4x/-4 = 4/-4   (x = -1)

step 4: plug -1 into x then solve to check your answer

ex: -4(-1) - 4 = 0

4 - 4 = 0

0 = 0 (when this says 0 = 0 then that means your answer is always true)
