2 gallons left after driving 50 miles

Step-by-step explanation:

Edgar has 7 gallons of gas remaining in his car after driving for 30 miles he had 4 gallons left in the tank

Initially he has 7 gallons of gas

after 30 miles 4 gallons left

Let m be the number of miles and g be the gallons left

(0,7)  (30,4)

find slope using formula

y intercept b= 7

so equation becomes

now find out g when m= 50 miles

so 2 gallons left after driving 50 miles

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
