The graph of a linear equation contains the points (3,11) and (-2,11). Which point also lies on the graph?(YOU MUST SHOW WORK)
dexar [7]
Y= ax+b

when x=3, y=11   and when x= -2, y=11
          3a+b=11
          -2a+b=11    | * -1
3a+b=11
2a-b=-11
------------
  5a=0, a=0:5, a=0
⇒ b=11
y=11 for every x
So ( 1,11)  or (2,11) are also points on the graph

a mower uses 5/16 gallon of gas to mow the back yard. the side yard is only 2/3 the size of the backyard. How much gas will be n
Trava [24]

Answer:

(5/24) gallons of gas to mow the side yard

Step-by-step explanation:

We can easily solve this proble by applying a rule of three

5/16 gallons of gas  ---------------------------------  for 1 backyard

x  gallons of gas ------------------------------------- 2/3 backyard

x = ((2/3)/1)*(5/16) gallons of gas

x = ((2/3))*(5/16) gallons of gas

x = ((10/48) gallons of gas

x = (5/24) gallons of gas
