This problem can be done by using long division. Using long division via online is quite hard.
Explanation:
Model: 1903
5 inches= 16 feet
wingspan=12.5 inches
In feet is the actual wingspan. Basically you set up an equation
Next you can cross multiply which is 5*y / 16*12.5 and get 5y=200
After you isolate y by dividing by 5 on both sides.
Y=40
Answer: The wingspan of the actual flyer is 40 feet.
Answer:
Identity- An equation that is true for all real numbers for which both sides are defined is called a(n) Identity
Step-by-step explanation:
Plug in x-values and see which one has an incorrect y value.
(x, y)
x=0; y=0+7=7; CORRECT
x=2; y=2+7=9; INCORRECT
x=9; y=9+7=16; CORRECT
x=12; y=12+7=19; CORRECT
The point that is not on the online is (9, 16).
