Answer:
y = 80 -40x
Step-by-step explanation:
The given equation shows the friend arrives at the restaurant (y=0) when x=2. That is, half the initial distance to the restaurant is covered in each hour of travel time.
If I take 2 hours to travel the 80 miles from my house, my distance will decrease at the rate of 40 miles per hour. My distance from the restaurant can be represented by ...
... y = -40x +80
Parallel lines and midpoint of a segment
This should be the answer
the answer is x+y≤2
The sum of x and y is greater than or equal to 2
The equation which can be used to represent "six added to twice the sum of a number and four is equal to one-half of the difference of three and the number” is option A) 6 + 2(x + 4) = 1/2(3 – x)
We have been given that "six added to twice the sum of a number and four is equal to one-half of the difference of three and the number”. Converting the words into equation we get
Here let x = be the number, then
6 + 2(x + 4) = 1/2(3 – x) (1)
Now as we look into the options,
Option A) is the correct option as it is the same equation as given in equation (1).
Option B) is incorrect as the equation it is stating is 6+2(x+4)= 1/2(x-3) which is not same as equation (1)
Option C) is incorrect as the equation it is stating is (6+2)(x+4)= 1/2(3-x) which is not same as equation (1)
Option D) is incorrect as the equation it is stating is (6+2)(x+4)= 1/2(3-x) which is not same as equation (1)
Hence option A) is the correct answer
