Answer:
(1,4)
Step-by-step explanation:
Which ordered pair is a solution of the equation? y = 7 x − 3
a. (1,4) b. (-1,-4) c. both d. neither
Solution
y=7x-3
Solve by trying each ordered pair
a. (1,4)
x=1, y=4
Substituting the value of x and y into the equation
y=7x-3
4=7(1)-3
4=7-3
4=4
This is a true statement
b. (-1,-4)
x=-1, y=-4
Substitute the value into the equation
y=7x-3
-4=7(-1)-3
-4= -7-3
-4= -11
This is not a true statement
This true statement is when x=1 and y=4
So, the ordered pair (1, 4) is the solution
Amount of milk drunken: (4 children)(0.5 gall per week per child)
Multiply the result of the above calculation by ($2.89 / gallon):
4(0.5)($2.89) = $5.78 per week milk expenditure
ANSWER
EXPLANATION
The given equation is
Take antilogarithm of both sides to base e.
This will simplify to
Group like terms to obtain,
Take square root of both sides to get,
