Answer:
-8±√17 and -8±6√2
Step-by-step explanation:
1. x+16/x=4, x^2+16-4x=0. x=-8±√17
2. x+16/x=8, x^2+16-8=0. x=-8±6√2
Although the concept here is physics, the solution is technically just algebra. You have two situations that are related to each other which can be expressed in equation form. Actually, the equation is already given which is <span>7/12 w= 13 5/12. So, basically, all you have to do is solve for w.
Let's simplify 13 5/12 first into an improper fraction.You do this by multiplying the denominator with the whole number and adding to it the numerator. This will be your new numerator, The denominator would still be 12. So, this is equal to (12*13 + 5)/12 = 161/2. Then,
(7/12) w = 161/12
By cross multiplication,
7*12*w = 161*12
w = 161/7 = 23
Therefore, w = 23 pounds which is the weight of the object on Earth.

Step-by-step explanation:
Answer:

Step-by-step explanation:
Given:
Original price of the ticket is 
Price after using the coupon is 
Coupon discount is 85% of
Therefore, the price after applying coupon is given as the difference of the original price and the coupon discount. That is,

The graph is shown below. The graph passes through the origin as the above relationship is a proportional relationship.
The line
strictly remains in the first quadrant as both
and
can't be negative as they represent price of tickets and price can never have negative values. Hence, only the first quadrant has both the values of
and
positive.
