Answer:
y = 9
Step-by-step explanation:
the two sides are balancing so that means one 'x' and three 'y' equals four 'x' plus one 'y'
x + 3y = 4x + y
subtract 'x' from each side to get:
3y = 3x + y
subtract 'y' from each side to get:
2y = 3x
if 'x' = 6 then:
2y = 3(6)
2y = 18
y = 9
Answer:
Step-by-step explanation:
Answer:
(x² - 9)(x² - 2) = 0
x = 3 or √2
Step-by-step explanation:
To factor a polynomial, you need to find two expression that when multiplied together using FOIL (first, outside, inside, last) will produce the polynomial. In this case the polynomial
can be factored into:
(x² - 9)(x² - 2) = 0
Setting each of these expressions equal to '0':
x² - 9 = 0 or x² = 9 so √x² = √9 or x = 3
x² - 2 = 0 or x² = 2 so √x² = √2 or x = √2

Step-by-step explanation:
We are given that
In a freefall skydive, a skydiver begins at an altitude during free fall =10,000 feet
The skydiver drops towards earth at a rate=175 ft/s
The height of the skydiver from the ground can be modeled using the function

We have to find the domain of the function for this situation.
When t=0
Then ,
From given graph we can see that the value of t lies from 0 to 50.
Therefore, the domain of the function for this situation is given by
