W = unknown number
7w - 8 = 3 (product of 7 and a number, w, subtract 8) is 3
7w = 11
w = 11/7
Answer:
(-6,-14)
Step-by-step explanation:
Answer:
The correct answer is y = 9
Step-by-step explanation:
It is given that,
12/(4y + 6) = 2/7
<u>To find the value of y</u>
12/(4y + 6) = 2/7
By cross multiplying,
12 * 7 = 2 * (4y + 6 )
84 = 8y + 12
8y + 12 = 84
8y = 84 - 12
8y = 72
y = 72/8 = 9
y = 9
Therefore by solving the given expression we get the value of y = 9
To find the derivative, you must use the chain rule.
If u=x^3+2x:
dy/dx=(dy/du)(du/dx)
dy/du=d/du(e^u)=e^u=e^(x^3 + 2x)
du/dx =d/dx (x^3+2x) = 3x^2 + 2
So dy/dx=
e^(x^3+2x) * (3x^2+ 2)
Answer:
Step-by-step explanation:
Let
h(t) ---> the height of an object in meters
t ----> the time in seconds
we have
For t=6 sec
substitute in the quadratic equation the value of t and solve for h
