Answer:
The Answer is: The first number is 10 and the second number is 8.
Step-by-step explanation:
Let f = first number and s = second number.
The first number is 2 larger than the second:
f = n + 2
The numbers times each other is 80:
f * n = 80
Substitute the value of f, which is (n + 2):
n(n + 2) = 80
n^2 + 2n = 80
n^2 + 2n - 80 = 0
(n + 10)(n - 8) = 0
n^2 + 10n - 8n - 80 = 0, so the first number is 10 and the second one is 8.
Another method, just from thinking about it:
factor 80:
8 * 10, is the first factoring I thought of. I then noted that the difference between the two is 2 and if you multiply them they equal 80.
Hope this helps! Have an Awesome Day!! :-)
Answer:
To solve this I would multiply both sides by 3
Step-by-step explanation:
i would use the multiplication property of equality
If there is parenthesis, you must do the parenthesis first. If there’s no parenthesis, do the division from left to right.
Answer:
The equation of the tangent line is 
.
Step-by-step explanation:
Firstly, we obtain the equation for the slope of the tangent line by implicit differentiation:
(1)
If we know that 
, then the slope of the tangent line is:
By definition of tangent line, we determine the intercept of the line (
):
(2)
If we know that 
and 
, then the intercept of the tangent line is:
The equation of the tangent line is .
