Answer:
10n + 28
Step-by-step explanation:
a + d (n-1)
a = 38
d = 10
38 + 10 (n-1)
38 + 10n -10
10n +38 - 10
10n + 28
Hope this helps!
Answer:
Step-by-step explanation:
Remember that the derivative tells us the slope of the tangent line at a given point.
So, we want to find the equation of the tangent line to f(x) at x=8.
We are given that f'(8) is -10.
In other words, the slope of the tangent line to f(x) at x=8 is -10.
We also know that f(8)=9. In other words, we have the point (8,9).
So, we can use the point-slope form to figure out the equation:
Substitute -10 for m and let (8,9) be (x₁, y₁). So:
Distribute the -10:
Add 9 to both sides:
And we're done!
Answer:
17m
Step-by-step explanation:
Add up 4m and 4.5m. 8.5
Multiply that number by 2. 17
What do ya got? I need the equation and a little explanation of what needs to be done.
Answer:
f(x)=-3(x+2)^2-2
Step-by-step explanation: the the FX graph the -3 in my equation represents the decrease(for being negative) in the graph, the positive 2 represents the x axis if that number is positive the negative 3 is going to change the x axis then will end up being negative which is why the x starts off in negative 2, the last number represents the y axis if the y axis is negative 2 the y will start off at -2
