For this case we have the following function:

<span>Deriving t</span><span>he function we have:
</span>

We now evaluate the function for the value of x = 5.
We have then:
Answer:
the derivative of f(x) = 4x + 7 at x = 5 is:
4
First you want to get it into standard form. which would mean you get the x of the side of the y and divide everything by the y's coefficient in this case 3.
3y-x=a
3y=x+a
y=1/3x+a
Now your going to want to turn this into a perpendicular li e which means you flip the coefficient and make it negitive
y=-3x+a
then we fill in the points.
-1=-3(2)+a
Solve
-1=-6+a
-1+6=a
5=a
Now put it in standard form.
y=-3x+5
This equation can be solved graphically by plotting the equations
f(x) = 3^x
and
g(x) = 5x-1.
The x-coordinate of the point(s) of intersection is the solution.
_____
On my graphing calculator, I find it easier to locate x-intercepts, so I would rewrite the equation as
3^x -(5x -1) = 0
and plot the function
h(x) = 3^x -(5x -1)
The x-intercept(s) would be the solutions. (There are two: x≈0.577, x=2.)
Answer:
-1
Step-by-step explanation:
Simplify the equation out.
y + 10 = -1x + 15
y = -1x + 5
We can use slope intercept form.
y = mx + b
We typically don't put a 1 in front of a variable, but for slope purposes, I put it.
So the slope (m value) would be -1.
The answer to 184/8 is 23. 8 goes into 184 23 times. I hope this helps!
