F = 1.8F + 32
F - 1.8F = 1.8F - 1.8F + 32
-0.8F = 32
-0.8F / -0.8= 32 / -0.8
F = -40
F'(x) is the derivative of f(x). the y value of derivative is the same
value as the slope of f(x) at whatever point your looking at so at x=1
the tangent line of f(x) will be horizontal (or zero) so f'(x)=0
Answer:
(f(x+h)-f(x))/h=(9(x+h)^2+8x+8h+2-9x^2-8x-2)/h=(9x^2+18xh+h^2+8h-9x^2)/h=18+8+h
Step-by-step explanation:
EXPLANATION
Let's see the facts:
$Sandwiches= 3*$Salads
Bill = $24.92
We can represent this in an equation:
Total Bill = Sandwiches + Salads
Let's call to Sandwiches "x" to Salads "y" and to Bill "B"
Then, the equation will be:
B = x+y = (3*y) + y
Applying distributive property:
24.92 = 3y + y
Adding similar terms:
24.92 = 4y
Dividing both sides by 4:
6.23 = y
Switching:
y=6.23
As we know, y variable represent the salads cost, so:
Answer is $6.23.
