Answer:
The slope is 0
Step-by-step explanation:
y1 - y2 over x1 - x2 gives you solpe
2 - 2 over 3 - (-1)
2-2 = 0
3 - (-1) = 4
0/4 is 0
Yes. In fact, that is basically the definition of a derivative. It is the instantaneous rate of change of a function.
For example, picture the graph of the following function:
The slope is constantly changing at every x-value, so to find the slope at x=a, we find the derivative of the function.
Once we have the derivative, simply plug in a for x to find the slope of the line tangent to f(x) at x=a.
For example, at x=5:
The slope of f(x) at x=5 is 10.
Because ratios can be written as fractions

172 -
=
76.44 mulch = x amount of gravel = 172
Gravel = 172 - 76.44
= 95.56

Answer:
(A) 30x+90=300
(B) $7
Step-by-step explanation:
Let x be the roller skating rink's entrance fee for one student.
So, the entrance fee for 30 students=30x
As each student pays a $3 fee to rent skates
So, the fee for rent paid by 30 students= $3x30=$90
The total cost for the students to enter the rink and rent skates= 30x+90
As given that total fee to enter the rink and rent skates is $300.
Therefore, 30x+90=300
(A) The required equation is 30x+90=300.
(B) On solving the equation, we have
Hence, the roller skating rink's entrance fee is $7.
