Answer:
The term that represent the amount of money she will spend on brownies is 2b
Step-by-step explanation:
Let
c ----> the number of cones
b ----> the number of brownies
we know that
The cost of desserts can be found using the expression

where
4c ----> is the term that represent the amount of money spend in cones
2b ----> is the term that represent the amount of money spend in brownies
5 ----> is the term that represent the amount of money spend in water
therefore
The term that represent the amount of money she will spend on brownies is 2b
That means ---> the number of brownies (b) multiplied by the cost of each brownie ($2)
You need to subtract everything to the left side and set it equal to zero. Combine like terms.
Then, the coefficient of x^2 is a, the coefficient of x is b, and the constant term is c.
4x^2 - 5 = 3x + 4
4x^2 - 3x - 5 - 4 = 0
4x^2 - 3x - 9 = 0
a = 4; b = -3; c = -9


The answer is going to be 9. Hope that helped.
To find slope use the formula M = y2 - y1
-----------
x2 - y1
say you were given this (2,3) (-4,5) 2 would be x1 and 3 would be y1, -4 would be x2 and 5 would be y2 then just put it into the formula 5 - 3
--------
-4 - 2
which would be 2/ -6 which would simplify to 1/3
