The total amount raised is the sum of the amounts raised by the car wash and the dinner. The car wash raised 7c - 18. The dinner raised 6s - 45. We now add the expressions and combine like terms.
7c - 18 + 6s - 45
We need to combine like terms. Like terms are terms that have the same variables and the same exponents on the variables. 7c and 6s are not like terms since c and s are different variables. They cannot be combined together. Plain numbers, like -18 and -45 are lime terms because their variable parts are the same; they both have no variables.
7c - 18 + 6s - 45 =
= 7c + 6s - 18 - 45
= 7c + 6s - 63
Answer: C. 7c + 6s - 63
"Of the gravy" lol
To find the x-intercepts, you make f(x) = 0 and solve for x by setting each factor equal to 0.
0 = x(x + 1)(x - 5)(x - 7)
x = 0
x + 1 = 0
x = - 1
x - 5 = 0
x = 5
x - 7 = 0
x = 7
Your x-intercepts are x = - 1, 0, 5, 7
OR
There are x-intercepts at (- 1, 0), (0, 0), (5, 0), and (7, 0).
Answer:
6
Step-by-step explanation:







From the calculations above, we learn that line l and the curve intersect at (2, -6) and (1, -12). Next, we will set up a system of linear equations to solve for the slope and the y-intercept of line l.






Therefore, the slope of line l is 6.

Answer:
b
Step-by-step explanation:
4 2/3= 12/3+2/3=14/3
3 2/1=7/2 but you have to flip it
so you end up with 14/3*2/7
