Answer:
Hey there!
For the first one:
Chips: x
Pretzels: 3x
Nachos: 3x-2
Total snacks: x+3x+3x-2=7x-2
For the second one:
In the equation, 150+5d, 150 represents the starting amount of money, in this case, 150 dollars. 5d means that for every day, five dollars get put into his account.
For the third one:
In this equation, 1.50 represents to initial fee, and 2.25m represents the cost per mile. Dividing by 2 gives us what each person in the cab pays.
Let me know if this helps :)

Answer:
6
Step-by-step explanation:
We want to evaluate:
8a-1+0.5b
When a=1/4 and b=10.
We simply substitute the given values of as and b into the given expression,

The value of the expression is 6 for the give values of a and b.
Answer:
-3 is the value of k in g(x)=kf(x)
Step-by-step explanation:
Both functions cross nicely at x=-3 so I'm going to plug in -3 for x:
g(x)=kf(x)
g(-3)=kf(-3)
To solve this for k we will need to find the values for both g(-3) and f(-3).
g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.
g(-3)=-3
f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.
f(-3)=1
So our equation becomes:
g(-3)=kf(-3)
-3=k(1)
-3=k
So k=-3.
Answer:
a)
D. y = (x +1)(x + 3)
b)
C. 3x ( x - 3) = 0
