Answer:
To simply a equation you need to use Pemdas
the order of operations.
We need to simplify parethesis first...
if you cant simplify in it like (x+3)
you need to use the distributive property
-2 *x
-2*3
Answer:
81
Step-by-step explanation:
subtract 3 from both sides->x^1/4=-3
set both sides to the power of 4-> x=(-3)^4
solve-> x=81
The first one is neither
No. 2 is perpendicular ( because slope = -1/ slope of the other)
No 3 is parallel (both have slope of 3/4)
No 4 is perpendicular.
Answer:
6
Step-by-step explanation:
6
Answer:
an = 7 + 5n
Step-by-step explanation:
First we know that for each number of days rented the cost increase by 5 so we get an - (?) + 5n.
We also know the first number is 12 for 1 day, so for 0 days, or the starter cost, is 7. We get this by subtracting 5 from 12.
Hence the answer an = 7 + 5n
