P = 11 + 4 + 18 + 37 + 7 + 19 = 96
a = (18*7) + (11*19) = 126 + 209 = 335
3. constant - D. a numerical value
2. coefficient - A. the constant preceding the variables in a product
4. expression -E. a mathematical phrase....
5. variable - B. a letter... representing an unkown
1. algebraic expression - C. a mathematical expression...
hope this helps
Rent all
55.5/3 = 18.5
74/4 = 18.5
it costs 18.5 per day
1. y = 18.5 x where y =cost and x=days
A-1
10.99 per 1/2 day
10.99 * 2 =21.98 per day
2. it costs 21.98 per day from A-1
Rentall is the better deal because it is only 18.50 per day versus 21.98 per day
Answer:
-7x - 2
Step-by-step explanation:
First, find the new slope that is perpendicular.
1/7 -> 7 -> -7
So far, we have -7x + b. (we use mx + b)
Since you asked for it to pass point A (-1, 5), substitute in x and y.
y = -7x + b
5 = -7(-1) +b
5 = 7 + b
b = -2
So the equation would be -7x - 2.
Your welcome!
