One's a parabola, one's a line, so they should intersect in two places.

Table of values:

for x = 1,2,3,4,5,6
f(x) = 3,0,-1,0,3,8
g(x) = -1,0,1,2,3,4

Now all you need to do is look where they have the same (x,y) values.

This is at (2,0) and (5,3).

If 1/a + 1/b =1/c and ab=c,what is the average of a and b?
goblinko [34]
If we solve the left side of the given equation,
                                  1/a + 1/b = 1/c
 we get an answer of,
                                    b+a / ab = 1/c
Since ab = c, we can conclude that b + a is 1. The average of these two numbers is equal to there sum divided by 2. The answer is therefore equal to 0.5.

Josefina pain rent for 5 months. She paid a total of $2045. how much did she pay per month?
djverab [1.8K]

Answer:

$409 per month

Step-by-step explanation:

If josefina paid $2045 over a time period of 5 months, then we have to divide how much she paid ($2045) by 5 to find out how much she paid for rent in 1 month.

We can use the equation: 2045 ÷ 5

When we solve that equation, we get 409 which means that josefina paid $409 per month for rent.

(sorry if this is confusing but I hope it helped)
