Here you have black dots at x = {0, 1, 2, 4, 4.5, 5}.

For each of these x-values, there is one and only one associated y-value. This fact tells us that the graph does represent a function.

Determine whether each equation has one solution, no solution, or infinite solutions.

Sati [7]

Answer:

a. has one solution

b. infinite solution

Step-by-step explanation:

2(x - 1) + 6 = 4x - 22

2x - 2 + 6 = 4x - 22

2x - 4x = 2 - 6 - 22

-2x = -26

x = 26/2

x = 13

6(2x + 1) – 2 = 12x + 4

12x + 6 - 2 = 12x + 4

12x - 12x = 4 + 2 - 6

0 = 0

Can someone help me with this question????

Answer:

Hi! I think I got the answer, it is a tricky one! The answer I got was C) 1029.

Step-by-step explanation:

1. It is good to first know that 40%more means 1.4 (some number). So, if n is 40% more than the sum of the other three numbers: n= 1.4* (l +m+p) .

2. Also note that: n+l+m+p= 1764; so, n = 1764-l-m-p.

3. Since we have two expressions for n, we can equate them to each other. Giving, 1.4* (l +m+p) =1764-l-m-p . Simplifying we get 2.4 (l +m+p)=1764.

4. l +m+p =1764/2=735.

5. 1764-735=1029

Hope that helps! Feel free to message back if there are any questions!
