4 0

Answer:

infinite solutions

Step-by-step explanation:

3x−5y=15

6x−10y=30 ​

Multiply the first equation by 2

2(3x-5y) = 2*15

6x -10y =30

The two equations are identical, which means they are the same line

That means they have infinite solutions

2. Let f(x) = 3x² -x+5, find f(x+1)​
Anna11 [10]

Answer:

f(x + 1) = 3x² + 5x + 7

Step-by-step explanation:

To find f(x + 1), substitute x = x + 1 into f(x), that is

f(x + 1) = 3(x + 1)² - (x + 1) + 5 ← expand (x + 1)² using FOIL

           = 3(x² + 2x + 1) - x - 1 + 5 ← distribute parenthesis by 3

           = 3x² + 6x + 3 - x - 1 + 5 ← collect like terms

           = 3x² + 5x + 7
