(3,2). 3^2 + 2^2 = 13 2(3)-2= 4 Works for both, hence this is the intersecting point of the two lines.
Answer: x = -1
Step-by-step explanation:
You are trying to figure out what the missing number is that will make 4
so we know that only 2 plus or multiplied by 2 can = 4
and because 2 is outside the parentheses it has to be multiplication meaning that x + 3 has to equal 2
4 = 2(x+3)
4 = 2 ( -1 + 3)
4 = 2 (2)
2 * 2 =4
4 = 4
