Remember the order of operations, pemdas, add 5ab and 9ab to get 14ab, then subtract to get 13ab
Answer:
19
Step-by-step explanation:
you begin with the innermost parentheses, which is 9-6
9-6=3
you then move to the brackets, which has the 2 and tour answer from before, 3. You multiply 2 and 3 and get 6. You then add the 6 plus the 13 on the outside.
13+6=19
Answer:
x = -1, 3
Step-by-step explanation:
so what you need to do is graph each one because that's what the questions ask. One way for you to check your answer is to set the two equations equal to each other.
-x + 5 = x^2 - 3x + 2
you want to end up with one equation and having the equation equal 0. So add x to both sides to cancel out the x on the left side and then subtract 5 from both sides to cancel out the 5 on the left side.
0 = x^2 - 2x - 3
now you factor
0 = (x - 3) (x + 1)
x = -1, 3
