(2,-2)(5,7)
7-(-2)= 9
5-2= 3
9/3= 3
slope = 3
(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
Answer:
Step 1 is incorrect

We will solve each expression step by step:
<span>
Expression 1:
-12x4 + 7x3 + 6x4 - 2x3
x4 (-12 + 6) + x3 (7-2)
-6x4 + 5x3
Answer:
5x ^ 3 - 6x ^ 4
Expression 2:
-5x3 + 7x4 + 4x4 - 8x3
x4 (7 + 4) + x3 (-5-8)
11x4 - 13x3
Answer:
11x ^ 4 - 13x ^ 3
Expression 3:
-2x4 - 10x3 + 4x4 - 2x3
x4 (-2 + 4) + x3 (-10-2)
2x4 - 12x3
Answer:
2x ^ 4 - 12x ^ 3
Expression 4:
15x3 - 15x4 + 13x4 - x3
x4 (-15 + 13) + x3 (15-1)
-2x4 + 14x3
Answer:
14x ^ 3 - 2x ^ 4
Expression 5:
7x4 - 15x3 + 12x3 - 2x4
x4 (7 - 2) + x3 (-15 + 12)
5x4 - 3x3
Answer:
5x ^ 4 - 3x ^ 3</span>
52 and 54. Integers are whole numbers meaning 1..4..7..17...25 and so on. Consecutive meaning one right after the other. So 52 and 54 are the answer.
