<h3>
There are 3 answers: Choice A, Choice D, Choice F</h3>
Explanation:
2 & 1/2 = 2.5
10 + (-2.5) can be represented by starting with 10 and then dropping by 2.5, which is what choice A is saying
or we can start with -2.5 and add on 10. This works because we can add numbers in any order, example: 2+3 = 3+2 = 5. So starting with -2.5 and adding on 10 is represented by choice D's and choice F's examples
The x intercept of the graph of the function below would be the letter
D. (-8,0) and (4,0)
1/8 + 1/9 = 9/72 + 8/72 = 17/72
Use the slope formula, do the same for each question.
Slope= y2-y1/x2-x1
Question 4: (-1,-2) and (1,0)
-1 is x1, -2 is y1
1 is x2, 0 is y2
0- -2=2 (0 subtract -2, two minus signs equal to an addition sign.)
1- -1=2
2/2= 1
The slope is 1.
