Determine the slope and y-intercept of the graph:
2x + 5y = 10

Answers

Answer 1
Answer:

Slope is -2/5 and y-intercept is 2

Step-by-step explanation:

  • Step 1: Write the equation in slope-intercept form y = mx + b

2x + 5y = 10

5y = -2x + 10

y = -2/5 x + 10/5

y = -2/5 x + 2

  • Step 2: Find the slope and y-intercept from the equation.

Slope, m = -2/5

y-intercept, b = 2

Susie earns $9 per hour at her part-time job. On Tuesday, she spent $5 of her pay that day on lunch. If she took home $49 that day, how many hours did she work? Which mathematical sentence matches the problem?5h + 9 = 49
9h + 5 = 49
9(h - 5) = 49
9h - 5 = 49

Answers

9h - 5 = 49 is the corret answer 

Your variable represents the number of hours she worked, not the number of times she spent 5 dollars.

Step-by-step explanation:

There are 8 pencils in a package. How many packages will be needed for 28 children if each child gets 4 pencils?

Answers

Answer

Find out the  how many packages will be needed for 28 children if each child gets 4 pencils .

To prove

As given

There are 8 pencils in a package .

Total number of childrens = 28

each child gets 4 pencils

Total number of pencils needed for 28 children = 28 × 4

                                                                               = 112

Now find out the Number of packages for 28 children .

Number\ of\ packages\ needed\ for\ 28\ children =(Total\ numer\ of\ pencils\ needed)/( pencils\ in\ a\ package)

As

Total number of pencils needed = 112

pencils in a package = 8

put in the above

Number\ of\ packages\ needed\ for\ 28\ children = (112)/(8)

Number of packages needed for 28 childrens = 14

Therefore the 14packages will be needed for 28 children if each child gets 4 pencils .
The question is asking to state or calculate how many package will be needed for 28 children if each child gets 4 pencils, base on my calculation, I would say that the answer would be 14 pencils. I hope you are satisfied with my answer and feel free to ask for more if you have questions
