So starting with the y-intercept, the easiest method to find it is to convert this standard form equation to slope-intercept form. Firstly, add 5x to both sides:
Next, divide both sides by -4 and your slope-intercept form is
Looking at this slope-intercept form, <u>the y-intercept is (0, -5/2).</u>
Now to find the x-intercept, just set the y-variable to zero and solve:
<u>Our x-intercept is (-2,0).</u>
Alright, lets get started.
The length of each section what carpenter needs to cut is 3 feet and 8 inches.
Converting 3 feet and 8 inches into feet only, we know,
So, 3 feet 8 inches = feet
It means length of each section = feet
Carpenter needs to cut 4 sections, so length of 4 sections will be =
2/3 feet means 8 inches so she needs board 14 feet 8 inches
Board is only sold by the feet only so, she has to puchase 15 feet board. : Answer
Hope it will help :)
Answer
-8 r > 0
Step-by-step explanation:
you know that r is less than or equal to -8, so you write that, and then you know that r is also greater than 0, so then you add that to it, and then you have the answer. r will be in the middle because it is the range of what are can be.
