Answer:
Fabric A= $7.5
Fabric B= $7.5
Step-by-step explanation:
Answer:
1
0.8
0.4
Step-by-step explanation:
y = 5x
Substituting '5':
5 = 5x
x = 5/5
x = 1
Substituting 4:
4 = 5x
x = 4/5
x = 0.8
Substituting 2:
2 = 5x
x = 2/5
x = 0.4
1/4 of the list price was off, so $90 was 3/4 of the list price. (1 -1/4= 3/4).
We have an equation: 90/? = (3/4)/1
Cross multiply:
3/4*? = 90*1
⇒ ?= 90*1/(3/4)= 90*1* (4/3)= 120.
The list price was $120.
Hope this helps~
Answer with Step-by-step explanation:
We are given function
![f(x)=x^2(x-2)(x-2)](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%28x-2%29%28x-2%29)
a.From given we can see that
When x approaches to infinity then y also approaches infinity.
When x approaches-infinity then y also approaches infinity.
b.To find the x-intercept
Substitute y=0
![x^2(x-2)(x+2)=0](https://tex.z-dn.net/?f=x%5E2%28x-2%29%28x%2B2%29%3D0)
![x=0](https://tex.z-dn.net/?f=x%3D0)
![x-2=0](https://tex.z-dn.net/?f=x-2%3D0)
x=2
![x+2=0](https://tex.z-dn.net/?f=x%2B2%3D0)
![x=-2](https://tex.z-dn.net/?f=x%3D-2)
x-intercept:(0,0),(2,0),(-2,0)
To find the y-intercept
Substitute x=0
![y=0](https://tex.z-dn.net/?f=y%3D0)
y-intercept:(0,0)
