When you solve fractions and you end up having an improper fraction so you simplify. So you get a mixed fraction. So to convert an improper fraction to the mixed one you simply divide the numerator by denominator. simple.
Answer:
2(9x^2-4)
Step-by-step explanation:
Answer:
The correct answer is: Option D: 8
Step-by-step explanation:
Given that she spent $208 on the sewing machines
And
the equation for profits to break even is:
208 + 10x = 36x
In order to find the number of purses to break even, we have to find the value of x
So,
![208+10x=36x](https://tex.z-dn.net/?f=208%2B10x%3D36x)
Subtracting 10x from both sides
![208+10x-10x = 36x-10x\\208 = 26x](https://tex.z-dn.net/?f=208%2B10x-10x%20%3D%2036x-10x%5C%5C208%20%3D%2026x)
Dividing both sides by 26
![\frac{208}{26} = \frac{26x}{26}\\x = 8](https://tex.z-dn.net/?f=%5Cfrac%7B208%7D%7B26%7D%20%3D%20%5Cfrac%7B26x%7D%7B26%7D%5C%5Cx%20%3D%208)
The number of purses is 8
Hence,
The correct answer is: Option D: 8
Answer:
a. 3/2
b. 6/4 idk if you need to simplify, but if so it would be 3/2
c. y = 3/2x
Step-by-step explanation:
a: to find the rate of change of points A and B, you just use a formula (i forgot what it's called but it looks like this) y2-y2/x2-x1
3/2-0/0= 3/2
so the rate of change = 3/2
b: again, using the same formula, y2-y2/x2-x1, but using points C and D
12/8-6/4=6/4 simplified to 3/2
c: since the line goes through the origin, (0,0), then there isn't a y-intercept
making the equation: y = 3/2x
