Answer:
(B)![\frac{10}{10}-\frac{7}{10}=\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B10%7D-%5Cfrac%7B7%7D%7B10%7D%3D%5Cfrac%7B3%7D%7B10%7D)
Step-by-step explanation:
The question is Incomplete. Find the complete question in the attachment.
Number of muffins made by Franco =12
Number of Badly Burnt Muffins =2
Number of non burned muffins =12-2=10
Franco served ![\frac{7}{10} $ of the non burned muffins = $ \frac{7}{10}*10=7$ muffins](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B10%7D%20%24%20of%20the%20non%20burned%20muffins%20%3D%20%24%20%5Cfrac%7B7%7D%7B10%7D%2A10%3D7%24%20muffins)
Therefore, the number of non burned muffins that remains =10-7 =3
We can then say the fraction of the non-burned muffins that remains![=\frac{3}{10}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3%7D%7B10%7D)
Therefore, the correct equation is in Option B:
![\frac{10}{10}-\frac{7}{10}=\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B10%7D-%5Cfrac%7B7%7D%7B10%7D%3D%5Cfrac%7B3%7D%7B10%7D)
Answer: Choice A and choice C
The fractional exponent of 1/2 means that the root index is 2, which is a square root. So (13+8)^(1/2) becomes sqrt(13+8) = sqrt(21)
"sqrt" is a common abbreviation of "square root"
Answer:
y = -x +5
Step-by-step explanation:
The 2-point form of the equation of a line is useful for this.
y = (y2 -y1)/(x2 -x1)(x -x1) + y1 . . . 2-point form of equation for a line
y = (-2 -6)/(7 -(-1))/(x -(-1)) +6 . . . . substitute the give points
y = -8/8(x +1) +6 . . . . . . . . . . . . . . simplify a bit; next, simplify more
y = -x +5
Cross multiply so you have kx9 = 9k and 3x3 = 9 so 9k = 9, now you divide by 9 and you get k=1
