Answer:
![\frac{1+\sqrt{13} }{4}, \frac{1-\sqrt{13} }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%2B%5Csqrt%7B13%7D%20%7D%7B4%7D%2C%20%5Cfrac%7B1-%5Csqrt%7B13%7D%20%7D%7B4%7D)
Step-by-step explanation:
First, make them on one side of the formula in the form of
which is ![4x^{2} -2x-3=0](https://tex.z-dn.net/?f=4x%5E%7B2%7D%20-2x-3%3D0)
Next, insert the corresponding number in the quadratic formula,
, and the answer can be calculated.
First, you need convert the decimals into fraction
0.26 = 26/100 = 13/50
The next step would be drawing 50 small boxes on a piece of paper. Make it colorless.
The final stap would be giving 13 out of those 50 boxes with different color (such as black), and you're done
False, they have a different slope and y intercept
8/ (1 1/2) = 36/x....8 muffins to 1 1/2 tsp = 36 ( 3 doz) muffins to x tsp
this is a proportion, so we cross multiply
(8)(x) = (1 1/2)(36)
8x = 3/2 * 36
8x = 108/2
8x = 54
x = 54/8
x = 6 3/4 <=== 6 3/4 tsps are needed to make 3 doz muffins
