The point-slope formula:
![y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29%5C%5C%5C%5Cm%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have (-2, 1) and (1, 7).
Substitute:
![m=\dfrac{7-1}{1-(-2)}=\dfrac{6}{3}=2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B7-1%7D%7B1-%28-2%29%7D%3D%5Cdfrac%7B6%7D%7B3%7D%3D2)
![y-1=2(x-(-2))\\\\y-1=2(x+2)](https://tex.z-dn.net/?f=y-1%3D2%28x-%28-2%29%29%5C%5C%5C%5Cy-1%3D2%28x%2B2%29)
Answer:
$150
Step-by-step explanation:
So, 60 dollars is 40% of the original price. So 30 dollars is 20% of the original price, and 150 dollars is 100% of the original price. So, the original value of the rice cooker is 150 dollars.
Answer:
6/6 or 1/1
Step-by-step explanation:
A standard number cube has 6 sides to it. Therefore there are 6 possibilities, as you can roll either a 1, 2, 3, 4, 5, or 6.
The question is asking what the probability is for not rolling a number more than 62. To reword the question to get rid of the confusing 'not', "What is the probability of rolling a number less than 62?"
All the possibilities on the dice are less than 62, therefore it is guaranteed you will not roll a number more than 62. The probability is 1, or written as a fraction 1/1, or 6/6, since 6 sides of the 6 sided cube are less than 62.
