2y=-6x+8
First, the slope of any equation, is always the coefficient with the variable "x".
So, the slope for this line, is -6x.
To get rid of the coefficient with y, we need to divide 2, from both sides of the equal sign.
<u>2y=-6x+8</u>
2
y=-3+4
Now that we have our new equation, we can see that the slope of our line has also changed, from -6x to-3x. Because -6÷2=-3.
And to find the perpendicular slope, you change the reciprocal of the slope so from -3 to 1/-3 and then you change the sign of the slope so from 1/-3 to 1/3. That is your final answer.
The answer is 2) 1/3.
Answer:
Interest = Rs 2000
Amount = Rs 7000
Step-by-step explanation:
Amount = Principal + Interest
Given
Principal = Rs 5000
Interest= PRT/100
Interest = 5000*8*5/100
Interest = 50*40
Interest = Rs 2000
Amount after 5years = 5000 + 2000
Amount after 5years = Rs 7000
Answer:
Step-by-step explanation:
(-2, 0), (1, 2) = (2 - 0)/(1+2)= 2/3

Answer:a. 0.13% b. 2.28%
Step-by-step explanation:
Let x denotes the useful life of batteries.
Given: months,
Since X is normally distributed.
The probability that batteries with a useful life of less than 38 months
The percent of batteries with a useful life of less than 38 months =0.13%
The probability that batteries will last longer than 68 months
The percent of batteries that will last longer than 68 months =2.28%
