0.4 has 4 tenths
Look at 0.4 as 0.40
Divide the 40 by 10 and get 4
-Hope this helped!
Roots test tells us to take the factors of the 20 divided by the factors of the coefficient of the the first.
factors of 20 are 1,2,4,5,10,20
factors of 1 are 1
so plus or minus 1/1, 2/1, 4/1, 5/1, 10/1, 20/1 are all possible rational zeros
Given:
Equation of line 
.
To find:
The equation of line that goes through the point ( − 21 , 2 ) and is perpendicular to the given line.
Solution:
The given equation of line can be written as
Slope of line is
Product of slopes of two perpendicular lines is -1. So, slope of perpendicular line is
![[\because m_1=\dfrac{7}{4}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20m_1%3D%5Cdfrac%7B7%7D%7B4%7D%5D)
Now, the slope of perpendicular line is 
and it goes through (-21,2). So, the equation of line is
Therefore, the required equation in slope intercept form is .
Answer:
im quite confused with the way its been layed out
cant tell if ur multiplying of its a X
Step-by-step explanation:
(2^8 times 5 ^-8 times 1) ^-2x times 5^-2 over 2^3 times 4 times 2 ^28
(2^-16x times 5^10x times 5^-2 over 8 times 4 times 2^28
2^16=28 times 5 ^10x
------------------------------- over
