Answer: Irrational</h3>
We cannot write sqrt(12) as a fraction of two whole numbers
Note how sqrt(12) = 3.464 and the decimal portion goes on forever without any known pattern (and it doesnt repeat either).
Compare this to something like sqrt(16) = 4 which can be written as a fraction 4/1, so sqrt(16) is rational
Answer: ![y=2.5x+2.5](https://tex.z-dn.net/?f=y%3D2.5x%2B2.5)
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where "m" is the slope and "b" is the y-intercept.
Since we know that the line passes through the point (2,7.5) and (-1,0), we can find the slope with this formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Substituting values, we get:
![m=\frac{0-7.5}{-1-2}\\\\m=2.5](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B0-7.5%7D%7B-1-2%7D%5C%5C%5C%5Cm%3D2.5)
In order to find the y-intercept, we can substitute the slope and the point (-1,0) into
and then solve fo "b":
![0=(2.5)(-1)+b\\\\0=-2.5+b\\\\b=2.5](https://tex.z-dn.net/?f=0%3D%282.5%29%28-1%29%2Bb%5C%5C%5C%5C0%3D-2.5%2Bb%5C%5C%5C%5Cb%3D2.5)
Then, the equation of this line in Slope-Intercept form is:
![y=2.5x+2.5](https://tex.z-dn.net/?f=y%3D2.5x%2B2.5)
Answer: -2.85
Step-by-step explanation:
To convert 22/20 into a decimal, we must multiply it by 5 to get a denominator of 100.
5(22/20)= 110/100= 1.10
So now lets solve the equation.
-1.75-1.10 = -2.85
