Answer:
a rational expression is an expression that has a RATIO in it
look at the word "RATIO"nal
a ratio is just a fraction...
so your question is "how to simplify fractions"
lots of approaches, this is one of them...
PRIME FACTOR the numerator and denominator
![\frac{90}{135}](https://tex.z-dn.net/?f=%5Cfrac%7B90%7D%7B135%7D)
90 = 2 * 3 * 3 * 5
135 = 3 * 3 * 3 * 5
= 2/3 (the two 3's cancel and the 5's cancel)

Answer:
y=50x+75
Step-by-step explanation:
In a linear equation, the parent form of the line is called y=mx+b where m is the slope of the graph and b is the y-intercept.
Slope: We can start from any point on the graph and we can see that with one x value, the y increases every 50. 50 would be the slope in this case. It is the change of y over the change of x (50/1)
Y-intercept: The graph starts off on the left hand at the number 75, which means the number to plug in is 75.

Since, function I stated that hours, h, pertains to the hours after 6am, and the question asks what is the temperature by 2pm, we will have h=8 because 2pm is 8 hours after 6am.
So,
![T(I(h))= \sqrt{5000( \frac{12(8)-(8)^2}{36} )} T(I(h))= \sqrt{5000( \frac{96-64}{36} )} T(I(h))= \sqrt{5000( \frac{32}{36} )} T(I(h))= \sqrt{ \frac{40000}{9} } T(I(h))=66.6666 or 67](https://tex.z-dn.net/?f=T%28I%28h%29%29%3D%20%5Csqrt%7B5000%28%20%5Cfrac%7B12%288%29-%288%29%5E2%7D%7B36%7D%20%29%7D%0A%0AT%28I%28h%29%29%3D%20%5Csqrt%7B5000%28%20%5Cfrac%7B96-64%7D%7B36%7D%20%29%7D%0A%0AT%28I%28h%29%29%3D%20%5Csqrt%7B5000%28%20%5Cfrac%7B32%7D%7B36%7D%20%29%7D%0A%0AT%28I%28h%29%29%3D%20%5Csqrt%7B%20%5Cfrac%7B40000%7D%7B9%7D%20%7D%0A%0AT%28I%28h%29%29%3D66.6666%20or%2067)
so the answer is (3), 67.
