Because you can only add and subtract radicals with the same radicand,
you get 2

that is the simplified answer but if you want it in decimals, 2.022 is what you get.
4 / 5 - 2 / 3 ( taking LCM on bottom )
= ( 12 - 10 ) / 15
= 2 / 15 Ans
<span>To find this answer, use multiples. For every 5000 feet ascended, deduct 18 degrees. For 20,000 feet, which is (4 * 5000), use (4 * -18). In this case, the answer is -72 degrees F, so the integer described would be -72.</span>
C. translated down 2 units
---The "-2" located on the outside of f(x) tells us that the y-values are being changed. With that, the graph can be moved up or down. The presence of the negative/subtraction sign tells us that the graph is moved down.
D. translated right 4 units
---The "-4" located with the x in f(x) tells us that the x-values are being changed. The only tricky thing about this is that the direction of the movement is actually the opposite of the sign. So with the negative/subtraction sign, the graph is moved to the right instead of the left.
Hope this helps!
2800 ÷ 400
Cross out 2 zeros from both numbers, then you have 28 ÷ 4 = 7
