First one:
Same denominator so ((9-7x)+(x-4))/(x+7)
Final answer:
(5-6x)/(x+7)
Second one:
Again same denominator so ((7x)-(11x))/(x-7)
Final answer:
(-4x)/(x-7)
Third one:
Same denominator again, ((9x)-(14x))/(x+9)
Final answer:
(-5x)/(x+9)
Fourth one:
Same denominator again, ((3x-4)-(x-9))/(x+6)
Final answer:
(2x+5)/(x+6)
Fifth one:
Different denominators here, so we have to make them them same. We do this by multiplying the first fraction by 3/3 to get (3x-9)/(2x), so ((3x-9)+(x-4))/(6x)
Final answer:
(4x-13)/(6x)
Sixth one:
This one is trickier, we have to multiply each by the others denominator, so ((11)*(x-2))/((x+9)*(x-2)) and ((3)*(x+9))/((x-2)*(x+9)) to get
(11x-22)/(x^2+7x-18) and (3x+27)/(x^2+7x-18)
Final answer:
(14x+5)/(x^2+7x-18)
Last one:
You can change the first fraction to 1/(x*(x-1)), then multiple the second fraction by (x-1)/(x-1) to get (x-1)/(x^2-x). Now add them.
Final answer:
(2-x)/(x^2-1)
Hope I helped :)
Answer:
Aaron travelled about 9 feet underwater
Step-by-step explanation:
We need to work with the information we are given in the question.
there are two stages of Aaron's travel. the first distance was in the air, and the second distance was in the water.
We are given both the total distance travelled and the distance travelled in the air.
To get the distance travelled in water, we subtract the distance travelled in the air from the total distance.
This will be 52 feet - 43 feet = 9 feet
Hence Aaron travelled about 9 feet underwater
Answer:
D
The range stays the same, but the domain changes
Step-by-step explanation:
Just took the test
86% because 0.086 equates ti 8.6%
0.1=1/10
0.01=1/100
0.001=1/1,000
