Answer:
24y^15 - 24y^10 + 7
Step-by-step explanation:
f(2y^5)
= 3(2y^5)^3 - 6(2y^5)^2 +7
= 3(8y^15) - 6(4y^10) + 7
= 24y^15 - 24y^10 + 7
Answer:
It is x2 -4 because it correct
Answer:
When the range is wide
Step-by-step explanation:
The denominator of a fraction is 1 more than 3 times the numerator. If the denominator is doubled and the numerator is increased by 2, the value of the resulting fraction is 1/4. Find the original fraction.
17= -13 -8x
+13
30=-8x
devide both sides by -8
-3.75 = x
x= -3.75
