-9/15y+3/21=5/15y-14/21

Move 5/15y to the other side. Sign changes from +5/15y to -5/15y

-9/15y-5/15y+3/21=5/15y-5/15y-14/21

-14/15y+3/21=-14/21

Move 3/21 to the other side. Sign changes from +3/21 to -3/21.

-14/15y+3/21-3/21=-14/21-3/21

-14/15y=-14/21-3/21

-14/21-3/21=-17/21

-14/15y=-17/21

Multiply both sides by -15/14

-14/15y(-15/14)

Cross out 15 and 15, divide by 15 then becomes 1

Cross out 14 and 14, divide by 14 then becomes 1

1*1*y=y

-17/21*-15/14

Cross out 15 and 21 , divide by 3. 15/3=2, 21/3=7

17/7*5/14=85/98

Answer: c. y=85/98

Hey there!

3^15/ 3^3

3^15

= 3*3*3*3*3*3*3*3*3*3*3*3*3*3*3

= 9*9*9*9*9*9*9*3

= 81*81*81*27

= 6,561 * 2,187

= 14,348,907

= 14,348,907/3^3

3^3

= 3*3*3

= 9*3

= 27

14,348,907/27

= 531,441

15 - 3 = 12

= 3^12

Because

3^12

= 3*3*3*3*3*3*3*3*3*3*3*3

= 9*9*9*9*9*9

= 81*81*81

= 6,561*81

= 531,441

531,441 ≈ 3^12

Therefore, your answer should be: 3^12

Good luck on your assignment and enjoy your day!

The graph of a polynomial function f is shown
SVETLANKA909090 [29]

Answer:

The degree of the polynomial is even because it is a 4th degree polynomial. 4 is even, so the graph will behave roughly like a quadratic; namely, its graph will either be up on both ends or else be down on both ends.

The y-intercept is the constant term. The constant term is -4 because it is the only number on the y-axis.

The question that I'm having issues with is, "The complement of an angle, A, in degrees, is equal to one-sixth of the supplement
dolphi86 [110]
'Complement' = difference between an angle an 90 degrees.

'Supplement' = difference between an angle and 180 degrees.

Complement of A = 90 - A

Supplement of A = 180 - A

The problem says that the complement is 1/6 of the supplement, right ?

So    <u>  90 - A = (1/6) x (180 - A)</u>

Multiply each side of this equation by 6 :

540 - 6 A = 180 - A

Subtract 180 from each side:

360 - 6 A = - A

Add 6A to each side :

360 = 5 A

Divide each side by 5 :

<u>A = 72°</u>
