{16y}^{2}  + 40y + 25

Step-by-step explanation:

(4y−5)^2+80y

Use binomial theorem (a−b)^2=a^2−2ab+b^2 to expand (4y−5)^2.

16y^2−40y+25+80y

Combine −40y and 80y to get 40y.

16y^2+40y+25

vovangra [49]

Answer:

The given inequality is

\frac{2y}{3}  - 9 < y + 1

Let y be a Real number such that 9 less than two third of that number is less than  one added to that number.

We can find solution of the inequality also

1. keeping variable on one side and constant on another side, which gives

→y - \frac{2y}{3} > -9 -1

→\frac{y}{3} > -10\\\\y> -30

(a) State whether each of the following is a function. (6, 2), (8,2), (6,3), (12,3) Yes / No ​
Sloan [31]

Answer:

Not a function.

Step-by-step explanation:

The definition of a function specifies that no value of <em>x</em> can be paired with two or more different values of <em>y</em>.  

In the given relation:  {(6, 2), (8, 2), (6, 3), (12, 3)},

The input value of x = 6 has two corresponding output values (y-coordinates): 2 and 3.

Therefore, the given relation is not a function.
