2x - 5y = 9
2x -9 = 5y
(2x -9) /5 = y

x= -1
(2(-1) -9)/5 =y
(-2 -9) / 5 = y
-11/5 = y

x=0
(0-9)/5 = y
-9/5 = y

x=1
(2(1) - 9) /5 = y
-7/5 = y

The sum of two trinomials is 6x2 − 5x + 4. If one of the trinomials is 4x2 + 3x − 2, then what is the other trinomial?

Vadim26 [7]

Subtract the known trinomial from the total sum:

6x2 - 5x + 4 - 4x2 + 3x - 2 = 2X^2 -8x +6
I hope this helps :)

Solve. −35x+15>720 Drag and drop a number or symbol into each box to show the solution.

Answer:

The solution of the inequality - 35x + 15 > 720 is $x$

Step-by-step explanation:

Consider the given inequality

- 35x + 15 > 720

Subtract both side by 15 , we get

- 35x + 15 - 15 > 720 - 15

- 35x > 705

Multiply both sides by -1 (Reverse the inequality )

(-35x)(-1) < 705 (-1)

35x < -705

Now, divide both side by 35

$\frac{35x}{35}=\frac{-705}{35}$

$\Rightarrow x=\frac{-141}{7}$

Thus, the solution of the inequality - 35x + 15 > 720 is $x$
