Answer:

x - 3

Step-by-step explanation:

\frac{2{x}^{2} - 5x - 3}{2x + 1} = \frac{[x - 3][2x + 1]}{2x + 1} = x - 3

This is much faster than doing long-polynomial division, which we could have done, since the divisor is not in the form of <em>x</em><em> </em><em>-</em><em> </em><em>c,</em><em> </em>where<em> </em><em>−</em><em>c</em><em> </em>gives gives the OPPOSITE TERMS OF WHAT THEY REALLY ARE.

I am joyous to assist you anytime.

Please help with Algebra
mina [271]

Answer:

C) 6

Step-by-step explanation:

I converted the equation into slope-intercept form and then identified the y-intercept.

4x+2y=12\\\\4x-4x+2y=12-4x\\\\2y=12-4x\\\\\frac{2y=12-4x}{2}\\\\ y=6-2x\\\\y=-2x+6\\\\y=-2x+\boxed{6}

C should be the correct answer.

Hope this helps.

Solve the system of equations and choose the correct ordered pair. 3y=4x+7 and 5y=4x+25​
Luba_88 [7]

Answer:

(5,9)

Step-by-step explanation:

3y=4x+7

5y=4x+25​

Subtract the two equations to eliminate x

5y=4x+25

-( ​3y=4x+7)

------------------

2y = 0x +18

Divide by 2

2y/2 = 18/2

y =9

Now find x

3y = 4x+7

3*9 = 4x+7

27 = 4x+7

Subtract 7

20 = 4x

Divide 4

20/4 = 4x/4

5 =x

(5,9)
