Answer:

(1, -5)

Step-by-step explanation:

Solve the system by setting the equations equal to each other, and solving for x:

-7x + 2 = 9x - 14

2 = 16x - 14

16 = 16x

1 = x

So, the x coordinate of the solution will be 1.

Plug in 1 as x into one of the equations, and solve for y

y = -7x + 2

y = -7(1) + 2

y = -7 + 2

y = -5

So, the y coordinate is -5.

The ordered pair solution is (1, -5)

Whats the answer of this problem <br> 8-1*0+2/2=??

Reptile [31]

If I'm doing this right, I'm pretty sure the answer would be 7, since 0 + 1 = 1, 8 - 1 = 7, and 7 x 1 = 7.

I hope this answer helped you! If you have any further questions or concerns, feel free to ask! :)

Of 10<br> Find the gradient of the line segment between the points (2,-2) and (0,-6).

Veseljchak [2.6K]

Answer:

<h3>The answer is 2</h3>

Step-by-step explanation:

The gradient of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

From the question we have

$m = \frac{ - 6 - - 2}{0 - 2} = \frac{ - 6 + 2}{ - 2} = \frac{ - 4}{ - 2} = 2 \\$

We have the final answer as

Hope this helps you

Simply the expression given below (3x^3+4x^2+4x-12)+(-5x^3+9x^2-9x+20)

Svet_ta [14]

Answer:

1. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)
