5x + 2y = 2120

x + y = 574

2y = 2120 - 5x

2y = 1148 - 2x

1148 - 2x = 2120 - 5x

-972 = -3x

x = 324

574 - 324 = y

y = 250

Find the product <br><br>(x^2+3x+1)(x^2+x+2)​
natulia [17]

Answer:

x^4 + 4x^3 + 6x^2 + 7x +2

Step-by-step explanation:

x^2 x x^2 = x^4

x^2 x x = x^3

x^2 x 2 = 2x^2

3x x x^2 = 3x^3

3x x x = 3x^2

3x x 2 = 6x

1 x x^2 = x^2

1 x x = x

1 x 2= 2

x^4 + 4x^3 + 6x^2 + 7x +2

If 5x-26=x+50, then the value of x is
horsena [70]
Let's work this problem out!

First: 5(x) - 26 - x + 50 = ? 

Second: 4(x) - 76 = ? 

Third: 4 = ? 
          ↑
(Solve Step 3) 

Fourth: x - 19 = 0 
                   ↑
(Add the number 19 to each of your sides for Step 4)

Finally we get to your answer

19 + 0 = 19 ; 19 - 19 = 0

So, therefore the value of "x" is 19 

x = 19

Select the descriptions that are true of the equation y - 6= - 3(x+2). Select all that apply.
Lapatulllka [165]

The point-slope form:

y-y_1=m(x-x_1)

We have

y-6=-3(x+2)\to y-6=-3(x-(-2))

Therefore

<h3>slope = -3 and the point (-2, 6)</h3>

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

<h3>y + 2 = 2(x - 1)</h3>

2x - y = 4    <em>it's standard form Ax + By = C</em>

y = 2x - 4     <em>it's slope-intercept form y = mx + b</em>

y - x = 4 →<em> </em>x - y = -4  <em>t's standard form Ax + By = C</em>
