Step-by-step explanation:

<em>Given</em><em> </em><em>that</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>-2</em><em>.</em><em>5</em>

<em>To</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>+</em><em>13</em>

<em>Ob</em><em> </em><em>substituting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>given equation</em><em> </em>

<em>we</em><em> </em><em>get</em><em> </em>

<em>=</em><em> </em><em>-2</em><em>.</em><em>5</em><em>+</em><em>13</em>

<em>=</em><em> </em><em>13</em><em> </em><em>-</em><em> </em><em>2</em><em>.</em><em>5</em><em> </em><em> </em><em> </em><em> </em><em>(</em><em>we</em><em> </em><em>can</em><em> </em><em>also</em><em> </em><em>write</em><em> </em><em>like</em><em> </em><em>this</em><em>)</em>

<em>=</em><em> </em><em>10</em><em>.</em><em>5</em>

<em>Therefore</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>+</em><em>13</em><em> </em><em>is</em><em> </em><em>10</em><em>.</em><em>5</em>

Guide<br> What are the zeros of the function f, where f(x) = 6x2 - 9x – 6?
dolphi86 [110]

Answer:

Step-by-step explanation:

Use the Pythagorean Theorem to find the zeros of 6x² - 9x - 6.

x = [9±√(9²-4(6)(-6))]/[2(6)] = [9±√225]/12 = [9±15]/12 = 2, -½

What is the solution to the given system of equations. y = 4x - 3<br> y = -X- 13
san4es73 [151]
Y = 4x - 3
y = -x - 13
Since both equations equal y, we will just substitute both equations to equal each other.
4x - 3 = -x - 13
+x on both sides
5x - 3 = -13
+3 on both sides
5x = -10
/5 on both sides
x = -2

Substitute x = -2 into one of the equations.
y = -x - 13
y = -(-2) - 13
y = 2 - 13
y = -11

To check answer, plug in both x and y values into one of the equations.
y = -x -13
-11 = -(-2) - 13
-11 = 2 - 13
-11 = -11

Answer:
x = -2
y = -11

What can you factor out of 5x^2+20x
jonny [76]
5x(x+4)

Step by step

5x^2 = 5x(x) because it’s the largest you can divide by
20x =4 because 5x times by 4 = 20x
Which means 5x^2+20x = 5x^2+20x= 5x(x+4)
