2x+7+12y+1=180 and
2x+7=3x-7

x+6y=86 and
x=14

so x+6y=86 is 14+6y=86

6y=72

y=12

answer: x=14 and y=12

What are the zeros of the function f(x)=x^2-2x-15?
valkas [14]
To find the zeros of this function, we must first set the entire function equal to 0

f(x) = x² - 2x - 15 = 0

Since this is a quadratic function, we must use the quadratic formula, which is:

\frac{-b +/-  \sqrt{b^{2} - 4(a)(c) } }{2a}

Let's assign a, b, and c using our first function
x² means a = 1 (because it could be written as 1x²)
-2x means b = -2
-15 means c = -15

Now let's plug those in:

\frac{-(-2) +/- \sqrt{(-2)^{2} - 4(1)(-15) } }{2(1)}

which simplifies to:

\frac{2 +/- \sqrt{(4 + 60} }{2}

Simplified further:

\frac{2 +/- \sqrt{(64} }{2}
\frac{2 +/- 8 }{2}
And divide it by the 2 on the bottom gives us:

2 +/- 4

2+4 = 6
2-4 = -2

So the zeros of this function are -2 and 6

777dan777 [17]
Answer:

<span>⇒x=9</span> (positive solution)

Explanation:

<span><span>x2</span>−36=5x</span>

<span>→<span>x2</span>−36−5x=0</span>

Factor the expression:

We get:

<span><span>(x−9)</span><span>(x+4)</span>=0</span>

First solution:

<span>⇒<span>(x−9)</span>=<span>0<span>x+4</span></span></span>

<span>⇒<span>(x−9)</span>=0</span>

<span>⇒x=<span>9</span></span>
