First move the 13 to the left by subtracting 13 from both sides and setting the 'now expression' equal to zero

p² - 12p - 13

Do the opposite of FOIL (for you are trying to find the numbers being FOILed)

p² - 12p - 13

Find the multiplies of the outside numbers/variables, that, when added (or subtracted, will give you the inside expression

p² - 12p - 13
p -13
p 1

(p - 13)(p + 1)

Set these two expressions equal to zero

p - 13 = 0
p - 13 (+13) = 0 (+13)
p = 13

p + 1 = 0
p + 1 (-1) = 0 (-1)
p = -1

Your answers: p = -1, 13

hope this helps

What is the solution to the system of equations below? y = one-half x minus 4 and y = negative 2 x minus 9 (–2, –5) (–2, –3) (2,

Maurinko [17]

We have been given a system of equations $y=\frac{1}{2}x-4$ and $y=-2x-9$ . We are asked to find the solution of our given system of equations.

To solve our system of equations, we will equate both equations as:

$\frac{1}{2}x-4=-2x-9$

$\frac{1}{2}x-4+4=-2x-9+4$

$\frac{1}{2}x=-2x-5$

$\frac{1}{2}x+2x=-2x+2x-5$

$\frac{1}{2}x+\frac{4}{2}x=-5$

$\frac{1+4}{2}x=-5$

$\frac{5}{2}x=-5$

$\frac{2}{5}\cdot \frac{5}{2}x=-5\cdot \frac{2}{5}$

$x=-2$

Upon substituting $x=-2$ in equation $y=-2x-9$ , we will get:

$y=-2(-2)-9$

$y=4-9$

$y=-5$

Therefore, the solution of our given system of equations would be $(-2,-5)$ and option A is the correct choice.

What is the negative solution to this equation? 4x^2+12x=135

Scrat [10]

Answer:

$-\frac{15}{2}$

Step-by-step explanation:

$\mathrm{Subtract\:}135\mathrm{\:from\:both\:sides}$

$4x^2+12x-135=135-135$

$\mathrm{Simplify}$

$4x^2+12x-135=0$

$x1, 2=−b±√b2−4ac2a For a=4, b=12, c=−135x1, 2=−12±√122−4· 4(−135)2· 4$

Write the equation of a line with the slope of 2, which contains the point

Crazy boy [7]

Answer:

y=2x-16

Step-by-step explanation:

So since we have a point and the slope, we can use the point-slope equation to find our equation of a line

y - y₁ = m(x - x₁)

Here our (x₁, y₁) point is (4, -8) and our m is 2

Plugging in these values to our equation gives us:

y - (-8) = 2(x - (4)) → distributing the negative to the -8 gives y + 8 = 2(x - 4) → distributing the 2 to the (x - 4) gives y + 8 = 2x - 8 → and finally subtracting the 8 from both sides gives our equation of a line y = 2x - 16

What would the y intercept of a line B if it is perpendicular to 1/3x+2

Thepotemich [5.8K]

Hey!

Hope this Helps....

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To find the perpendicular line, of any given line goes like this...

if m (slope) of this given line is 1/3, than we know that the perpendicular line has a slope of -3

Now, to find the equation of this line, we need to find out where it crosses the y-axis... And because we are not given any specific points on where the perpendicular line crosses. We see that the point it pass the y-axis is 0

So... the perpendicular line of 1/3x+2 is -3x
