What 2 numbers add up to get 17 and multiply to get -308??

Rufina [12.5K]

A) x + y = 17
B) x * y = -308

B) y = -308 / x Substituting this into A)
A) x -308 / x = 17
A) x^2 -308 = 17x
A) x^2 -17x -308 = 0
x = 28
y = -11

Indicate the equation of the given line in standard form. The line through (2, -1) and parallel to a line with slope of 3/4

Ket [755]

Well, for a line with a slope of 3/4, any other parallel line to it, will also have the same slope of 3/4

so if the line through (2, -1) is parallel to it, it has a slope of 3/4 as well

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ 2}}\quad ,&{{ -1}})\quad 

\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{3}{4}
\\\\\\
% point-slope intercept
y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad 
\begin{array}{llll}
\textit{plug in the values for }
\begin{cases}
y_1=-1\\
x_1=2\\
m=\frac{3}{4}
\end{cases}\\
\textit{and move everything}\\
\textit{to the left-hand-side}
\end{array}\\

\left. \qquad \right. \uparrow\\
\textit{point-slope form}$

Trigonometry question! find the vaule of x. round to the nearest tenth!

atroni [7]

Answer:

<h2>x = 88.2</h2>

Step-by-step explanation:

Look at the picture.

Use tangent:

$tangent=\dfrac{opposite}{adjacent}$

We have a measure of the angle and length of the adjacent:

$\alpha=10^o,\ adjacent=500$

$\tan10^o\approx0.17633$

Substitute:

$\dfrac{x}{500}=0.17633$ <em>multiply both sides by 500</em>

$x=88.165\to x=88.2$

What is the standard form and the factored form

Feliz [49]

Answer:

See below

Step-by-step explanation:

<u>The factored form, use variables/numbers outside the square:</u>

(x + 6)(x - 4)

<u>The standard form, use variables/numbers inside the square:</u>

x² + 6x - 4x - 24 = x² + 2x - 24
