What is the equation if the line slope is 2/3 and the y-intercept is -3

lora16 [44]

<h2>The required equation of line is 2x - 3y - 9 = 0.</h2>

Step-by-step explanation:

Here, slope(m) = $\dfrac{2}{3}$ and y - intercept(c) = -3

To find, the required equation of line = ?

We know that,

The equation of a line with slope m and y-intercept c is given by

y = mx + c

∴ The required equation of line

y = $\dfrac{2}{3}$ x + (- 3)

⇒ y = $\dfrac{2}{3}$ x - 3

⇒ y + 3 = $\dfrac{2}{3}$ x

⇒ 3(y + 3) = 2x

⇒ 3y + 9 = 2x

⇒ 2x - 3y - 9 = 0

Thus, the required equation of line is 2x - 3y - 9 = 0.

The sum of two integers is -15. The product of the two integers is 54. What are those two integers a. -6 and -9 b. -6 and 9 c. 6

Bas_tet [7]

Let the two integers be x and y respectively

Hence;
$x + y = - 15 \\ \\ xy = 54$
From the first equation ;
$x = - 15- y$
Substitute into the third equation
$( - 15 - y)y = 54$
Open up the bracket
$- 15y - {y}^{2} = 54$
Take everything to the right hand side of the equation and you'll have a quadratic equation
$0 = 54 + 15y + {y}^{2}$
Solve the quadratic equation and you'll have two roots
$y= - 6 \: or \: y= -9$
Substitute for each value of y in the first equation
Therefore:
$x + ( - 6) = - 15 \: \\ or \\ \: x + ( - 9) = - 15$
$x - 6 = - 15 \\ or \\ x - 9 = - 15$
$x = - 15 + 6 \\ or \\ x = - 15 + 9$

$x = - 9 \: or \: x = - 6$
Therefore the answer is A

1. Find the vertices and locate the foci for the hyperbola whose equation is given.

Irina18 [472]

$\bf \cfrac{(x-{{ h}})^2}{{{ a}}^2}-\cfrac{(y-{{ k}})^2}{{{ b}}^2}=1
\qquad center\ ({{ h}},{{ k}})\qquad
 vertices\ ({{ h}}\pm a, {{ k}})\\\\
-----------------------------\\\\
\textit{now let's take a look at yours}
\\\\\\
49x2 - 16y2 = 784\implies \cfrac{49x^2}{784}-\cfrac{16y^2}{784}=1
\\\\\\
\cfrac{x^2}{16}-\cfrac{y^2}{49}=1\implies \cfrac{(x-0)^2}{4^2}-\cfrac{(y-0)^2}{7^2}=1
\\\\\\
recall\implies center\ ({{ h}},{{ k}})\qquad vertices\ ({{ h}}\pm a, {{ k}})
\\\\\\
$

$\bf \textit{now, for the foci, the foci are "c" distance from the center point}\\\\\
whereas\qquad c=\sqrt{a^2+b^2}\qquad \textit{ that is }\qquad h\pm \sqrt{a^2+b^2}$

notice your "a" and "b" components, to get the distance "c" from the center to either foci and the vertices, of course, are h + a, k and h - a, k

Myrna is driving at a constant rate in her car if she travels 135 miles in 3 hours how far would you travel in 8 hours

Romashka-Z-Leto [24]

360 miles in 8 hours you do 135 divided by 3 which gives you 45 then you do 45 times 8 giving you 360 I hope I helped and I’m sorry if just didn’t give you the correct answer I tried.
