Find the equation of the line passing through the point (4,−1) that is parallel to the line 2x−3y=9 Find the slope of the line 2

AnnZ [28]

Answer:

Step-by-step explanation:

2x - 3y = 9

-3y = -2x + 9

$y=\frac{-2}{-3}x + \frac{9}{-3}\\\\y=\frac{2}{3}x-3\\$

Parallel lines have same slope.So,

Slope m = 2/3

(4 , -1)

Equation: y - y1 = m(x - x1)

$y-[-1]=\frac{2}{3}(x - 4)\\\\y+1=\frac{2}{3}*x - \frac{2}{3}*4\\\\y+1=\frac{2}{3}x-\frac{8}{3}\\\\y=\frac{2}{3}x-\frac{8}{3}-1\\\\y=\frac{2}{3}x-\frac{8}{3}-\frac{3}{3}\\\\y=\frac{2}{3}x-\frac{11}{3}$

9. The theater club of a local high school is planning a production. The amount of time t needed to assemble the set is inversel

Vsevolod [243]

Answer:

The situation that represents this situation is:

$t = \frac{60}{n}$

Step-by-step explanation:

The amount of time t needed to assemble the set is inversely proportional to the number people n working.

This means that:

$t = \frac{k}{n}$

In which k is the constant of proportionality.

Twelve people can assemble the set in 5 hours.

This means that for $n = 12, t = 5$ . We use this to find k.

$t = \frac{k}{n}$

$5 = \frac{k}{12}$

$k = 12*5 = 60$

Write an equation to represent the situation.

$t = \frac{60}{n}$

Which equation represents a quadratic function with a leading coefficient of 2 and a constant term of –3?

Elan Coil [88]

Answer:

$2x^{2} +bx-3=0$

Step-by-step explanation:

General form. A quadratic function $f(x)$ is of the form $(ax^2+bx+c)$ where $a,b,c$ ∈ R or C and $a$ ≠ $0$ .

We obtain an equation when $f(x)=0$

⇒ $ax^{2} +bx+c=0$ is an quadratic equation.

Solution.

Given, $a=2,c=-3$ , but b is not given

Thus the quadratic function with leading coefficient $a=2$ and constant term $c=-3$ is given by

$f(x)=2x^{2} +bx-3$

∴ the required quadratic equation is

$2x^{2} +bx-3=0$
