Answer:

A) y = 4/3 x - 1/3

Step-by-step explanation:

(4,5) and (-2,-3)

Slope = (5 + 3)/(4 + 2)

= 8/6

= 4/3

Equation

y + 3 = 4/3(x + 2)

y + 3 = 4/3 x + 8/3

y = 4/3 x + 8/3 - 9/3

y = 4/3 x - 1/3

Answer:

y = 4/3 x - 1/3

Verdich [7]

Step-by-step explanation:

5(tanx)^2 -2 +tanx=0

let tanx=y

5y^2 + y-2=0

y=0.5403 or y= -0.7403

tanx=0.5403

x=arctan(0.5403)

x=28.38°

tanx=-0.7403

x=arctan(-0.7403)

x=143.49°

Some questions have the form y = kx, where k is a number. Drag each question to the correct category below. ( X = y/2 ),( y = .1

fomenos

Answer:

Has the form y = kx

( y = 0.11x)

(y = 0.04x)

Can be put into form y = kx

(z/x = 9)

Other

(5 = xy)

( x = y/2)

Step-by-step explanation:

y = kx

( y = 0.11x)

(y = 0.04x)

kx = y

(z/x = 9)

-----------

( x = y/2 )

( x - 5 = y)

(5 = xy)

Answer:

Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644

Step-by-step explanation:

The cost equation is given as:

$C=0.04x^2-5x+800$

This is a quadratic equation in general form, which is:

$y=ax^2+bx+c$

Matching, we can say:

a = 0.04

b = -5

c = 800

The minimum occurs at $x=-\frac{b}{2a}$

and the minimum value would be to place that "x" value into the equation.

First, we find the minimum using values of a and b:

$x=-\frac{b}{2a}=-\frac{-5}{2(0.04)}=\frac{5}{0.08}=62.5$

Plugging this into original, we get:

$C=0.04x^2-5x+800\\C=0.04(62.5)^2-5(62.5)+800\\C=643.75$

Rounding off to nearest whole number, we can say:

Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644
