Y=3-4/3x
y-intercept is 3

disa [49]2 years ago

5 0

Answer:

y - intercept: (0,3)

slope: -4/3

Step-by-step explanation:

4x +3y = 9

3y = -4x + 9

y = -4/3x + 3

to find the y - intercept you make x = 0, so...

y = -4/3(0) + 3

y = 3

therefore y - intercept is (0,3)

to find the slope you look at your linear equation and see what number is in front of the x

so in this case -4/3 is the slope, because that's what's in front of the x

A long-distance telephone company charges a rate of cents per minute or a -cent minimum charge per completed call, whichever

LiRa [457]

Answer: 50 cents

Step-by-step explanation:

Company charges 8 cents per call and the call in question is 3 minutes. Cost is;

= 3 * 8

= 24 cents

Company however stipulates that a call is 8 cents per minute or a 50-cent minimum charge per completed call, whichever is greater.

<em>50 cents is greater than the per minute total charge of 24 cents so the cost will be 50 cents.</em>

PLEASE HELP I HAVE 10 MINUTES LEFT

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
