Alex777 [14]3 years ago
4 0

Answer:

72.1 and -48.1

Step-by-step explanation:

I set up the equations x + y = 24 and x*y=-3468. Then I substituted for y and used the quadratic formula to come to two numbers rounded to about 72.1 and -48.1. Hope that helps :)

If each case weighs 24 pounds, then 1p=24 pounds. so if we're trying to find a function of weight, p=24c.

Example: When you have 2 cases, you plug in a 2 for c

p=24c
p=24(2)
p=48

So if you have two cases, it will total 48 pounds,

So that is why the equation is p=24c. Hope this helps!

A movie theater complex gave a poll as viewers exited from two theaters showing the same film. They had a 20% response rate from
sp2606 [1]

Answer:

Let´s define the variables:

x = number of people in theater A

y = number of people in theater B

We know that a 20% (or 0.2 in decimal form) of the people in theater A answered the survey, then the number of people from theater A that answered the survey is: Na = 0.2*x

We know that a 30% (or 0.3 in decimal form) of the people in theater B answered the survey, then the number of people from theater B that answered the survey is: Nb = 0.3*y

There where 800 people in total (counting from the two theatres)

Then x + y = 800.

A) In this case we have:

Na = Nb

this means that:

0.2*x = 0.3*y

and we also have the equation:

x  + y = 800

To solve this, we need to isolate one variable in one of the equations, i will isolate x in the second equation:

x = 800 - y

And now we can replace this in the other equation to get:

0.2*(800 - y) = 0.3*y

We need to solve this for y:

160 - 0.2*y = 0.3*y

160 = 0.3*y + 0.2*y = 0.5*y

160/0.5 = y = 320

Then there where 320 people in theater B, and:

x + y = 800

x + 320 = 800

x = 800 - 320 = 480

There where 480 people in theather A.

B) Now we have:

x = 440

y = 360

then:

Na = 0.2*440 = 88

In theater A, 88 people answered the survey.

Nb = 0.3*360 = 108

In theater B, 108 people answered the survey.

In total, 88 + 108 = 196 people answered the survey.

If h(x) = 6 – x, what is the value of (h circle h) (10)?<br> –4<br> –2<br> 10<br> 16
Ganezh [65]

Answer:

10

Step-by-step explanation:

Here, we want to find the value of ;

h circle h(10)

This mean we are to put h in h, the find the function of 10

we have this as;

6-(6-x)

= 6-6 + x = x

Now, replace the x by 10; so we have h circle h(10)

What is the equation in slope-intercept form of the line that passes through the points (0, −4) and (2, 0)?
Nastasia [14]

Answer:

y = 2x -4

Step-by-step explanation:

Slope intercept form is  y = mx + b where <em>m </em>is the slope and <em>b </em>is the y-intercept.

Slope is \frac{rise}{run} or \frac{y_2 - y_1}{x_2-x_1} in this case = \frac{0 - (-4)}{2 - 0} = \frac{4}{2} = 2

Substitute one of the coordinates for x and y. I am going to use (0, -4) so:

-4 = 2(0) + b\\-4 = 0 + b\\-4 = b

since m = 2 and b = -4, we can conclude that the equation would be

y = 2x -4
