What is 2x+8y=12 in slope intercept form
as well as x-2y=0 in slope intercept form

Answers

Answer 1

Answer: $the \ slope \ intercept \ form \ is : \n \n y= mx +b \n \n 2x+8y=12 \ \ |-2x \n \n8y=-2x+12\ \ /:8\n \ny=-(2)/(8)x+(12)/(8)$

$y=-(1)/(4)x+(3)/(4)\n \n m=-(1)/(4)$

$x-2y=0 \ \ | -x \n \n-2y=-x \ \ /:(-2)\n \ny=(1)/(2)x \n \n m= (1)/(2)$

Answer 2

Answer: 2x+8y=12
-2x -2x
8y/8=(-2x+12)/8
y=-0.25+1.5

x-2y=0
-x -x
-2y/-2=-x/-2
y=0.5x

Question 4 pleaseeeeeee

Answers

Answer:

Step-by-step explanation:

Unit rate means one quantity in terms of another unit quantity. In the answer choices, we see that the denominator is always in terms of UNIT LITERS (1 L), so that means, we have to find gallons in terms of UNIT LITERS.

It means, we have to divide gallons by liters to get in terms of unitary liters.

Let's check the first line:

19.5/75 = 0.26 Gallons / 1 Liter

Now, checking 2nd:

39/150 = 0.26 Gallons / 1 Liter

So, yes, they are the same and other 2 lines would be the same as well. The unit rate is:

0.26 gal/1L

That's answer choice B

a farm raises cows and chickens. the farmer has a total of 42 animals. one day he counts the legs of all animals of his animals and realizes he has a total of 114. how many cows does the farmer have? how many chickens?

Answers

Let's call cows x, and chickens as y.

Cows have 4 legs
Chickens have 2 legs.

Let's make two equations from the information they gave us!

x + y = 42
4x + 2y = 114

Now, let's multiply the first equation by 4.

4x + 4y = 168
4x + 2y = 114

Now, subtract the second equation from the first one.

4x - 4x + 4y - 2y = 168 - 114

4y - 2y = 168 - 114

2y = 54

y = 27

Now, plug y = 27 into either equation and solve for x.

x + y = 42

x + 27 = 42

x = 42 - 27

x = 15

There are 15 cows and 27 chickens.

Alex opens a 1-pint container of orange butter. He spreads 1/16of the butter on his bread. The he divides the rest of the butter into 3/4-pint containers.how many 3/4-pint containers is he able to fill?

Answers

The first thing to do is to make the denominators of the fractions the same:
16 / 4 = 4. 4 X 3 = 12.
12/16.

16 / 1 = 16. 16 X 1 = 16
16/16

Now you write this out as a fraction equation:
(16/16 - 1/16) / 12/16
15/16 / 12/16

Since all you need to know is the whole number, you can easily tell that 15 / 12 is less than 2.

Therefore, Alex is able to fill one 3/4-point containers with orange butter.

One pint can fill only a single 3/4-pint container, even before anybody takes away any of the full pint.

I need help on my math homework.A hairdresser is considering ordering a certain shampoo. Company A charges $4 per 8-oz bottle plus a $10 handling fee per order. Company B charges $3 per 8-oz bottle plus a $25 handling fee per order. How many bottles must the hair dresser buy to justify using Company B? (Answer in a complete sentence.)

I don't know what justify using company B means. Can someone help me?

Answers

hi tissuebox,

let x= the number of bottles the customers buys

first, lets consider how many bottles the customer must buy for the price to be the same no matter which company.

4x+10=3x+25
.
.
.
x=15, so at 15 bottles, the cost is the same for either company. At this point you look at x=16, one bottle higher, to compare costs, seeing that for company A this is $74 while for company B this is $73, so at 16 bottles company B is cheaper
