# can y’all help me i keep posting this question and people keep guessing and i keep getting it wrong :/

y = 192.

Step-by-step explanation:

y = k/x^3  where k is the constant of variation.

When x = 1/5 y = 375, so:

375 = k / (1/5)^3

375 = k / 1 /125

125k = 375

k = 3.

So the equation of variation is y = 3/x^3

and when x = 1/4:

y = 3 / (1/4)^3

y = 3 * 64

= 192.

x=1

Step-by-step explanation:

You just have to go through it thoroughly. You are probably making a small mistake somewhere.

we know that

if two lines are perpendicular, then the product of their slopes is equal to minus one

so

The formula to calculate the slope between two points is equal to

we have

Step 1

Find the slope xz

Substitute in the slope's formula

Step 2

Find the slope yz

Substitute in the slope's formula

Step 3

Find the slope xy

Substitute in the slope's formula

Step 4

Verify if two of the slopes are perpendicular

Multiply  myz and mxy

-------> the lines segment yz and xy are perpendicular

therefore

the triangle XYZ is a right triangle

the answer in the attached figure

So the correct answer would be ( A ti no te gusta descansar.)

Explanation:

When you say "tu" in spanish is the same as saying ( Yours don't like to rest)

so you have to use "ti" ( You don't like to rest).

Remember that "Ti"   is a personal pronoun of second person singular and is always preceded by a preposition like : Esto es para ti, Vine porti, Lo recibió de ti.

Also it doesn't have an accent mark.

BTW the sentence can also go like this :  No te gusta descansar a ti ?  both you'll be right, unless they asked for something specific.

hope that helps :D

j > 5

j > 4.5

Step-by-step explanation:

9j - 5j > 20

4j > 20

j > 5

8j > -36

j > 4.5

Do you mean "write in slope-intercept form"?

In that case: The slope is -3/1 = -3. The y-intercept is where it crosses the y-axis, at -3. The form is y=mx+b, where m is the slope and b is the intercept, so it's y=-3x-3.

0.24 moles

Explanation: Using IDEAL GAS LAW

PV=nRT

where,

P = pressure of the gas= 2.0 atm

V = volume of the gas= 3.00L

T =Temperature of gas=25^0C=(25+273)K=298K

n = number of moles of gas=?

R = Gas constant = 0.0821 Latm/moleK

n=\frac {PV}{RT}=\frac {2.0\times 3.0}{0.0821\times 298}=0.24moles

C

Step-by-step explanation:

So we have:

To simplify, we can use the quotient rule of exponents, which says that if we have:

Then this equals:

So, our equation will be:

Subtract the exponents. Turn 1/5 into 2/10 by multiplying both layers be 2. Thus:

Subtract in the exponent:

So, our answer is C :)
