Find the constant of variation k for the direct variation 4x = -y

Mathematics

MariettaO [177]3 years ago

Answer:

The constant of variation k is, -4

Step-by-step explanation:

The direct variation says that:

y \propto x, then the equation is in the form of:

y=kx        ....[1] where, k is the constant of variation.

As per the statement:

Given the direct variation:

4x = -y

Divide both sides by -1 we have;

-4x = y

or

y = -4x

On comparing with [1] we have;

k = -4

Therefore, the constant of variation k is, -4

Y=kx
solve for y

-y=4x
divide both sides by -1 aka times -1 both sides
y=-4x
y=kx

the constnat is -4

Simplify the rational expression. State any restrictions on the variable.
natulia [17]

Answer:

t+4, t≠8

Step-by-step explanation:

\dfrac{t^2-4t-32}{t-8}=\dfrac{(t+4)(t-8)}{(t-8)}=t+4

The value of t must not be one that makes the denominator zero, hence must not be 8.

Explain how to find which is greater 1/4 of 12 or 1/3 of 12
stiks02 [169]
1/3 would be greater because 
1/3 of 12= 4 while 
1/4 of 12 = 3
to check your work you would get a calculator (if possible) and divide 3by 12 or 4 by 12 then if you get .33 (divide 3 by 12 like 3/12) its 1/3. if its .25 (divide 4 by 12 like 4/12) its 1/4

Keri is making a doll clothes for a holiday craft show. The wholesale cost of the materials for one outfit is $9.38. If she sell
irinina [24]

Answer:

60%

Step-by-step explanation:

If I get you right, you're asking for the percentage gain to the nearest percentage, right?

Now to do this, we need to get the amount of profit she made. That's quite easy, we only need to subtract the cost price from the selling price. And that equals $15 - $9.38 that equals $5.62.

Now, we divide this value by the cost price and multiply by 100% to get the percentage gain.

I.e 5.62/9.38 × 100%.

That gives 59.9% , which equals 60% when approximated to the nearest percentage.

Find x, and then any unknown angles in the quadrilateral.<br> x= ?
sertanlavr [38]

Answer:

x=65

other angle= 165

Step-by-step explanation:

quadrilaterals always have a total of 360 degrees

because of this you can set up an equation and solve

360=90+40+x+(4x-95)

360=130+5x-95

360=35+5x

325=5x

65=x

plug this in to find missing angle

4(65)-95=165
