Do the sides 4, 5, and 6 form a Pythagorean Triple?
NemiM [27]

Answer:

They do not form a Pythagorean Triple.

If it was a Triple,  4^2+5^2 should equal 6^2.

4^2+5^2=16+25=41

6^2=36

41≠26

It doesn't work, therefore it is not a Pythagorean Triple.

The amount of caffeine consumed from a glass of Diet Pepsi is proportional to the number of ounces that was drank. The table bel
Vilka [71]

Answer:

Constant of proportionality: k=3

Equation: c=3d

Step-by-step explanation:

By definition, Direct proportion equations have the following form:

y=kx

Where "k" is the Constant of proportionality.

In this case, let be "c"  the the amount of caffeine consumed  (in mg) from a glass of Diet Pepsi and "d" the number of ounces that was drank.

So, the equation that represents this relationship will have this form:

c=kd

Then, the first step is to find the Constant of proportionality "k".

Knowing that:

c=24;d=8

We can substitute values into the equation:

24=k(8)

Now, solving for "k", we get:

\frac{24}{8}=k\\\\k=3

Therefore, we can write the following equation that represents that proportional relationship:

c=3d

Which statements are true when using algebra tiles to solve the equation 8x + (–4) = 11x + 5?
kogti [31]

Answer:

See explanation

Step-by-step explanation:

You are given the equation 8x+(-4)=11x+5

1. Add 8 negative x-tiles to both sides of the equation to create a zero pair on the left side. The equation then will have form

8x+(-4)+(-8x)=11x+5+(-8x)\\ \\-4=3x+5

2. Add 5 negative unit tiles to both sides of the equation to create a zero pair on the right side. The equation now is

-4+(-5)=3x+5+(-5)\\ \\-9=3x

3. Divide both sides by 3:

\dfrac{3x}{3}=\dfrac{-9}{3}\\ \\x=-3
