To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.

<h3>What is cause-effect relationship?</h3>

A cause-and-effect relationship is one which satisfies some conditions like:

two events occur at the same time and in the same place
one event immediately precedes the other

Therefore, To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.

Answer:

$x=\frac{(a^2+ab)}{a-b}$

Step-by-step explanation:

So we want to make x the subject of the formula:

$a(x-b)=a^2+bx$

First, distribute the left side:

$a(x)-a(b)=a^2+bx\\ax-ab=a^2+bx$

Combine all the terms with x with it on one side. To do this, first subtract bx from both sides. The right side cancels:

$(ax-ab)-bx=(a^2+bx)-bx\\ax-ab-bx=a^2$

Remove the -ab from the left. Add ab to both sides. The left side cancels:

$(ax-ab-bx)+ab=a^2+ab\\ax-bx=a^2+ab$

Now, distribute out the x from the left side:

$ax-bx=a^2+ab\\x(a-b)=a^2+ab$

Divide both sides by (a-b). The left side cancels:

$\frac{(x(a-b))}{a-b}=\frac{(a^2+ab)}{a-b} \\x=\frac{(a^2+ab)}{a-b}$

Therefore:

$x=\frac{(a^2+ab)}{a-b}$

If j = k, then j + 9 = k + 9 represents which algebraic property

sleet_krkn [62]

Answer:

c) The given expression represents Addition Property of Equality.

Step-by-step explanation:

Here, the given expression is j = k

Now by ADDITION PROPERTY OF EQUALITY:

The property that states that if you add the same number to both sides of an equation, the sides remain equal.

So, if A = B ⇒ A + x = B + x

Now, here given that j = k

If we add the same number 9 on both the sides, the equation remains undisturbed.

⇒ j + 9 = k + 9

Hence, the above expression represents Addition Property of Equality.

Write an expression for “the quotient for y and 8”

jonny [76]

Answer:

Step-by-step explanation:

I think your answer is y/8. It's a little unusually worded. If this is not correct, please leave a note.

The way I have answered it, I would word it as "What is the quotient of y divided by 8."

5 to 7 and please solve with equations thx

padilas [110]

Answer:

Step-by-step explanation:

5) x + 5.4 < -1.6

x < -1.6 - 5.4

x < -7

6) x + 7.5 > -2.5

x > -2.5 - 7.5

x > -10

7) 3 ≤ 1/3 + x

x ≥ 3 - 1/3

x ≥ 5/3
