Is 6 a solution to the equation x^2 - 4 = 5x? Please tell me why or why not

Mathematics

TEA [102]3 years ago

Answer:

6 is not a solution to the given equation.

Step-by-step explanation:

We are given the equation x^2-4=5x

We need to know whether or not x=6 is a solution. This means that we should substitute in 6 for each instance of x. Then, if both sides of the equation are equal, then 6 is a solution to the equation.

x^2-4=5x\\\\(6)^2-4=5(6)\\\\36-4=30\\\\32=30

As 32 ≠ 30, 6 is not a solution to the given equation.

Umnica [9.8K]

Answer: a.This is the average number of days the house stayed on the market before being sold for $150,000.


Step-by-step explanation:

Given: f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s.

To find the meaning f(150),

here p= 150 which means f(150) is the average number of days a house stays on the market before being sold for price 150 in $1,000s.

And 150 in $ 1,000= $150,000

Therefore, f(150) is the average number of days a house stays on the market before being sold for price $150,000.

Find the greatest common factor of the terms in the following expression 18x+12xy​
Anarel [89]
<h3>Answer:   6x</h3>

=============================================

Explanation:

Ignoring the variables for now, the GCF of 18 and 12 is 6. This is the largest factor found in both values

  • 18 = 6*3
  • 12 = 6*2

Now let's consider the variables. Both terms have an 'x' in them, but not a y. This means x will be tacked on the 6 we found earlier to get the overall GCF to be 6x.

Note how

18x + 12xy = 6x*3+6x*2y = 6x(3+2y)

Showing we can factor out the GCF using the distributive property.
