What is the constant of proportionality

Mathematics
2 answers:
IceJOKER [234]3 years ago
8 0

Answer:

2.5

Step-by-step explanation:

From the above, we see clearly that as x increase, y also increase. This means that y is directly proportional to x. With this understanding, we can calculate the constant(K) as illustrated below:

y & x

y = Kx

K = y / x

When x = 2, y = 5

K = 5/2 = 2.5

30 POINTS<br><br> why are 3/4 and 6/8 equivalent
Flauer [41]

Step-by-step explanation: In order to decide whether the given fractions are equivalent, first write each fraction in lowest terms. Remember, a fraction is written in lowest terms if the greatest common factor of the numerator and the denominator is 1.

For our first fraction which is 3/4, the greatest common factor of 3 and 4 is 1, the fraction is already in lowest terms.

For our second fraction however, since the greatest common factor of 6 and 8 is 2, we must divide both the numerator and denominator by 2 which gives us 3/4.

3/4 = 3/4 which means these fractions are equivalent.

3/4 and 6/8 are equivalent because if you reduce 6/8 in lowest terms, you end up with the fraction 3/4.

Write the quadratic equation whose roots are -6 and 6, and whose leading coefficient is 1 .
SCORPION-xisa [38]

Answer:

The quadratic equation is: y=x^2-36

Step-by-step explanation:

If the roots of the quadratic equation are "-6" and "6", then it must have the following factors:  (x+6)\,\, and \,\,(x-6)

Therefore, we can write the equation in factor form as:

y=a\,(x+6)\,(x-6)

where a is a real number constant factor. Now, this equation in standard form will look like:

y=a\,(x^2+6x-6x-6^2)=a\,(x^2-36)=ax^2-36\,a

Therefore, using the information about the leading coefficient being "1" (one), we derive that the constant  factor a must be "1". The final expression for the quadratic becomes:

y=x^2-36
