Linear functions are straight lines. They are usually in the form of y = mx + c. This is called slope intercept form because m represents the slope and c represents the y intercept.

There is another form Ax + By = C. This form is called general form. From this form we can determine the y - intercept by setting X = 0 and the X intercept by setting y = 0.

If you need any other descriptions please ask me.

What is the correct factorisation of?<br>X^2+6x+8

MaRussiya [10]

Answer:

Step-by-step explanation:

Given that: x

+6x+8

+4x+2x+8, (split middle term)

=(x

+4x)+(2x+8), (group pair of terms)

=x(x+4)+2(x+4), (factor each binomials)

=(x+4)(x+2), (factor out common factor (x+4)

Hence factors of x

+6x+8 are (x+4)(x+2)

31,50 is 42% os what number

sergeinik [125]

$\frac{31,50}{x}=\frac{42}{100}$

The right fraction represents the percentage; 42 over 100 (100 is the total), or 0.42.
The left fraction is the part number over the whole number. The whole number is unknown, so we use 'x'.

$\frac{31.50}{x} = \frac{42}{100}\\\\cross\ multiply\\\\31.50\times100=3150\\42\times x=42x\\\\3150=42x\\x=75$
Your answer is 75.

What kinds of functions can be integrated using partial fraction decomposition? Choose the correct answer below

zaharov [31]

Answer:

B. Rational functions

Step-by-step explanation:

The partial fraction decomposition is used for functions there are described by fractions, and for which the substitution method is not possible. These are rational functions, in which both the numerator and the denominator are polynomials.

So the correct answer is:

B. Rational functions
