Step-by-step explanation:
y = - 8x + 12
<u>Factorise:</u>
<u></u>
= (x - 6)(x - 2)
<u>Find solutions by equating to 0:</u>
<u></u>
x - 6 = 0
x = 6
or
x - 2 = 0
x = 2
<u>Write down solutions:</u>
<u></u>
x = 6,
x = 2

3x27=81 so 81 is a multiple of 3
there is no integer x for which 4x=46 so 46 is not a multiple of 4
there is no integer x for which 7x=55 so 55 is not a multiple of 7
72 = 8*9 so 72 is a multiple of 9
there is no integer x for which 6x=45 hence 45 is not a multiple of 6
Answer:
Proved
Step-by-step explanation:
Given
Prove that
Multiply the numerator and denominator by 1 + sinx
Combine both fractions to form 1
Expand the denominator using difference of two squares;
The expression becomes
From trigonometry;
The expression becomes
Divide the numerator and the denominator by cos x
Split fraction
From trigonometry;
So;
=
