3x + 4y - 23 = 0
3x + 4y +23 = 0
3x - 4y +23 = 0
3x - 4y - 23 = 0
Correct answer is D
\(\frac{3}{4} = \frac{y + 5}{x - 1}\)
3(x - 1) = 4(y + 5)
3x - 3 = 4y + 20
3x - 4y - 23 = 0
\(\frac{2}{3}\)
\(\frac{3}{5}\)
\(\frac{7}{20}\)
\(\frac{12}{25}\)
Correct answer is C
(\(\frac{2}{5} \times \frac {3}{5}) + (\frac{3}{5} \times \frac{2}{5})\)
\(\frac{6}{25} + \frac{6}{25} = \frac{12}{25}\)
80\(^o\)
60\(^o\)
40\(^o\)
30\(^o\)
Correct answer is B
3\(x^o\) + 2\(x^o\) + 4\(x^o\) + 3\(x^o\) + 6\(x^o\) = 540\(^o\)
\(\frac{18x^o}{18} = \frac{540^o}{18}\)
\(x^o\) = 30\(^o\)
Smallest angle = 2 x 30\(^o\) = 60\(^o\)
Factorize completely; (2x + 2y)(x - y) + (2x - 2y)(x + y)
4(x - y)(x + y)
(4(x - y)
2(x - y)(x + y)
2(x - y)
Correct answer is A
(2x + 2y)(x - y) + (2x - 2y)(x - y)
2(x + y)(x - y) + 2(x - y)(x + y)
4(x - y)(x + y)
100\(^o\)
120\(^o\)
140\(^o\)
160\(^o\)
Correct answer is A
S\(O\)T = 180\(^o\) - (50 + 50)
= 80\(^o\)
P\(Q\)R = 80\(^o\)
= \(\frac{360^o - 160^o}{2}\) = 100\(^o\)
