5y\(^2 - 16y - 380 = 0\)
5y\(^2 - 24y - 380 = 0\)
5y\(^2 - 16y - 330 = 0\)
5y\(^2 + 24y - 324 = 0\)
Correct answer is D
Man = x, Son = y
x = 5y
(x + 4)(y + 4) = 350
(5y + 4)(y + 4) = 340
5y\(^2\) + 20y + 4y + 16 - 240 = 0
5y\(^2\) + 24y - 324 = 0
The expression \(\frac{5x + 3}{6x (x + 1)}\) will be undefined when x equals
{0, 1}
{0, -1}
{-3, -11}
{-3, 0}
Correct answer is B
6x(x + 1) = 0
When 6x = 0 and
x + 1 = 0
x = 0 and x = -1
(0, -1)
Find the equation of the line parallel to 2y = 3(x - 2) and passes through the point (2, 3)
y = \(\frac{2}{3} x - 3\)
y = \(\frac{2}{3} x - 2\)
y = \(\frac{2}{3} x\)
y = \(\frac{-2}{3} x\)
Correct answer is C
2y = 3(x - 2)
\(\frac{2y}{2} = \frac{3x}{2} - \frac{6}{2}\)
y = \(\frac{3}{2}x - 3\)
m = \(\frac{3}{2}\)
\(\frac{y - y_1}{x - x_1}\) = m
\(\frac{y - 3}{x - 2} = \frac{3}{2}\)
2y - 6 = 3x - 6
\(\frac{2y}{2} = \frac{3x}{2}\)
y = \(\frac{3}{2}\)x
In the diagram, PQ // SR. Find the value of x
34
46
57
68
Correct answer is B
x + 68\(^o\) + 246\(^o\) = 360\(^o\)
x + 314\(^o\) = 360\(^o\)
x = 360\(^o\) - 314\(^o\)
x = 46\(^o\)
280 cm\(^2\)
166 cm\(^2\)
140 cm\(^2\)
83 cm\(^2\)
Correct answer is B
Total = 2(LB + BH + LH)
Surface area
= 2(7 x 5 + 5 x 4 + 7 x 4)
= 2(35 + 20 + 28)
= 2(83)
= 166cm\(^2\)
