The equation of the line in the graph is
Answer Details
Gradient of line = Change in yChange in x=y2−y1x2−x1 Change in y Change in x = y 2 − y 1 x 2 − x 1
y2 = 0, y1 = 4
x2 = 3 and x1 = 0
y2−y1x2−x1=0−43−0=−43 y 2 − y 1 x 2 − x 1 = 0 − 4 3 − 0 = − 4 3
Equation of straight line = y = mx + c
where m = gradient and c = y
intercept = 4
y = 4x + 43 4 3 , multiple through by 3
3y = 4x + 12
Given that for sets A and B, in a universal set E, \(A \subseteq B\) then \(A \cap (A \cap B)^{1}\) is
Evaluate \( \frac{1}{3} \div \left[\frac{5}{7}\left(\frac{9}{10}-1+\frac{3}{4}\right)\right] \)
Evaluate \( \frac{0.36 \times 5.4 \times 0.63}{4.2 \times 9.0 \times 2.4} \)
Without using table, solve the equation \(8x^{-2} = \frac{2}{25}\)
Solve for x if 25x + 3(5x) = 4
Evaluate \( \frac{\log_{5}(0.04)}{\log_{3}18-\log_{3}2} \)
Given that \( \sqrt{2} = 1.1414 \), find without using tables, the value of \( \frac{1}{\sqrt{2}} \)
Simplify \( \sqrt{48} - \frac{9}{\sqrt{3}} + \sqrt{75} \)
