3/4+?/2=13/4 what is answer

Otrada [13]

The answer is x=5.

Solve for x. (The question mark should be x.)

$\frac{3}{4}+\frac{x}{2}=\frac{13}{4}\\\frac{3}{4}+\frac{x}{2}-\frac{3}{4}=\frac{13}{4}-\frac{3}{4}\\\frac{x}{2}=\frac{5}{2}\\\frac{2x}{2}=\frac{5\times 2}{2}\\x=5$

Function A:

Slope = change in y/Change in x

= (9-3)/(3-0) = 6/3 = 2

Function B:

Clearly the slope is 3

(y = mx + c, m is the slope)

Rate of change of B is more than A
