-4x+ lly = 15

pls help me

x=2y

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

What can each term of the equation be multiplied by to eliminate the fractions before solving? x – + 2x = + x 2 6 10 12

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1
