What is the graph of f(x) =100(0.7)x

1 answer:

7 0

Simplify your equation to f(x)=70x which is the same thing as f(x)=70x+0. But I need to see the answer choices to fully answer this question. Sorry :(

Suppose y varies directly with x, and y = 12 when x = 2. What direct variation

neonofarm [45]

Answer:

$y=24$

Step-by-step explanation:

Given:

$y=kx$

Substitute:

$\left \{ {{y=12} \atop {x=2}} \right.$ into $y=kx$

$12=k\times2$

Swap the sides:

$k\times2=12$

Divide both sides of the equation by the coefficient of variable:

$k=\frac{12}{2}$

Cross out the common factor:

$k=6$

Find the equation of the function:

$y=6x$

Substitute:

$y=6\times4$

Calculate the product or quotient:

$y=24$
