If y varies inversely as x and x is 6 when y is 13, what is x when y is 8? a.9.75 b.3.69 c.0.27 d.6.5

a.9.75

Step-by-step explanation:

When two quantities x and y are in inverse proportion, then we equation shows inverse variation is given by :-

Now, if y varies inversely as x and x is 6 when y is 13, then at y =8 , we have

Hence, if y varies inversely as x and x is 6 when y is 13, then when y is 8 , x=9.75.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
