Express using algebra. jane is 3 years older than mary, and mary is twice as old as kay. if kay is x years old, how old is jane?

2x+3

Step-by-step explanation:

Kay=x

Mary is twice as old as kay so that makes her 2x

Jane is 3 years older then Mary so that makes her 2x+3

Kay=x

Mary=2x

Jane=2x+3

so that makes the answer 2x+3

Hope this helped!

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

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
