Which fraction is halfway between 3/7 and 10/21a.) 7/15b.) 19/42c.) 15/42d.) 4/9

B) 19/42

Step-by-step explanation:

To find the fraction halfway between 3/7 and 10/21 we first find the difference between the fractions, half it, and then add it back on to the smaller one.

Because 10/21 > 3/7 we subtract in that order

Half of 1/21 is 1/42 and so the fraction halfway between 3/7 and 10/21 is

- 70

this is the answer for you hope it

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
