14.2t−25.2=3.8t+26.8
T=

t = 5

Step-by-step explanation:

14.2t - 25.2 = 3.8t + 26.8

<=> 14,2t - 3.8t = 25,2 + 26,8

<=> 10,6t = 52

<=> t = 5

529 and 531

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
