0.4(2x + 0.3) = 1/3 (6x - 7.2)

x = 20.1

Step-by-step explanation:

First up you need to multipy the numbers on the outside with the ones on the inside

This would mean that

0.4(2x + 0.3) = 1/3(6x  - 7.2) will change to

0.8x + 0.12 = 2x - 2.4

You just have to solve for x now:

2.4 + 0.12 = 2x - 0.8x

2.52 = 1.2x

x = 2.1

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

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
