Find the answer plz OR I WILL YEET YOU.

7/2x -3(5x -1/2)

Step-by-step explanation:

Original equation:

7/2x - 3(5x - 1/2) = ?

Use distributive property for the parentheses

-3 · 5x = -15x

-3 · (-1/2) = 3/2 or 1.5

Plug these values into the equation

7/2x - 15x + 1.5 = ?

Combine like factors

-11.5x + 1.5 = a (a = answer)

The equation with fractions:

-11 1/2 + 1 1/2 = a

Hope this helps :)

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

it would open into a square depending on the type of envelope i’m not sure about the second part
