Write the following using algebraic notation, using the letter x for any unknown number: i think of a number, add two then multiply by three

3(x + 2)

Step-by-step explanation:

i think of a number: x

add two: x + 2

then multiply by three: 3(x + 2)

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

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
