One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 709, find the numbers.

First number:87

Second number:435

Third number:187

Step-by-step explanation:

First number=x

Seconded number=x•5

Third number=x+100

X+5x+(X+100)=709

7x+100=709

7x=609

87

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

x = 3 ± √(5+y)
