A 4-column table with 4 rows. Column 1 is labeled x. Column 2 is labeled y. Column 3 is labeled x + y = 56. Column 4 is labeled 2 x minus 7 = y. All rows are blank. Using the guess and check technique, find two numbers that satisfy both conditions.

The sum of the two numbers is 56.

The second number is seven less than two times the first number.

What is the value of the first number, x?

step-by-step explanation:

true

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

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
