How many solutions does y=5-2x and4x+2y=10

infinite solutions

Step-by-step explanation:

y=5-2x

4x+2y=10

Multiply the first equation by 2

2y = 10 -4x

Add 4x to each side

4x+2y = 10

This is identical to the second equation

This means they are the same line, so there are infinite solutions along the line

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
