5. Mitchell works in a lab. He plans to
mix a 35% solution of acid with an
80% solution to make 70 mL of a 50%
solution. Let x represent the number
of millilitres of 35% solution. Use the
equation 0.35x + 0.8(70 – x) = 0.5(70)
to find the volume of each type of acid
used in the mixture.

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

its very big question plz make it small
