Josette found 16 coins in her purse. She had 2 more nickels than pennies and 7 fewer quarters than pennies. Josette modeled the scenario in a table and then wrote the equation p + (p + 2) + (7 – p) = 16. A 2-column table with 3 rows. Column 1 has entries pennies, nickels, quarters. Column 2 has entries p, p + 2, blank.

Is Josette’s equation correct? If not, what was her mistake.
Her equation is correct.
The variable should have been the number of nickels.
Instead of finding the sum, she needed to write an equation to find the
difference.
The number of quarters was translated incorrectly and should be p – 7.

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

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
