The slope is -4.7 because this equation is written in point slope form. This equation can be rewritten as y = -4.7x + 21. Point slope form is y = mx + b, with m being slope and b being y-intercept.
G(x) = F(x + 4) + 2
Addition of a number to x indicates a shift towards left. Since 4 is being added to x, this means function is shifted to left by 4 units.
Addition of a number to the function represent an upward shift. Since 2 is being added to the function value, this mean function is shifted up by 2 units.
So, G(x) is obtained by shifted F(x) 4 units to left and 2 units up.
Thus, option C is the correct answer
Answer:
K still the same value
Step-by-step explanation:
given a reaction aA+bB<->cC+dD the constant K is defined as:

K is a constant so it won't change the value. Instead, the values of C and D are going to change. The position of equilibrium moves because of the need to keep a constant value for the equilibrium constant.
The percent increase in the iron was 50%. 1.2/2 = .6 1.2 + .6 = 1.8
