Solve the equation.

|x + 7| = 12

select one:

a.
{–19, –5}

b.
{–19, 5}

c.
{–5, 19}

d. {5, 19}

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
