Tyrone's age is 2 years less than 4 times his younger sister's age. if his younger sister's age is b years, which of the following expressions best shows tyrone's age?
4b
b − 2
2b − 4
4b − 2

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
