Graph the following system of equations:
2x + 3y = -6
x - 3y = 15
what is the solution to this system?

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?

Pls math have no ideamultiply and simppify. 2x^2y^3z^2 • 4xy^4x^2

Find the value of x. also give me an explanation so i can complete it to other questions as well, : )
