Find formulas for x, y, and z in terms of a, b, and c. it may be necessary to make assumptions about the size of a matrix in order to produce a formula.

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
