HELLO? IM SHOUTING FROM OUTER SPACE PLEASE COME HELP! lol The equation $y = -6t^2 + 51t$ describes the height (in feet) of a projectile launched from the surface of Mars at 51 feet per second. In how many seconds will the projectile first reach 108 feet in height? I'll mark you as the brainliest answer if it's correct!!! No one answered so im increasing points

(40 points) i need some . an answer definition is appreciated as well.

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities

Graph the following system of linear inequalities. identify at least two points in the solution: y < 5 - 2x | x + 5y > -7
