I'm stuck in this exercise, help me. I will type according to what is written here. The temperature t of a greenhouse (in degrees Celsius) is determined, depending on the time of day, by the expression t = -h² + 22h-85.

a) What is the temperature in that greenhouse at 8 am?
b) What time does the temperature reach 36 ° C?

To solve the letter a, just replace the temperature value instead of x.

To solve the letter a, just replace the temperature value in place of y.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
