To solve this problem, you should first convert all temperatures to one temperature scale. I'll use the formula to convert Fahrenheit to Celsius. It is C = 5/9(F - 32), where F is the degrees Fahrenheit.
Let's start converting.
C = 5/9(-5 - 32) C = 5/9(-37) C = -185/9 C = -20.6°
C = 5/9(40 - 32) C = 5/9(8) C = 40/9 C = 4.4°
Now let's arrange them from least to greatest: -20.6°C, -8°C, 4.4°C, 10°C.
That is where the line crosses the x axis or where y=0
0=-16x^2+22x+3 we gon do grouping ac method -16 times 3=-48
what 2 numbers multiply to get -48 and add to get 22 -2 and 24 0=-16x^2-2x+24x+3 group 0=(-16x^2-2x)+(24x+3) undistribute 0=-2x(8x+1)+3(8x+1) undistribute 0=(8x+1)(-2x+3) set eaqual to 0
