Answer:
Step-by-step explanation:
<u>Put input value instead of the x into equation and calculate the output:</u>
<u>x = -4, then find the value of y:</u>
- y = -5(-4) - 7 = 20 - 7 = 13
The output is 13 when the input is -4
Answer:
x=7/2, y=3
Step-by-step explanation:
3x-2(10-2x)=22
3x-20+4x=22
7x=2
x=7/2
y=10-2(7/2)
y=3
Answer:
t > 4.5
Step-by-step explanation:
T = 5 - 2t
is the equation for the temperature after midnight.
-4 = 5 - 2t is the point of interest
-9 = -2t
t = 4.5 hrs so 4:30 is the time the temperature reaches -4
t > 4.5 hrs covers all the time that the temperature is less than -4
