Answer:
h = -4
Step-by-step explanation:
7h-5(3h-8) = 72
Distribute
7h - 15h +40 = 72
Combine like terms
-8h +40 = 72
Subtract 40 from each side
-8h+40-40 = 72-40
-8h = 32
Divide each side by -8
-8h/-8 = -32/-8
h = -4

Step-by-step explanation:
Answer:
y = -7x+4
Step-by-step explanation:
We can use the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
We know the slope
y = -7x+b
We have a point to substitute in for x and y
-3 = -7(1) +b
-3 = -7+b
Add 7 to each side
-3+7 =b
4 =b
We can substitute this back into
y = -7x+b
y = -7x+4
The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F
- Thermometer accuracy = ±2°F
- Thermometer reading = 17°F
<u>The least possible value of </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u><u> </u><u>thus</u> :
- Thermometer reading - thermometer accuracy
<u>The highest possible </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u> thus :
- Themometer reading - thermometer accuracy
Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
