The label on the car's antifreeze container claims to protect the car between -30C and 130C. To convert Celsius temperature to F ahrenheit temperature, the formula is C= 5/9(F-32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car
1 answer:
Answer:
-22 ≤ temperature(F) ≤ 266
Step-by-step explanation:
Given that,
The label on the car's antifreeze container claims to protect the car between -30C and 130C.
Formula to convert Celsius temperature to Fahrenheit
<h3>C = 5/9 (F - 32)</h3><h3>9C/5 = (F - 32)</h3><h3>9C/5 + 32 = F</h3><h2>F = 9C/5 + 32 </h2><h3>1)</h3>
-30C = ?F
F =9(-30)/5 + 32
F = -22
<h3>2)</h3>
130C = ?F
F =9(130)/5 + 32
F = 266
The inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car is
<h3>-22 ≤
temperature(F) ≤ 266</h3>

5. 2√6
6. 4
Step-by-step explanation:
5. x =√[3×(3+5] = √3×8 =√24=2 √ 6
6. x(x+5)=6²
x²+5x=36
x²+5x-36=0
(x+9)(x-4) =0
x=-9 or x = 4
