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>
The answer i got was -3te with -t as an exponent
Answer:
First, you have to form simultaneous equation for both of their ages in yerms of a and b :
b = 4a - 12 -------- ( 1 )
a + b = 28 -------- ( 2 )
Next, you will have to solve it by substituting ( 1 ) into ( 2 ) :
a + (4a - 12) = 28
5a - 12 = 28
5a = 28 + 12
5a = 40
a = 8
Then, substitute a = 8 into ( 1 ) :
b = 4(8) - 12
b = 32 - 12
b = 20
the sum of inner angles of a pentagon is equal to
so:
and the largest one is 150
the answer is 1/16
the parallel line can be
y=2x+4
or any line with different y intercept
good luck
