Answer:
1C
Step-by-step explanation:
1C.
Celsius is like fahrenheit except measured in a different way. 1 is greater than 0.3 so 1C would work the best.
Answer:
x = -84, y = -58
Step-by-step explanation:
2x - 3y = 6 --- Equation 1
Equation 1×5: <em>10x</em> - 15y = 30 --- Equation 2
5x + 7y = -14 --- Equation 3
Equation 3×2: <em>10x</em> + 14y = -28 --- Equation 4
<u>I will eliminate 10x. </u>
Equation 4-2:
10x - 15y - 10x + 14y = 30-(-28)
-y = 30+28
= 58
y = -58
Substitute y =-58 into Equation 1.
2x - 3y = 6
2x - 3(-58) = 6
2x - (-174) = 6
2x + 174 = 6
Find 2x.
2x = 6-174
= -168
Find x.
x = -168 ÷ 2
x = -84
Answer:
0 is not in domain
5 is not in domain
10 is in domain
Step-by-step explanation:
10 is in domain because inputting 10 into the function gives an output of 0
0 is not in th domain because 0 gives us the square root of a negative number, and the quare of a negative number isnt a real number
5 is not in the domain for the same reason
