What’s the answer is the answer
-x + 7 = x - 5
add x to both sides of the equation
7 = 2x - 5
add 5 to both sides of the equation
12 = 2x
divide 2 from both sides of the equation
6 = x
We have that
<span>f(x)=-x+0.5
g(x)=x</span>²+3x-4
f(x)=g(x)------------> -x+0.5=x²+3x-4-------------> x²+3x-4+x-0.5=0
x²+3x-4+x-0.5=0---------------> x²+4x-4.5=0
using a graph tool
see the attached figure
the solution are the points (-4.915,0) and (0.915,0)
The expression
can be used to convert any Celsius temperature into its corresponding Fahrenheit temperature.
We have to determine the Fahrenheit temperature corresponding to -10 degree Celsius.
C = - 10
Consider the expression ![1.8C+32](https://tex.z-dn.net/?f=1.8C%2B32)
= ![(1.8 \times C)+32](https://tex.z-dn.net/?f=%281.8%20%5Ctimes%20C%29%2B32)
= ![(1.8 \times -10)+32](https://tex.z-dn.net/?f=%281.8%20%5Ctimes%20-10%29%2B32)
= ![-18+32](https://tex.z-dn.net/?f=-18%2B32)
= 14 degree Fahrenheit
Therefore, the Fahrenheit temperature corresponding to -10 degree Celsius is 14 degree Fahrenheit.
