Hello,
The 2 curves (lines) have the same value of y for:
y=4-x
y=2x+3
==>4-x=2x+3
==>3x=1
==>x=1/3
And y=4-1/3=11/3
Sol={(1/3,11/3)}
If the temperature is the same in Farenheit and Celsius, the variable F is equal to the variable C in the equation. Thus, you'll just need to replace one or both variables in the original equation and solve for the single variable. I'll just use x as the variable here:
F = 1.8C + 32
x = 1.8x + 32
subtract x from both sides
0 = 0.8x + 32
subtract 32 from both sides
-32 = 0.8x
divide both sides by 0.8
-40 = x
So, since we know x = -40 degrees, we also know that F = -40° and C = -40° too.
46-(-26)
= 46+26
= 72
As - and - together makes plus.
Hope it helps you and please mark my answer as the brainliest
Do others with yourself please ,I'll answer to your any question if can.
Answer: 6
