Y=5x+3
y=4x+6
5x+3=4x+6
5x-4x=6-3
x=3
y=5(3)+3
y=15+3
y=18
Answer:
-1266
Step-by-step explanation:
Hey there!
First, we'll need to isolate the y variable, meaning that we'll need all of the y's on one side. To do this, we'll need to subtract 8x from both sides. This leaves us with 2y = -8x - 10.
Second, we'll need to get y all by itself, without the 2. To do this, we'll need to divide both sides by 2. This leaves us with y = -4x - 5.
Therefore, your answer is the first option, or the darkest blue box.
Hope this helps!! :)
The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:
T(K) = T(°C) + 273.15;
So, T(K) = -25 + 273.15;
T(K) = 248.15;
The correct answer is a.
