2x+y=-6 the equation has to be in slope form (y=mx+b) the first thing that you have to do is find the slope which you can do fairly easy by moving the 2x to the other side of the equation. Y=-2x-1 then you use that slope and use a different y intercept for the two lines to be parallel
Answer:
Step-by-step explanation:
We are given the temperature inside the machine from startup until 10 seconds later, the formula is:
We want to know at what time t the temperature inside the machine will be equal to 128 °C.
So we set:
Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side
and we simplify:
now it's easy to solve for t:
And thus we arrive to the solution.
Using Algebra I have concluded that the answer is 12.5 kilometers per liter. :D
First set up your equation
Then multiply by 100
Hope this helps!
