Answer:
45.8 degrees
Step-by-step explanation:
We know that the temp before take off is 57.9
We also know the temp decreases every 1,000 feet so
if we are 11,000 feet in the air and divide that 11000/1000=11
We know that the temp drops 11 times
11x1.1=12.1
57.9-12.1=45.8 degrees
Answer:

Step-by-step explanation:
Here we are given two coordinates through which our lines passes through. Now we are going to use the two point form to find the equation of the line.
The two point form is given as

Here we are given two coordinates . Thus replacing them in the formula and simplifying it will give us the equation of the line.




adding x and 6 on both sides we get

Hence this is our equation of the line passing through (5,6) & (4,7)
I think it should be 50, really sorry if it wasn't multiplying.
So firstly, what two terms have a product of 8x^2 and a sum of 9x? That would be x and 8x. Replace 9x with x + 8x: 
Next, factor x^2 + x and 8x + 8 separately. Make sure that they have the same quantity on the inside: 
Now you can rewrite the equation as 
Now using zero product property, solve for x:

<u>In short, the solutions are {-1,-8}, or C.</u>
