Answer:
It should be 0°
Step-by-step explanation:
If it decreases 4 degrees every hour and you put into a line graph, you would get 0 degrees in 3 hours.
The answer is C because we can say that the x value is the input and the y value is the output therefore as the 4 is subtracted after the function the output decreases by 4 and the y values must therefore decrease by 4.
<h3>Answer:</h3>
ellipse
<h3>Explanation:</h3>
Written in general form, the equation is ...
... x² +2y² -4y = 0
The coefficients of the squared terms are the same sign, and of different values, so the equation is of an ellipse.
These are the other possibilities that can be determined from the coefficients of the squared terms.
- Same sign, same value: circle.
- Opposite sign: hyperbola.
- Only one squared term: parabola.
_____
Of course, your handy graphing calculator can show you the graph, making it easy for you to determine the conic section that is described.
To find 20% of 950 you would set it up as a proportion. When doing percentages the prevent is always out of 100 so the first step would be 20/100. You are trying to find a number out of 950 so the second part would be ?/950. Now you want to cross multiply and divide. 20*950=19,000 then you divide it by 100 (your other number) 19,000/100=190. So 20% of 950 is 190.
Okay so the answer is x= 9.5 y= 9
