It would be 40°F, the temperature drops down 2 degrees in one hour, and theres 3 hours til 3:00am, so it dropped 6° then it would 28°F, then it adds 3° every hour until 7:00am, which is 4 hours, so that would be 28°F+12°F= 40°F
The point of intersection is the point where two or more functions meet.
The graphs of the hyperbola and ellipse have 0 point of intersection
The given parameters are:
To determine the points of intersection, we simply equate both equations.
So, we have:
Cancel out the common terms
Collect like terms
Divide through by 5
Divide through by y
<em>The system of equation does not give room to calculate the x-coordinate at the x-axis.</em>
<em />
Hence, the graphs of the hyperbola and ellipse have <em>0 point of intersection</em>

Answer:
When did Mary and Wyatt meet? 0.5 minutes later
How far from point Q did they meet? 3.5 km
Step-by-step explanation:
Mary’s motion is represented by d = 8t----(1)
Wyatt’s motion is represented by 2d + 14t = 15----(2)
We solve for d in equation (2) to get:d=7.5-7t----(3)
We equate equation (1) and (3) to get:
We now solve for t to get:
Now put t=0.5 into equation (1) to get d=0.5*8=4
This means they met 4 km from point P.
Therefore they meet 7.5-4=3.5km from point Q
Answer:
80°
Step-by-step explanation:
sides of angle =180°
y= 180-(45+55) = 80°
x=y because x is vertically opposite to y
therefore x =80°
