Answer:
x>-15 degrees
Step-by-step explanation The question states that the temperature has to stay above 15 so then it could be anything above -15 degrees.
Midpoint is : (x1 + x2) / 2 , (y1 + y2) / 2
(-1,3)....x1 = -1 and y1 = 3
(7,-1)...x2 = 7 and y2 = -1
now we sub and solve
m = (-1 + 7)/2 , (3 - 1) / 2
m = (6/2, 2/2)
m = (3,1) <===
The angle is 3 and 1 diameter
Answer:
25/10
Step-by-step explanation:
Make the fractions improper by multiplying the whole number by the denominator and then adding the numerator (if this makes sense).
This makes 5x10=50+3=53/10
Do the same for the second fraction. 2x5=10+4=14/5
Then make the denominators the same, and in this case all you need to do is multiply both sides of 14/5 by 2, so that makes 28/10.
Now, just take it away.
53/10-28/10=25/10, which can be then simplified into 2 1/2 or 5/2.
