Answer:

Step-by-step explanation:
Coordinates of Point b
b lies on the circle whose equation is 

Comparing with the general form a circle with center at the origin: 
The radius of the circle =17 which is the length of the hypotenuse of the terminal ray through point b.
For an angle drawn in standard position through point b,
x=-8 which is negative
y=15 which is positive
Therefore, the angle is in Quadrant II.

Hi! The temperature would be 18°.
There was a 4 hour period between 5 and 9 a.m.
So, I just took -10, and added 7 four times.
-10 + 7 + 7 + 7 + 7 = 18
Hope this helps you! Happy thanksgiving, here's a turkey!

A mathematical sentence which contains an inequality symbol and one variable raised to the first power is called a linear inequality.
3x+15=0
<=> 3x=-15
<=> x= -15/3
<=> x= -5
Vậy nghiệm của đa thức 3x+15 là -5
