The answer will be 10/3 also I'll recommend downloading photo math it really helps!! It's free.
I’m pretty sure the answer is A. and B.
Answer:
yes, the two expressions are equivalent when x = 5
Step-by-step explanation:
7(5)=35
3(5)=15
35+15=50
9(5)=45
45+5=50
Step-by-step explanation:
Let there be point X whose coordinates are (a2,b2) and point Y whose coordinates are (a1,b1)
Using distance formula ,


Distance formula will be

Answer:
(x-7)² + (y+1)² = 4² or (x-7)² + (y+1)² =16
Step-by-step explanation:
1) coordinates of the center
x0=(x1+x2)/2=(7+7)/2=7
y0=(y1+y1)/2=(3-5)/2 = -1
(7, -1) - coordinates of the center
2) radius of the circle
length of the diameter =√((x2-x1)²+(y2-y1)²)=√((7-7)²+(-5-3)²)=√(8)²= 8
r = length of the radius = length of the diameter / 2 = 8/2 = 4
3) the equation of the circle
(x-x0)² + (y-y0)²= r²
(x-7)² + (y+1)² = 4²=16
