Divide, the first operation is the parentheses and then division
Answer:
(-1,1)
Step-by-step explanation:
All you have to do is plug it in the equation:
(x,y)
For (-1,1)
1=2(-1)+1
Simplify:
1=-1 but you know that 1≠-1 so (-1,1) is not it
For (3,7)
7=2(3)+1
Simplify:
7=7
For (-3,-5)
-5=2(-3)+1
-5=-5
Simplify:
For (0,1)
1=2(0)+1
1=1

The length of the segment x is 16.2
Step-by-step explanation:
Here apply the Pythagorean relationship which states that the sum of squares of the sides is equal to the square of the hypotenuse.
Mathematically,
a²+b²=c²
where a=15, b=6, c=r
Hence;
15²+6²=c²
225+36=c²
√261=c
16.16
x⇒16.2
