Answer:
If x can only have one answer, then the solution is one value. If x can be all real numbers, then the solution is all real numbers. And if x doesn't have an answer then it has no solution.
Step-by-step explanation:
For example:
One value: 7 + x= 10 => x= 3
All real numbers: 0x=0 => x can be all real numbers
No solutions: 7x=6x => no solutions

((10+2)•3^2 ) -2= 12•9-2=108-2=106
Answer:
B(-1,-3)
Step-by-step explanation:
let the coordinates of B be (x,y)
Mid point of AB = (x₁+ x₂/2, y₁+y₂ /2)
= (-3 +x/2 , -5+y/2)
Mid point of AB is M(-2,-4)
(-3 +x/2 , -5+y/2) = (-2, -4)
-3 + x /2 = -2 ; -5+y/2 = -4
-3 + x = -2 * 2 ; -5 + y = -4 * 2
-3 + x = -4 ; -5 + y = -8
x = -4 +3 ; y = -8 +5
x = -1 ; y = -3
B(-1,-3)
Answer:
40 minutes
Step-by-step explanation:
We can solve this problem through finding the proportion...
Let the time taken to travel 8 inches at the speed be x
Hence, 12:60 :: 8:x
We must multiply the extremes and the nears..
Hence,
12x=60×8
x=60×8/12
x=40 minutes
