Answer:
C. (15/2,9/2)
Step-by-step explanation:
To find the midpoint of two points
midpoint = (x1+x2)/2 , (y1+y2)/2
= (17+-2)/2, (1+8)/2
= 15/2, 9/2
consecutive integers have a difference of 1 between them
let the brothers have ages n , n + 1 and n + 2 thus
n + n + 1 + n + 2 = 96
3n + 3 = 96
subtract 3 from both sides of the equation
3n = 96 - 3 = 93
divide both sides by 3
n =
= 31
The ages are 31 , 32 and 33
Step-by-step explanation:
The given equation is :
2x+7y=11
We need to tell the point (-5,3) lies on the graph of the above equation of not.
Put x = -5 and y = 3 in the LHS of the above equation.
LHS = 2x+7y
= 2(-5)+7(3)
= -10 +21
= 11
It means, when we put x = -5 and y = 3 in the above equation, we get 11. Hence, (-5,3) lies on the graph of the equation.
Answer: 8x^2° + 52x° + 27°
Using the knowledge i know i think this is the right answer
Have a great day :)
