We have two numbers say a, b. And a system of equations.

It looks a bit intimidating but it's actually very easy.
Instead of term a + b in the second equation we can say it's zero because the first equation describes a + b as being equal to 0.
So,

The above equation is not true therefore numbers a and b do not exists in the real number domain.

No solution.
Hope this helps.
Answer
Find out how many eighty fours are in 672.
To prove
Let us assume that the number of the 84 be x .
As given in the equation
Total values given in the question be 672.
Than the equation becomes
84 × x = 672
Simplify the above equation
84x = 672

x = 8
Therefore the Numbers of eighty fours in 672 is 8 .
Answer:
<h2>There's only one person who has a tie, wears a hat and is not from North.</h2>
Step-by-step explanation:
Givens
- There are 4 people in the group.
- 3 of them have tie.
- 3 of them wear a hat.
- 3 of them are from the North.
- But, just one of them has a tie, wear a hat and is from the Nprth of Mexico City.
From the given information you can notice that only one of them is not from the North, and the one that has all three qualities is from North.
Therefore, there's only one person who has a tie, wears a hat and is not from North.
Answer:
A.
Step-by-step explanation:
Perpendicular => so it will have a slope of negative reciprocal to this slope
Slope = 2/3
Now
Point = (x,y) = (6,5)
So,
x = 6, y = 5
Substituting in the slope intercept form
5 = (2/3)(6)+b
5 = 4+b
=> b = 1
So, we have
m = 2/3
b = 1
Putting in the slope intercept equation
y = 2/3x+1
