Answer:
≈ 17.03 ( to 2 dec. places )
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √(x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 7, - 2) and (x₂, y₂ ) = (6, 9)
d = 
= 
= 
=
≈≈ 17.03

Answer:

Step-by-step explanation:
To start with;
Represent the budget of education by x
Represent the budget of defense by y
From the question, we understand that:
y exceeds x by $622.7 billion
Mathematically. this can be represented as:

<em>Hence, the defense budget is x + $622.7 billion</em>
