Answer:
I am just trying to help but by the looks of it, it could be the right, if its wrong so sorry.
Step-by-step explanation:
39 x 10
= 390
39 x 40 (390 x 4)
= 1,560
39 x 2
= 78
1,560 - 78
= 1,482
ANSWER: 1,482
From the system of equations given, it is correct to state that:
- System A has two real solutions
- System B has two real solutions
- System C has one real solution.
<h3>What are system of equations?</h3>
System of equations refers to a matrix that has elements which are representative of the coefficients of the given equations.
<h3>What are the solutions to the above systems of equations?</h3>
System A:
x² + y² = 17
y = -1/2x
The two real solutions to the above system is given as:
and
System B:
y = x² - 7x + 10
y = -6x +5
The two real solutions to the above system is given as:
System C
y = -2x² + 9
8x-y = -17
The one real solution is given as:
x = -2, y = 1

The range is the difference between the highest and lowest pays.
Highest pay: GS-5 - 2,252
Lowest pay: GS-1 - 1,461
Range = 2252 - 1461 = 791
The answer is D. $791
