A system of equations is shown below. Which statement about the ordered pair (-7,-3) is true?
2 answers:
Answer: C) It is the only solution to the system. Step-by-step explanation: 3x + 3y = -30 2x + y = -17 3(-7) + 3(-3) = -30 -21 + -9 = -30 -30 = -30 True 2x + y = -17 2(-7) + (-3) = -17 -14 + -3 = -17 -17 = -17 True
The lines defined by the equations are not parallel and the point is a solution to both of them. It must be the point of intersection so it is the only solution to the system

The equation for finding the hypotneus of a right triangle is
so we know that 4²+b²=5²
so that would simplify as 16+b=25
so x=25-16
which is 9
so therefore we can conclude that

Answer:
1/27000
Step-by-step explanation:
= 3^-3 × 10^-3
= 1/3³ × 1/10³
= 1/27 × 1/1000
= 1/27000

Answer:
9 days
Step-by-step explanation:
100 + 50= 150
100 scouts= 12 days
×2 ÷2
200 scouts= 6 days
Midpoint of 100 scouts and 200 scouts= 150
Midpoint of 12 days and 6 days= 9 days
