Answer:
(11, 13)
Step-by-step explanation:
First Equation: x+y=24
Second Equation: y=x+2
x + (x + 2) = 24
2x + 2 - 2 = 24 - 2
2x/2 = 22/2
x = 11
y = (11) + 2
y = 13
Therefore, the solution to the system is (11, 13)
Answer:
Step-by-step explanation
just plug in 0 for z so it would change to -2<6
Answer:
9
Step-by-step explanation:
a² + b² = c^2
12^2 + b^2 = 15^2
144 + b^ = 225
225 - 144= 81
b^2 = 81
square root both sides
b = 9
Answer: B
