Answer:
it is 26 give me branliest
Answer:
Honestly im not sure
Step-by-step explanation:
5.2°C = (273 + 5.2)k = 278.2k
Change in temperature = 368k -278.2= 89.8k
q (heat energy) = MCp∆T
When Cp of water =1046J
q = 7.59 g × 1046J × 89.8k
= 712, 934.772Jgk-1 = 713kJgk
When Cp of water =250cal
q = 7.59 g × 250 × 89.8k = 170kCalk
Answer:
Option A) 1
Step-by-step explanation:
we know that
The solution of the nonlinear system of equations is the intersection point both graphs
In this problem the intersection point is (-2,-1)
therefore
The system of equations has only one solution
I believe it’s y=2x-1 (A)
