Answer:
A. Exactly one solution
Step-by-step explanation:
Solve the system of equations.
y = x + 1
y = 2x - 5
Substitute one equation into the other.
y = 2x - 5
x + 1 = 2x - 5
Subtract 2x from both sides.
-x + 1 = -5
Subtract 1 from both sides.
-x = -6
Multiply both sides by -1.
x = 6
Put it back into the other equation.
y = x + 1
y = 6 + 1
Add.
y = 7
The solution is (6, 7). Since the equations aren't equal, there are not infinitely many solutions, but since there is a solution found, we can determine that there is exactly one solution.
Answer:
Step-by-step explanation:
3^2+x^2=6^2
9+x=36
36-9=27
sqrt 27
x=5.2
Answer:
If M is the midpoint, then LM = MN
3x - 2= 2x +1
x = 3
So LM = 3x - 2 = 9 -2 = 7
LM = 7
Answer: 2 years
Step-by-step explanation:
If Interest= Principal x rate x time/100; then time is (100 × Interest)/(Principal × Rate)
From the question, old Principal is 5600, new principal =6720, the difference is the interest accrued.
Interest = 6720 - 5600 = Rs 1120
Rate = 8% = 8 ÷ 100 = 0.08
Time = x
Then, slot the values into the formula
Time= 100 x 1120 / 6720 x 8
= 112000/53760
=2.08
Time= 2years
I hope this helps
