When the lines are parallel then there is no solution to the system of equations.
This happens because the intersection is the solution. And when there is no intersection then there is no solution.
Answer and Step-by-step explanation: The described right triangle is in the attachment.
As it is shown, AC is the hypotenuse and BC and AB are the sides, so use Pytagorean Theorem to find the unknown measure:
AC² = AB² + BC²




AB = 5.4
Then, right triangle ABC measures:
AB = 5.4cm
BC = 4.5cm
AC = 7cm
Answer:
Step-by-step explanation:
Multiply $120 (cost of haircut) X .18 (18% in decimal form) to get the tip amt.
120 X .18 = 21.60
Now add $120 (haircut) + 21.60 (tip) together to get the total amt. she paid.
120 + 21.60 = $131.60
Carla gave her stylist $131.60 total
