Answer:
solution: (2, -2)
Step-by-step explanation:
y = 7x - 16,
y = 2(2x - 5)
solving...
7x - 16 = 2*(2x - 5)
7x - 16 = 4x - 10
7x - 4x = 16 - 10
3x = 6
x = 2
y = 7*2 - 16 = 14 - 16 = -2
Answer:
AC
Step-by-step explanation:
First, let's find m∠B and m∠C by solving for x. Since the sum of interior angles in a triangle is 180°, we know that:
60 + 3x - 2 + 2x + 7 = 180
5x + 65 = 180
5x = 115
x = 23° so m∠B = 3(23) - 2 = 67° and m∠C = 2(23) + 7 = 53°. The longest side of a triangle is always opposite to the largest angle of the triangle, and since m∠B is the largest, we know that the side opposite to ∠B is the longest. That side is AC.
