Answer: One solution
Step-by-step explanation:
When the lines intersect in one spot, there's one solution. The lines have different slopes, so there's only one solution.
Answer:
$6
x=7
AC=3x+3 AB=-1+2x and BC=11
AC = AB + BC
ALL THE STEPS:
3 X + 3 = - 1 + 2 X + 11
3 X + 3 = 2 X + 10
3 X + ( - 2 X ) + 3 = 2 X + ( - 2 X ) + 10
X + 3 = 10
X + 3 + ( - 3 ) = 10 + ( - 3 )
X = 7
11
Use the cosine law:
We have:
Substitute:
