Answer:
3.
Step-by-step explanation:
The scale factor is basically what figure B is divided by.
9 / 3 = 3
3.6 / 3 = 1.2
Answer:
0 / no solutions
Step-by-step explanation:
Rewrite both in terms to the form y = equation.
EQ1: y = 3x + 4 (already in correct form)
EQ2: y = 3x - 6 (subtracting 6 from both sides).
Now suppose there is an intersection, then:
3x + 4 = 3x - 6, subtracting 3x from both sides gives:
4 = -6, which is a contradiction!
Therefore there are 0 / no solutions
3.2

Answer:
AB ≅ AC since triangle ABC is an isosceles triangle.
Step-by-step explanation:
- If angle 1 and angle 2 are equal, then triangle ADE is an isosceles triangle.
- Since line DE is parallel to line BC, then angle 2 is equal to angle 3 and angle 1 is equal to angle 4 (corresponding angles are equal).
- Since angle 3 is equal to angle 2 and angle 4 is equal to angle 1, then angle 3 is equal to angle 4.
- Since angle 3 is equal to angle 4, then triangle ABC is an isosceles triangle that have equal base angles (i.e angle 3 and angle 4).
- The two sides of the isosceles triangle ABC (i.e sides AB and AC) are also equal.
- Hence AB ≅ AC
