The correct statements about similarity of triangles are A, B, and C.
<h3>
What is a similar triangle?</h3>
Similar triangles are triangles that have the same shape, but their sizes may vary. This type of triangles are said to have congruent angles and corresponding sides.
From the given figure,
- triangle ABC is a right triangle and triangle BDC is also a right triangle
- triangle ABC is a right triangle and triangle ADB is also a right triangle
- angle ABD is 45 and angle BCD is also 45 degrees.
Thus, the correct statements about similarity of triangles are A, B, and C.

Answer:
The indifference point is 140 minutes.
Step-by-step explanation:
Giving the following information:
Plan A costs $ 25 plus an additional $0.10 for each minute of calls.
Plan B costs $18 plus an additional $0.15 for each minute of calls.
<u>First, we need to establish the total cost formula for each plan:</u>
<u />
Plan A= 25 + 0.1*x
Plan B= 18 + 0.15*x
x= number of minutes
<u>Now, to calculate the indifference point, we equal both formulas and isolate x:</u>
25 + 0.1x = 18 + 0.15x
7 = 0.05x
140=x
The indifference point is 140 minutes.
<u>Prove:</u>
Plan A= 25 + 0.1*140= $39
Plan B= 18 + 0.15*140= $39
Answer:
After 10 weeks, Susan will have $295 and CiCi will have $259.
Step-by-step explanation:
Susan: y= 65+23x
CiCi: y = 119+14x
65+23(6)=203
119+14(6)=203
After 6 weeks, Susan and CiCi will both have $203 in their accounts.
65+23(10)=295
119+(14)(10)=259
Therefore, After 10 weeks, Susan will have $295 and CiCi will have $259.

Step-by-step explanation:
j + (-3) = 9
j = 12
Answer:
Step-by-step explanation:
It is vital to first find the gradient/ slope between the points
let us use the point (6,1) to find the value of c
y=mx+c
1=1(6)+c
1-6=c
∴c=-5
the equation is given by
y=x-5
