right-handThe triangles are similar if, the ratios of their sides are equal


On the left-hand side

and in the right-hand side, we have

The left-hand side equals the right-hand side; therefore, the triangles are similar.
Answer:
b=41
Step-by-step explanation:
180=19v-41+(180-(20v+39))+17v
v=5
180=19v-41+b+17v
180=19(5)-41+b+17(5)
b=41

Answer:
The answer is Tonya's phone had the greater initial trade-in value.
Leo's phone decreases at an average rate slower than the trade in value of Tonya's phone.
Step-by-step explanation:
Given
Tonya

Leo




Solving (a): The phone with greater initial value
The initial value is when x = 0. So, we have:




From Leo's table

By comparison;

i.e.

<em>So: Tonya's had the greater initial trade-in value</em>
Solving (b): The phone with lesser rate
An exponential function is:

Where:

For Tonya

For Leo, we have:


So, the equation becomes:

and 
Solving
, we have:



becomes

Divide both sides by 480

Take square roots

-- Leo's rate
By comparison; Leo's rate is slower i.e. 0.87 < 0.88
