Answer:
A: She found one valid solution and no extraneous solutions.
Step-by-step explanation:
When solving you get x= -(11/3)
Answer:
Upward, x intercept is (2,0) , y intercept is (0,1), axis of symmetry is 2, vertex is (2,0)

Answer: Choice C) $1,444.50</h3>
========================================================
There are two methods to get the answer.
The slightly longer method is to take 7% of the original price to get
7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50
The sales tax is $94.50
Add this onto the original price to get 1,350+94.50 = 1,444.50
----------------------------
A shortcut is to multiply the original price by 1.07
The multiplier 1.07 represents a 7% increase since
- 1 = 100%
- 0.07 = 7%
- 1.07 = 1 + 0.7 = 100% + 7%
So we will have 1.07*1350 = 1,444.50
Answer:
b = 7
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for b
and the exact value
tan30° = 
, thus
tan30° = 
= 
and
= ( cross- multiply )
b = 7
