Answer:
$ 2.30
Step-by-step explanation:
Given that the sales tax rate 
The cost of the book is $ 12.99.
So, the tax on the book= 8.5% of 12.99

=1.10
So, the sales tax on the book is $ 1.10.
The cost of the video game is $ 39.99.
So, the tax on the book= 8.5% of 39.99

=3.30
So, the sales tax on the book is $ 3.40.
The difference of taxes on both the items = $ 3.40-$ 1.10=$ 2.30
So, the tax on the video game is $ 2.30 more than then tax on the book.
Answer/Step-by-sep explanation:
1. Given:
∆NMK ≅ ∆TRP




a. To complete the congruent statement, thus: ∆MNK ≅ ∆RTP
b. The side that is congruent to
is
. Thus:
≅ 
c. Since
≅
, therefore:

(substitution)
Add 1 to both sides


Divide both sides by 3


2. a. Slope of LK = 
Slope of LM = 
b. ✍️Length of LK is the distance between L(-7, 4) and (-4, 8):






✍️Length of LM is the distance between L(-7, 4) and (-2, 1):





(nearest tenth)
∆KLM is not an isosceles ∆ because it does not has two equal side lengths. This we can see because LK and LM are not equal.
Therefore, Anthony is incorrect. Am isosceles ∆ has two equal sides.
Answer:
a
Step-by-step explanation:
Find the perimeter of the rectangle with points...
W(6,9), X(9,7), Y(3,-2), Z(0,0)
Given:
(x₁,y₁) = (-2,4)
(x₂,y₂) = (0,2)
Determine the slope of the function
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 4) / (0 + 2)
m = -2/2
m = -1
Determine the equation
y - y₁ = m(x - x₁)
y - 4 = -1(x - (-2))
y - 4 = -1 (x + 2)
y - 4 = -x - 2
y = -x - 2 + 4
y = -x + 2
f(x) = -x + 2
The correct answer is first option
