The shirt is $18 before taxes are applied. 
10% of 20 is 2. 20-2=18. 
After taxes are applied the shirt is $19.53.
8.5% of 18 is 1.53. 1.53 + 18 = $19.53

Multiply 20x.01 which equals 2. subtract that from 20 wich gives you 18
$18
multiply 18x.085 which equals 1.53. add that to 18 and that is your answer
$19.53 after

The equation of the line passing through the points (−10, 0) and (−8, 20) can be expressed as y = mx + b. Give the value of b.
weeeeeb [17]

Given are the two points (-10,0) and (-8,20), and equation of the line as y=mx+b.

We can plug the given values in the equation as follows :-

0 = -10m + b .........equation(1)

20 = -8m + b .........equation(2)

Subtracting equation(1) from equation(2)

20 - 0 = (-8m + b) - (-10m + b)

20 = -8m + b + 10m - b

20 = 10m - 8m

20 = 2m

m = 10

Plugging m=10 in the equation(1)

0 = -10(10) + b

0 = -100 + b

b = 100

So final answer is b = 100.

The hinge theorem states that if two triangles have equivalent side lengths but different angles, the triangle with the larger angle is going to have a longer opposing side.

UVT < UTS < STR

That means that VU < US < SR, due to the hinge theorem

Hey can you please help me posted picture of question

If you observe the graph, the graph is touching the x-axis at the point x=-1 and is turning away. 

This means, the graph as an even multiplicity at x=-1. So the two roots of the given polynomial are x = -1 and x = -1. Thus, the two factors of the polynomial are (x+1) and (x+1)

Product of the factors is equal to the polynomial. So the given polynomial will be (x+1)(x+1).

Therefore, the answer to this question is option C
