pantera1 [17]3 years ago
4 0

Answer:

10

Step-by-step explanation:

By using intersecting chord theorem:

NH.HT=MH.HY

(x+20)*8=12*20

x+20=12*20/8

x+20=240/8

x+20=30

x=30-20

x=10

What is the equation of the line represented by the table of values?
vredina [299]

Answer: (C) y= x − 2

Explanation:

y=x-2 is the choice that satisfies all the points in the table. This can be verified case by case:

y=x-2

(-3,-5): -5 = -3 -3

(-1,-3): -3 = -1 - 2

(1,-1): -1 = 1 - 2

(3, 1): 1 = x - 2

(5,3): 3 = 5 - 3

Which expression can be used to find the price of a $400 telescope after a 32% markup? Select all that apply.
elena-s [515]
<h3>There are 2 answers: choice C, choice D</h3>

====================================================

Explanation:

32% = 32/100 = 0.32

32% of 400 = 0.32*400 = 400(0.32), which adds onto the original 400 to get 400+400(0.32). This is why choice D is one of the answers.

We can factor out the GCF 400 to go from 400+400(0.32) to 400(1+0.32) which then simplifies to 400(1.32) or just 400*1.32. This shows choice C is the other answer. Using a calculator,

400+400(0.32) = 400 + 128 = 528

400*1.32 = 528

meaning that 400+400(0.32) = 400*1.32

The other answer choices result in other values, showing that they aren't equivalent to 528.

If tv =74 and wv = 4x + 1, solve for x
barxatty [35]

Answer: x equals 9

Step-by-step explanation: The figure in the question is a Rhombus and one of the properties of a rhombus states that “the diagonals bisect each other.”

This means line SU bisects line TV into two equal parts at point W. This also means that line WV is half of line TV. If line TV equals 74 and line WV equals 4x + 1, then we have the following;

(4x + 1) x 2 = 74

4x + 1 = 74/2

4x + 1 = 37

Subtract 1 from both sides of the equation

4x = 36

Divide both sides of the equation by 4

x = 9.
