Answer:

X = 11

X = 7

Step-by-step explanation:

Part 1:

The measure of an inscribed angle is half the measure of an intercepted arc. So 1/2 mCE = m∠CDE

158 ÷ 2 = 79

You need to find x so you're going to set your equation of (8x - 9) = 79

Then you're going to add 9 to both sides to get 8x = 88

Divide both sides by 8 to get x = 11

Part 2:

We know that WY is 180 because it's a semicircle. Using this and the knowledge that ∠WXY is half the measure of the intercepted arc (180), we know that our equation should be (13x - 1) = 90

add 1 to both sides and our equation is (13x = 91)

Divide both sides by 13 and...

x = 7

Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.
zalisa [80]
<h3>Answer: C) 4</h3>

All points on the blue curve f(x) are shifted up 4 units to get corresponding points on the red curve g(x). For example, the point (0,-3) moves up 4 units to (0,1).

g(x) = f(x)+k

g(x) = f(x)+4

A price is decreased from £800 to £640. Calculate the percentage change.
Anni [7]
<span>There is a decrease of 20% from ÂŁ800 to ÂŁ640.

    A change from 800 to 640 represents a negative change (decrease) of -20% Using the formula :

   Percent change = [(800 - 640) / 800] x 100 = -20 % (decrease)

       800 is the old value and 640 is the new value. In this case we have a negative change (decrease) of -20 percent because the new value is smaller than the old value.</span>

Which number between 20 and 28 are prime
ad-work [718]
Prime numbers basically numbers that dont have any numbers that will be multiplied to get to it. So, it would be:
 23
-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-
All the other numbers in between can be divided by something and not become a decimal. Other than 23, it can be divided by anything without becoming a decimal.
