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
Answer:
3) yes, it is in the shaded region
4) no, it lies on a less-than line
5) yes, it lies on a greater-than-or-equal-to line
6) no, it isnt in the shaded region

Answer:
The answer would be the second plot
Step-by-step explanation:
The frequency table show how many sick patients there are in a single age range. In the first two plots, the total dots between numbers 24, 25, 26, 27, 28, and 29 add up to 3, and the other 2 plots do not, so those are not correct.
When we add up the total of dots from ages 30-34 on the first plot, there are only 4 sick patients. On the second graph, there are 6 total patients in that age range. Therefore, the dot plot that corresponds with the frequency table is the second one.
2x+14=22
Move +14 to the other side. Sign changes from +14 to -14.
2x+14-14=22-14
2x=8
Divide by 2 for both sides.
2x/2=8/2
Cross out 2 and 2 , divide by 2 and becomes: 1*1*x=x
x=4
Answer: x=4
