Answer:
x = 19°
Step-by-step explanation:
Let The angle be "a"
Now according to the question,
⇒ 3 × a = (90° - a) - 14° (Then remove the brackets)
⇒ 3a = 90° - a - 14°
⇒ 3 + a = 76°
⇒ 40° = 76°
⇒ a = 76/4
Now since you got 76/4 you have to make it into simplest form so it'll be :
19/1
Your answer is : a = 19°
Answer:
(-2,4)
Step-by-step explanation:



This implies
.
This means
and
.
Subtract 3 on both sides for first equation:
.
Add 3 on both sides for the second equation:
.
So the pre-image (x,y) is (-2,4) if the image is (1,1).
Let's check:



So the solution has been checked and verified.
X = 8.
We know this since the line in question is vertical, so we automatically know it will be x (vertical lines can only pass through the x axis, because the y axis is already vertical).
Vertical lines will pass through only 1 x-coordinate, but they pass every point on the y-axis, since they infinitely go up and down (which, we already said, is the y-axis).
Answer:
<h2>The range is the simplest measure of variability to compute. The standard deviation can be an effective tool for teachers. The standarddeviation can be useful in analyzing class room test results. A large standarddeviation might tell a teacher the class grades were spead a great distance from the mean.</h2>
