Answer: about 79%
Step-by-step explanation:
If you put all numbers from 58.11 to 100.100, the exact median would be 79.055.
3x-4y=18
+3x +3x
-----------------
-4y=3x+18
÷-4 ÷-4
----------------
y=-3/4x-6
x+3y=-7
-x -x
------------
3y=-x-7
÷3 ÷3
--------------
y=-x-7/3
I think but not sure :)
Answer:
4(x - 9)^2 - 17
Step-by-step explanation:
A horizontal shift to the right by 9 changes x^2 to (x - 9)^2.
A vertical shift down by 1 changes - 16 to -17.
Therefore, the new equation is:
4(x - 9)^2 - 17
The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.
To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.
