Answer:
A
Step-by-step explanation:
We only need to calculate one of the functions shown. I will be using |x| - 1 because it is the simplist.
|x| makes a V shape and we know it only goes from -1 to 1. And that means it can be A or D. Next we apply the -1 so that it will go down. The only option that fits this is option A.
Answer:
1/6 is your answer :))
Step-by-step explanation:
There is 1 four out of 6 possible numbers = 1/6
y= (-5/2)x - 22
because 5x+2y=12 turns to y=(-5/2)x + 6 and the line parallel to it has to have the same slope so you have to just get the y intercept by plugging in -10 into the equation (-5/2)(-10)+?=3 and ?= -22.
The area equation for a rectangle is length times width. And the area equation for a half (or semi) circle is (1/2) times pi (or 3.14) times the radius squared.
So, you have to add the area of the rectangle and semi-circle together.
Rectangle: A = 18*10 = 180 cm^2
Semi-circle: A = (1/2)*3.14*(18/2)^2 = 127.17 cm^2
Add those together to get 307.17cm^2 or choice C.
5x - 4 -9x + 7
simplify
5x - 9x = -4x
-4 + 7 = 3
Answer: -4x - 3
