Answer:
x<3
Step-by-step explanation:
12-8x+9>3x-12
21-8x>3x-12
-8x-3x>-12-21
-11x>-33
x<3
Even
means ends with 0,2,4,6,8
adds to 10
the last number cannot be 0 because the first cannot be add to 10
it can be
8xx2
6xx4
4xx6
8xx2
where x is any whole number you want
(12 + 3) + 32 = 12 + (3 + 32)
Associative property of addition: if you have to sum three or more terms, you can group them as you like.
14(1/14) = 1
Multiplicative inverse: a number multiplied by its inverse is 1
27 + 0 = 27
Identity element of addition. If you sum any number with zero, the result is the number you started with.
11(4y – 9) = 44y - 99
Distributive property of addition: if you have to multiply a whole sum/subtraction by a number, it is the same as multiplying each term in the sum/subtraction by that number.
Answer:
This is easy -- it's just a list of steps. At this level, the problems are pretty simple.
Let's just do one, then I'll write out the list of steps for you.
Find the inverse of f( x ) = -( 1 / 3 )x + 1
STEP 1: Stick a "y" in for the "f(x)" guy:
y = -( 1 / 3 )x + 1
STEP 2: Switch the x and y
( because every (x, y) has a (y, x) partner! ):
x = -( 1 / 3 )y + 1
STEP 3: Solve for y:
x = -( 1 / 3 )y + 1 ... multiply by 3 to ditch the fraction ... 3x = -y + 3 ... ditch the +3 ... subtract 3 from both sides ... 3x - 3 = -y ... multiply by -1 ... -3x + 3 = y ... y = -3x + 3
STEP 4: Stick in the inverse notation, f^( -1 )( x )
f^( -1 )( x ) = -3x + 3
Step-by-step explanation:
X is greater than or equal to four
