Answer:
Step-by-step explanation:
There are no factors outside the parentheses that need to be distributed, so the parentheses can be simply dropped:
6 -2x +15 -3x
The terms can be rearranged to put like terms next to each other:
-2x -3x +6 +15
and the like terms can be combined.
-5x +21 . . . . simplified expression
__
Put the value of x where x is, then do the arithmetic.
-5(-0.2) +21 = 1 +21 = 22
Which of the sets of ordered pairs represents a function? (4 points) A = {(−4, 5), (1, −1), (2, −2), (2, 3)} B = {(2, 2), (3, −2

A function will not have any repeating x values....it can have repeating y values, just not the x ones
(-4,5),(-1,1),(2,-2),(2,3)
this is not a function because it has 2 sets of points that has x as 2...so it has repeating x values
(2,2),(3,-2),(9,3),(9,-3)
this is not a function because it has 2 sets of points that has an x value of 9...so it also has repeating x values
so both of these are not functions.....neither of them
Answer:
x= -2
Step-by-step explanation:
Step 1. In order to find the zeros of the function, we must factor it.
Step 2. To factor this, we have to find two numbers that multiply to 4 and add to 4 which is 2 ( 2*2=4 and 2+2=4)
step 3. 0=(x+2)(x+2)
Step 4 make (x+2) equal to zero and solve which gives us -2, so -2 =x.
10 of the power of 3 equals 1,000. 10•10•10 = 1000
