Answer:
x = -1.32
Step-by-step explanation:
I expect '--' means equals to '=' in your question
4(10x+6)--10(9x+9)
4(10x+6)=10(9x+9)
40x +24 = 90x +90
40x - 90x = 90 - 24
-50x = 66
x = -66/50
x = -1.32

Answer:
Note: to write the domain in interval notation, you'd write [-4,5]
if you need the domain in set-builder notation, then you'd write
------------------------------------------------------------------------------
Explanation:
The domain is the set of possible x input values. Look at the left most point (-4,-1). The x coordinate here is x = -4. This is the smallest x value allowed. The largest x value allowed is x = 5 for similar reasons, but on the other side of the graph.
So that's how I got
(x is between -4 and 5; inclusive of both endpoints)
Writing [-4,5] for interval notation tells us that we have an interval from -4 to 5 and we include both endpoints. The square brackets mean "include endpoint"
Writing
is the set-builder notation way of expressing the domain. The
portion means "x is a real number"
42 divided by 3 is 14
42 over 3 is a whole number of 14
