Answer:
9d+3
Step-by-step explanation:
Distribute the Negative Sign:
=6d+5+−1(2−3d)
=6d+5+(−1)(2)+−1(−3d)
=6d+5+−2+3d
Combine Like Terms:
=6d+5+−2+3d
=(6d+3d)+(5+−2)
=9d+3
Answer:
Step-by-step explanation:
Answer is 
Explanation:
When we are asked to arrange the polynomial in descending order of the powers, also if there is more than one variable, then we need to add all the powers of the variables and then arrange them.
So here in the question, we have to arrange in descending order for the powers of variable x, so we will take the highest order of x first and then arrange in the descending order, as follows:

Answer:
Yes, it is a function
Step-by-step explanation:
It is a function because for every y value there is a different x value. We can also use the vertical line test to see if there are two points on the same line.
4.70, all the others can be simplified to 4.07 by taking away the zeroes after the 7 because they are not significant, The one before the 7 stays because it is significant as it is holding the tenths place value.
