I believe your answer is -220w-22
2-3(2w+1)=7w-3(7+w)
+7w -7w
2-3(9w+1)=-3(7+w)
+w -w
2-3(10w+1)=-3(7)
2-3(10w+1)=-21
-1(10w+1=-21
-21 +21
-22(10w+1)
-220w-22
Both claims are false. In fact,
and
are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that

So, it doesn't matter if
is positive or negative: the multiplication of one number and its inverse will always be 1: for example,

Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:
So, the multiplication of two negative numbers is a positive number.
Answer:
Width is 10 1/2 inches and the length = 21 inches.
Step-by-step explanation:
Let the width be x then the length us 2x inches.
Perimeter = 2x + 2(2x) = 63
6x = 63
x = 10 1/2 inches.
We have been given that the number of species of coastal dune plants in Australia decreases as the latitude, in °s, increases.
Further we know that there are 34 species at 11°s and 26 species at 44°s.
We can express the given information at two ordered pairs as shown below:

Let us find slope of the line through these points:

Therefore, we can write the equation of line in slope intercept form as:

Where b is the y intercept, and we can find its value using one of the two points.

Therefore, the required equation of the linear function is:

I think it B or D I hope i don’t get it wrong
