The equation of the line will be (assuming the y-intercept equal to zero):

y = 2.5*x

<h3>What is Tahila's mistake?</h3>

We know that we have a linear equation of the form:

y = a*x + b

Such that we know that the line passes through (-3, -7.5), notice that the proposed equation is:

y = 0.5*x

If you evaluate that in -3, you get:

y = 0.5*-3 = -1.5

So this line does not pass through (-3, -7.5).

If we assume that b = 0 in the linear equation, then we can find the value of a as:

-7.5  =  a*-3

a = 7.5/3 = 2.5

Then the linear equation is:

y = 2.5*x

The length of a rectangle is twice it’s width.The perimeter of the rectangle in 162 inches.How long is the rectangle?
Artist 52 [7]
The perimeter of a rectangle is all sides added  up, so length + length + width + width.

L = length

W = width

then the perimeter is L+L+W+W, or 2L + 2W, or 2(L+W).

\bf \textit{perimeter of a rectangle}\\\\&#10;P=2(L+W)~~&#10;\begin{cases}&#10;P=162\\&#10;L=\stackrel{\textit{twice W}}{2W}&#10;\end{cases}\implies 162=2(2W+W)&#10;\\\\\\&#10;\cfrac{162}{2}=3W\implies 81=3W\implies \cfrac{81}{3}=W\implies 27=W

what's the length?  well, is just 2(27).

Answer:

Possible Outcomes = {January , February, March, April,May, June, July, August, September , October , November ,December}

Explanation:

In probability The possible outcomes is a possible result of an experiment which we are performing. Each possible outcome is unique for a particular experiment

Now in this problem we are performing the experiment of putting the names of months in bag

Total months are 12

which are January , February, March, April,May, June, July, August, September , October , November and December

Now

Possible Outcomes = {January , February, March, April,May, June, July, August, September , October , November ,December}

So these are the possible results which can occur in our experiment that which ever we will pick the answer will be one of these 12 names

Answer:

options 1, 3, and 6.

Step-by-step explanation:

on the diagram, ∠2 is in the area of line EA and EG. If you are reading it by letters, ∠GEA is equal to ∠2 because they are in the same area. The last option (6) being ∠AEG, the middle angle is E which is the same as ∠GEA and ∠2.

hope this helps!! :))
