First you need to multiply by a factor that will givr you the same value in one of the x or y value.
(6x-12y=24)1
+(-x-6y=4)-2
6x-12y=24
=2x+12y=-8
8x=16÷8
x=2
now that you have x, substitute x by 2 in one of the eqauations
-2-6y=4
+2. +2
=-6y=6
÷-6. ÷-6
y=-1
since alie ate 15 gram and there are 12 grams in every 8.
what i did, I made a table that looks like
once you make a table that looks like this, in this kind of situations.
multiply across ( yellow ones)
and then divide by the green one
and then you'll get the answer
slope=(-16-5)/(-8-18)=21/26
The following is the rest of the question:
------------------------------------------------------
Mikey's results showed that although both mice gained weight over the
month, mouse 2 gained more weight than mouse 1.Which graph below best
shows these results?
The complete figure is attached
=========================================================
Solution:
---------------
Graph (1)⇒⇒⇒ mouse 2 has constant weight and mouse 1 gained weight
Graph (3)⇒⇒⇒ mouse 2 has did not gain weight and mouse 1 gained weight
∴ Graph (1) and (3) are incorrect because both mice gained weight .
Graph (4) is incorrect because mouse 2 gained more weight than mouse 1
So, the correct answer is graph (2)
Answer:
B
Step-by-step explanation:
4(7-3)=16
7-3=4
4x4=16
