Answer:
(4,1), (-4,1), (4,6), (-4,6)
Step-by-step explanation:
Here can be identified two points with the same 'y' value: (4,1), (-4,1)
it means that there is a line passing by y=1
Same for (4,6), (-4,6): it means that there is a line passing by y=6
Now find the distance between two points in both cases
Answer:
angle 4
Step-by-step explanation:
5 of Anne’s pens still have ink. Since 23 of the 28 pens ran out, 5 pens are still good to write with.
Hope this helped!
1) -3(5x+2y=-3)⇒ -15x-6y=9
⇒ -9x=27
2(3x+3y=9)⇒ 6x+6y=18
2) -9x/-9=27/-9 ⇒ x=-3
3) 3(-3)+3y=9⇒ -9+9+3y=9+9⇒ 3y/3=18/3⇒ y=6
Answer: (-3,6)
Reasoning:
Step 1) In order to eliminate, first I had to multiple the first equation by -3 and the second by 2 so that when combining the equations y would cancel each other out so that I could solve for x. <em>Note: There are many combinations as to how you could multiple the equations so that either the x or y would cancel out.
</em>
Step 2) Once y is eliminated, solve for x.
Step 3) Now plug x back into one of the original equations and solve for y. <em>Note: Plug x back into one of the original equations, not the equations that were changed by multiplication,</em>
Answer: 288, 576, 1152
Step-by-step explanation: What you do here is that you multiply every number by two. You start by doing 18 times 2, which equals 36. Then you do 36 times 2, which equals 72. You keep on doing this until you get the answers needed.
Hope this helped!! :)
