Y= 2x-4
4x+Y=2
4x+2x-4=2
6x-4=2
+4=+4
6x=6
6/6X = 6/6 X=1
Y=2X-4
2(1)-4
Y=-2
For this case we have the following polynomial:

Rewriting we have:

Then, completing squares we have:

Rewriting:

Then, the solutions are:
Answer:
Answer:
10400km
Step-by-step explanation:
We know that the scale on a map is 1cm for every 400km. So to find the actual distance for 26cm on the map, we take 26 multiplied by 400km. This gives 10400km.
Answer:

Step-by-step explanation:

Answer:
427,350
Step-by-step explanation:
so you do 7.25×13=94.25
and then you do 94.25%×220,000=207,350
So you can now do 207,250+220,000 (which) =427,350
