Answer:
2x-5y-20=0
Step-by-step explanation:
2y=-8+4/5x
2y+8-4/5x=0
10y+40-4x=0
5y+20-2x=0
-2x+5y+20=0
2x-5y-20=0
Answer:
1. If x=5, 3*5=15, 15*15=225 + y (3) = 228.
2. If y=4, then 10*4 = 40, 4^2 is 16, so 40 + 16 is 56.
I might be wrong, but the first one you answered, x^2, x= 1/2, I think that is wrong. when something is squared, you don't go, "Oh, well since 1/2 equals 1, that's the answer." The way to figure out something like this is... 1/2 times 1/2, which is .25, or 1/4. Another example: 3^5 . The way to find this out is 3*3*3*3*3 = 243. But you don't go 3*5, because that answer would be 15, which is not correct.
