Answer:
4y-8x=12
Step-by-step explanation:
because in a infinitely many solutions then it should proportional to the first equation
Normally, I would say that PC (with the line over it) would mean point P to point C, but I do not see point P on the image. Is that the part you don't understand? There being no P?
So, multiply the terms with equal exponents by multiplying their bases.
So, (2^7 × 4^7)^3 becomes [(2×4)^7]^3
Then, just multiply the numbers.
(8^7)^3
Then, simplify the expression by multiplying the exponents. So, the answer should be 8^21 or eight to the 21st power.

Answer:
first one: B and C
Second one: x=12, y=10 so the answer is B.
Step-by-step explanation:
First one: Irrational numbers are any numbers that go on forever in the decimal without ever repeating. Any square roots of numbers that aren't perfectly square, such as 4 and 9, are irrational. And anything with pi, or
, is always irrational.
Second one: 144 and 100 are perfect squares, meaning it can be created by multiplying the same number by itself, in this case 12 and 10. Subtract those and you get 2.
