Mathematics
1 answer:
lions [1.4K]3 years ago
7 0

Answer:

Ok so here are the simple rules of doing it (very easy) cause I’m not doing it all so . when multiplying a power with The same base keep the base but add the exponents. Dividing, keep the base (if their the same if not then its already simplified same with multiplication) but SUBTRACT the exponents. Also keep the parenthesis if it’s a negative number base.

I’ll do a few.

11) a^10.           11b) 5^4

12) (-2)^2.        

13) 10^2.          13b) s^6

14) -4s^5(t^6) <- [Im not sure of this one)

15) x^3(y^3)

−5x+2y=9<br> y=7x<br> ​x=<br> y=
Serhud [2]

- 5x+2y=9 \\ y=7x

We know that y=7x, so we just need tu put it into the 1st equation

- 5x + 2 \times 7x = 9 \\  - 5x + 14x = 9 \\ 9x = 9 | \div 9 \\ 9x \div 9 = 9 \div 9 \\ x = 1

So we found x. Now we can find y

y = 7 \times 1 \\ y = 7

Answer:

x=1, y=7; or (1;7)
