I will do it step by step
(3xy^-5)^3= 27x^3y^-15
(x^-2y^2)^-4= x^8y-8
So the fraction is (27x^3y^-15)/ x^8 y^8= 27 x^-5y^-7
and the whole thing to power of -2 equals to x^10y^14/ 729
answer is A

Solve this linear system. 2.4 = 0.3 x + 0.4y 5x = 2 + 6y
hammer [34]
\left \{ {{2.4 = .3x + .4y} \atop {5x = 2 + 6y}} \right.

5x = 2 + 6y
Divide both sides by 5
x = 6/5y + 2/5

Input in the other equation.

2.4 = .3(6/5y + 2/5) + .4y
2.4 = .36y + .12 + .4y
2.4 = .76y + .12
Subtract .12 from both sides.
2.28 = .76y
Divide both sides by .76
3 = y

x = 6/5(3) + 2/5
x = 18/5 + 2/5
x = 20/5 = 4

From a standard deck of cards, your first draw is a black card. You replace the card, and the second draw is a diamond. Which TH
ladessa [460]
A, B, D

A: because there are two colour types in a deck of cards, so it’s 1/2 probability of getting a black one.

B: because there a four suits in a deck of cards, so the probability of getting a diamond is 1/4

D: because when calculating compound events we multiply the two probabilities,
so 1/2 x 1/4 = 1/8

Given the function G(r)=8r +4 what does G(8)=?
Marianna [84]
Hi there! The answer is 68.

If we want to find G(8), we must plug in r = 8 into the equation.

g(8) = 8 \times 8 + 4
Multiply first

g(8) = 64 + 4
Now add

g(8) = 68
Hence, the answer is G(8) = 68.

~ Hope this helps you!
