We know that there are (4^9)^5 ⋅ 4^0 at the library, so we just need to simplify this to get the answer.
(4^9)^5 ⋅ 4^0
=(4^9)^5×1
=(4^9)^5
=4^9×5
=4^45. As a result, the total number of books at the library is 4^45 books at the library or B is the final answer. Hope it help!

What values of x and y satisfy the system of equations {10x+3y=−5−5x−4y=10? (0,−53) (25,−3) (−2,0) (12,−103)

Kitty [74]

Answer:

The solution of the equation

( 0.4 ,-3)

Step-by-step explanation:

Explanation:-

Step(i):-

Given system of equations

10 x+3 y = −5 ...(i)

- 5 x - 4 y = 10 ...(ii)

Multiply (i) with '5'

10 × 5 x + 3×5 y = - 25

50 x + 15 y = 25 ...(iii)

Multiply (ii) with '10'

-5 × 10 x - 4×1 0 y = 100

- 50 x - 40 y =100 ...(iv)

Step(ii):-

Solving (iii) and (iv)

50 x + 15 y =- 25

- 50 x - 40 y =100

- 25 y = 75

Dividing ' - 25' on both sides, we get

y = -3

substitute y = -3 in equation (i) , we get

10 x+3 y = −5

10 x - 9 = - 5

10 x = -5 + 9

$x = \frac{4}{10}$

x = 0.4

Final answer:-

The solution of the equation ( 0.4 ,-3)
