Answer:

1 \cdot 10^7 +2 \cdot 10^6+ 4 \cdot 10^5+ 3 \cdot 10^4

Step-by-step explanation:

write 12,430,000 in expanded form using exponents

First we write the expanded form of each digit

1 is in ten millions place , 1 times 10,000,000

2 is in millions place , 2 times 1,000,000

4 is in hundred thousands place , 4 times 100,000

3 is in ten thousands place , 3 times 10,000

Now we write it in expanded form

1 \cdot 10,000,000 +2 \cdot 1,000,000 + 4 \cdot 100,000+ 3 \cdot 10,000

1 \cdot 10^7 +2 \cdot 10^6+ 4 \cdot 10^5+ 3 \cdot 10^4

B) Which one of the following points lies on the line 2y = 5x - 3?
sergeinik [125]
Given the equation 2y = 5x - 3:

A way to find out which of the ordered pair options lie on the line is to substitute their coordinates into the equation.


A) (2, 5)
2y = 5x - 3
2(5) = 5(2) - 3
10 = 10 - 3
10 = 7 (False statement). this means that (2, 5) is not a solution to the given equation.

B) (6, 3)
2y = 5x - 3
2(3) = 5(6) - 3
6 = 30 - 3
6 = 27 (False statement). this means that (6, 3) is not a solution to the given equation.

C) (3, -6)
2y = 5x - 3
2(-6) = 5(3) - 3
-12 = 15 - 3
-12 = 12 (False statement). this means that (3, -6) is not a solution to the given equation.

D) (3, 6)
2y = 5x - 3
2(6) = 5(3) -3
12 = 15 - 3
12 = 12 (True statement). This means that (3, 6) IS a solution to the given equation.

E) (2, -5)
2y = 5x - 3
2(-5) = 5(2) - 3
-10 = 10 - 3
-10 = 7 (False statement). this means that (2, -5) is not a solution to the given equation.

Therefore, the correct answer is Option D: (3, 6).

Factorise <br> a) 4p²-81<br> b) x²-13x+36
taurus [48]

Answer:

A = (2p + 9) (2p - 9)

B = (x - 9) (x - 4)

Step-by-step explanation:

For A : Rewrite 4p^2 as (2p)^2.

(2p)^2−81

Rewrite 81 as 9^2.

(2p)^2−9^2

Since both terms are perfect squares, factor using the difference of squares formula, a^2 − b^2 = ( a + b ) ( a − b ) where a = 2p and b = 9 .

(2p + 9) (2p − 9)

For B : Consider the form x^2 + bx + c . Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 36 and whose sum is − 13 .

-9, -4

(x - 9) (x - 4)

I hope this helps.
