Answer:
6.743*10^7
Step-by-step explanation:
Given data
The number is 67, 430,000
Let us count from the left the right
counting, we have 7 places to the right before the last digit 6
Hence the number of places is 7
The scientific notation is
=6.743*10^7
<em>Answer:</em>
a = 7 & a = −7
<em>Explanation:</em>
Rewrite the equation as
(x+a)(x−a)=x^2−49
Simplify (x+a)(x−a)
x^2−a^2=x^2−49
Move all terms not containing a to the right side of the equation.
−a^2=−49
Multiply each term in −a^2=−49 by −1
a^2=49
Take the square root of both sides of the equation to eliminate the exponent on the left side.
a=±√49
The complete solution is the result of both the positive and negative portions of the solution.
a=7,−7
Find the solution set for y = 2x + 1, given the replacement set {(-2, -3), (-1, -1), (0, 2), (1, 3), (2, 6)} ...?

We have to plug in the values in the equation:
y = 2 x + 1
- 3 = 2 * ( - 2 ) + 1
- 3 = - 4 + 1
-3 = - 3
-------------------
-1 = - 2 + 1
- 1 = - 1
------------------
3 = 2 * 1 + 1
3 = 2 + 1
3 = 3
------------------
Answer:
The solution set is: { ( -2, 3 ), ( - 1 , 1 ) , ( 1, 3 ) }
