the sum of two numbers is 34. the sum of the smaller and 6 times the larger is 159. frind the numbers​

Answers

Answer 1
Answer:

Answer:

9,25

Step-by-step explanation:

Let the numbers be x, y

x + y = 34

x = 34 - y   -----------(i)

x + 6y = 159  --------(ii)

substitute x value in (ii)

34 - y +6y = 159

34 + 5y = 159

5y = 159 - 34

5y = 125

y = 125/5

y= 25

Substitute y value in equation (i)

x = 34 -25

x = 9

Please Help: Determine which ordered pair is a solution of y = x^2 - 2. A) -2,6
B) 5, 21
C) -1, -1
D) -5, 24

Answers

The answer is C
The term "ordered pairs" refers to graphing and so it will always be in the order of x,y....x first and then y, ALWAYS, so this tells you that in every potential answer given, that the first number IS x and then
to solve for y (the second number) you must do as the equation states and square x,(the first number in the ordered pair you are testing), (squaring means to times it by itself) and then subtract 2, the answer to that, will give you the solution for y.....so......so try this out for all of the above listed potentially correct answers, only ONE will work out properly 
Important: to do the equation, you must remember that a negative times a negative ALWAYS equals a positive....so
-1 * -1 = 1.....then the last step, subtracting 2 (-2)
1 -2 = -1......thus C : -1, -1.... is the only possible answer

Whats 7630918 to the nearest 1000

Answers

7630918 rounded to the nearest 1000 is 7,631,000
The nearest 100 is the third digit in a number to the left of 0.  In this case, that number is 9.  If the number after 9 was greater than 4, the 9 would be rounded up.  However, because 1 is less than 5, the 9 remains the same. 

The answer is 9630900.
