suppose the solution x = 6 increases to x = 9, and the left side of the equation stays the same. How would the right side need to chang if the solution is now x = 9

Answers

Answer 1
Answer:

Answer:

The original solution of the equation

  x=6

Adding 3 on both sides, gives

x+3=6+3

x+3=9

 x=9-3

So,Addition of 3 on left hand side or subtraction of 3 from 9 in right hand side gives solution x=9.
Answer 2
Answer: X = 9 - 3, does this help?

Answers

The ormula of a slope:

m=(y_2-y_1)/(x_2-x_1)

We have the points (5, 2) and (9, y) and the slope m = 3.

Substitute:

(y-2)/(9-5)=3\n\n(y-2)/(4)=3\qquad\text{multiply both sides by 4}\n\ny-2=12\qquad\text{add 2 to both sides}\n\n\boxed{y=14}

What is 0.08333333333 as a whole number.

Answers

0.08333333333 as a whole number is 83.

what is 0.08333333333 as a whole number.

To convert 0.08333333333 to a whole number, we can multiply it by a power of 10 to shift the decimal point to the right until we have a whole number.

0.08333333333 can be written as 83.333333333 (since the 3s continue indefinitely).

However, we want a whole number, so we can round it to the nearest whole number. Rounding 83.333333333 to the nearest whole number gives us 83.

Therefore, 0.08333333333 as a whole number is 83.

Step-by-step explanation:

Use absolute value to express the distance between 10 and -4

Answers

Absolute value does not include direction, therefore, does not have a negative sign. Always positive.

The distance between 10 and -4 is 14.

I showed why in the attachment below. 

So, since we do not include the sign, your final answer is 14.

Final answer: 14

If x^(2) - 2 = 2^(2/3) + 2(-2/3) prove that x = 2^(1/3)+2^(-1/3)

Answers

Step-by-step explanation:

x² - 2 = 2^(2/3) + 2^(-2/3)

x² = 2^(2/3) + 2 + 2^(-2/3)

x² = (2^(1/3))² + 2 × 2^(1/3) × 2^(-1/3) +

(2^(-1/3))² (It is in the form of a²+2ab+b²)

x² = (2^(1/3) + 2^(-1/3))²

x = 2^(1/3) + 2^(-1/3)
