Answer:
ab = 1
Step-by-step explanation:
A Reciprocal of a number is a number which when multiplied by the original number yields the multiplicative number, 1.
So the reciprocal of x would be x⁻¹ or ¹⁄ₓ
The information we are given states that the sum of the two non-zero numbers a and b equals the sum of their reciprocals.
So we can write this into an equation and solve,
(See image)
Once we solve, we get the equation (ab-1)(a+b) = 0
We are given info that a+b≠0
So for the above equation to be true, ab-1 has to equal 0
For <em>this</em> to be true, the product ab must equal 1

Answer:
- C = (5/9)(F -32)
- 50°F ⇒ 10°C
Step-by-step explanation:
Starting with the formula for degrees Fahrenheit, we can solve for degrees Celsius.
F = 32 +9/5C
F -32 = (9/5)C . . . . . subtract 32
(5/9)(F -32) = C . . . . multiply by the inverse of the coefficient of C
The formula for Celsius temperature from Fahrenheit temperature is ...
C = (5/9)(F -32)
__
For F = 50, the corresponding Celsius temperature is ...
C = (5/9)(50 -32) = (5/9)(18) = 10 . . . degrees Celsius

Answer:
y = 2/3x + 3
Step-by-step explanation:
In order to put it in slope intercept form (y = mx + b), y needs to be isolated.
Add 2x to both sides:
-2x + 3y = 9
3y = 2x + 9
Then, divide both sides of the equation by 3.
3y = 2x + 9
y = 2/3x + 3 is the equation in slope intercept form
