Answer:
163
Step-by-step explanation:
10(10)+9(7) <em>Stubstitute the variables for the values given</em>
100+63 <em>Multiply </em>
163 <em>Add</em>
 
        
             
        
        
        
The x-intercept is what 'x' is when 'y' is equal to 0. So plug in 0 for 'y' and solve for 'x':


Simplify:

Divide 4 to both sides:

So the x-intercept is (4, 0).
The y-intercept is what 'y' is when 'x' is equal to 0. So plug in 0 for 'x' and solve for 'y':


Simplify:

Divide 2 to both sides:

So the y-intercept is (0, 8).

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
