Two numbers are 10 units away in different directions from their midpoint, m, on a number line. The product of the
numbers is -99.
Which equation can be used to find m, the midpoint of the
two numbers?
(m - 5)(m + 5) = 99
O (m-10)(m + 10) = 99
m2 - 25 = -99
O m- 100 = -99

The equation can be used to find m, the midpoint of the

two numbers is:

Step-by-step explanation:

Two numbers are 10 units away in different directions from their midpoint, m, on a number line.

Then, we can define the two numbers as:

The product of the  numbers is -99. This can be written as:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
