Let x be larger integer so x-3 is the smaller
so x^2+ x-3 = 87
x^2 +x -90=0 and factor
(x-9)(x+10)=0
x=9 or x=-10 but x must be positive
so x=9 and smaller number is 6
You would probably need a little larger sample of people because not all people wear corrective lenses. In almost any other survey, this would be a scientist’s dream, but in this one, you’d need it to be a little bigger.
The linear equation that represent the left balance of sanjaya’s y after visiting x number of days is:
y = 10x + 500.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
From the data given, we have that:
- The y-intercept is of 500.
Hence the balance is given as follows:
y = 10x + 500.

The missing number is 6. 3.6-.65 = 2.95
3.6 - 2.95 = .65
Hope it helps ;)))
