We are asked to solve the x-coordinates of the points that divide AB into a 3:4 ratio. Luckily, we are given with a formula in solving the X-intercept and it is x = (x2-x1)+x1. We are also given with two points such as the following:
A (-4, -10)
B (-11,-7)
Then we x1 = -4 and x2 = 11, substitute this in the given formula:
y = (11 - (-4))+( -4)
y = (11+4) -4
y = 15 -4
y =11
The answer for x-coordinate is "11" of the line segment in a 3:4 ratio.
The middle value must be between 2.463 and 2.480. This means that the possible choics for the middle value are:
2.464
2.465
2.466
2.467
2.468
2.469
2.470
2.471
2.471
2.472
2.473
2.474
2.475
2.476
2.477
2.478
2.479
<span>The only value in this list that ends with a "1" is 2.471, so the missing digit must be a </span>7<span>.</span>
