Answer:
.
Step-by-step explanation:
It is given that Point A is at (-5, -4) and point B at (-3, 3).
We need to find the coordinates of the point which is 3/4 of the way from A to B.
Let the required point be P.


It means, point P divides segment AB in 3:1.
Section formula: If a point divides a line segment in m:n, then

Using section formula, we get




Therefore, the required point is
.

Answer:
Step-by-step explanation:
1. Make 1 2/7 an improper fraction = 9/7
2. Multiply 7 on both numerator and denominator for 2/3 to make 14/21, and multiply 3 for both numerator and denominator for 9/7 to make 27/21.
3. Add them together. 14/21+27/21=41/21.
4. (Optional) If the question is asking for mixed numbers, 41/21 = 1 20/21.
F: R -> R, f(x) = ax + b;
f(1) = 8 => a + b = 8;
f(2) = 14 => 2a + b = 14 => a = 6 and b =2;
f(3) = 20 => 6*3 + 2 = 20 True;
f(4) = 26 => 4*6 + 2 = 26 True;
then, f:R -> R, f(x) = 6x + 2;
