b) x= -0.4
c) x=2.5
d) x= -2.5​

Answer:

((X_2 - X_1)/4, (Y_2 - Y_1)/4)

Step-by-step explanation:

C = The new point

X_1 = The x coordinate of A

X_2 = The x coordinate of B

X_3 = The x coordinate of C

Y_1 = The y coordinate of A

Y_2 = The y coordinate of B

Y_3 = The y coordinate of C

The distance between A and the new point, C, is equal to 1/4 the distance from the X coordinate of A to the X coordinate of b.

So,  X_3 = (X_2 - X_1)/4

The Y is the same thing but for the Y coordinate.

Y_3 = (Y_2 - Y_1)/4

This means that the coordinates of C are equal to ((X_2 - X_1)/4, (Y_2 - Y_1)/4)

Final answer:

To find the coordinates of a point that's a quarter way from point a to point b, use the following formula: [(1*x2 + 3*x1) / 4, (1*y2 + 3*y1) / 4], where (x1, y1) and (x2, y2) are the coordinates of points a and b respectively.

Explanation:

In mathematics, to find the coordinates that are 1/4 of the way from point a to point b, you simply need to apply the formula for finding a point along a line segment connecting two points. If you have two points (x1, y1) - coordinates of point a and (x2, y2) - coordinates of point b, a point P that divides the line segment AB in the ratio of m:n (in this case m=1, n=3 since it's 1/4 of the way) has the coordinates: [(mx2 + nx1) / (m+n), (my2 + ny1) / (m+n)].

So, if point a = (x1, y1) and point b = (x2, y2), the coordinates of the point that is 1/4 of the way from a to b is given by: [(1*x2 + 3*x1) / 4, (1*y2 + 3*y1) / 4].

Answer:

$23.40

Step-by-step explanation:

Total money of William = Money from Lemonade + Money from Cookies

Money from lemonade:

It is given as $17.55

Money from cookies:

It is of money from lemonade. So we have;

So, $5.85 from cookies.

Hence, total money of William is $17.55 + $5.85 = $23.40
