Answer:
0.92
Step-by-step explanation:
We turn 23/25 into 92/100. And since 100 is the denominator the decimal is 0.92
B is your answer there all the same
The coordinates of point r(-8,0).
<h3>What is midpoint formula in coordinate geometry?</h3>
The coordinates of the point r(x,y) which divides the line segment joining the points p(
,
) and q(
,
) internally in the ratio :
are

Given that,
Two end points on the line q(-14,0) and s(2,0). point r(x,y) is the partition of the line segment from q to s in a ratio 3:5
= 3 and
= 5
By using the midpoint formula




Hence, The coordinates of point r(-8,0).
