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).

Step-by-step explanation:
dy/dx
= d/dx [x / (1 - x²)]
= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²
= (1 + x²) / (1 - x²)².
When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.
=> 1 + x² = 1 - x²
=> 2x² = 0, x = 0.
Also when x = 0, y = (0) / [1 - (0)²] = 0.
Hence the coodinates is (0, 0).
Answer:
y = 9
Step-by-step explanation:
m<1 + 2x = 180° because these angles are supplementary
61° + 2x° = 180°
2x = 180 - 61
2x = 119 divide both sides by 2
x = 59.5
Since f is parallel to s:
2x + (7y-2) = 180°
2×59.5 + 7y - 2 = 180
119 + 7y - 2 = 180
7y = 180 - 117
7y = 63 divide both sides by 7
y = 9

Answer:
13 miles
Step-by-step explanation:
Write and solve an equation involving this information, using x as the distance traveled, in miles:
Cost(x) = $6.75 = $3.50 + ($0.25/mile)x
First, subtract $3.50 from both sides, obtaining: $3.25 = ($.25/mile)x.
Next, divide both sides by $0.25/mile:
$3.25
x = ------------------ = 13 miles
$0.25/mile
The length of the taxi ride was 13 miles.
