Let the "population of linton" be represented by the letter L
and the "popluation of ellmore" be represented by the letter E
L = 12E
L + E = 9646
are the two equations we can get from the given information
plugging in L = 12E into the second equation we can get:
12E + E = 9646 [now solve for E]
13E = 9646 [added like terms]
E = 742 [divided 13 from both sides]
then plug this back into the first equation and get:
L = 12*(742) = 8904
Therefore the Population of Linton is 8904 people.
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality

Answer:
Step-by-step explanation:
Slope of a line passing through two points and is given by the formula,
Slope =
Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,
Slope '' = = 0
Therefore, slope of the line PQ parallel to the x-axis = 0
Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,
Slope '' = = ∞
Therefore, slope of the line MN parallel to y-axis is undefined.
Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.
These lines are perpendicular to each other.
Answer:
<u>The equator has the length:</u>
- C = 2πr, where π = 22/7, r = 6400 km
- C = 2*22/7*6400 = 40228.57 km (rounded)
a) Consider X and Y as two points on the circle with C = 40228.57 km.
<u>The distance between X and Y is:</u>
- d = C*(123 - 67)/360
- d = 40228.57*56/360 = 6257.78 km (rounded)
b) Since both X and Y are on the equator, they are at the same distance from the north pole, N.
<u>NX makes 90 degrees:</u>
- NX = C*90/360
- NX = 40228.57*1/4 = 10057.14 km (rounded)
