Answer:
175.5in
Step-by-step explanation:
12 x 9 + 67.5
If this answer is incorrect (Which it should not be) than try 243
Answer:
The other endpoint is (11,-9)
Step-by-step explanation:
<u>Midpoint Formula</u>
<u />
We already know the another endpoint which is (3,5). We substitute x = 3 and y = 5 in the formula. You can substitute in x1, x2 or y1, y2. I'll substitute in first x-term and first y-term instead.
Because sum of two x-coordinate (along with y-coordinate) divided by two must equal to the midpoint (Let's say that you get the value of midpoint when using midpoint formula.)
Solve the equation for both terms.
Cancel the denominator by multiplying the whole equation by 2.
Isolate x-term and y-term.
Therefore, when x = 11, y = -9. We can write in ordered pair as (11,-9). The ordered pair (11,-9) is our other endpoint of the line segment. This can be proved by using the distance formula between midpoint and endpoints.
<em>Note: The distance of (3,5) and (7,-2) must equal to the distance of (11,-9) and (7,-2)</em>

notice the equations in slope-intercept form, the first one has a slope of -1, the second one has a slope of 1.
if the slopes are equal, and the constant is different, they lines are parallel.
if the slopes are equal, and the constant is the same the equations are exactly the same thing, and the lines are coincident, on slapped on top of the other.
if the slopes differ, like here, then they have a solution, where they
intersect.
Answer:
It's A.
Step-by-step explanation:
this is a right angled triangle with the 2 legs = (a - 0) and (b - 0) - a and b.
So, by Pythagoras Theorem the hypotenuse = √(a^2 + b^2).
