Step-by-step explanation:
Imagine this segment, given that m is the midpoint of segment JK...
J________M________K
JM = 7x-32 MK = 89 - 4x (given)
If m is the midpoint, then JM and MK are the same lengths (equal to each other). We can use that to first find what <em>x</em> is.
Steps to find x (we have to get x by itself):
(we haven't found the answer yet! we only found x)
Now that we found x, we can find segment MK. Now we know that:
Let's plug x into the equation:
Answer: 
<span>y = -3.5x - 3.5
y = -3.5x 3.5
I do not see a sign for the constant term (y-intercept) in the second equation.
In any case, since the equation reads y=-3.5x + (y-intercept) in both cases, the lines are parallel to each other.
If the y-intercepts are identical, then the equations are also identical, therefore there are infinitely many solutions.
If the y-intercepts are different (e.g. +3.5 and -3.5), then the two equations form distinct (i.e. not coincident) parallel lines, and therefore has solution.
So it depends on the missing sign, and you will be able to judge when the sign is given.</span>
Answer:
The true options are:
2) Has exactly one pair of parallel sides
4) Has exactly one pair of congruent sides
5) Both pairs of opposite sides are congruent
7) There are right angles at all 4 vertices
9) The diagonals are congruent
10) The diagonals bisect each other.
Answer:
Step-by-step explanation:
Diameter:
A line passing through the center of the circle touching the circle at two points, is called diameter.
OR
The chord passing through the center is diameter.
It is double of the radius.
so,
Diameter = (2) (Radius of the circle)
Radius:
Diameter divided by 2.
OR half of the diameter is called radius.
So,
Radius = (1/2) (diameter of the circle)
Area of a circle:
Area of a circle =πr^2
Using π=3.14
Area ≈ (3.14) (radius squared)
Circumference of a cricle:
It is equal to 2πr
If π=3.14, then 2π=6.28
Circumference ≈ (6.28) (radius of the circle)
