Use the diagram shown. If BC = 14, AB = 11, and the perimeter of triangle ABC is 39, then what is the value of BD?
Answer:
BD=5.5
Step-by-step explanation:
11 divided by 2 gives you the answer
The measure of BD in the triangle ABC is 5.5 units.
Given that, BC = 14, AB = 11, and the perimeter of triangle ABC is 39.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
Now, the perimeter of triangle ABC = AB+BC+AC
⇒ 11+14+AC=39
⇒ 25+AC=39
⇒ AC=39-25
⇒ AC=14 units
Since, BC=AC=14 units, so ΔABC is isosceles triangle
Thus, DC is perpendicular bisector to AB, then AB/2 = BD
= 11/2 = 5.5 units
Therefore, the measure of BD in the triangle ABC is 5.5 units.

Multiplying both sides by 100 and dividing both sides by 50,
we have x = 60 ×

Answer:
y=2/2 x -800
Step-by-step explanation:
if you look the line intercepts Y at -800 and slope form is y=mx+b and B is your Y-intercept so you can easily find that. Now the next time the line touches a point on the graph is 2 points up and 2 points to the right, so your slope is 2/2. Remember your slope is always rise over run.

Answer:
Point A(5, -1) is mapped to A'(1, 5)
The rule is:
(x, y) → (-y, x)This is 90° anticlockwise rotation
Point B(-4, 6) will map to:
B(-4, 6) → B'(-6, -4)Enter the value of n so that the expression (5y - 2.3) + (-2y -4.3)
is equivalent to (3y-n).
Answer:
Step-by-step explanation:
(5y - 2.3) + (-2y - 4.3) = 3y - n Remove the brackets
5y - 2.3 - 2y - 4.3 = 3y - n Combine like terms
3y - 6.6 = 3y - n Subtract 3y from both sidess
- 6.6 = - n Divide by - 1
6.6 = n

Answer:
IS a parallelogram
Step-by-step explanation:
The slope formula for the slope of the line between points (x1, y1) and (x2, y2) is ...
m = (y2 -y1)/(x2 -x1)
The distance formula for the length of that same line is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, you're asked to use each of these formulas 4 times, once for each side of the quadrilateral. I find it convenient to let a calculator or spreadsheet do the repetitive calculations. The result is attached.
The attachment shows that opposites sides have the same length and slope, so are parallel. The quadrilateral is a parallelogram. (The two points used in each calculation are the ones on the result line and the line immediately below. That is why point B is copied to the end of the list.)
_____
Additional comments
There are much simpler ways to prove the figure is a parallelogram. My favorite is to add the coordinates of the end points of the diagonals:
B +D = (-2+6, -9-3) = (4, -12)
C +E = (0+4, -5-7) = (4, -12)
These values being the same demonstrates the midpoints of the diagonals are coincident. That will only be the case if the quadrilateral is a parallelogram.
__
If you must use slope and distance formulas, showing either pair of opposite sides is parallel and have the same length is sufficient to guarantee that the other two sides are also parallel and have the same length. That is, the calculations required in this problem only need to be applied to one pair of opposite sides. (Using a spreadsheet, it's not a lot of extra work to do the calculations for both pairs of opposite sides.)
Solve the following system of equations using the substitution method.
The problem- y= -2x+11
3x + y = 18
Answer:
x = 7
y = -3
Step-by-step explanation:
the first equation is already solved for 'y' so we can substitute '-2x+11' for 'y' in second equation
3x + (-2x + 11) = 18
x + 11 = 18
x = 7
solve for 'y'
y = -2(7) + 11
y = -14 + 11
y = -3
