Answer:
BC is 10 unit
BD is 15 units
Step-by-step explanation:
Here, given the end points of the line segments, we want to calculate BD and DC
Mathematically, the distance between two points can be calculated using the formula;
D = √(x2-x1)^2 + (y2-y1)^2
For BD, we have the following
D = √(14-5)^2 + (14-2)^2
D = √(9)^2 + 12^2
D = √81 + 144
D = √(225)
Distance BD is 15 units
For BC, we have the following
D = √(11-5)^2 + (10-2)^2
D = √(6)^2 + 8^2
D = √100
D = 10
Answer:
X=4, y=-7
Step-by-step explanation:
To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2
2(y)=2(-x-3)
2y=-2x-6
——————
add above equation 2y=-2x-6
to second equation Y=2x-15
add together. 3y=-21
Y=-7
—————————————-
solve for x by substituting y value (7) into either equation
y=-x-3
-7=-x-3
-4=-x
4=x

Answer:
55.75
Step by step explain:
33.00 divided by 4 equals 8.25
then multiply 8.25 by 7 which equals 55.75
