Answer:
Option (1).
Step-by-step explanation:
In the figure attached,
Houses of three friends Jo, Boris and Carrie are located at the vertices of a triangle.
They want to meet at a place which equidistant from these vertices.
A point in a triangle which is equidistant from the vertices is its Circumcenter.
A circumcenter of a triangle is a point of intersection of perpendicular bisectors of its sides.
Therefore, the next step to find the meeting place should be,
Option (1). They should find the midpoint of the segments which connect their houses.
<h3>Answer: 8x+3y = 16</h3>
============================
Work Shown:
x = number of hours spent running
8x = distance he runs (since he runs at 8 mph)
y = number of hours spent walking
3y = distance he walks (he walks at a speed of 3 mph)
8x+3y = total distance = 16 miles
8x+3y = 16
This equation is in standard form Ax+By = C
--------
Extra Info
Solving for y will get
8x+3y = 16
3y = -8x+16
y = (-8x+16)/3
y = (-8x)/3+16/3
y = (-8/3)x+16/3
This is in slope intercept form y = mx+b
m = -8/3 is the slope
b = 16/3 is the y intercept
Answer:
D. is the correct one.........
The numbers are 16 and 4
Reason: 16+4=20 and (16*3)-(4*2)=48-8=40
