B is the midpoint of line Ac
AB=3x
AC=7x-5
How do I find what the value of BC is?
Since B is the midpoint, AB = BC
3x = 7x -5
4x = 5
x = 5/4
draw a pair of xy-axes on grath
draw a pair of ax-axes on graph paper,each scaled from -8 to 8.plot the points r(-5,2),c(-4,3),h(-1,4)and s(-3,1)and connect them to form a quadrilateral
To find the value of BC, we can substitute the value of x back into the equation AB = BC.
Since AB = 3x, we have AB = 3 * (5/4) = 15/4.
Therefore, BC = 15/4.
To find the value of BC, you need to first find the value of x.
Since B is the midpoint of AC, we know that AB is equal to BC.
So, we can set up an equation by equating the lengths of AB and BC:
AB = BC
Substituting the given values, we have:
3x = 7x - 5
Now, we can solve this equation for x.
Subtracting 3x from both sides, we get:
0 = 7x - 3x - 5
Combining like terms, we have:
0 = 4x - 5
Adding 5 to both sides, we get:
5 = 4x
Finally, dividing both sides by 4, we get:
x = 5/4
Now that we know the value of x, we can find the length of BC by substituting the value of x back into the equation:
BC = 3x
BC = 3 * (5/4)
BC = 15/4
Therefore, the value of BC is 15/4.
