<u>Answer-</u>
<em>The length of BC is </em><em>8 units.</em>
<u>Solution-</u>
Mid-Point Theorem-
The line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side.
As given,
AD = DB, so D is the mid point of AB
FA = FC, so F is the mid point of AC
Hence, DF is the line segment connecting the midpoints of two sides of a triangle.
Applying the theorem,
BC = 2DF = 2×4 = 8 units
Answer:
m=1/2 b =6
Step-by-step explanation:
m is the the gradient ( as in how much that line slant), so just use the formula
y2 - y1
------------
X2 - x1
For b, that the y-intercept,
Once u found m
Just choose any one of the coordinate they gave u (4,8) or(-6,3)
It will give u the same answers
Let's say u chose (4,8)
Theredore x = 4, y =8
y=mx + b
8= 1/2 x 4 + b
b= 6
The other one would give u the same answer
<span>3x + 2y = 13
2x + 3y = 12</span>
Answer:
Maybe f(a) = 0.5b?
But it's not in terms of a.
Step-by-step explanation:
Simplify the equation:
-4a = -2b
a = 0.5b
Idk what next...
