4x+3(2x-1) -4x 3(2x-1)= 6x-3 -4x 4x+6x-4x= 6x-3
Answer:
<h3>The option B) is correct</h3><h3>Therefore the coordinate of B

is (6,-3)</h3>
Step-by-step explanation:
Given that the midpoint of segment AB is (4, 2). The coordinates of point A is (2, 7).
<h3>To Find the coordinates of point B:</h3>
- Let the coordinate of A be
is (2,7) respectively - Let the coordinate of B be

- And Let M(x,y) be the mid point of line segment AB is (4,2) respectively
- The mid-point formula is
<h3>

</h3>
- Now substitute the coordinates int he above formula we get

- Now equating we get

Multiply by 2 we get Multiply by 2 we get


Subtracting 2 on both
the sides Subtracting 7 on both the sides


Rewritting the above equation Rewritting the equation

<h3>Therefore the coordinate of B

is (6,-3)</h3><h3>Therefore the option B) is correct.</h3>
Answer:
y = -1/8 x² + 5
Step-by-step explanation:
Parabola opens vertically and vertex (h,k) = (0,5), pass point (4,3)
basic formula: y = a(x - h)² + k
y = a (x-0)² + 5
y = ax² + 5 pass (4,3)
3 = 16a + 5
a = (3-5)/16 = -1/8
equation: y = -1/8 x² + 5
check: pass another point (-4,3)
-1/8 * (-4)² + 5 = -2 + 5 = 3
Answer:
(0,2)/(4,5)
Step-by-step explanation:
Im Pretty Sure That's Correct.
