Answer:

The midpoint of the segment is (6,5)

Step-by-step explanation:

To find the midpoint of a segment we use the formula

midpoint = (x1+x2)/2, (y1+y2)/2

= (10+2)/2 , (7+3)/2

= 12/2, 10/2

=6,5

The midpoint of the segment is (6,5)

Find the point on the plane 4x+3y+z=10 that is nearest to (2,0,1). What are the values of x, y, and z for the point? x= 28 /

Answer:

$\frac{1}{\sqrt{26}}$ .

Step-by-step explanation:

The minimun distance between a point and a plane is the perpendicular distance. The formula is

d = $\frac{|Ax_0+By_0+Cz_0+D|}{\sqrt{A^{2}+B^{2}+C^{2}}}$

where $(x_0,y_0,z_0)=(2,0,1)$ , A=4, B=3, C=1 and D=-10. So, the distance is

d = $\frac{|8+1-10|}{\sqrt{16+9+1}}$

d = $\frac{|-1|}{\sqrt{26}}$

d = $\frac{1}{\sqrt{26}}$ .

Answer:

$\sf \dfrac{BC}{BD} = \dfrac{2}{4}$

Explanation:

BD distance is 4 units

BC distance is 2 units

so in fractions:

$\sf \dfrac{BC}{BD} = \dfrac{2}{4}$

$\sf \dfrac{BC}{BD} = \dfrac{1}{2}$

Solution to 7(y-3) =2(y-9) +2y

dolphi86 [110]

<h3>The value of y is equal to 1.</h3>

7(y - 3) = 2(y - 9) + 2y

Distributive property.

7y - 21 = 2y - 18 + 2y

Combine like terms.

7y - 21 = 4y - 18

Subtract 4y from both sides.

3y - 21 = -18

Add 21 to both sides.

3y = 3

Divide both sides by 3.

y = 1
