The endpoints of a line segment are at the coordinates (–6, 3, 4) and (4, –1, 2). What is the midpoint of the segment?
natulia [17]

Answer:

( - 1,1,3 )

Step-by-step explanation:

Use the midpoint formula:

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}, \frac{z_1+z_2}{2} )

We want to find the midpoint of the line

that has endpoints.

(\frac{ - 6+4}{2},\frac{3+ - 1}{2}, \frac{4+2}{2} )

We simplify to get;

(\frac{ - 2}{2},\frac{2}{2}, \frac{6}{2} )

This finally gives:

( - 1,1,3 )

The correct answer is A.

Select ALL the true statements.
ss7ja [257]

Answer:

A.

C.

Step-by-step explanation:

A. When adding a negative number to a positive, you subtract. 2.3 - 2.3 will equal 0.

B. When adding two negative numbers, you get an even smaller negative number. (-3.7) + (-4.1) = -7.8

C. When subtracting a negative number, the two negative signs become a positive. -12/4 is equal to 3. -2.6 + 3 is 0.4, which is positive.

D. 5/2 is the same as 2.5. If you subtract 2.5 from 2.5, you will get 0, which is not negative.

E. Two negative signs make a positive, so 72 + 100 is positive, not negative.

8x²+3y²=24

8x²+3y²-24=0

Let x be 1 ,

Therefore

8+3y²-24=0

3y²-16=0

3y²=16

y²=16/3

y=4/1.7

y=40/17
