What is the distance between points (9, –7) and (9, 4) on a coordinate plane?

1 answer:

4 0

Well lets use the distance formula kids which is d = square root of (x2-x1)^2+(y2-y1)^2 this should come out to 11 and dont worry geometry isnt that easy it comes with time like everything else its 11 the answer is 11

Match each expression to its equivalent expression.

Galina-37 [17]

Answer:

white 1: black 3

white 2: black 1

white 3: black 2

Step-by-step explanation:

white 1: the denominator for the x values so it becomes 1-2=-1 which becomes -1/3x +1/4

White 2: same case as the first so we add 1+2=3 3/3=1 so that makes it x+1/4

white 3: there is only one x values that has 4 as the denominator therefore that makes the answer 3/4x+1/3

What is the midpoint of QR. Q(2,4) and R(-3,9)

Eduardwww [97]

Answer:

The answer is

$( - \frac{1}{2} \: , \: \frac{13}{2}) \\$

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )\\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

Q(2,4) and R(-3,9)

The midpoint is

$M = ( \frac{2 - 3}{2} \: , \: \frac{9 + 4}{2} ) \\$

We have the final answer as

$( - \frac{1}{2} \: , \: \frac{13}{2}) \\$

Hope this helps you
