You can read it of the graph which is (1,3) or also calculate it with vectors:

calculate the vector CD:
(5-(-3),2-4)=(8,-2)
to calculate the midpoint you need half of the vector length:
(8,-2)/2=(4,-1)
add the vector to C:
(-3,4)+(4,-1)=(1,3)=midpoint of CD

so it's the third option

3. If each person paid an equal amount, who would save the most money? Explain your reasoning using at least two complete senten

Rzqust [24]

There ar 4persons so each will pay

$\\ \sf\longmapsto \dfrac{83.90}{4}=20.975$

Only two persons have spent more money than everyone average i.e mia and Jasmin.

Now

Mia has-28.47
Jasmin has=20.99

Mia left more money so she saved most money.

What is the best description for the lines

jeyben [28]

Answer:

Lines are described as connecting curve joining two points.

Step-by-step explanation:

In coordinate geometry, graph theory, we have points which do not occupy any space.

Any two points can be connected by a curve or a straight line. If two points are joined by a straight line, then we have the slope of the line i.e. the tangent of angle of the line with x axis is constant.

Straight lines would be of the form ax+by+c=0

Hence in equation form, lines would have equations in linear form of both x and y.

Lines have constant slope throughout the region.

Lines can be extended from -infinity to +infinity

Any two distinct points can make a line, but 3 points need not lie on the same line.

Find KL<br><br> step by step

stich3 [128]

Answer:

7x-2 = 12x-22

-7x

-2=5x-22

+22

20=5x

÷5

x=4

KL is 7x-2, so substitute the value of x.

7 x 4 - 2 = 26

KL = 26

Hope this helps!

Solve the problem.

MA_775_DIABLO [31]

Circumference = 2πr

r = 9

Circumference = 2π(9)
Circumference = 18π
Circumference = 18(3.14)
Circumference = 56.52

Distance: 56.52 meters
