So carmen has b baseball cards and she gives 12 away.= b-12

So let the cards left be x

A line segment has endpoints at (2,10) and (10,2). What are the coordinates of the midpoint of the line segment?

IrinaVladis [17]

Answer:

(6,6)

Step-by-step explanation:

The midpoint formula is $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$ . Substitute (2,10) and (10,2) into this formula and simplify.

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} ) \\(\frac{2+10}{2},\frac{10+2}{2} ) \\(\frac{12}{2},\frac{12}{2} ) \\(6,6)$

What is the answer for this problem if f(x)= 3x+10x and g(x)=5x-3, find (f+g)(x).

hammer [34]

$(f+g)(x) =f(x)+g(x)=3x+10x+5x-3=\boxed{18x-3}\ D.$

L would measure at 54°. Because the angels of a triangle measure up to 180, you can set the equation up like this: 5x + 3x + 2x = 180. These are like values, so you can add them together to simplify a bit, yielding 10x = 180. Divide 180 by 10 to get x by itself, giving you 18. L = 3x, so 3(18) = 54.

Find the coordinates of the midpoint (-3,13) (10,-4)

xenn [34]

Answer:

The answer is

<h2> $( \frac{7}{2} \: , \: \frac{9}{2} )$ </h2>

Step-by-step explanation:

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

<h3> $M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )$ </h3>

where

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

From the question the points are

(-3,13) and (10,-4)

The midpoint M is

<h3> $M = ( \frac{ - 3 + 10}{2} , \: \frac{13 - 4}{2} ) \\$ </h3>

We have the final answer as

<h3> $( \frac{7}{2} \: , \: \frac{9}{2} )$ </h3>

Hope this helps you
