If C is between A and B, then, we can write the equation

AB = AC + CB


Substitute the value of AB and the expressions for AC and CB in terms of x.


40 = (2x+10)+(3x-5)


We can now solve for x.



40-10+5= 2x+3x



35=5x


Dividing by 5.


7=x


AB=40



AC=2(7)+10



AC=14+10



AC=24




BC=3(7)-5



BC=21-5


BC=16

Answer:

\displaystyle M =  ( 3,1 )

Step-by-step explanation:

we are given the endpoint i.e P and Q of a line segment

we want to figure out the Midpoint of the Line segment

in order to do so we can use Midpoint formula given by

\displaystyle M =  \bigg( \frac{ x_{1} +  x_{2}  }{2}  , \frac{ y_{1} +  y_{2}}{2}  \bigg)

so let

x_1=-2\\x_2=8\\y_1=-2\\y_2=4

substitute

\displaystyle M =  \bigg( \frac{  - 2 +  8}{2}  , \frac{  - 2 +  4}{2}  \bigg)

simplify addition:

\displaystyle M =  \bigg( \frac{  6}{2}  , \frac{  2}{2}  \bigg)

simplify division:

\displaystyle M =  ( 3,1 )

hence,

the Midpoint of the line segment is (3,1)

The equation x^2−8x−5=0 can be transformed into the equation (x−p)^2=q, where p and q are real numbers. What is the value of q?
Setler79 [48]

Answer:

x = 5

  or

x = 3

Step-by-step explanation:

The first term is,  x2  its coefficient is  1 .

The middle term is,  -8x  its coefficient is  -8 .

The last term, "the constant", is  +15

Step-1 : Multiply the coefficient of the first term by the constant   1 • 15 = 15

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   -8 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8
