SVETLANKA909090 [29]

Answer:

The function that represents the total cups of coffee they made today is h(x)=9x-7.

Step-by-step explanation:

The given function are

f(x)=6x-8

g(x)=3x+1

Where, Kate's total cups of coffee made is represented by f(x) and Stella's total cups of coffee made is represented by g(x).

The total cups of coffee they made today is represented by the function

h(x)=f(x)+g(x)

Substitute the value of functions.

h(x)=6x-8+3x+1

Combine like terms.

h(x)=(6x+3x)+(-8+1)

h(x)=9x-7

Therefore the function that represents the total cups of coffee they made today is h(x)=9x-7.

"Find the midpoint of AB .
Diano4ka-milaya [45]

Answer:

The midpoint of AB = (x,y)=(1,1)

Step-by-step explanation:

Given : A line AB

To find : Midpoint of AB.

Solution :

Consider the figure


Then , Points of A =    (x_{1} ,y_{1} )   = (-2,0)


Points of B =    (x_{2} ,y_{2} )   = (4,2)


Now to find mid point we will use midpoint formula :


(x,y) =(\frac{x_{1} +x_{2} }{2},\frac{y_{1} +y_{2} }{2} )


(x,y) =(\frac{-2 +4 }{2},\frac{0 +2 }{2} )


(x,y) =(\frac{2 }{2},\frac{2 }{2} )


(x,y) =(1,1 )


Thus, The midpoint of AB = (x,y)=(1,1)
