Each pendant costs $1.90. The total costs to make the 2 necklaces (beads and pendant) is $10.20. You have to find how much the beads cost for BOTH necklaces so you would solve $3.20 x 2. You would get $6.40. So now you subtract $6.40 from $10.20 to find how much the pendant for both necklaces cost. That would be $3.80 now you just divide by 2 to find the cost of 1 pendant.

Simplify 6x+1 ty try to answer this and explain
Sergeu [11.5K]

Simplify the Value of:

6x     +       1   The equation is already simplified, There are no like terms.

You cannot factor    6x     +   1       either




Domain of:

6x     +    1

Solution:      [  - ∞    <    x    <   ∞ ]

Interval Notation:   [ (- ∞,  ∞) ]


Range of:

6x      +    1

Solution:    [    - ∞    <    f(x)   <    ∞ ]

Interval Notation:   [   (- ∞, ∞) ]


Parity of:

6x     +    1   =====>    Neither  even  nor odd


Axis interception points of:

6x   +   1

x-   Intercepts  ( - 1 / 6,   0 )

y-  Intercepts    ( 0,   1 )


Inverse of:

6x    +   1  =====>    x   -    1 / 6

Slope of:

6x    +   1

Answer:    ======>    m      =         6




Hope that helps!!!!!!!!!!                                        : )

values are 4 times as big as in the right figure

14) and 15) two thirds of the value in the left figure. the rotation is just to disorient you a lil :D just keep the 90° angle as a reference point
