The local hardware store wants to increase their inventory. last year 15 electric screwdrivers cost them $300. at the same cost, how much would 45 screwdrivers cost them this year?

Cost of 45 screwdrivers will be = $900

Step-by-step explanation:

Last year 15 electric screwdrivers cost to the local hardware store = $300

So per screwdriver cost =

=

= $20

Now we have to calculate the cost of 45 screw drivers.

Since cost of 1 screwdriver = $20

So cost of 45 screwdrivers = 20×45 = $900

b if for most of the graph

d if y intercept

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
