A gift store sells keychains for $3 each and picture frames for $9 each. Part A.
Write a number pattern for the cost of 0,1,2,3,4, and 5 keychains. Then write a second number pattern for the cost of 0,1,2,3,4, and 5 picture frames.

Part B.
How do the corresponding terms of the two number patterns compare?​

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

- (2, -7)

- lines r and s and lines t and u must be parallel

middle maybe?
