John paid $50 for renting a cycle for 5 hours. Which graph shows the relationship between the cost of renting a cycle for differ

SpyIntel [72]

Answer:

Graph A <==

Step-by-step explanation:

$ 50 for 5 hours......50/5 = 10...thats $ 10 per hr

so the equation would be : y = 10x...with x being the number of hrs and y being the total cost.

So ur x axis will be the hours and your y axis will be the total cost.

so ur answer is :the title of the graph is cycle renting. the x axis (the horizontal axis)...since it is the hours, will be labeled 0,1,2,3,4,5,6

the y axis (the vertical axis)...since it is the total cost, will be labeled

0,10,20,30,40,50,60. points are plotted on (1,10),(2,20), and (3,30)

I need it by tmr ill give brainliest thx

Zina [86]

Answer:

21. B. Graph Z

23. A. neither function nor relation

24. D. relation only

Step-by-step explanation:

21. Graph Z is the only graph which does not pass the vertical line test

23. The graph does not pass the vertical line test, AND it is not merely given x and y points like a relation. It is graphed as a squiggly line with no given x and y points, therefore you could not make a relation from it either.

24. There is an x value of -4 twice, meaning the set does not pass the vertical line test, HOWEVER, it is a given collection of x and y values, making it a relation.

I would appreciate brainliest, have an amazing day

Solve for −4.2y+2.1>−2.52

Alchen [17]

Answer:

y < 1.1

Step-by-step explanation:

Step 1: Subtract 2.1 from both sides

-4.2y + 2.1 - 2.1 > -2.52 - 2.1

-4.2y > -4.62

Step 2: Divide both sides by -4.2

-4.2y / -4.2 > -4.62 / -4.2

Since you divided by a negative, that flips the sign.

y < 1.1

Answer: y < 1.1
