Answer:

see below

Step-by-step explanation:

You want an arithmetic expression using four 4s that evaluates to each of the digits 0-9.

<h3>Expressions</h3>

0 = 4 +4 -4 -4

1 = 4/4 +4 -4

2 = 4 -(4 +4)/4

3 = (4 +4 +4)/4

4 = 4 + (4 -4)*4

5 = (4*4 +4)/4

6 = 4 +(4 +4)/4

7 = 4 +4 -4/4

8 = 4 +4 +4 -4

9 = 4 +4 +4/4

The linear equation that represent the left balance of sanjaya’s y after visiting x number of days is:

y = 10x + 500.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

From the data given, we have that:

The y-intercept is of 500.

The slope is of 10.

Hence the balance is given as follows:

y = 10x + 500.

Need this asap i need to find out which is a function but i get really confused on these things

Answer:

Step-by-step explanation:

Use the "vertical line test." Draw a vertical line through each graph. If the line intersects the graph in more than one place, the graph does NOT represent a function. Only the graph in the upper, right-hand corner represents a function, as a vertical line intersects this graph in only one place.

Nick, Joey, Beki, and Carmen ran in the town's annual road race. Each person had a different jersey number {2, 13, 20, and 34} a

erastova [34]

Answer:

Beki's jersey number is 34. She last 12 minutes

Nick's jersey number is 20. He last 10 minutes

Carmen's jersey number is 2. She last 14 minutes

Joey's jersey number is 13. He last 11 minutes

Step-by-step explanation:

• The sum of the digits on Beki's jersey number is 7. Therefore, Beki's number is necessarily 34 (3+4 = 7)

• Nick's jersey number is 18 greater than Carmen's. Therefore, Nick's jersey number is 20 and Carmen's jersey number is 2 (2 + 18 = 20). If Carmen's jersey number was 13, 13+18 = 31 which is not included in the options. If it was 20, 20+18 = 38 is not included either.

• From previous items, Joey's jersey number is 13

• The runner with the lowest jersey number also ran the slowest time. Therefore, Carmen last 14 minutes

• Nick finished exactly 2 minutes faster than Beki. Therefore, Nick's time is 10 minutes and Beki's time is 12 minutes, because from the remaining options (10, 11 and 12) this is the only combination 2 minutes apart.

• From previous items, Joey's time is 11 minutes
