Answers

Answer 1
3=4m+ b
-1=3m+b

m=4
plug in to either equation,
3=16+ b
b=-13

Thus, C would be the answer.
Answer 2

Answer:  The correct option is (C) [tex]y=4x-13.[/tex]

Step-by-step explanation:  We are given to write a rule for the linear function given in the graph.

Since the graph is a straight line, so we are to find the equation of the line to find the rule.

From the graph, we note that

the points (3, -1) and (4, 3) lie on the straight line.

So, the slope of the line will be

[tex]m=\dfrac{3-(-1)}{4-3}\\\\\\\Rightarrow m=4.[/tex]

Since the line passes through the point (4, 3), so the equation of the line is given by

[tex]y-3=m(x-4)\\\\\Rightarrow y-3=4(x-4)\\\\\Rightarrow y=4x-16+3\\\\\Rightarrow y=4x-13.[/tex]

Thus, the required rule for the linear function is

[tex]y=4x-13.[/tex]

Option (C) is correct.

A cart travels a distance of 3.6 meters in 1.8 seconds. The average speed of the cart is: Answer: meters per second.

Answers

To find the average speed, divide 3.6/1.8.

3.6/1.8 = 2

The average speed is 2 meters per second.

The average speed of the cart is 2 meters/second.

Given that, a cart travels a distance of 3.6 meters in 1.8 seconds.

We need to find the average speed of the cart in meters per second.

What is the average speed?

The general speed average formula for an object is given as [Average Speed = Total distance travelled ÷ Total time taken]. SI unit of average speed is m/s.

Now, the average speed=3.6/1.8

=2 meters per second

Therefore, the average speed of the cart is 2 meters/second.

Two pounds of dried cranberries cost $5.04, 3 pounds of dried cranberries cost $7.56, and 7 pounds of dried cranberries cost $17.64. Write an equation that gives the cost y of x pounds of dried cranberries? Please explain how you got your answer!

Answers

The answer is y=2.52x

The cost equation for dried cranberries is y = 2.52x.

Cost equation:

Using the given data:

2 pounds for $5.04 means each pound costs $5.04/2 = $2.52.

3 pounds for $7.56 means each pound costs $7.56/3 = $2.52.

7 pounds for $17.64 means each pound costs $17.64/7 = $2.52.

Therefore, the cost equation: y = 2.52x where y is the cost and x is the pounds of dried cranberries.

A customer at a raceway can drive around the track 54 times for $12. At this rate, how many times can the customer drive around the track for $8?

Answers

well first you need to find out how many times a customer can drive around the track for $1. divide 12 into 54 and you would get 4.5. that means 1 dollars worth and you can drive around the track 4.5 times. so to find out how many times a customer can drive around the track for $8 all you have to do is multiply 4.5 times 8 and you get 36 meaning the customer can drive around the track 36 times for $8.

The number is 48.  Round the 8 up to make it 50.

Given that digits 8 and 4 makes up a number, and when rounded, it gives us 50, the number would be: 48.

Recall:

When rounding a number, if the number close to the number you want to round is more than 4, you round up. For example, rounding 39 to nearest ten, 9 is more than 4. Therefore, we will round up 39 as 40.

Answers

Roger would have 4 times as much as Maria
Carol would have 2 times what Maria has

We then add everything up, how big a cut, they each have

4+2+1 = 7

Now we divide the 77 by 7

77/7 = 11

Now we just multiply by how much each of them has

Maria = 11*1 = 11
Carol = 11*2 = 22
Roger = 11*4 = 44
C+(C*2)+(C/2)=77
C=22

The sum of 3 consecutive odd numbers is 51 what is the second number in the sequence

Answers

Answer:

The second number in the sequence is 17.

Step-by-step explanation:

Let the three consecutive odd numbers be 2x-1,2x+1 and 2x+3

As per the question, the sum of the 2 odd numbers is 51.

So forming the relevant equation:

(2x-1) + (2x+1) + (2x+3) = 51

=> 6x + 3 = 51

=> 6x = 51-3 = 48

=> x = 48/6 = 8

Calculating the individual numbers:

2x-1 = 2*8 -1 = 16 - 1 = 152x+1 = 2*8+1 = 16 + 1  = 172x+3 = 2*8 +3 = 16 + 3 = 19

So the consecutive odd numbers are 15,17,19 and the second number in the sequence is 17.
