Answer:

change in y /change in y to get the gradient . therefore (6--6)=12  and (2--4)=6 thus 12/6=2 that the gradient.

Step-by-step explanation:

form the equation ion form of y=mx+c

and thus the equation y= 2x+c

if you take one point coordinate  such as (2,6)

such that y=6 and x=2 thus the equation will be

6=2*2+C

6=4+C

C=6-4=2

Is he correct, or not?

Answers

Answer:

C. His estimate is incorrect; it should be closer to 12 than 11.

Step-by-step explanation:

1. 11^2 is 121, √(140^2) is 140, and 12^2 is 144.

2. Based off these numbers 140 is closer to 144, meaning that √(140) is closer to 12 than 11.

Therefore, the correct answer is C. His estimate is incorrect; it should be closer to 12 than 11.

Answer:

1A. Half jump

1B. 2/3 is half of 4/3

2. 4

Step-by-step explanation:

1A. The remainder of 2/3 is shown in the model by a half jump. It is a half jump because a full jump is 4/3.

1B. We know that the remainder represents 1/2 of the jogging loop because 2/3 is half of 4/3.

2. Convert 2 1/2 into a mixed number with the denominator as eighths. We then get 20/8 divided by 5/8. After that, we can see that 5/8 goes into 20/8 4 times. (5/8 + 5/8 + 5/8 + 5/8 = 20/8)
