Find the slope (m) of the line containing the points (1, 2) and (2, 5).
Vladimir [108]

Answer:

<h2>3</h2>

Step-by-step explanation:

<h3>Step 1: Identify two points on the line</h3>

1,2 & 2,5

<h3>Step 2: Select x1, y1 & x2, y2</h3>

x1 = 2, y1 = 5     x2 = 1, y2 = 2

<h3>Step 3: Use the Slope Formula</h3>

change y/ change x

<u><em>IMPORTANT: it is change in y over change in x, not the other way around. It will be wrong if done the other way, though that would seem to be more logical, since x is the first variable in the pair.</em></u>

Y   5 -2 = 3        

X   2 - 1 = 1

3/1 = 3

With three boys on a large scale, it read 170 pounds. When Adam stepped off, the scale read 100 pounds. When both Adam and Ben s
Elden [556K]

Answer:

Adam = 70 pounds

Ben = 40 pounds

C = 60 pounds

Step-by-step explanation:

We can work out some equations based on the given information:

We can call the boys A, B and C

so,

  • when all three boys are standing on the scale, it reads 170 pounds.

A + B + C = 170 - Eq(1)

  • when Adam stepped off, the scale reads 100. This means that the combined weight of the remaining two boys is 100.

B + C = 100 - Eq(2)

  • when both Adam and Ben stepped off, the weight of the remaining boy is shown on the scale.

C = 60

So we already knew the weight of boy C. (it was in the question all along)

C = 60 pounds

<u>Now to find the individual weights of the remaining boys, we can work our way backwards</u><u> </u>

we can put this value back in Eq(2), to find the weight of boy B.

B + C = 100

B + 60 = 100

B = 100 - 60

B = 40

the

the weight of boy B (Ben) is B = 40 pounds

now we can put all of the known weights of the boys in Eq(1) to find the weight of Boy A.

A + B + C = 170

A + 40 + 60 = 170

A + 100 = 170

A = 170 - 100

A = 70

the weight of boy A (Adam) is A = 70 pounds

The Answer:

Adam = 70 pounds

Ben = 40 pounds

C = 60 pounds
