(19-16), (-7, -15)

(-15-(-16)/(-7-19)

(1)/(-26)

1/-26 is the slope.

What you do is you basically subtract the x's and y's i forget exactly how my teacher explained it but this would be how you would do it you would always have the pairs on one side like how the -16 and 19 is on one side, that's what you want.

A rectangular vegetable patch has an area of 56 square meters and a

vredina [299]

Answer:

The dimensions of the vegetable patch is 8 m by 7 m.

Step-by-step explanation:

Area of a vegetable patch is 56 square meters and the perimeter is 30 m.

If l is length and b is breadth, then area and perimeter of a rectangle is given by :

$A=l\times b$

$P=2(l+b)$

Substituting the values in the above formulas as :

$l\times b=56\ ....(1)$

and

$2(l+b)=30\\\\l+b=15\ .....(2)$

We need to solve equation (1) and (2) to find the values of l and b such that :

Equation (2), l = 15 - b

Equation (1) becomes,

$(15-b)b=56\\\\b=7\ m, 8\ m$

If b = 7 m, so, l = 8 m

If b = 8 m, l = 7 m

So, the dimensions of the vegetable patch is 8 m by 7 m.

Nick and Sally run on the 100m straight track,Nicks's speed is 3m/s,Sally's soeed is 2m/s.If they both start from two sides of t

Pepsi [2]

They would meet 30 times after 10 minutes.

Since Nick and Sally run on the 100m straight track, and Nicks's speed is 3m / s, while Sally's speed is 2m / s, if they both start from two sides of the track, running towards each other continuously, to determine how many times they would meet each other after 10 minutes the following calculation should be performed:

30 x 20 + 2 x 20 = 60 + 40 = 100
10 minutes = 600 seconds
600/20 = X
30 = X

Therefore, they would meet 30 times after 10 minutes.
