How are slopes and y intercepts to the number of solutions of a system of the liner

1 answer:

7 0

We assume a linear system with 2 variables.

If the slopes are the same, and y-intercepts are different, there are 0 solutions.

If the slopes are different, there is 1 solution.

If the slopes are the same, and the y-intercepts are the same, there are ∞ solutions.

The football fields at three different schools were measured, and it was found that their perimeters were 320 m, 360 m, and 400

Tomtit [17]

Let us say that,

<span>A = perimeter of football field of the 1st school</span>

B = perimeter of football field of the 2nd school

C = perimeter of football field of the 3rd school

So that:

A = 320 m

B = 360 m

C = 400 m

So the first thing we have to do to find for the minimum laps to make is to divide every perimeter by the smallest one, therefore divide all by 320 m, hence:

A’ = 1

B’ = 1.125

C’ = 1.25

Now multiply everything by a number such that all laps will be a whole number, in this case multiply everything by 8:

A’ = 8

B’ = 9

C’ = 10

Hence the laps to run are:

On friday ,a museum had 185 visitors.on saturday,there were twice as many visitors as Friday.On Sunday, 50 fewer people visited

Taya2010 [7]

This is the equation
185+185(2)+185-50
185+370+185-50 (you multiply 185 times 2 first)
370+370-50 (you add 185 to 185)
740-50 (you add 370 to 370)
740-50=690
There were 690 visitors during these three days.
