Answer:

There is no solution for given system of inequalities.

Step-by-step explanation:

The system of linear inequalities are given by  

y > \frac{3}{2} x - 1 ...... (1) and

y < \frac{3}{2} x - 1 .......... (2)

The solution of the inequality y > \frac{3}{2} x - 1 is shown in the graph by the blue shaded zone and the solution of the inequality  y < \frac{3}{2} x - 1 is shown in the graph by the red zone.

And it is clear that the solution of the system of inequality equation does not include the line y = \frac{3}{2} x - 1

Again, there is no overlap of the blue zone and the red zone so as to indicate solutions for both the inequalities.

Therefore, there is no solution for inequalities (1) and (2). (Answer)

Step-by-step explanation:

If half of the tuna sandwiches were on white bread then 21 of them would be white, meaning the other half would be on brown bread.

Then if 25% of ham sandwiches were on brown bread then 25% of 32 would be 8, so the final 75% would be on white bread, which would be 24.

Finally, with 20 more white bread sandwiches sold than brown bread it couldn’t be 80 and 20, it would be 40 brown bread in total and 60 white bread in total adding up to 100, as it says white sells 20 more than brown not only 20.

To finish this question you would add up the tuna and ham for white (21+24=45) then minus that from 60 (60-45=15) so there were 15 cheese sandwiches on white bread. And then for brown (21+8=29) then minus that from 40 (40-29=11) so therefore there are 11 cheese sandwiches on brown bread.

Answer:

Brown:

Tuna-21

Cheese-11

Ham-8

Total-40

White:

Tuna-21

Cheese-15

Ham-24

Total-60

Hope that helps!

2.) What value for c will make the expression a perfect square trinomial?
andre [41]

Answer : \frac{49}{4}

Given expression is x^2 - 7x + c

To make perfect square trinominal we use completing the square method

In completing the square method we add and subtract the half of square of coefficient of middle term

Here coefficient of middle term is -7

Half of -7 is \frac{-7}{2}

Square of \frac{-7}{2} is (\frac{-7}{2})^2 = \frac{49}{4}

So the expression becomes x^2 - 7x +  [tex] \frac{49}{4} that gives perfect square trinomial

Hence , the value of 'c' is \frac{49}{4}
