Sabendo que x2 + y2=74 e que xy=35, calcule valor de (x - y2)2

Ann [662]

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

- x²+y²<span>=74
xy=35

2. Therefore, you have that (x-y)</span>² is:

=(x-y)²
=x²-2xy+y²
=(x²+y²)-2xy

3. When you substitute the values given in the problem, you obtain:

=74-2(35)
=74-70
=4

4. Therefore, as you can see, the correct answer is: 4

At a hockey game a vendor sold a combined total of 110 sodas and hot dogs. The number of hot dogs sold was 42 less than the numb

jasenka [17]

76 sodas and 34 hot dogs were sold by the vendor.

Step-by-step explanation:

Given,

Total sodas and hot dogs sold = 110

Let,

x be the number of sodas sold

y be the number of hot dogs sold

According to given statement;

x+y=110 Eqn 1

y = x-42 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$x+(x-42)=110\\x+x-42=110\\2x=110+42\\2x=152$

Dividing both sides by 2

$\frac{2x}{2}=\frac{152}{2}\\x=76$

Putting x=76 in Eqn 1

$y=76-42\\y=34$

76 sodas and 34 hot dogs were sold by the vendor.
