How do I solve it because it’s really difficult

dybincka [34]

The solution of the equation is x= 3 and y = 2

Step-by-step explanation:

Given,

-3x-4y = -17 and

-x-3y = -9

The system of equation can be rewritten as

3x+4y = 17 ------eq 1 and

x+3y = 9 ------ eq 2

To solve for x and y

Multiplying eq 2 by 3 we get,

3x + 9y = 27

or, 3x = 27-9y

Putting this value of x into eq 1 we get,

27-9y +4y = 17

or, -5y = 17-27

or, -5y = -10

or, y = 2

Now put y=2 in eq 2 we get,

x = 9 - 3(2)

= 3

Hence the solution is x = 3 and y = 2

In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what i

Inessa05 [86]

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

1. You need to apply the Pythagorean Theorem:

$c^{2}=b^{2}+a^{2}$

Where c is the hypotenuse and the legs are a and b.

2. Now, you must substitute the values given in the problem above and solve for b:

$(2b)^{2}=b^{2}+12^{2}\\4b^{2}=b^{2}+144\\4b^{2}-b^{2}=144\\3b^{2}=144\\b=\sqrt{\frac{144}{3}}\\b=6.92$

Therefore, the answer is: The value of b is 6.92
