Answer:

solution set of the given system is (-5, -8)

Step-by-step explanation:

The system of the equation has been given as -8x - 7y = 96 -----(1)

and -3x + 5y = -25 -------(2)

Now we multiply equation 1 by 3 and equation 2 by 8

-24x - 21y = 288 ------(3)

-24x + 40y = -200 ------(4)

Now we subtract equation 3 from 4

(-24x + 40y) - (-24x - 21y) = -200 - 288

-24x + 40y + 24x + 21y = -488

61y = -488

y = -\frac{488}{61}

y = -8

Now we place y = -8 in the equation (2)

-3x + 5(-8) = -25

-3x - 40 = -25

-3x = 40 - 25

-3x = 15

x = -5

Therefore, solution set of the given system is (-5, -8)

The longer leg of a right triangle is 4cm longer than the shorter leg. the hypotenuse is 8cm longer than the shorter leg. find t
Alexeev081 [22]
Longer leg = x + 4

Shorter leg = x

Hypotenuse = x + 8


Using Pythagorean Theorem:

a^2 + b^2 = c^2

(x + 4)^2 + x^2 = (x + 8)^2

x^2 + 8x + 16 + x^2 = x^2 + 16x + 64

2x^2 + 8x + 16 = x^2 + 16x + 64

2x^2 +8x = x^2 + 16x + 48

2x^2 - 8x = x^2 + 48

x^2 - 8x = 48

x^2 - 8x - 48 = 0

You can complete the square from here or use the quadratic formula.

Completing the square:

x^2 - 8x = 48

x^2 - 8x + (-8/2)^2 = 48 + (-8/2)^2

x^2 - 8x + 16 = 48 + 16

(x - 4)(x - 4) = 64 or (x - 4)^2 = 64

x - 4 = +√64 OR x - 4 = -√64

x - 4 = +8 OR x - 4 = -8

x = 12 OR x = -4

However, you can't use negative 4 as a length because your length needs to be a positive.

So x will be 12.


Shorter leg: 12

Longer leg: 12 + 4

Hypotenuse: 12 + 8

N- 0.125= 4.1 what is N?
guajiro [1.7K]
Well, lets add 0.125 to 4.1.

We would get 4.225.

Finally we can check.

4.225-0.125= 4.1

How did we get it? What i did is I did the opposite. Instead of subtracting 0.125 I added it.

N= 4.225
