Solve the following system of equations using substitution.

ollegr [7]

To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.

$5x - 4y = -3$

$5x - 4(3x-5) = -3$

$5x -12x+20=-3$

$-20$ $-20$

_______________

$5x-12x=-23$

$-7x=-23$

___ ____

$-7$ $-7$

$x=3.29$ (rounded)

Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.

$y = 3x-5$

$y = 3(3.29)-5$

$y = 9.87-5$

$y = 4.87$

So, your final answer would be (3.29, 4.87).

Find the length of the third side. If necessary, write in simplest radical form. 2741 8

ki77a [65]

Answer:

10

Step-by-step explanation:

Let the missing side be 'x'.

Using Pythagorean Theorem, we can find the missing side.

x² + 8² = (2√41)²
x² + 64 = 4(41)
x² + 64 = 164
x² = 100
x = 10

Please answer this. i’ve asked 3 questions of this same thing bc people don’t even answer them, i’ll give brainliest to whoever

Stels [109]

We will be using the formula: Speed = Wavelength * Frequency

1. Given: Wavelength = 5 m and Frequency = 2 Hz

Speed of the wave = Wavelength * Frequency

Speed of the wave = 5 * 2

Speed of the wave = 10 m/s

__________________________________________________________

2. Given: Speed of the wave = 100 m/s and Frequency= 1000 Hz

Wavelength = Speed / Frequency

Wavelength = 100 / 1000

Wavelength = 0.1 m

__________________________________________________________

3. Given: Speed of the Wave = 25 m/s Wavelength = 5 m

Frequency = Speed / Wavelength

Frequency = 25 / 5

Frequency = 5 Hz
