What value of x makes the equations true? show work
Answer:
D. y = -5/7x + 5
Step-by-step explanation:
5x + 7y = 35
-5x -5x
7y = 35 - 5x
/7 /7 /7
y = 35/7 - 5/7 x
y = 5 - 5/7x
Answer:
![\displaystyle x = \sqrt{y^2 + z^2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%20%3D%20%5Csqrt%7By%5E2%20%2B%20z%5E2%7D)

<em>Identify</em>
![\displaystyle x^2 = y^2 + z^2](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%5E2%20%3D%20y%5E2%20%2B%20z%5E2)
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Equality Property] Square root both sides:
![\displaystyle x = \sqrt{y^2 + z^2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%20%3D%20%5Csqrt%7By%5E2%20%2B%20z%5E2%7D)
