Step-by-step explanation:
![\to \dfrac{5}{7} = \dfrac{4x}{83}](https://tex.z-dn.net/?f=%20%5Cto%20%20%5Cdfrac%7B5%7D%7B7%7D%20%20%3D%20%20%5Cdfrac%7B4x%7D%7B83%7D%20)
By cross multiplication,
→ 83(5) = 4x(7)
→ 415 = 28x
<h3>→ 415/28 = x</h3>
Answer:
Depending on what you're looking for: 5 or -5/2
Step-by-step explanation:
If non-function, count the height in which it covers: 5
If function, find slope (rise over run): -5/2
The first one is b. The second one is d. Sorry if I’m wrong :(
Answer:
x=
7/3
x=-4
Step-by-step explanation:
Use the quadratic formula
a= 3, b=5, c=-28
-5± ![\sqrt{5^2-4*3(-28)}](https://tex.z-dn.net/?f=%5Csqrt%7B5%5E2-4%2A3%28-28%29%7D)
