Answer:
<h2>C. infinity many</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope
b - y-intercept
If the equations have the same slopes and the same y-intercepts, then the system of equations has infinitely many solutions.
If the equations have the same slopes and differences of the y-intercepts, then the system of equations has no solution.
If the equations have different slopes, then the system of equations has one solution.
We have
→ m = -6 and b = 3
and
![30x+5y=15](https://tex.z-dn.net/?f=30x%2B5y%3D15)
convert to the slope-intercept form:
<em>subtract 30x from both sides</em>
<em>divide both sides by 5</em>
→ m = -6 and b = 3
<em>We have the same slopes and the same y-intercepts.</em>

</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
order of PEMDAS
- parentheses
- exponent
- multiplication or
- division
- addition or
- substraction
<h3>let's solve:</h3>
simplify multiplication:
![\displaystyle \: \sqrt{ {65}^{2} }](https://tex.z-dn.net/?f=%20%20%5Cdisplaystyle%20%5C%3A%20%20%5Csqrt%7B%20%7B65%7D%5E%7B2%7D%20%7D%20)
use
to simplify:
![\displaystyle \: = {65}^{2 \times \frac{1}{2} } \\ = {65}^{ \cancel{ \: 2 }\times \frac{1}{ \cancel{ \: 2}} } \\ = {65}^{1}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5C%3A%20%20%3D%20%20%7B65%7D%5E%7B2%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%20%5C%5C%20%20%20%3D%20%7B65%7D%5E%7B%20%5Ccancel%7B%20%5C%3A%202%20%7D%5Ctimes%20%20%5Cfrac%7B1%7D%7B%20%5Ccancel%7B%20%5C%3A%202%7D%7D%20%7D%20%20%5C%5C%20%20%20%3D%20%7B65%7D%5E%7B1%7D%20)
as we know x¹=x
therefore our final answer is
- <em><u>6</u></em><em><u>5</u></em>
