Answer:
Could be an equilateral triangle
Step-by-step explanation:
I hope I'm right, sorry if I got it wrong but I hope this helped!
1.) 5 (3a + 4c = 67)
2.) -3 (5a + 6c = 106)
1.) 15a + 20c = 335
2.) -15a - 18c = -318
_____________________
2c = 17
divide both sides by 2
c = £8.5
substitute c for 8.5 to find a
3a + 4 * 8.5 = 67
3a + 34 = 67
subtract 34 from both sides
3a = 33
divide both sides by 3
a = <span>£</span>11
Y=square root of x
All the others would be a straight line with an unchanging slope (meaning they're linear). Y=rootx is not linear.
I hope this Helps!
