Answer:
The first table.
Step-by-step explanation:
Every single time, the x is being multiplied by 3 to get the y, and that means its proportional. Also, the second one is for sure NOT proportional
6) √72= √3*25= √3*2*12= √3*3*2*2*2 =3*2√2 =6√2
(just break down the numbers until they are prime numbers. )
8) √8=2√2
10) √175= 5√7
12) √192= 8√3
14) √32= 4√2
I hope this helps you
y=7 x=7 m = -4
y=mx+b
7= -4.7+b
b=35
y= -4x+35
Answer:
45 miles
Step-by-step explanation:
Use pythagorean theorem:
2x + 3y = 40
+
-2x + 2y = 20
___________ Adding both equations
0x + 5y = 60
____________
5y = 60
y = 60/5 = 12
y = 12.
Since we have gotten y =12, and the only option with that is option D.
So we don't have to solve for x.
The answer is D.
