Answer:
(0, 7) is an ordered pair solution to 3x + y = 7
Step-by-step explanation:
Given the equation 3x + y = 7, find a solution (ordered pair).
There are an infinite number of possible solutions. Let's focus on just one:
Let x = 0. Then y = 7, and (0, 7) is an ordered pair solution to 3x + y = 7
Answer:
<em> = n² + 4n ; n = 11 </em>
Step-by-step explanation:
= 
[2 
+ (n - 1)d]
~~~~~~~~~
= 5
d = 7 - 5 = 2
= [ 2(5) + 2(n - 1)] = ( 8 + 2n ) = 4n + n²
<em> = n² + 4n</em>
n² + 4n = 165
n² + 4n - 165 = 0
(n + 15)(n - 11) = 0 ( n ≥ 0 ) ⇒ <em>n = 11</em>
Answer:
Yes, they are proportional.
Step-by-step explanation:
The ratio for Veronica's trail mix is 3:7
The ratio for Casey's trail mix is 27:63 <--- Simplify this number
27:63 simplified is 3:7, which means <u>these ratios are proportional.</u>

hope this helps :)
The answer is yes, every 5 dollars there is an extra 0.35$ tax so it’s a straight line which means that it is proportional
