Answer: an equation that has one term which is nameless and squared also no term which gets raised to higher power.
Step-by-step explanation:
The answer would be option B "he was given $50 for his birthday."
Here is how:
Y=
^
Y equals the amount of money in the account.
75$+50$=
75x represents the amount of money he DEPOSITS which is in the question.
So if he deposits 75$ a week (which represents X) and he adds 50$ to it which means he has 50$ to begin with which means he got 50$ for his birthday.
Also....
Because 75x already represents X therefore it wouldn't be options A, C or D.
Hope this helps!

12.
y = kx
8 = -4k
so k = -2
y = -2x
y = -2 (7)
y = -14
13.
y = kx
15 = 6k
so k = 15/6 = 2.5
y = 2.5x
y = 2.5 (7)
y =17.5
14.
y = kx
3 = 9k
so k = 3/9 = 1/3
y = 1/3x
y = 1/3 (7)
y =7/3
15
y = kx
-4 = 4k
so k = -4/4 = -1
y = - x
y = - (7)
y = -7
16.
Yes. y varies directly with x
slope = (3+6)/(2+1) = 9/3 = 3
y = mx + b
-6= 3(-1) + b
b = -6 + 3 = -3
equation y = 3x -3
17.
Yes
slope = (2.5 - 7.5)/(-1+3) = -5/2 = -2.5
y = mx + b
7.5= -2.5(-3) + b
7.5 = 7.5 + b
so b = 0
equation
y = -2.5x
Answer:
Step-by-step explanation: square root both numbers so 55 square root is 7.41 and he square root of 16 is 4 now divide them so 7.41 divided by 4 = to 1.85 there fore 1.85 is ur answer
