Answer:
y=2x+2
Step-by-step explanation:
convert x-2y=7 into slope intercept form
then your new slope is the reciprocal of the original function then substitute
x and y values to find b.
To solve this, you will need to divide the payment by 4 if she is doing four of the same payments.
196 / 4 = 49
so she will pay $49 a month.

Answer:
3x = 50 - 10y
Step-by-step explanation:
Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,
So, total weight of 3 lb weights = 3x
And, the weight of 10 lb weights = 10y
Total weight of all his weights = 3x + 10y
According to the question,
Total weight = 50 lb,
⇒ 3x + 10y = 50
Or 3x = 50 - 10y
Which is the required equation.
Second option is correct.
