Answer:
m = -3/5
Step-by-step explanation:
since both lines are given as "parallel", they will have the same slope, so we only need to solve for one.
we will put this equation into slope-intercept form to find the slope
3x + 5y - 16 = 0
3x + 5y = 16
5y = -3x + 16
y = -3/5x + 16/5
m = -3/5
I think she's wrong because she the real answer is an interest rate of 6 but she's thinking wrong so she's rethink her answer I hope I helped u
At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawls, each in the same amount.
Let x be the amount of one of Derek's withdrawals
Each of John's withdrawals was $5 more than each withdrawal that Derek made.
x + 5 is t the amount of one of John's withdrawals
Derek made 7 withdrawals
So amount withdraw 7 times = 7x
John made 5 withdrawals
So amount withdraw 5 times = 5(x+5)
Both Derek and John withdrew the same amount of money in the end
(A)7x = 5(x+5)
(B) Solve for x
7x = 5x + 25
Subtract 5x from both sides
2x = 25
Divide by 2
x = 12.5
(C) check your solution
we plug in 12.5 for x in 7x= 5x + 25
7(12.5) = 5(12.5) + 25
87.5 = 62.5+ 25
87.5 = 87.5
(D) Each brother withdrawal 87.5 dollars
X=3 so
3^2= 9
2*3= 6
y= 9 + 6
y= 15
