4y + x = -12
4y +x (-x) = -12 (-x)
4y/4 = (-12 - x)/4
y = -3 - (x/4)
hope this helps
Answer:
(- 7, - 5 )
Step-by-step explanation:
Note: Consider the below figure attached with this question.
Given:
The ordered pair(6,y) is on line AC.
To find:
The y of this ordered pair.
Solution:
From the below figure it is clear that endpoints of AC are A(-7,-4) and C(1,4). So, equation of AC is
Subtracting 4 from both sides, we get
Thus, the equation of line AC is .
Put x=6 to find the y for the ordered pair (6,y).
Therefore, the value of y is 9.
Answer:
8
Step-by-step explanation:
8% is the annual interest rate. Since, only 3 month has been passed in the year end so, interest accrue of only 3 months.
8% is the interest of 12 months. So, 8%/12 is the interest rate of 1 month. But we want 3 month of interest rate. Multiplying (8%/12)*3, we will get 3 month interest rate.
Note, that we have substituted x with 8. Because, we need interest rate of 3 month, and 8 is the interest rate of 12 months.
