Answer:
The interest when rate is 5.2% is $48.88
Step-by-step explanation:
if interest (I) varies directly as interest rate (R)
Then
I ∝ R
I=cR
c= constant
if interest is $47 when interest rate is 5%
47 =.05c
c = 940
if interest rate is 5.2% then
I = 940 x .052
=48.88
=$48.88
Since the first equation says y= x-4, substitution that for the y value in x + y = 6
x + x - 4 = 6
add up the x’s to get 2x - 4 = 6
add 4 to both sides to get 2x = 10
divide both sides by 2 to get x = 5
the x value is 5
then, to figure out the y value, substitute 5 for the x value in y = 5-4
the y value is 1
final answer: x = 5 and y = 1
hope this helped!!
Dude that’s the answer....hellloooo
1.
If we are given 2 points A(a, b) and B(c, d),
the midpoint M, of segment AB has coordinates:

2.
We are given the points A(2, 3) and B(10, 3)
the midpoint of AB, is given by the above formula:

3.
Remark, since the segment is horizontal, that is the y-coordinate of both points is 3, the y coordinate of the midpoint will also be 3.
While the x coordinate is still found by

Answer: (6, 3)
