Answer:
-mx+y =b
Step-by-step explanation:
y = mx+b
We want to solve for b
Subtract mx from each side
y -mx = mx-mx +b
y -mx =b
We usually have the x term come first
-mx+y =b

8y = 23 + 3x divided by 8: divide ALL numbers by 8
8y/8 is y
23/8 is 23/8
3x/8 is 3/8x
Therefore, the answer would be;
y = 23/8 + 3/8x, which is the same as y = 3/8x + 23/8
Given :
Interest rate , r = 4 %.
To Find :
The APY .
Solution :
APY is given by :
Here , r is compound interest and n is number of time compounded .
So ,
Therefore , APY is 30.57 % .
Hence , this is the required solution .
Answer:
(a) 27 degrees (nearest degree)
(b) 17.9 m (to one decimal place)
Step-by-step explanation:
Wow, that's along ladder, perhaps for the firemen!
From diagram,
(a)
sin(x) = 9 / 20 = 0.45
x = arcsin(0.45) = 26.74 degrees
(b)
height of wall ladder reaches
h = 20*cos(x) = 20*cos(26.74) = 17.86 m
