Answer:
g(x) = (5x + 3)/ x - 7
Step-by-step explanation:
Let g(x) = y
y = (7x + 3)/x - 5
Make x the subject
xy - 5y = 7x + 3
xy - 7x = 5y + 3
x(y - 7) = 5y + 3
x = (5y + 3)/ y - 7
Therefore, the inverse of the function = (5x + 3)/ x - 7
if 1 inch is added, you would add 2 inches to to each side of rectangle.
You would have: W+2, and, L+2,
Now let W+2 = x and, L+2 = y
Total area = x*y=M
If 1 inch is added again, like above you add 2 inches to both sides, you would then have:
(x+2)(y+2)=M+52;
xy+2x+2y+4=M+52;
xy=M
2x+2y=48
x+y=48/2=24
Now solve :
W+2+ L+2=24
W+L=20
The perimeter is 2(W+L)=20*2 = 40 inches.
Answer:
7.5 bags of dog food in 6 months
Step-by-step explanation:
(0.5)(6) = 3 bags for the his smaller dog (0.75)(6) = 4.5 bags for his larger dog... now add 3 + 4.5 and you get 7.5 total bags
Answer:
slope = m = (0--3)/(14--4) = 3/18 = 1/6
y=mx + b
y =(1/6)x + b
0= (1/6)14 + b
b = - 14/6 = - 7/3
y = (1/6)x - 7/3
or
6y-x = -14
Step-by-step explanation:
