Answer:
A = 11, B = 25/3, C = -1
Step-by-step explanation:
A linear function has the form:
f(x) = ax + b
(1)
f(3) = 8a + b = 8
f(5) = 5a + b = 9
Using the last 2 equations we can solve for 'a' and 'b'.
8a + b = 8 | 5a + b = 9
We multiply the second one by -1:
8a + b = 8 | -5a -b = -9
And then we add them together:
3a = -1
a = 
We then solve for 'b':
5a + b = 9
5(-1/3) + b = 9
b = 9 + 5/3
b = 32/3 = 
.
We then use this to find A, B, C.
f(x) = (-1/3)x + 32/3
(2)
f(A) = -A/3 + 32/3 = 7
(3)
f(7) = -7/3 + 32/3 = B
25/3 = B
(4)
f(C) = -C/3 + 32/3 = 11
Answer: Alright, I did UnU
Answer:
l = 60 yd; w = 30 yd
Step-by-step explanation:
We have two bits of information
(a) The perimeter of the rectangle
The formula for the perimeter of a rectangle is
P = 2l + 2w
P = 180 yd Insert into the formula
(1) 2l + 2w = 180
===============
(b) The length-to-width ratio
(2) l = 2w
Substitute the value of l from Equation (2) into Equation (1)
2×(2w) + 2w = 180
===============
Solve for w
4w + 2w = 180 Combine like term
s
6w = 180 Divide each side by 6
w = 30 yd
===============
Solve for l
Substitute the value for w into Equation (1).
2l +2×30 = 180
2l +60 = 180 Subtract 60 from each side
2l = 120 Divide each side by 2
l = 60 yd
The field is 60 yd long and 30 yd wide.
===============
<em>Check</em>:
P = 2×60 + 2×30
P = 120 + 60
P = 180 yd
Also
60 = 2 × 30
60 = 60
