One the first problem on finding the constant of <span> proportionality in this situation the answer is 2. Below is the solution:
constant = unit rate
unit rate = $2/ poung
K = 2
For the second question, the equation is the below:
T = 2p or y = 2x</span>
Answer: 12
Step-by-step explanation:
f(x)=(x+4) ^2 −25
to solve set equal to zero
0 =(x+4) ^2 −25
add 25 to each side
25 = (x+4) ^2
take the square root of each side
square root (25) =(x+4)
+- 5 = (x+4)
5 = x+4 -5 = x+4
subtract 4 from each side
1 =x -9 =x
Answer:
A) x=14
Step-by-step explanation:
hello :
6(x − 2) − 4x = 16
6x-12 -4x =16
2x-12=16
add 12 : 2x=16+12
2x= 28
x=28/2=14
