Answer:
x=3
Step-by-step explanation:
1/2(2-4x)+2x=13
1-2x+2x=13
4x=13-1
x=12/4
x=3
Answer:90 degree
Step-by-step explanation:
Measure its length.
-1(x+ and -(x+. because -x is same as -1
Answer:
4
Step-by-step explanation:
List all the factors of both numbers:
32: 1, 2, 4, 8, 16, 32
60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Now we look for the greatest number that is a factor of both 32 and 60.
Answer: 4
Answer:
The rate of change of relationship 'b' is 2.5 times greater than the rate of change of relationship 'a'
Step-by-step explanation:
The given parameters are;
The function representing relationship 'a' is y = 9·x
Some values of relationship 'b' are;
(0, 0), (3, 34.5), (5, 57.5), and (8, 92)
For direct proportionality of relationship 'b' we have;
y = k₂·x
∴ k₂ = y/x
∴ k₂ = 34.5/3 = 23/2
57.5/5 = 23/2
92/8 = 23/2
k₂ = 23/2
Therefore, the direct proportionality relationship of relationship 'a' is y = 9·x
∴ k₁ = 9
Therefore, the rate of change of relationship 'b' is k₂ - k₁ = (23/2) - 9 = 2.5 times greater than the rate of change of relationship 'a'.
