Answer:
x = 1
Step-by-step explanation:
6(x+4)=30 (divide both sides by 6)
(x+4) = 30/6
x+4 = 5 (subtract 4 from both sides)
x = 5 - 4
x = 1
Answer:
The rate of change is 0.08 and the initial value is 24.
Step-by-step explanation:
1. You have the following formula:
2. It has the form of a equation of the line, which is:
Where 
is the slope, which gives the rate of change and 
is the y-intercept (The initial value, when 
)
3. Therefore, the rate of change of the given formula is:
4. And the initial value is:
25.2:360 ::x:5100
Or 25.2 x ------=----- then cross multiply, 360x=5100*25.2
Answer:
For line j to be parallel to line k, then x has to be equal to 0
Step-by-step explanation:
if line j is parallel to line k, then the two angles are equal.
They are equal because they would be alternate angles and alternate angles are equal in value
Thus,
3x + 10 = 5x + 10
5x-3x = 10-10
2x = 0
x = 0
