Answer:
The common difference of the progression is 3.
Step-by-step explanation:
Given:
First term of the AP = (a) = -8
Ratio of 7th and 9th term = 5:8
So,
General term of an AP, Tn= a+(n-1)d
Where 'd' is the common difference.
equation...(i)
equation...(ii)
According to the question.
⇒ 
...cross-multiplying the terms.
⇒ 
⇒ 
⇒ 
...subtracting 40d and adding 64 both sides.
⇒ 
⇒ 
...dividing both sides with 3.
So the common difference of the progression is 'd' = 3.
The value of x=3
is x-3=y
f=x-3
Answer:
The forth one
Step-by-step explanation:
g(z)=z+4
z=o g(z)=4
g(z)=0 z=-4
1) First minus the sole number(in this case 10) on the side that the variable(x) is on and subtract it also the sum(you will get x/4=4). Second, multiply the fraction by the denominator, in this case 4, and multiply the sum as well. You will now end up with the sum equals x (x=16 in this case)
