X=2
And z = 117
Hope it helps Ig
Answer:
5
Step-by-step explanation:
it can be found in two ways
f(n)-f(n-1) is common difference of the sequence.
knowing f(n) = f(n-1) + 5
f(n)-f(n-1)=5
so 5 is difference of the sequence.
other method is
f(1)=4
f(2)=?
f(n)=f(n-1)+5 n=2
f(2)=f(2-1)+5
f(2)=f(1)+5
f(2)=4+5=9
f(2)-f(1)=9-4=5
so 5 is difference of the sequence.
Answer:
You would end up with X= -2, y= 2
And they would intersect at point (-2,2) on a graph :)
Answer: B) y-4=6(x-1)
Substitute the point into each equation
A: y-4=6(x+1)
4-4=6(1+1)
4-4=6+6
0=12
This is false so it is not the answer
B: y-4=6(x-1)
4-4=6(1-1)
4-4=6-6
0=0
This is true so this is the answer, but I will continue solving just to check
C: y+4=6(x-1)
4+4=6(1-1)
4+4=6-6
8=0
This is false so it is not the answer
D: y+4=6(x+1)
4+4=6(1+1)
4+4=6+6
8=12
This is not true so it is not the answer
Your answer becomes b, the only true equation! Hope this helps comment below for more questions :)
