If you divide the first equation by 4, you get x+y =4, which is the same as Line B. In this case, the two lines coincide. Infinitely many solutions.
For this seq An = -62 +8 (n-1)
Thus the 11th term = -62 + 8×10 = 18
Answer:
she is 9.6 feet below sea level
Step-by-step explanation:
shes below sea level so its a negative number -22
and ascend means to climb or go up so its a positive number +12.4
-22 + 12.4 = -9.6
since the outcome is negative shes still below sea level
A(n)=-10 + (n-1)4
a(n)= 10 + 4n -4
a(n)=4n+6
W = p(y - z)
Divide each side by p
w/p = y - z
Subtract y
w/p - y = -z
Negate each side
(-w/p) + y = z
