Answer: 933
Step-by-step explanation: 11,023-10,090=933
Answer:
Slope is the change in y over the change in x. Just subtract and simplify the fraction.
Step-by-step explanation:
(-3 - 4)
______
(-2 - 6)
Answer:
1792
Step-by-step explanation:
given,
f (n) = 4 f (n - 1)
here,
f(2) = 4 f ( 2-1)
= 4 f ( 1 )
= 4. 7
= 28
then,
f(3) = 4 f ( 3-1)
= 4 f ( 2)
= 4. 28
= 112
again,
f (4) = 4 f ( 4-1)
= 4 f ( 3)
= 4.112
=448
at last,
f ( 5) = 4 f ( 5-1)
= 4 f ( 4)
= 4. 448
= 1792

We know that y=7x, so we just need tu put it into the 1st equation

So we found x. Now we can find y

Answer:
x=1, y=7; or (1;7)
