-7 times -8 is 56 and -40 divided by 10 is -4
Answer:
a) Here we have:
"In Family A, the youngest child is 7 years younger than the oldest, who is 18"
Let's define:
Y = age of the youngest child.
O = age of the oldest child.
Then we know that:
Y = O - 7
O = 18
Then we can replace the second equation into the first one:
Y = 18 - 7 = 11.
b) Here we have:
"In Family B, the middle child is 5 years older than the youngest child."
Let's define:
Y = age of the youngest child.
M = age of the middle child.
Here we have only one equation:
M = Y + 5.
Answer:
Line means going on upto point but line segment means limited line
Make use of the known limit,
We have
since 
, and the limit of a product is the same as the product of limits.
is continuous at 
, and 
. The remaining limit is also 1, since
so the overall limit is 1.
