Y intercept is -6
Y= 5x^2-X-6
Y= 5(0)^2-0-6
Y= 0-0-6
Step-by-step explanation:
Let the son's age be x and man be y
y=26+x
y=8+3x
x=9
Son's age is 9
To check for continuity at the edges of each piece, you need to consider the limit as 
approaches the edges. For example,
has two pieces, 
and 
, both of which are continuous by themselves on the provided intervals. In order for 
to be continuous everywhere, we need to have
By definition of , we have 
, and the limits are
The limits match, so is continuous.
For the others: Each of the individual pieces of 
are continuous functions on their domains, so you just need to check the value of each piece at the edge of each subinterval.
Answer:
not all rectangles are paralloelograms.
Step-by-step explanation:
The answer is D
if the legs are 5 and 4 cm the equation to find the hypotenuse would be 5^2+4^2=c^c
5 squared is 25 and 4 squared is 16 that gives you 41, normally you would square root the 41 but it gives you a decimal number
