The sum of two numbers is 27. One number is 3 more than the other. Write and solve a system of equations to find the two numbers

givi [52]

X + y = 27
x = y + 3

y + 3 + y = 27
2y + 3 = 27
2y = 27 - 3
2y = 24
y = 24/2
y = 12

x = y + 3
x = 12 + 3
x = 15

ur numbers are 12 and 15

Which of the following is an odd function?

Inga [223]

Answer:

f(x)=-x

Step-by-step explanation:

An odd function is symmetric with respect to origin.

It has the property,

$f( - a) = - f(a)$

The only function that is symmetric about the origin is:

$f(x) = - x$

Now let's put x=-a, to get:

$f( - a) = - - a = a$

Also

$f(a) = - a$

We can see that:

$f( - a) = - f(a) = a$
