Given r(x) = x square +2x -1 and s(x) = x-1 what is the value of r(s(3))

Amanda [17]

Answer:

$r(s(3))=7$

Step-by-step explanation:

we have

$r(x)=x^{2} +2x-1$

$s(x)=x-1$

we know that

The function composition is equal to

(r ∘ s )(x) = r(s(x))

In the function r(x) substitute the variable x by the function s(x)

$r(s(x))=(x-1)^{2} +2(x-1)-1$

For x=3

substitute the value of x=3 in the function composition

$r(s(3))=(3-1)^{2} +2(3-1)-1$

$r(s(3))=(2)^{2} +2(2)-1$

$r(s(3))=4+4-1$

$r(s(3))=7$

What is 12a equal to if 4a plus 6b = 10 and 2a-4b=12?

hram777 [196]

12a=x
4a+6b=10
2a+3b=5
2a-4b=12
a-2b=6
2a+3b+1=a-2b
a+5b+1=0
a=-1-5b

2(-1-5b)+3b=5
-2-10b+3b=5
-2-7b=5
-7b=7
7b=-7
b=-1

-1-5*-1=a
-1+5=a
4=a

4*12=48
12a=48

Hope this helps :)
