Answer:
$2.40
Step-by-step explanation:
5.45 + 2.15 = 7.60
10 - 7.60 = $2.40
Plugging -6 in for x, we get -2sqrt(-6-7+1)=sqrt(something negative) which is clearly not possible.
Plugging -6 in for f(x), we get -6=-2sqrt(x-7+1) and 3=sqrt(x-7+1). Squaring both sides, we get 9=x-7+1 and by adding both sides by 6 we get 15=x, therefore having (15,-6) and proving that -6 is in the range, but not the domain (B)
I believe it’s because b=(1+r)
Answer:
x(x+2)(x-2)(x+1)(x-1)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula,]a^{2} - b^{2} = (a+b)(a-b), where a = x and b = 2.
Answer:
10
Step-by-step explanation:
substitute -3 in for x
f(-3)=(-3)²+1=
9+1=10
(You can ignore the g(x) part - it has nothing to do with this question.)
