Answer:
Airpods=$150 iPhone=1050
Step-by-step explanation:
$1,200/8=150 150*7=1050
I might be wrong tho
Answer:
The second and fourth options
Step-by-step explanation:
A function is where one the inputs have only one output. In this case all we have to do is look at the x value (x,y) and see when it goes 1,2,3,4 and that means there are no repeating x and in that case each input has only one output. If you look at the other ones they have a repeating x and that means the input has two outputs and therefore it isn't a function.
Answer:
I think the answer is 322 because 1/2=50% which is equal to half
Plug in 1
and −1
to get two values of r(x)
which is linear. From there you can get what a,b
are in ax+b.
Since
f(x)=g(x)(x+1)(x−1)+r(x)
we have
f(1)=g(1)(1+1)(1−1)+r(1)=r(1)=−10
f(−1)=g(1)(−1+1)(−1−1)+r(−1)=r(−1)=16
We know the remainder is of degree 1
, so
r(x)=ax+b
and now we know,
r(1)=ax+b=a+b=−10
r(−1)=ax+b=−a+b=16
so, solve
a+b=−10
−a+b=16
which yields, a=−13
b=3
, so
r(x)=−13x+3
