Answer:
D. f(x) = 2x - 8
Step-by-step explanation:
What you do is you take the x number and but it into the x spot.
f(x) = 2x Put 5 into the x
2(5) = 10 does not equal 2.
f(x) = x -3 Put 5 into the x
5 - 3 = 2, but if you plug a different x into it, it doesn't work.
D. f(x) = 2x - 8 is your answer.
It's absolutely correct..............
Answer with explanation:
x=the number of boxes containing red pens and
y = the number of boxes containing blue pens.
The expression which describes the number of red pen and blue pen in Boxes is
= (12 x-10)+(10 y-5)
The equivalent expression are
1.By Adding like terms
=12 x +1 0 y -10 -5
=12 x +1 0 y -15
or Using Associative Property of addition of three numbers which is
⇒a+(b+c)=(a+b)+c=(a+c)+b
= 10 y +12 x -15
or
= -15 +10 y +12 x
or
= 12 x -15 +10 y
The answer is 28.26
work:
Equation for area of circle: pi*radius squared
the radius of the circle is 3
3 squared is 9
9 times 3.14 is 28.26
Let, the number of books on Monday = m
On Tuesday = 2m
On Wednesday = 2m - 6
Equation: m + 2m + (2m - 6) = 19
You can solve it:
5m = 19 + 6
m = 25/5
m = 5
In short, He sold 5 books on Monday
Hope this helps!
