<em>A</em><em>nswer</em> : 6 keychains
Step-by-step explanation:
there are 12 inches in 1 feet
so,there 36 inches of string
Mia needs 6 inches for each keychain.
36/6 is 6.
so in total there's 6 keychains being made
F(x)= 2/(x+1) and g(x)= -x2-12 => f(-7)= ? , g(2.5)= ?, g(f(- 0.5))= ?
In the expression of the function f(x) we will replace instead of x the number in bracket (-7) => f(-7) = 2/(-7+1)= 2/-6 = - 1/3
In the expression of the function g(x) we will replace instead of x number in bracket (2.5) => g(2.5) = - (2.5)squared -12= - 6.25 -12= - 18.25
Expression f(g(x)) or g(f(x)) is multiplication (composition) of the reflecting of functions f and g. We will do this in the following way => g(f(x))= g(2/(x+1))= -(2/(x+1))2 - 12= -(4/(x+1)2) -12= -4-12(x+1)2/(x+1)2=> we will replace instead of x the number in bracket (-0.5) or (-1/2) => g(f(-1/2) = -4-12((-1/2)+1)2/ ((-1/2+ 1)2= -4-12(1/2)2/(1/2)2=-4-12*(1/4)/(1/4)= (-4-3)/(1/4)=-28
Eaisier way => f(-1/2)=2/((-1/2)+1)=2/(1/2)= 4 g(4) -(4)2-12 = -16-12= -28
In this problem, you are just being asked the distance between the numbers on the number line.
Example:
X=5, A= - 5
Count the spaces in between the 2 numbers... 5 is on the positive side, any number on the right of a number line is a positive number, and any number on the left of a number line is a negative.
so if you count down from positive 5 to 0, you have jest then moved 5 spaces backwards... now move back 5 again into the negative side, now you should have moved a total of 10 spaces coming from positive to negative.
Answer:
i cant see teh expressions but..
Step-by-step explanation:
341+983=1324
1324 *divided by* 36

2 5/6÷ 1/3= 17/2× 3= 17/2 = 8 1/2
