1. Determine f -1 (x) for each of the given functions
f (x) =2x-3
2. Determine f -1 (x) for each of the given functions
f (x) = x over x+2
Step-by-step explanation:
1) f(x) =2x -3
y=2x - 3
x= 2y -3
2y =x + 3
y = x+3 over 2
f(x)^-1 = x+3 over 2
2) f(x) = x /x+2
y= x / x+2
y / y+2 = x
y = (y+2)x
y= xy +2x
y -xy = 2x
y( -x +1) = 2x
y= 2x over -x + 1
f(x)^1 = 2x over -x + 1

Step-by-step explanation:
Use the figure below to find the length of the midsegment.
68
54
4x + 6
68
54
4x + 44
Answer:
38
Step-by-step explanation:
4x + 6 = ½(4x + 44) (midsegment theorem)
Multiply both sides by 2
2(4x + 6) = 4x + 44
8x + 12 = 4x + 44
Collect like terms
8x - 4x = -12 + 44
4x = 32
Divide both sides by 4
x = 8
Length of midsegment = 4x + 6
Plug in the value of x
Midsegment = 4(8) + 6
= 32 + 6
= 38

In a baseball game, Elena scored twice many pints as Tyler.Tyler scored four points fewer than Noah, and Noah scored three times as many points as Mai. If Mai scores 5 points, how many did Elena scored?
Answer:
Elena scored 22 points.
Step-by-step explanation:
Mai scored 5 points, and Noah scored three times as many. This means Noah scored 15 points and if Tyler scored four points fewer, he scored 11 points. If Elena scored twice as many as Tyler, she scored 22.
Expand and simplify
2(4x + 3) + 4(3x - 1)
[tex]2(4x + 3) + 4(3x - 1)[/tex]
[tex] = (8x + 6) + (12x - 4)[/tex]
[tex] = 8x + 6 + 12x - 4[/tex]
[tex] = (8x + 12x) + (6 - 4)[/tex]
[tex] = 20x + 2[/tex]
Answer:
8x+6+12x-4= 0
20x+2= 0
20x=-2
20x/20= -2/20
x= -1/10
Solve the system of equations. − 3 x + 2 y = 56 − 5 x − 2 y = 24 −3x+2y=56 −5x−2y=24
Step-by-step explanation:
-3x + 2y = 56
+ (-5x - 2y = 24)
=> -8x = 80, x = -10.
Therefore -3(-10) + 2y = 56, 30 + 2y = 56, y = 13.
Hence x = -10 and y = 13.
Answer:
x = -10 and y = 13.

Estimate the square root of 5 to the nearest tenth
Answer:
Step-by-step explanation:
It's about +- 2.2. It equals 2.236067977 but can be rounded to 2.2. When you square root, the answer could be positive or negative.
The square root of 5 to the nearest tenth is 2.2.
We have to find out the square root of 5 that should be the nearest tenth.
So, the following procedure should be followed:
[tex]= \sqrt{5}\\\\= 2.2360679[/tex]
= 2.2
Therefore we can conclude that the square root of 5 to the nearest tenth is 2.2.

24/18 = 4/3
4/3 * 100 = 133 1/3 %
Missed that 1/3
Answer:
133.33%Step-by-step explanation:
24 is x% of 18, solving for x:
x = 24/18*100% = 133.33%How do you work this problem? 10x2 +25x
Answer:
x=-5/2,0
Step-by-step explanation:
It is solved by first factorizing it
10x²+25x=5x(2x+5)=0
Finding the zeros
5x=0x=0/5=0
2x+5=0
x=-5/2
Therefore x is -5/2 or 0

The Fruity Tooty company claims that the population proportion for each of its five flavors is exactly 20%. Jane counts 92 red candies in a 400-count sample.
what is the value of the z-test statistic? Answer choices are rounded to the hundredths place.
Answer:
86.96%
Step-by-step explanation:
s2 = a2 / n
a2 = 4.34782608696 if just 1/1 flavour 400/400 was the case.
We are asked to account for 5 flavours 4.34782608696/5
Z test was 0.86956521739 for red candies
s2 = a2/n
a2 = 0.86956521739/1
s2 = 0.86956521739/1
s2 = 0.87 hundredth place
Percentage 0.86956521739 x 100 = 86.96% to 100th place
