ANSWER

${f}^{ - 1} (x) = 4x - 3$

EXPLANATION

Given

$f(x) = \frac{x + 3}{4}$

Let

$y= \frac{x + 3}{4}$

Interchange x and y

$x= \frac{y + 3}{4}$

Solve for y,

$4x = y + 3$

y=4x-3

This implies that,

${f}^{ - 1} (x) = 4x - 3$

Simplify 3a(a^2-3a+4)-4(3a^3-2a^2)

bogdanovich [222]

Answer:

Step-by-step explanation:

3a(a²-3a+4)-4(3a³-2a²) = 3a³ − 9a² + 12a − 12a³ + 8a²

= (3a³ − 12a³) + (− 9a² + 8a²) + 12a

= −9a³ − a² + 12a

1.The sum of three consecutive numbers minus 12 is 75

Arte-miy333 [17]

Answer:

The answer is

One: 28, 29, 30

Two: 75,77

Step-by-step explanation:

One

Let the three numbers be (x - 1) , x , and x + 1

(x - 1) + x + (x +1 ) - 12 = 75 Remove the brackets

x - 1 + x + x + 1 - 12 = 75 Combine the like terms on the left

3x - 12 = 75 Add 12 to both sides

3x = 75 + 12

3x = 87 Divide by 3

x = 87/3

x = 29

Two

Let the first odd number = 2x -1

Let the second odd number = 2x + 1

2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.

4x + 18 = 170 Subtract 18 from both sides.

4x = 170 - 18 Combine like terms on the right

4x = 152 Divide by 4

4x/4 = 152/4

x = 38

2 * 38 - 1 = 75

2 * 38 + 1 = 77

The slope will always be next to X when the equation is in slope intersect form (y=mx+b). So the slope in that equation is -1/2.

The heart rate of 10 adults is measured and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121. Find the interquartile

zloy xaker [14]

The interquartile range of the data set is 21.

Given that the heart rate of 10 adults is measured and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121.

The interquartile range shows the extent of the middle half of the distribution. Quartiles segment any distribution, ordered from low to high, into four equal parts. The interquartile range (IQR) contains the second and third interquartile ranges, the central half of the dataset.

The value of quartile 1 is Q₁=90

The value of quartile 3 is Q₃=111

So, the interquartile range is

IQR=Q₃-Q₁

IQR=111-90

IQR=21

Hence, the interquartile range of the data set 83, 87, 90, 92, 93, 100, 104, 111, 115, 121 is 21.
