algebra
PEMDAS

<h3>let's solve:</h3>

given function:

$\quad \rm\: f(x) = - 2x +8$

when x is 0

$\sf \:f(0) = - 2.0 + 8$

simplify multiplication:

$\sf f(0) = 8$

when x is 3

$\sf f(3) = - 2.3 + 8$

simplify multiplication:

$\rm \: f(3) = - 8 + 8$

add:

$\rm \: f(3) = 0$

when x is 6

$\quad \rm\: f(6) = - 2.6 +8$

simplify multiplication:

$\quad \rm\: f(6) = - 12 +8$

simplify addition:

$\quad \rm\: f(6) = -4$

when x is 9:

$\quad \rm\: f(9) = - 2.9 +8$

simplify multiplication:

$\quad \rm\: f(9) = - 18 + 8$

simplify addition:

$\quad \rm\: f(9) = - 10$

Consider the following data values. 25 18 negative 9 14 32 negative 11 a) Calculate the mean. b) Calculate the median. c) Det

soldier1979 [14.2K]

Answer:

There is no mode in the set

B. Because the mean is less than the median comma this distribution's shape is left dash skewed.

Step-by-step explanation:

Data set = {25, 18, -9, 14,32}

We find sum = 80 hence mean = 80/5 = 16

No mode since nothing is more repeated

Median is the middle entry after arranging in ascending order = 18

a) x bar=16

b) median = 18

c) mode is nil

Here median - mean >1

so negatively skewed

There is no mode in the set

B. Because the mean is less than the median comma this distribution's shape is left dash skewed.

Evaluate 1/2a^-4b^2 for a=-2 and b=4<br> A) 2<br> B) 1/2<br> C)3<br> D)4

shepuryov [24]

Answer:

The answer to your question is: letter B) 1/2

Step-by-step explanation:

Data

a = -2

b = 4

Equation

(1/2)a⁻⁴b²

Substitution

= (1/2)(-2)⁻⁴(4)²

= (1/2) (1 /2⁴)(4)²

= 1/2 (1/16) (16)

= 16 / 32

= 1 / 2

In segment AC, the midpoint is B. if segments AC = 5x-9 and AB= 2x what is the measure of AC? Can you show their work on paper o

vodka [1.7K]

Answer:

The answer to your question is: AC = 36

Step-by-step explanation:

Data

Segment AC with midpoint = B

AC = 5x - 9

AB = 2x

AC = ?

Process

total length = AC but B is the midpoint so AB + AB = CA

2AB = CA

Substitution 2(2x) = 5x - 9

4x = 5x - 9

Solve for x 4x - 5x = -9

-1x = -9

x = -9/-1

x = 9

Finally, AC = 5x - 9

= 5(9) - 9

= 45 - 9

= 36

ratelena [41]

Answer:

B(m)=A(m)-D(m)

B(m)=176m

Step-by-step explanation:

we are given

Walking on his own, the distance, D, in feet, that Roberto can cover in M, minutes is given by the function

D(m)=264m

When he walks on the moving sidewalk at the airport, the distance, A, in feet, that he can cover in m m minutes is given by the function

A(m)=440m

B is the distance, in feet, that Roberto would travel on the moving sidewalk in m minutes if he were standing still

moving sidewalk distance = standstill distance + walking distance

A(m)=D(m)+B(m)

so, we get

B(m)=A(m)-D(m)

now, we can plug values

B(m)=440m-264m

B(m)=176m
