Answer:

=x2+x−6

Step-by-step explanation:

(x+3)(x−2)

=(x+3)(x+−2)

=(x)(x)+(x)(−2)+(3)(x)+(3)(−2)

=x2−2x+3x−6

=x2+x−6

Identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries for the given freque

Aleks [24]

Step-by-step explanation:

kindly find attached detailed information of the remaining information as requested for your reference

1. The lower class limit is the left number in the age column

i.e in the 25-34 the lower class limit is 25

2. The upper class limit is the right number in the age column

i.e in the 25-34 the lower class limit is 34

3. The class width is the difference between the class boundaries of a single class

class width = 34.5-24.5= 10

4. The number of individuals is= 29+34+16+3+5+1+2= 90

What is the inverse of the function of (x)=2^(x)+6

Elden [556K]

Answer:

Option D.

Step-by-step explanation:

To find the inversion of a function follow the following procedure

1) Replace x with y in the function and clear y

$y=2^{(x)} + 6$ ------> $x = 2^{(y)}+ 6$

$x-6 = 2^y$

$y = log_2(x-6)$

2) Check. The range of f(x) is the domain of $f^{-1}(x)$ .

So if f(a) = b, this means that $f^{-1}(b)$ = a.

$f(2) = 2^2+ 6 = 10$

$f^{-1}(x) = log_2(10-6) = 2$

Is fulfilled. Therefore $y=log_2(x-6)$ is the inverse of $f(x) = 2^{(x)} +6$

What is the image of 6, -7 after dilation by scale factor of 3 centered at the origin

earnstyle [38]

Answer:

(18,−21)

Step-by-step explanation:

Dilation: multiply each coordinate

(x,y)\rightarrow (3x,3y)

(x,y)→(3x,3y)

Dilations multiply by scale factor

(\color{red}{6},\color{blue}{-7}) \rightarrow (3\cdot \color{red}{6},3\cdot \color{blue}{-7})=\mathbf{(18,-21)}

(6,−7)→(3⋅6,3⋅−7)=(18,−21)
