Answer: uhh I don't get it but ima try it-

Step-by-step explanation:

Let the number be x.

Twice the number = 2x

Twice the number increase by 8 = 2x+8

Twice the number increase by 8 is 22

2x + 8 = 22

The solution to this equation will be as follows:

2x = 22 – 8

2x = 7

Divide both sides by the coefficient of x,that is 2 in this case:

2x/7 = 12/2  

So after you do that you get:

x = 21

Suppose the function of h is defined, for all real numbers as follows: (f) x = -3 if x is <) 3 if x is =0 -2 if x is > 0
V125BC [204]

Answer:

See explanation

Step-by-step explanation:

The question is not properly presented; I will answer this with the following similar question.

h(x) = -\frac{1}{3}x^2 + 4 --- x \ne 2

h(x) = -4 --- x= 2

Required

h(-5)\ \&\ h(2)

<u>Calculating h(-5)</u>

This implies that: x = -5

-5 \ne 2

So, we make use of:

h(x) = -\frac{1}{3}x^2 + 4

Substitute -5 for x

h(-5) = -\frac{1}{3} * (-5)^2 + 4

h(-5) = -\frac{1}{3} * 25 + 4

h(-5) = -\frac{25}{3} + 4

Take LCM

h(-5) = \frac{-25+12}{3}

h(-5) = -\frac{13}{3}

<u>Calculating h(2)</u>

This implies that: x = 2

2 = 2

So, we make use of:

h(x) = -4

Substitute 2 for x

h(2) = -4
