Answer:

Step-by-step explanation:

y = kx ; k = [tex]\frac{y}{x}[/tex]

~~~~~~~~~~

(a). 139.8 = k × 12

k = 139.8 ÷ 12 = 11.65 ⇒ Kelly earns $11.65 per hour

y = 11.65x

(b). y = 11.65 × 40 = 466

Kelly's paycheck when she works 40 hours is $466.00

The graph shown represents an absolute function.

The equation of the graph is [tex]\mathbf{y = -\frac 12|x|}[/tex]

Considering the straight on the right, we have the following points

[tex]\mathbf{(x,y) = (0,0) (4,-2)}[/tex]

Start by calculating the slope (m)

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 -x_1}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{-2 - 0}{4-0}}[/tex]

[tex]\mathbf{m = \frac{-2 }{4}}[/tex]

Simplify

[tex]\mathbf{m = -\frac{1}{2}}[/tex]

So, the slope of the line is -1/2

The equation is then calculated as:

[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]

This gives

[tex]\mathbf{y = -\frac 12(x -0) + 0}[/tex]

[tex]\mathbf{y = -\frac 12(x)}[/tex]

Represent x as an absolute value

[tex]\mathbf{y = -\frac 12|x|}[/tex]

Hence, the equation of the graph is [tex]\mathbf{y = -\frac 12|x|}[/tex]

Additional comment

The expression in the second question makes sense for all numbers, real or complex. The value of |x| is never negative, so the value under the radical is always positive.

Answer:

the desired equation is y = (-1/3)x + 6

Step-by-step explanation:

Let the given line be A:  y=3x+2

The slope of line A is m = 3.

The slope of any line B which is perpendicular to line A is the negative reciprocal of the slope of A:  m = -(1/3).

The particular perpendicular line that passes through (3, 5) is then

5 = (-1/3)(3) + b, which simplifies to 5 = -1 + b, or b = 6.

Thus, the desired equation is y = (-1/3)x + 6

Answer:

"O c. 17.156"

Step-by-step explanation:

    A is not a rational number because it cannot be written as a fraction [with two integers] or an integer (the square root of 15 is equal too 3.87298334...)

   B is not a rational number because it also goes on forever, just like A.

    C is a rational number because it does not go on forever.

    D is like A and B, it goes on forever.

thanks for extraaaaaa points

around 19 minutes ^^

(18.85 minutes)

Mary can allocate to each chore around 18.85 minutes.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that Mary has 2 1/5 hours before she needs to meet her friend. She needs to take care of 7 chores before then.

Hence, we get

2 and 1/5 hours = 132 minutes (120 + 12)

thus, Mary will have 132/7 = 18.85714285714286 minutes for each chore.

Or around 18.85 minutes for each chore

Therefore, she can allocate to each chore around 18.85 minutes.

Answer:

y=1/2(x-6)-2

Step-by-step explanation:

y=m(x-h)+k

y=1/2(x-6)-2

Answer:

[tex]y=\frac{1}{2} x-5.[/tex]

Step-by-step explanation:

1) the form of the required line in slope-interception form is:

y=s*x+i, where s [slope] and i [intercept] are numbers;

2) according to the condition s=1/2, it means the required equation can be written as:

y=1/2x+i;

3) in order to calculate the value of 'i', it is needed to substitute (6;-2) into the written required equation:

-2=1/2 *6+i; ⇒ i=-5;

4) finally, if s=1/2 and i=-5, then the required equation is:

y=1/2 *x-5.

P.S. the suggested way is not the shortest one.

Step-by-step explanation:

1.

10x + 8 = 3(x – 2)

10x + 8 = 3x - 6

10x - 3x = -8 -6

7x = -14

x = -14/7

x = -2

2.

10x + 8 = 3x

10x - 3x = -8

7x = - 8

x = -8/7
