Answer:

[tex]y = -\frac{8}{x}[/tex]

Step-by-step explanation:

Given

Inverse Variation:

[tex]Points: \{(-1, 8), (4, -2), (-2, 4)\}[/tex]

Required

Determine the equation of the relation

An inverse relation is represented as:

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

Where k = constant of variation

Make k the subject:

[tex]k = xy[/tex]

When x = -1, y = 8

So, we have:

[tex]k = -1 * 8[/tex]

[tex]k = -8[/tex]

When x = 4, y = -2

[tex]k = 4 * -2[/tex]

[tex]k = -8[/tex]

When x = -2, y = 4

[tex]k= -2 * 4[/tex]

[tex]k = -8[/tex]

From above calculations, we've established that:

[tex]k = -8[/tex]

Substitute -8 for k in [tex]y = \frac{k}{x}[/tex]

[tex]y = \frac{-8}{x}[/tex]

[tex]y = -\frac{8}{x}[/tex]

Hence, the equation is:

[tex]y = -\frac{8}{x}[/tex]

Answer:

180 pages

Step-by-step explanation:

Let

x = total number of pages

Monday + Tuesday + Wednesday

2/15x + 1/3x + 2/9x

= (6x+15x+10x)/45

= 31/45x

Thursday

x - 31/45x

= (45x-31x)/45

= 14/45x

3/4 of 14/45x

= 3/4 * 14/45x

= 42/180x

Total pages read = 31/45x + 42/180x

= (124x+42x)/180

= 166/180x

If he still has 14 pages left to read on Friday

Total read from Monday to Thursday + Friday

x = 166/180x + 14

x - 166/180x = 14

(180x-166x)/180 = 14

14/180x = 14

x = 14 ÷ 14/180

x = 14 × 180/14

x = 180 pages

Answer:

y=-2/3x-7

Step-by-step explanation:

parallels have the same slope just different y ints

to find what the y int is i just graphed the point (6,-11) to a calculator and made an equation with a slope of -2/3 and plugged in different y ints to get this

Answer:

i think the answer is area = 1695.47 ft squared

Step-by-step explanation:

just do 45.7 x 37.1 since you’re finding area of a SQUARE which has all equal sides.

Answer:

It would be B

Step-by-step explanation:

8/3=2.66666666667

meaning x=8/3

Answer:

1,420 milligrams

Step-by-step explanation:

We know there are 100 centigrams in 1 gram, and there are 10 milligrams in a centigrams. That would mean there are 1,000 milligrams in 1 gram (100 * 10 = 1000).

As a result, all you need to do is multiply 1.42 by 1000 to get the amount of milligrams.

1.42 * 1000

Alternatively, to make 1.42 a whole number first, multiply by 100, then add a zero. (That's the other 10!)

(1.42 * 100) * 10

142 * 10

There are 1,420 milligrams in 1.42 grams.

Answer:

Option (4)

Step-by-step explanation:

Let the input output values of the table are represented by the equation,

y = mx + b

Here m = rate

b = y-intercept

Since, at x = 0, y = -1 [Point given in the table]

y-intercept 'b' = 0

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

Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points given in the table.

If the points are (-2, -5) and (-1, -3),

Substitute the values in the formula,

Rate = [tex]\frac{(-5)-(-3)}{(-2)-(-1)}[/tex]

        = [tex]\frac{-5+3}{-2+1}[/tex]

        = 2

Therefore, Option (4) will be the answer.

Answer:

1)y=-3+5x

2)y=5/2-1/2x

Step-by-step explanation:

for both equations

1) get your y by it self (subtract -5x and your new equation is now -y=-5x+3)

2)(reminder y can't be negative if it is negative) then you divide by -1 of both sides

3) your equation should now be y=5x-3

Answer:

19/1200

Step-by-step explanation:

Answer:

a = 2

b = 4

Step-by-step explanation:

In parallelogram opposite sides are equal.

4a +  b  = 2a + 8

4a - 2a + b = 8

      2a + b = 8 -----------------(I)

             b = 8 - 2a

11b - 10a = 6b

11b - 6b -10a = 0

5b - 10a = 0 ---------(II)

Substitute b = 8 - 2a  in equation (II)

5*(8-2a) - 10a = 0

5*8 - 2a * 5 - 10a = 0

     40 - 10a - 10a = 0

      40 - 20a       = 0

                  -20a = - 40

                       a = -40/-20

                      a = 2

Plugin a = 2 in equation (I)

2*2 + b = 8

4 + b   = 8

       b = 8 -4

      b = 4

Answer:

[tex]\frac{6x-4}{x}[/tex]

Step-by-step explanation:

(5 x 6)(3x - 2) = 15xn

30(3x - 2) = 15xn

[tex]\frac{2}{1}[/tex] * (3x - 2) = ([tex]\frac{1}{2}[/tex]xn) * [tex]\frac{2}{1}[/tex]

6x - 4 = xn

n = [tex]\frac{6x-4}{x}[/tex]

You can't cross the 'x' out of the numerator or denominator because of the - 4 in the numerator.

Answer:

a

Step-by-step explanation:

the answer is a because every week it shows (shows on the graph) that he is earning 6 dollars.

Answer:

A

Step-by-step explanation:

The formula for slope is [ y2-y1/x2-x1 ] and we can use the points (0, 0) and (5, 30) to solve.

30-0/5-0

30/5

6/1

6

Now that we know what the slope is, we can eliminate C and D.

This means that he saves around $6 per week. With this being said, we can eliminate B as well.

Best of Luck!

Answer:

A. c(r)=$19.5 if r < 2

c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2

B. $29.78

Step-by-step explanation:

A. Based on the information given if we are to express the cost of the resumes which is c(r) algebraically as a piecewise function what we would have will be:

c(r)=$19.5 when r represent an INTERGER and is less than 2

c(r)=$19.5+(r-2) ($9) (1+0.045)

c(r)=$19.5+(r-2) ($9) (1.045) when r represent an INTERGER and is greater than 2

Therefore to express the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2

c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2

B. Calculation for How much will 300 copies cost, including a sales tax of 4 1/2%

Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)

Cost of 300 copies=$28.5+$28.5(0.045)

Cost of 300 copies=$28.50+$1.28

Cost of 300 copies=$29.78

Therefore How much will 300 copies cost, including a sales tax of 4 1/2% will be $29.78

Answer:

$11.90

Step-by-step explanation:

first you change the percent to a decimal by moving the decimal two places and then multiply.

you multiply .85 and 14.00= 11.90

Answer:

$11.9

Step-by-step explanation:

The regular cost of the CD = $14:00

The discount she gets = 15%

So, 15% of $14 = 2.1

= $14 - $2.1 = $11.9

Another method:

Or u can take 85% of $14 and u will get the immediately

85% of $14 = $11.9

Answer:

B. 600 ft

Step-by-step explanation:

The formula for the Perimeter of a right triangle = Side a + Side b + Side c

The perimeter of a right triangle is 60 feet

If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle?

Hence, the perimeter of the new right triangle = 10 × 60ft

= 600ft

Option B is the correct Option.

Answer:

600
