A proportional relationship between y and x. When x = 3, y=−4 .

What is the constant of proportionality, k?

Enter your answer as a simplified or improper fraction in the box.

k =

Answer:

y= -1/2x

Step-by-step explanation:

y-y1/x-x1=y2-y1/x2-x1

y-1/x+2=-1/2

2y-2= -x-2

2y= -x-2+2

2y=-x

y=-1x/2„

Answer:

y= -1/2x

Answer:

The required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

Step-by-step explanation:

In this question we need to find the equation of the graph in factored form.

The factored form will be: [tex]f(x)=a(x-r_1)(x-r_2)..[/tex]

where a is y-intercept and r₁, r₂ are x-intercepts

X-intercepts

When y=0, the values of x axis are known as x-intercepts

Y-intercepts

When x=0, the values of y-axis are known as y-intercepts.

Looking at the graph finding x-intercepts

When y=0 x=-2 and 1

So, we have

r₁ = -2

r₂ = 1

Looking at the graph finding y-intercepts

When x=0, y=-4

So, a = -4

Putting values in the formula we will get:

[tex]f(x)=a(x-r_1)(x-r_2)\\f(x)=-4(x-(-2))(x-1)\\f(x)=-4(x+2)(x-1)[/tex]

So, the required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

sunglasses are on sale this week for $17 and they were formally $20.

A= 15%

Answer:

18

Step-by-step explanation:

Solve the separate part of the equation first

6(4) 6(-2) would equal 24-12

Add it back in to get: 10 - 4 + 24 - 12

-4-12 and 10+24 are the like terms so

10+24 = 34 and -4-12 = -16

Equation in the end: 34-16

Simplify that to: 34-16 = 18

Answer: 18

Step-by-step explanation: do ten minus four plus six and get twelve then dont subtract four from two add  and you get 6 add that two gether and get eighteen

Answer:

{y,x} = {7,-1}

Step-by-step explanation:

(-7x) + 3x = 4

- 4x = 4

 4x = - 4

x = - 1

   y = -7x

   x = -1

   y = -7(-1) = 7

Answer:

7

Step-by-step explanation:

12=5+4p+3p ---> subtract the 5 to the other side

12-5=4p+3p ---> combine like terms

7=p

Answer: If you place 10 packages per box, each box will weigh 10(3 lb 4 oz). This is 30 lb 40 oz. For 4 boxes you would have 4(30 lb 40 oz). This is 120 lb 160 oz. To put you answer in the correct form you need to change the 160 oz to pounds and ounces. 16 oz is equal to 1 pound, so divide 160 by 16. The 160 oz is equivalent to 10 lbs. Therefore the total weight of 4 boxes is 120 + 10 which equals 130 lbs.

Answer:

Both groups need more boats

1.) 5x=36

36/5

=7.2 boats

2.) 7.2 but you can't split a boats nor can you decrease the amount of people so 8 boats.

3.)4x=24

24/4

=6 boats

Answer:

m1 =131 degrees

m2=49 degrees

Step-by-step explanation:

Alternate interior angles are always congruent, so they will be equal to each other, so m1=131 degrees.

Straight angles always add up to 180 degrees, so 180-131=49, so m2=49 degrees

Answer:

$98

Step-by-step explanation:

21 × 5 ( since there are 5 friends )

= 105

595 - 105 = 490 (total cost for all 5 of the return flight)

490 ÷ 5 = 98

$ 98 for each person.

First, find the discount by finding 10% of $14.58. To do this, convert 0% into a decimal and multiply by $14.58.

14.58 x 0.1 = 1.458.

Since this a sale price, how much he is getting off, subtract from the total.

14.58 - 1.458 = 13.122.

We still have to find the sales tax. Solving is similar to finding the discount.

13.122 x 0.0825 = 1.082565.

Now, since it is a tax, add to the total.

13.122 + 1.082565 = 14.204565

Round to the nearest hundredth, and you have $14.20.

The sale price with after tax is $14.20.
