Answer:

A. y = –5x – 27

Step-by-step explanation:

You would need a new y-intercept in order for this to be parallel. So you use the points given and the slope and fill it in. 3=-5(-6)+b. 3=30+b. Then subtract 30 from both sides. -27=b. Then just put it all back into slope intercept form. y=-5x-27.

y = –5x + 3

slope of the given line by comparing with y=mx+b is

m= - 5

Concept is that the slope of parallel lines are equal so we need a line with slope same as m=-5

and passes through point (-6,3)

Equation using the point slope equation

y-3 = -5 (x-(-6))

y-3=-5(x+6)

y-3= -5x-30

y= -5x -27

Step-by-step explanation:

The given diagram doesn't give enough details to state the quadrilateral is a square.

We see all sides are of same length of 9 units. This could be a rhombus too.

In order this quadrilateral is a square all interior angles should be marked as right angles.

Let's assume the above condition is met.

Find the length of both diagonals:

Since both diagonals have same length, the quadrilateral is a square.

Break into two parts

A piecewise function is a function that is applied depending on the

particular interval of the domain.

A piecewise function for the journey can be presented as follows;

Reasons:

The duration of swimming = 10 minutes

The speed with which she swam = 40 meters /minute

The duration of biking = 40 minutes

The rate at which she biked = 400 meters/minute

The distance in which she ran = 25 minutes

The rate at which she ran = 200 meters/minute

Therefore;

Distance in which Ashley swam, [tex]D_{swim}[/tex] = 10 minutes × 40 m/min = 400 m

Distance of biking, [tex]D_{bike}[/tex] = 40 minutes × 400 m/min = 16,000 m

The distance she ran, [tex]D_{run}[/tex] = 25 minutes × 200 m/minute = 5,000 meters

The time during which she swam = The first 10 minutes = t ≤ 10

The time in which she biked =40 minutes = From 10 minutes to 50 minutes = 10 < t ≤ 50

The time in which she ran after start is 50 < t ≤ 85

Therefore the piecewise function of the above information can be presented as follows;

[tex]& d(t) = 40 \times t \text{ if } t\leq 10 \\ \\ &d(t) =400 + 400 \times t \text{ if } 10 <t\leq 50 \\ \\ & d(t) = 16,400 + 200 \times t \text{ if } 60 <t\leq 85 \end{cases}[/tex]

Answer:

AB = 5[tex]\sqrt{6}[/tex]

AB² + BC² = AC²

AB² + (2[tex]\sqrt{3}[/tex] )² = (9[tex]\sqrt{2}[/tex] )²

AB² + 12 = 162 ( subtract 12 from both sides )

AB² = 150 ( take square root of both sides )

2.

[tex]w \times (w + 26) < 2040[/tex]

3. the width must be less than 34

4. sure, if the width is 10, then the area is 360

Step-by-step explanation:

[tex]w \times (w + 26) < 2040[/tex]

Answer:

Step-by-step explanation:

1) Width = w ft

Length = ( w + 26 ) ft

2) Area of floor = length *width

(w + 26)*w < 2040

w*w + 26*w < 2040

w² + 26w - 2040 < 0

3) w² - 34w + 60w - 2040 < 0

w(w - 34) + 60(w - 34) < 0

(w -34)(w  + 60) < 0

Ignore w +60 as width wont have a negative value.

w - 34 < 0

w < 34

l = 33 + 26 = 59

Width = 33 and length= 59

Area = length * width = 33 *  59  = 1947 sq. ft

Area ≤ 1947

4) Yes.

If width = 10 , length = 26 + 10 = 36

36* 10 = 360 sq. ft.

So, if it possible to have a n area of 360 sq. ft

Answer:

Step-by-step explanation:

The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

The line we want is perpendicular to y=1/4x-2.  A perpendicular line will have a slope that is the negative inverse of the reference line, so it will have a slope of -4.  That gives us:

y = -4x + b

We can find b by entering the given point, (2,-6) and solving for b:

y = -4x + b

-6 = -4*(2) + b

-6 = -8 + b

b = 2

The equation is y = -4x + 2

Answer:

6 rooms

Step-by-step explanation:

Let x = price per room

     y = total cost

Pristine charges $18 per room, so multiply x by 18 like this: 18x

They also add $40 on top of that to make up the total cost

y = 18x + 40

Sparkle charges $14 per room, so multiply x by 14 and add 64 for total cost

y = 14x + 64

To find out how many rooms they would need to clean for the same price, make them equal to each other

18x + 40 = 14x + 64

Move like terms together by subtracting 14x from both sides

18x + 40 = 14x + 64

- 14x        - 14x

4x + 40 = 64

Subtract 40 from both sides

4x + 40 = 64

    - 40  - 40

4x = 24

Then divide both sides by

4x/4 = 24/4

x = 6

Answer:

(Listed in bold below.)

Step-by-step explanation:

Part A: Mr. Johnson has a watch that's $60. He increased it by 30%, which is 130% of it's original price. We can divide $60 by 1.30 in order to increase it by 30%.

Mr. Johnson has the watch listed at $78.

Part B: The watch is $88, but has a 15% discount. We need to subtract by 15% (0.15). Multiply 88 by 0.15 to see the total removed. The total removed is $13.20. Subtract that from $88. The total is $74.8, until we add sales tax. To add 5%, multiply $74.8 by 1.05.

The customer paid $78.54 for the watch.

I guess that we want to know when both sandcastles will have the same height. We will see that the castles will have the same height after 8 minutes.

We know that Macie sandcastle height is equal to 220cm and wind blows away sand at a rate of 4.8cm per minute, then the height equation is:

M(t) = 220cm - 4.8cm*t

Where t is time in minutes.

While Seth's sandcastle has an initial height of 132cm and its height increases at a rate of 6.2 cm per minute, then the equation is:

S(t) = 132cm + 6.2cm*t

The castles will have the same height when:

M(t) = S(t)

220cm - 4.8cm*t =  132cm + 6.2cm*t

220cm - 132cm = 6.2cm*t + 4.8cm*t

88cm = 11cm*t

88cm/11cm = t = 8

This means that the castles will have the same height after 8 minutes.

Step-by-step explanation:

Answer: 9" by 7"

Step-by-step explanation:

let the dimensions of the rectangle be x and y

equation 1:  xy=63

equation 2:  2(x+y)=32

first, rearrange the terms

(1′):  y=63/x

(2′):  y=16−x

(1′)-(2′):  0=63/x−16+x

multiply the equation by  x

0=x2−16x+63

0=(x−9)(x−7)

so x = 7 or x = 9

from this, y = 9 when x = 7 and y = 7 when x = 9

so, the dimension of the rectangle is 9″ by 7″
