Answer:

y=-32+126

Step-by-step explanation:

So the equation you've given me is: y=-32x+1 which is already in slope intercept form.

The slope remains the same so let's look at the y-intercept (b) which is not going to come into solving it.

Plug in the points into the equation to become: -2=-32(4)+b

Solve the equation to get 126=b

Plug it into your new equation: y=-32x+126

An exterior angle equals the sun of the two opposite inside angles:

5x = 120 + x

Subtract 1 x from both sides:

4x = 120

Divide both sides by 4:

X = 30

The answer is D. 30

Answer : The shape of the fence will be a circle

              dimensions of the fence are : radius = 6.5 meters

Step-by-step explanation:

First we calculate the length of the different arms

AB = [tex]\sqrt{(-2+6)^2 + (-3+1)^2}[/tex]

     ≈ 4.47

CD = [tex]\sqrt{(5-3)^2 + (0-4)^2}[/tex]

     ≈ 4.47

Next we calculate the midpoint of these two arms

M1 = [tex]( \frac{-6-2}{2} , \frac{-1-3}{2} )[/tex] = ( -4, -2 )

M2 = [tex]( \frac{3+5}{2} , \frac{0+4}{2} )[/tex]  = ( 4,2 )

hence midpoint of M1,M2 =( M ) = ( 0,0 )

finally considering M calculate the distance between M and car B,D

MB = [tex]\sqrt{(0+2)^2 + (0+3)^2}[/tex]  = 3.60

MD = [tex]\sqrt{(0-5)^2 + (0)^2}[/tex]  = 5

therefore the radius of the fence will be

= 5 + 1.5 = 6.5 meters ( because MD > MB )

b. The store bought the dishwasher for the price they are currently selling it at. They are receiving no profit when it is on sale.

Step-by-step explanation:

give brainliest pls

If 20% is the greatest possible markdown the store can give without losing money, then the price of the dishwasher is $761.60

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that the Sales price = $952

Markdown % = 20%

The Sales price = (100 - 20)% x $952

The Sales price = 80% x $952

The Sales price = $761.60

If 20% is the greatest possible markdown the store can give without losing money, then the price of the dishwasher is $761.60

The correct answer is $30.5 or $31 if rounded

Explanation:

To find the total Rosa spent on the manicure, it is necessary to calculate the money spent on taxes and the money she tipped to the technician. The process is shown below:

Taxes:

$25 represents 100% of the cost and 7% percent represents the total taxes.

1. Write the values using x as the value you want to know

25 = 100

x   = 7

2. Use cross multiplication

x 100 =  175

3. Solve this equation

x = 175 / 100

x = 1.75 (Total price for taxes)

Tip:

Repeat the process but in this case calculate the 15% of $25

25 = 100

x =  15

x 100 = 375

x = 375 / 100

x = 3.75

Total: Finally, add the three values

$25 (cost of the manicure) + $ 1.75 (taxes) + $3.75 (tip) = $30.5 or $31 if rounded

Step-by-step explanation:

The coordinates of the vertices of parallelogram WXYZ are given to be W(0,-1), X(4,0), Y(3,-2) and Z(-1,-3).

So, the perimeter of the parallelogram will be 2(WX + XY) {Since opposite sides of parallelogram are same in length}

Now, length of WX =  units,  To find the units click this link :

Answer:

The degree of the polynomial is even because it is a 4th degree polynomial. 4 is even, so the graph will behave roughly like a quadratic; namely, its graph will either be up on both ends or else be down on both ends.

The y-intercept is the constant term. The constant term is -4 because it is the only number on the y-axis.

y= -2/3x - 4

x= 3/2y + 6

Step-by-step explanation:

2x - 3y = 12 (plus 3y)

2x = 3y +12 (divide by 2)

x = 3/2y + 6

2x - 3y = 12 (minus 2x)

-3y = 2x + 12 (divide by -3)

y = -2/3x - 4
