m = (y1 - y2) / (x1 - x2)

m = zero slope

(I counted the rest of them)

slope between 2 points (x_1,y_1) and (x_2,y_2) is

slope=\frac{y_2-y_1}{x_2-x_1}


so

given the points (4,\frac{-3}{5}) and (-4,\frac{-1}{3})

(x,y)

x_1=4

y_1=\frac{-3}{5}

x_2=-4

y_2=\frac{-1}{3}

so the slope is

slope=\frac{\frac{-1}{3}-\frac{-3}{5}}{-4-4}

note: -1/3-(-3/5)=-1/3+3/5=-5/15+9/15=4/15, and (a/b)/c=a/(bc)

slope=\frac{\frac{4}{15}}{-8}

slope=\frac{4}{(15)(-8)}

slope=\frac{4}{-120}

slope=\frac{-1}{30}


the slope is -1/30

Will someone please help me with this because I don't understand and I don't want to fail my class.
Marrrta [24]

Answer:

4y + 1 = 4 - 5y

First option

Step-by-step explanation:

x - 4y - 1 =0; add both sides by + 4y + 1

x - 4y - 1 + 4y + 1 = 0 +  4y + 1

Simplifying

x = 4y + 1

x + 5y - 4 = 0; Add (-5y + 4) to both sides

x + 5y - 4 -5y + 4 = 0 -5y + 4

Simplying

x = -5y +4

x = 4 - 5y

Now you have both equations

x = 4y + 1

x= 4 - 5y

Now you can use the comparison method

4y + 1 = 4 - 5y

A section in a stained glass window is shaped like a trapezoid. The top base is 2 centimeters and the bottom base is 4.5 centime
Elza [17]

Answer:

2.8 cm

Step-by-step explanation:

The area of a trapezoid is calculated using the formula:

A=\frac{(B+b)h}{2}

where

B is the length of the major base

b is the length of the minor base

h is the height of the trapezoid

In this problem, the glass window has the shape of a trapezoid. We know that:

B = 2 cm is the length of the top base

b = 4.5 cm is the length of the bottom base

A=9.1 cm^2 is the area of the trapezoid

Solving for h, we can find the height of the stained glass window:

h=\frac{2A}{B+b}=\frac{2(9.1)}{2+4.5}=2.8 cm
