Answer:

(1, -2)

(-8, -2)

Step-by-step explanation:

(1 , -6) and (-8 , -6)

1 - (-8) = 9

we know that the length of the side that we know the vertices is 9

from there we make an equation with the sum of the sides equal to the perimeter

we will have 2 times 9 and 2 times x beacause it is a rectangle

x + x + 9 +9 = 26

2x + 18 = 26

2x = 26 - 18

2x = 8

x = 8/2

x = 4

Now that we know the missing side we just have to add or subtract this value to the coordinate in and of the vertices we have and we will obtain the missing vertices

(1, -6 + 4)

(1, -2)

( -8, -6+4 )

(-8, -2)

Lerok [7]

Answer:

a. 28.8

Step-by-step explanation:

Using the theorem of similarity, the following equation can be generated:

\frac{x}{12} = \frac{25 + 35}{25}

Solve for x

\frac{x}{12} = \frac{60}{25}

Cross multiply

x*25 = 60*12

25x = 720

Divide both sides by 25

x = 28.8

Answer=18%

177/150=1.18

1.18=118%

118%-100%=18%

URGENT HELP What is the equation of the line that passes through the point (-7, -4) and has a
shepuryov [24]

The final equation is:

y=x+3

Further explanation:

The general form of equation of a line in slope-intercept form is:

y=mx+b

Here m is the slope

Given

m=1

(x,y) = (-7,-4)

Putting\ the\ value\ of\ slope\ in\ equation\\y=(1)(x)+b\\y=x+b

To find the value of b, we have to put the point in the equation

-4=-7+b\\-4+7=b\\b=3

The final equation is:

y=x+3

Keywords: Slope-intercept form, equation of line
