Answer:

(x,y)=(3,14)

Step-by-step explanation:

y-6x=-4 , y=-4+6x

y-2x=8, y=8+2x

(y=)-4+6x=8+2x

6x-2x=8+4

4x=12

x=12/4

x=3, then

y=-4+6*3=-4+18=14

(x,y)=(3,14)

Find the midpoint of a and b when a has coordinates (-5,3) and b has coordinates (3,-1)

azamat

To find the x coordinate of the midpoint, add the x coordinates and divide by 2
(-5+3)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
(3+-1)/2 = 2/2 = 1
(-1,1)

Answer:

y=3×-11

Step-by-step explanation:

y=m+c

m=7-1÷6-4

m=6÷2

m=3

y=3+c

7=3(6)+c

7-18=c

-11=c

y=3×-11

I WILL MARK BRAINIEST<br> I got one correct there should be about one more that’s also right

Lesechka [4]

So essentially an adjacent angle is when two angles have a common side and a common vertex.

So knowing that we can determine from the picture all the adjacent angles:

D) <2 and <3 are adjacent angles

E) <1 and <3 are adjacent angles

F) <1 and <5 are adjacent angles

I hope this helps.

Helen's house is located on a rectangular lot that is1 1-8 miles by 9/10 mile.Estimate the distance around the lot

klemol [59]

Answer: The distance around the lot is given by

$4\frac{1}{20}\ miles$

Step-by-step explanation:

Since we have given that

Length of rectangular lot is given by

$1\frac{1}{8}\\\\=\frac{9}{8}\ miles$

Width of rectangular lot is given by

$\frac{9}{10}\ mile$

We need to find the distance around the lot.

As we know the formula for "Perimeter of rectangle":

$Perimeter=2(Length+Width)\\\\Perimeter=2(\frac{9}{8}+\frac{9}{10})\\\\Perimeter=2(\frac{45+36}{40})\\\\Perimeter=2\times \frac{81}{40}\\\\Perimeter=\frac{81}{20}\\\\Perimeter=4\frac{1}{20}\ miles$

Hence, the distance around the lot is given by

$4\frac{1}{20}\ miles$
