What is the slope of the line that contains the points (-2,6) and (6,-3)?
m = -9/8 (slope)
This means 9 down, and 8 right.
_________________________
To calculate the slope, just use this formula:
[tex] m \: = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
y2 or x2 can also be thought of as just y and x. This is because only a slope, and one point is needed to solve for another point that fits on the line.
Given point 1 : (-2,6), and point 2 : (6,-3).
We can find slope by: point 2y - point 1y/ point 2x - point 1x =
(-3-6)/(6-(-2)) = (-9)/(8) = -9/8

Answer:
x = 20
Step-by-step
Because the two angles are o the same line ( line t) we know that x+160 will equal 180 degrees, so to solve
180-160= 20
7.) The width of a vegetable garden is times its length. If the length of the garden is 73
feet, what is the width in simplest form?
Answer:
So, the length (L) = 7 3/4 ft = 31/4 (as an improper fraction)
the width (W) = (1/3)xL
So the width = 1/3 x (31/4) =
31/12 = 2 7/12 feet
Step-by-step explanation:
its up there

=====================================================
Explanation:
C is the midpoint of AB. This means AC is half as long as AB
Put another way, AB is twice as long as AC
AB = 2*AC
AB = 2*( AC )
32 = 2*( x/2 + 10 ) .... substitution
32 = 2*(x/2) + 2*10 ... distribute
32 = x + 20
x+20 = 32
x = 32-20 .... subtract 20 from both sides
x = 12
---------
If x = 12, then
AC = x/2 + 10
AC = 12/2 + 10
AC = 6+10
AC = 16
which is half of AB = 32, so it confirms our answer.

What is the supplement of an angle that
measures 21 degrees?
Answer:
159°
Step-by-step explanation:
Supplements equal a total of 180°. The expression for these types of problems would be
180-x
In this case, x would be 21. Plug it in to our expression.

What is angle KNL
Enter your answer in the box
[]
Answer:
20
Step-by-step explanation:
So in case you did not know, MNJ and KNL have the same angle measure, so to find x you would just set each of the eqautions equal to each other. distribute the 3 to (x + 14) and get 5x+ 2 = 3x + 42. subtract 2 from one side and do the same on the other side. this would leave your eqaution looking like this: 5x-40= 3x, next subtract 5x from both sides and you will get -2x=-40, then vide by -2 and x will equal 20

3(5x+1)-3x=2-3(3x+1)
Answer:
x = − 4 \21
Step-by-step explanation:
Answer:
x= [tex]-\frac{4}{21}[/tex]
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
(3)5x+(3)1-3x=2+(-3)3x+(-3)1
Step 2- Multiply.
15x+3-3x= 2-9x-3
Step 3- Add common variables.
(15x-3x)+3=(2-3)-9x
12x+3=-1-9x
Step 4- Add 9x to both sides.
12x+3= -1-9x
+9x +9x
21x+3= -1
Step 5- Subtract 3 to both sides.
21x+3= -1
-3 -3
21x= -4
Step 6- Divide both sides by 21.
21x= -4
21 21
x= [tex]-\frac{4}{21}[/tex]
