2x - 11
-9 + x
equate the equations
2x - 11 = -9 + x
bring like terms to one side
2x - 11 = -9 + x
- x +11 +11 - x
-11 and +11 cancels out
+x and -x cancels out
2x - x = 11 - 9
x = 2
Answer:
The answer is 31
Step-by-step explanation:
221 divided by 6 is 36-5=31
This is correct because if you divide 221 by 6 you get 36 the subtract 5 from 36 and get 31. To check this answer just do 31+5=36 times 6 which is 216 and 221 minus 5 is 216:)
Answer: The answer is either letter A or letter C

By definition, the slope or gradient of a line describes its steepness, incline, or grade.
Where
m — slope
θ — angle of incline
If the 2 Points are Known
Result
Slope (m) =
ΔY
ΔX
=
-1
5
= -0.2
θ =
arctan( ΔY ) + 360°
ΔX
= 348.69006752598°
ΔX = 5 – -5 = 10
ΔY = -3 – -1 = -2
Distance (d) = √ΔX2 + ΔY2 = √104 = 10.198039027186
Equation of the line:
y = -0.2x – 2
or
y =
- 1 x
5
– -2
When x=0, y = -2
When y=0, x = -10

Step-by-step explanation: This is the picture, I graphed it
Center: (0, 0)
Angle: 0 rad
Opacity: 1
Width: 10
Height: 6.8
X + 3/4 > 11/4
X > 8/4
X > 2
So make a rectangle that extends from 2 and above
In inequalities normal athematic are used the only difference is that you flip the operator when dividing over -1 or taking inverse
D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x.
4/8=x/6. Then just cross multiply and solve from there.
