Answer:
aₙ = - 30n + 9
Step-by-step explanation:
You can tell this is an arithmetic sequence, as there is a difference of 30 between each value. Therefore the equation we will use here is aₙ = a₁ + (n - 1)d.
aₙ = a₁ + (n - 1)d
= - 21 + (n - 1) * - 30
= - 21 - 30n + 30
= - 30n + 9
Your solution would be option d. aₙ = - 30n + 9

(6,11) and (5,9) on a line in standard form
Answers
Answer:
2x - y = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6, 11) and (x₂, y₂ ) = (5, 9)
m = [tex]\frac{9-11}{5-6}[/tex] = [tex]\frac{-2}{-1}[/tex] = 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (5, 9) , then
9 = 10 + c ⇒ c = 9 - 10 = - 1
y = 2x - 1 ← in slope- intercept form
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
From y = 2x - 1 ( subtract y and add 1 to both sides )
2x - y = 1 ← equation in standard form

Answers
Answer:
B)Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90 clockwise
Step-by-step explanation:
This is because, to locate a point rotated by 90° from point A, we first draw a circle with the origin as its center and a radius of the origin and point A. We then locate a point on the line that is 90° clockwise from point A. For a 90° clockwise rotation, for a given pair of coordinates, (x,y), the resulting pair of coordinates is (y,-x). So, for the coordinates (1,4), the resulting coordinates we are looking for is (4, -1), which is the point rotated 90° clockwise from point A. The point is thus (4,-1).

Answer:See below
Step-by-step explanation:
These angles are equal. All that needs to be done is setting the equations as equal and solving for the variables. Once the variables are found, input them back into the equation to find the angles. Once the variables are put into both equations, the result should be equal.
Answer:
13) 94°
14) 105°
Step-by-step explanation:
13) For this equation, the angles are vertical angles. This means that they equal each other. So the equation would be: 14x-4= 12x+10.
Step 1- Subtract 12x to both sides.
14x-4= 12x+10
-12x -12x
Step 2- Add 4 to both sides.
2x-4= 10
+4 +4
Step 3- Divide both sides by 2.
2x= 14
2 2
x= 7
Now that you know the value of the variable, insert this into the equations.
14(7)-4= 98-4= 94°
12(7)+10= 84+10= 94°
14) For this equation, the angles are alternate exterior angles. This also means that they equal each other. So the equation would be: 16x-7= 15x.
Step 1- Add 7 to both sides.
16x-7= 15x
+7 +7
Step 2- Subtract 15x to both sides.
16x= 15x+7
-15x -15x
This leaves you with: x= 7.
Now, insert the value of the variable into the equations.
16(7)-7= 112-7= 105°
15(7)= 105°

Answer:
x= 29
Step-by-step explanation:
These angles equal 180° since they are corresponding angles.
So, the equation would be: (2x-10)+(4x+16)= 180.
Step 1- Add common variables.
(2x+4x)+(16-10)= 180
6x+6= 180
Step 2- Subtract 6 to both sides.
6x+6= 180
-6 -6
6x= 174
Step 3- Divide both sides by 6.
6x= 174
6 6
x= 29
Answer:
x=29
Step-by-step explanation: The two angles for are supplementary, so the equation will be equal to 180 degrees. So to find 180 degrees you need to put (2x-10) and (4x+16) on the same side of the equation.
180=(2x-10)+(4x+16) Combine like terms
180=6x+6 Subtract 6 from both sides
174=6x Divide both sides by 6
29=x
Check:
2*29-10
58-10= 48
4*29+16
116+16=132
132+48=180
