Answer:
an = 6n - 18
Step-by-step explanation:
a3 = 0, a4 = 6, a5 = 12, a6 = 18, a7 = 24
a3 = a + 2d
a4 = a + 3d
a + 2d = 0 (1)
a + 3d = 6 (2)
Subtract (1) from (2) to eliminate a
3d - 2d = 6 - 0
d = 6
Substitute d = 6 into (1)
a + 2d = 0 (1)
a + 2(6) = 0
a + 12 = 0
a = -12
nth term,an = a + (n - 1)d
= -12 + (n - 1) 6
= -12 + 6n - 6
= 6n - 18
an = 6n - 18

What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x - 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear.
Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, Two linear equations in two variables 'x' and 'y',
9x - 4y = 19 and 4x + 4y = 20.
Now, Adding these two equations we have,
13x = 39.
x = 3 and hence y = 2.

Zanara has 7 heart stickers and 24 cupid stickers. She wants to divide into 3 equal groups to give to her friends. How many stickers will each group have?
Answers
Answer: Each group will have 10 stickers.
Step-by-step explanation:
Given: Number of heart stickers = 7
Number of cupid stickers = 24
Total stickers = 7+24 = 31
If she divides them into 3 groups, then each group will have [tex]31 \div3[/tex] stickers
= 10 stickers ( 1 left) [ when we divide 31 by 3 , we get 10 as quotient and 1 as remiander ]
Hence, each group will get 10 stickers.
A telephone pole is 54 feet tall. A guy wire runs 79 feet, from point A at the top of the telephone pole, to the ground at point B. The base of the telephone pole is at point C. Triangle ABC is a right triangle.

ft
Answers
Answer:
57.7 ft
Step-by-step explanation:

The distance that the base of the telephone pole to point B where the guy wire is secured to the ground is 57.7 feet
What is Pythagoras Theorem?Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
Given that triangle ABC is a right triangle.
Point A is the top of the telephone pole.
Point B is the point on the ground.
Point C is the base of the telephone pole.
Given,
AB = 79 feet
AC is the height of the telephone pole = 54 feet
Angle C is a right angle.
Using Pythagoras theorem,
(AB)² = (AC)² + (BC)²
79² = 54² + (BC)²
(BC)² = 79² - 54²
(BC)² = 3325
BC = √3325 = 57.66 ≈ 57.7 feet
Hence the length of the base of the pole form the ground where the wire is secured is approximately 57.7 feet.

What is the solution to -2|2.2x - 3.3| = -6.6?
O x=-3
O x=3
O x=-3 or x = 0
O x = 0 or x = 3
Answers
The solution to the equation, -2|2.2x - 3.3| = -6.6, which contain an absolute value, is: D. x = 0 or x = 3.
What is the Solution of an Equation with an Absolute Value?To determine the solution, we have to isolate the value and find its value.
Given the equation, -2|2.2x - 3.3| = -6.6:
-2|2.2x - 3.3| = -6.6
2.2x + 3.3 = 3.3
2.2x = 3.3 - 3.3
2.2x = 0
x = 0/2.2
x = 0
Or
2.2x - 3.3 = 3.3
2.2x = 3.3 + 3.3
2.2x = 6.6
x = 6.6/2.2
x = 3
The solution is: D. x = 0 or x = 3
