Which of the following is an arithmetic sequence?
A. -4,-2, 0, 2, ...
B. -8, -4,-2, -1, ...
C.-4, -3, -1, 2, ...
D. -4, 0, -4, 0, ...
is equal to zero if. a) a, b, c are in arithmetic progression ... progression. d) α is a root of the equation ax2 + bx + c = 0.Missing: 4,
Explanation:
This is because we are adding the same thing to each term to get the next term. That is the common difference d = 2
second term = (first term)+d = -4+2 = -2third term = (second term)+d = -2+2 = 0fourth term = (third term)+d = 0+2 = 2Solve for x: 1.5x - 8 = 7
PLS ANSWER
Answer:
x = 10Step-by-step explanation:
1.5x - 8 = 7
=> 1.5x = 7 + 8
=> 1.5x = 15
[tex] = > \frac{15x}{10} = 15[/tex]
[tex] = > x = 15 \times \frac{10}{15} [/tex]
=> x = 10 (Ans)
Answer:
x=10
Step-by-step explanation:
Simplifying
1.5x + -8 = 7
Reorder the terms:
-8 + 1.5x = 7
Solving
-8 + 1.5x = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '8' to each side of the equation.
-8 + 8 + 1.5x = 7 + 8
Combine like terms: -8 + 8 = 0
0 + 1.5x = 7 + 8
1.5x = 7 + 8
Combine like terms: 7 + 8 = 15
1.5x = 15
Divide each side by '1.5'.
x = 10
Simplifying
x = 10

Hope I helped, have a nice day :)
find the outputs.. please help
Answer:
see below
Step-by-step explanation:
The steps are +2 then *4 then -8 then ÷2
Input is 5
5 +2 =7 *4 = 28-8 = 20 ÷2 = 10 Output is 10
Input is 9
9 +2 =11 *4 = 44-8 = 36 ÷2 = 18 Output is 18
Input is 14
14 +2 =16 *4 = 64-8 = 56 ÷2 = 28 Output is 28
Input is 18
18 +2 =20 *4 = 80-8 = 72 ÷2 = 36 Output is 36
Input is 23
23 +2 =25 *4 = 100-8 = 92 ÷2 = 46 Output is 46
Input is 7.5
7.5 +2 =9.5 *4 = 38-8 = 30 ÷2 = 20 Output is 20
Input is 11.54
11.54 +2 =13.54 *4 = 54.16-8 = 46.16 ÷2 = 23.08 Output is 23.08
Answer:
Output:
5 + 2 x 4 - 8 ÷ 2 = 9
9 + 2 x 4 - 8 ÷ 2 = 13
14 + 2 x 4 - 8 ÷ 2 = 18
18 + 2 x 4 - 8 ÷ 2 = 22
23 + 2 x 4 - 8 ÷ 2 = 27
7.5 + 2 x 4 - 8 ÷ 2 = 11.5
11.54 + 2 x 4 - 8 ÷ 2 = 14.54

The triangles at the right are similar. What is the ratio (larger to smaller ) of the perimeters ?
Answer:
The perimeters are in the same ratio as the corresponding sides.
Step-by-step explanation:
There is no diagram given in your question, so imagine an example in which the ratio of two corresponding sides is, say, 7:4 (or 7/4). Then the perimeters are in the same ratio, 7:4.
Note: The areas are in the ratio which is the square of the ratio of sides, so 49:16 in the example.

Write the following equation in the general form Ax + By + C = 0.
2x + y = 6
Answer:
2x + y - 6 = 0
Step-by-step explanation:
Here, C represents a constant value. So the only thing we really need to do here is subtract 6 because 6 is a constant value and because we would get 0 on the right side. I know this isn't a very good explanation so feel free to ask me any questions that you may have.
what's the value of x 2x-7=13 3x+4=25
Answer:
2x-7=13 (x=10) 3x+4=25 (x=7)
Step-by-step explanation:
1. 2x-7=13
Add 7 to both sides, then simplify. Then, divide both sides by two. Simplify furthermore to get the answer.
2x-7+7=2x 13+7=20.....2x=20 2x/2=x 20/2=10.....x=10

Which equation gives the sum of infinity sigma 6( 1/3) HURRY PLEASE
Answer:
3rd option
Step-by-step explanation:
The sum to infinity of a geometric sequence is
S = [tex]\frac{a}{1-r}[/tex]
where a is the first term and r the common ratio
The expression inside the summation is
6 [tex](\frac{1}{3}) ^{n-1}[/tex]
which is in the form of the nth term of a geometric sequence
with a = 6 and r = [tex]\frac{1}{3}[/tex] , then
S = [tex]\frac{6}{1-\frac{1}{3} }[/tex] ← expression required
= [tex]\frac{6}{\frac{2}{3} }[/tex]

1) In which quadrant do the following point lie?
1) (-5,4), (ii)(4,-2) (iii) 7,2) (iv) (-3,-7)
Answer:
Step-by-step explanation:
(-5,4)=since x coordinate is negative and y coordinate is positive it lies on 2 nd quadrant.
(4,-2)=x coordinate is positive and y coordinate is negative so it lies on 4 th quadrant
(7,2)=both x coordinate and y coordinate are positive so they lie in 1 st quadrant.
(-3,-7) =both x and y coordinate are negative so they lie on 3 nd quadrant
The height, h metres, of a springboard diver above the surface of the water t seconds after she leaves the board is given by h=-5t-12+7. Find the maximum height reached by the diver? How long does it take for the diver to reach maximum height? Find the height of the diving board?
Answer:
[tex]h_{max} = 14.2m[/tex]
[tex]t = 1.2[/tex]
The height of the diver is 7m
Step-by-step explanation:
Given
[tex]h(t) =-5t^2 + 12t + 7[/tex]
Solving (a): The maximum height reached
First, we calculate the time to reach the maximum height using:
[tex]t = - \frac{b}{2a}[/tex] --- maximum of a function
Where
[tex]a = -5; b = 12; c = 7[/tex]
So, we have:
[tex]t = -\frac{12}{-2 * 5}[/tex]
[tex]t = \frac{12}{10}[/tex]
[tex]t = 1.2[/tex]
So, the maximum height is:
[tex]h(t) =-5t^2 + 12t + 7[/tex]
[tex]h(1.2)=-5 * 1.2^2 + 12 * 1.2 + 7[/tex]
[tex]h(1.2)=14.2[/tex]
Hence:
[tex]h_{max} = 14.2m[/tex]
Solving (b): Time to reach maximum height
This has been calculated in (a)
[tex]t = 1.2[/tex]
Solving (c): Height of the board.
This can be calculated by setting [tex]t =0[/tex] --- i.e. the height of the diver before diving
So, we have:
[tex]h(t) =-5t^2 + 12t + 7[/tex]
[tex]h(0) = -5 * 0^2 + 12 * 0 + 7[/tex]
[tex]h(0) = 7[/tex]

Solve the equation 18y – 17 = 7 for y.
Answer:
24/18 OR 4/3 OR 1.3333...
Step-by-step explanation:
18y - 17 = 7
Add 17 from both sides.
18y = 24
Divide 18 from both sides to leave the y alone.
y = 24/18 ≈ 1.3333...

A printing company is enlarging the image on a postcard to make a greeting card. The enlargement of the postcard’s rectangular image is done using a scale factor of 125%. Be sure to show all other related math work used to answer the following questions.
(a)Represent a scale factor of 125% as a fraction and decimal.
(b)The postcard’s dimensions are 7 inches by 5 inches. What are the dimensions of the greeting card?
(c)If the printing company makes a poster by enlarging the postcard image, and the poster’s dimensions are 28 inches by 20 inches, represent the scale factor as a percent.
(d)Write an equation, in terms of the scale factor, that shows the relationship between the areas of the
postcard and poster. Explain your equation.
(e)Suppose the printing company wanted to start with the greeting card’s image and reduce it to create the postcard’s image. What scale factor would they use? Represent this scale factor as a percent.
(f). In math class, students had to create a scale drawing that was smaller than the postcard image. Azra
used a scale factor of 60% to create the smaller image. She stated the dimensions of her smaller image as 4 1/6 inches by 3 inches. Azra’s math teacher did not give her full credit for her answer. Why? Explain Azra’s error, and write the answer correctly

Helen rented a kayak at the lake. There is a charge of $10 as an initial fee and then $2 an hour for every hour that she uses the kayak. If the total charge is $22 , how many hours did she kayak?
Answer:
She kayaked for 6 hours.
Step-by-step explanation:
If $10 is the initial fee, subtract $22 - $10 = $12.
If it charges $2 per hour, divide $12 by $2 which equals 6 hours.
Answer:
6 hours
Step-by-step explanation:
Cost = fee + charge per hour * number of hours
22 = 10 +2h
Subtract 10 from each side
22-10 = 10+2h-10
12 = 2h
Divide
12/2 = 2h/2
6 = h
