Answer:
nth term = 7n - 2
Step-by-step explanation:
The first 4 term of the arithmetic sequence is 5, 12 , 19 and 26. The expression in terms of nth term that model this sequence can be express below
The nth term of the arithmetic sequence form can be represented as follows.
nth = a + (n - 1)d
where
a = first term
d = common difference
Therefore,
a = 5
d = 12 - 5 = 7 or 19 - 12 = 7 or 26 - 19 = 7
nth = a + (n - 1)d
nth term = 5 + (n - 1)7
nth term = 5 + 7n - 7
nth term = 7n - 2

On a map of a town, a school is located at (–6, 2) and a movie theater is located at (–6, –15). What is the distance from the school to the theater on the map?
Answer:
13 units
Step-by-step explanation:
Since the x-coordinates are the same, you can simply add the absolute value of the y-coordinates.
|2 + (-15)|
or
|2 - 15|
= 13
Therefore, the distance from the school to theater is 14 units.
Answer:
13 units

At their family's pizzeria, Dave makes 6 pizzas in the first hour it is open and 3 pizzas each hour after that. Lauren makes 11 pizzas in the first hour and 3 pizzas each hour after that. If the pizzeria is open for 6 hours, how many pizzas will they make in all?
Answer:
47 pizzas
Step-by-step explanation:
Dave makes 6 pizzas in the first hour it is open and 3 pizzas each hour after that.
If the number of hours after the first hour is represented as x, then the number of pizzas he makes after x hours is:
6 + 3x
Lauren makes 11 pizzas in the first hour and 3 pizzas each hour after that. Then:
11 + 3x
The pizzeria is open for 6 hours in all, that is, 5 hours after the first hour.
This means that:
x = 5
The total amount of pizzas that Dave and Lauren make is:
6 + 3x + 11 + 3x
=> 17 + 6x
Therefore, the total amount of pizza they make 5 hours after the first hour is:
17 + 6(5) = 17 + 30 = 47 pizzas

What are the zeros of (fx) =x^2-10x+25
Answer:
Zero of the function f(x) is x = 5
Step-by-step explanation:
Given function is f(x) = x² - 10x + 25
For zeros or x-intercepts of this function,
Put f(x) = 0
x²- 10x + 25 = 0
x² - 2(5)x + 5² = 0
(x - 5)² = 0 [Since, a² - 2ab + b² = (a - b)²]
x = 5
Therefore, x = 5 will be the zero of the given function.

At a summer camp,the ratio of campers to adults is kept equivalent to 7:1 use equivalent ratios to complete the table
Answer:
Campers: 7, 14, 28, 42
Adults: 1,2,5,30
Step-by-step explanation:
The tabular representation of the ratio of campers to adults in the summer camp is given as follows -
CAMPERS : 7 14 21 28 . . . . 7n
ADULTS : 1 2 3 4 . . . . n
We have a summer camp in which the ratio of campers to adults is kept equivalent to 7:1 .
We have to complete the table using the equivalent ratios.
How can you find out the equivalent ratios of the ratio a : b ?To find the equivalent ratios of a : b, follow the simple rule -
[tex]a:b=\frac{a}{b}=\frac{a\times2}{b\times2} =\frac{a\times3}{b\times3} =\frac{a\times4}{b\times4} = ... =\frac{a\times n}{b\times n}[/tex]
In the question given -
[tex]a:b=\frac{7}{1}=\frac{7\times2}{1\times2} =\frac{7\times3}{1\times3} =\frac{7\times4}{1\times4} = ... =\frac{7\times n}{n\times n}[/tex]
Hence, we can write the equivalent ratios in the form of tables -
CAMPERS : 7 14 21 28 . . . . 7n
ADULTS : 1 2 3 4 . . . . n

7) The senior classes at High School A and High School B planned separate trips to
Yellowstone National Park. The senior class at High School A rented and filled 2 vans
and 7 buses with 407 students. High School B rented and filled 1 van and 7 buses with
389 students. Every van had the same number of students in it as did the buses. How
many students can a van carry? How many students can a bus carry?
Answer:
Number of students in each van = 18
Number of students in each bus = 53
Step-by-step explanation:
Given: The senior class at High School A rented and filled 2 vans and 7 buses with 407 students.
High School B rented and filled 1 van and 7 buses with 389 students.
Also, every van and the van had the same number of students in it.
Solution:
Let x denotes number of students in each van and y denotes number of students in each bus.
According to the given information,
[tex]2x+7y=407\,\,\,(i)\\x+7y=389\,\,\, (ii)[/tex]
From (ii), put [tex]x=389-7y[/tex] in (i)
[tex]2(389-7y)+7y=407[/tex]
[tex]778-14y+7y=407\\778-407=7y\\7y=371\\y=\frac{371}{7}=53[/tex]
Put [tex]y=53[/tex] in [tex]x=389-7y[/tex]
[tex]x=389-7(53)\\=389-371\\=18[/tex]
Number of students in each van = 18
Number of students in each bus = 53

Find the zeros of the function. Write the smaller solution first, and the larger solution second f(x)=(x+2)2-16 smaller x larger x
Answer:
The solutions are x = -6 or x = +2
Step-by-step explanation:
In this question, we are asked to get the series of the equation given. we can find this by equating what we have to zero
Mathematically, we proceed as follows;
(x +2)^2 -16 = 0
This can be rewritten as;
(x + 2)^2 - 4^2 = 0
we can then proceed to use the difference of two squares to finish this off
Thus, we have
(x + 2 + 4)(x + 2 - 4) = 0
(x + 6)(x-2) = 0
X + 6 = 0 or x-2 = 0
x = -6 or x = +2

A rectangle has a height of 2x^4and a width of x^2+8x+15x
Answer:
2x⁶ + 16x⁵ + 30x⁴
Step-by-step explanation:
area of rectangle with height 2x⁴ and width x²+8x+15
area = height x width
2x⁴( x²+8x+15)
2x⁴( x²) +2x⁴(8x)+ 2x⁴(15)
2x⁴⁺² + 16x⁴⁺¹ + 30x⁴
2x⁶ + 16x⁵ + 30x⁴
the area of the rectangle in polynomial which is in standardised form is 2x⁶ + 16x⁵ + 30x⁴
Question: 5 ( x +20)= 7x +30
Answer:35
Simplifying
5(x + 20) = 7x + 30
Reorder the terms:
5(20 + x) = 7x + 30
(20 * 5 + x * 5) = 7x + 30
(100 + 5x) = 7x + 30
Reorder the terms:
100 + 5x = 30 + 7x
Solving
100 + 5x = 30 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
100 + 5x + -7x = 30 + 7x + -7x
Combine like terms: 5x + -7x = -2x
100 + -2x = 30 + 7x + -7x
Combine like terms: 7x + -7x = 0
100 + -2x = 30 + 0
100 + -2x = 30
Add '-100' to each side of the equation.
100 + -100 + -2x = 30 + -100
Combine like terms: 100 + -100 = 0
0 + -2x = 30 + -100
-2x = 30 + -100
Combine like terms: 30 + -100 = -70
-2x = -70
Divide each side by '-2'.
x = 35
Simplifying
x = 35
Hope it helps. Please tell me if im correct
Answer:
35
Step-by-step explanation:
5 * X= 5x
5* 20=100
these are for the ones inside the pararenthesis
so....
5x + 100= 7x+30
subtract 30 from both sides
5x+100-30= 7x-30-30
5x+70= 7x
now we need the variable on one side
so we subtract 5x on both sides
5x-5x+70= 7x-5x
70= 2x
now we divide by 2 on both to isolate the variable
70/2= 2/2
35=x
that's ur answer

Tony need 16 inch long pieces of gold chain to make each 3 necklaces. He has a peice of chain that is 4 1/2 long. How much chain will he have left after making the necklaces
Answer: 6 inches of chain will he have left after making the necklaces
Step-by-step explanation:
There is a missing information. The correct question is:
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces.
Solution
We would convert 4.5 feet to inches
1 foot = 12 inches
4.5 feet = 4.5 × 12 = 54 inches
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. It means that the number of the 16 inches pieces of gold chain that can be gotten to make each of 3 necklaces necklaces is 16 × 3 = 48
The length of chain left chain that will he have left after making the necklaces is
54 - 48 = 6 inches
