Write an explicit formula for each arithmetic sequence. -2,7,16,25, . . .
Explicit formula is [tex]a_{n}[/tex] =a + (n-1)d
Here in the explicit formula of the sequence -2, 7, 16, 25....
Formula
[tex]a_{n}[/tex] = a +(n-1)d
In the formula, n is any term number and a(n) is the nth term.
This formula allows us to simply plug in the number of the term we are interested in, and we will get the value of that term.
To find the 5th term, for example, we need to plug n = 5 into the explicit formula.
common difference(d) = 7 - (-2) = 16- 7 = 9
[tex]a_{5}[/tex] = -2 + 9( 5-1)

How to solve:
7k + 6-3 = -4
Please show steps! (:
answer:
k= -1
Step-by-step explanation:
7k+3=-4
7k=-3-4
7k=-7
1k= -1
Given equation,
→ 7k + 6 - 3 = -4
Now solving for value of k,
→ 7k + 6 - 3 = -4
→ 7k + 3 = -4
→ 7k = -4 - 3
→ k = -7/7
→ [ k = -1 ]
Hence, the value of k is -1.

A store owner wants to develop a new snack mix by mixing chocolate and trail mix. how many pounds of chocolate costing $20.10 per pound should be mixed with 25 pounds of trail mix costing $2.80 per pound to create a mixture worth $8.41 per pound.
If a store owner wants to develop a new snack mix by mixing chocolate and trail mix, then the number of pounds of chocolate costing $20.10 per pound that should be mixed with 25 pounds of trail mix costing $2.80 per pound to create a mixture worth $8.41 per pound is equal to 11.99.
The pounds of chocolate needed to create a mixture worth $8.41 per pound can be calculated using an algebraic expression.
An algebraic expression can be defined as an expression consisting of both numbers and letters.
If x = the unknown pounds of chocolate
An algebraic expression can be given as,
20.10x + 2.80(25) = 8.41(x + 25)
Solving for x,
20.10x + 70 = 8.41x + 210.25
Rearranging,
20.10x - 8.41x = 210.25 - 70
11.69x = 140.25
x = 140.25 ÷ 11.69
x = 11.99
Hence, 11.99 pounds of chocolate costing $20.10 per pound should be mixed with 25 pounds of trail mix costing $2.80 per pound to create a mixture worth $8.41 per pound.

Winston needs at least 80 signatures from students in his school before he can run for class president. He has 23 signatures are ready. He and two of his friends planted the remaining sutures during lunch. If each Person gets the same number of signatures, which inequality can Winston use to determine the minimum number of signatures each person should get so he can run for class president?
The inequality that Winston can use to determine the minimum number of signatures is 3x ≥ 57.
What is the inequality?The first step is to determine which inequality sign would be used.
The following are inequality signs and what they mean:
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
The sign that would be used is the greater than or equal to sign - ≥ . This is because the number of signatures can be either equal to 80 or greater than 80.
The next step is to determine the least number of signatures needed : 80 - 23 = 57

Use the symmetric property of congruence to complete the following statement.

By the symmetric property of congruence is ∠FSJ ≅∠UPR.
It is required to find the solution.
What is symmetry ?Symmetry is defined as a proportionate and balanced similarity that is found in two halves of an object, that is, one-half is the mirror image of the other half. A 2D shape is symmetrical if a line can be drawn through it and either side is a reflection of the other.
Given:
The symmetric property is if y = x then x = y. The order of what is on the left or right side of the equation does not matter. It's like saying 2+3 = 5 is the same as 5 = 2+3.
According to given question we have,
This idea can be extended to congruences because congruent angles have the same measure.
Congruent angles are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other.
So, ∠UPR ≅∠FSJ, then ∠FSJ ≅∠UPR.
Therefore, by the symmetric property of congruence is ∠FSJ ≅∠UPR.

A new long-life tire has a tread depth of 7/16 inches, instead of the more typical 7/32 inches. How much deeper is the new tire?
Answer: The new tire is 7/32 of an inch deeper, or twice as deep.
Step-by-step explanation: The answer can be found by subtracting the old tire length from the new tire length. We must first find a common denominator. To do that, we multiply both the top and bottom of 7/16 by two and get 14/32. Now we subtract 7/32 (old tire) from 14/32 (new tire) to get 7/32.

The three types of congruence transformations are rotation, reflection, and translation is TRUE.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
A triangle will remain congruent if we rotate it by any angle in either a clockwise or counterclockwise manner.
If we transform by any amount either horizontal or vertical then it will remain the same so it will be congruent.
A triangle will remain the same if we mirror it on any axis, making it congruent.
Hence "The three types of congruence transformations are rotation, reflection, and translation is TRUE".

Find the 10 th term of each geometric sequence. a₁₁ =-5, r=-1/2
The 10th term of the geometric sequence with a(11) = -5 and r = -1/2 is a(10) = 10.
A geometric sequence is a sequence of numbers where the nth term is obtained by multiplying the (n-1)th term by a constant, called a common ratio (r). Mathematically, it can be expressed as:
a(n) = a(n-1) . r
So, if a(1), a(2), a(3), ..., a(n) is a geometric sequence, then:
a(2) = a(1) . r
a(3) = a(1) . r
and so on.
In the problem, the given parameters are: a(11) = -5 and r = -1/2, and we need to find a(10).
Using the above recursion:
a(11) = a(10) . r
-5 = a(10) . (-1/2)
Multiply both sides by (-2)
-5 . (-2) = a(10) . (-1/2) . (-2)

Solve each equation. Check each solution. 4/x+3=5
The solution of the equation 4/x+3=5 is at x = -11/5.
According to the given question.
We have an equation 4/x+3=5.
As we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.
Therefore, the solution of the equation 4/x+3=5.
4/x+3 = 5
⇒ 4 = 5(x + 3) (multiplying both the sides by x + 3)
⇒ 4 = 5x + 15 (by distributive rule)
⇒ 4 - 15 = 5x
⇒ -11 = 5x
⇒ x = -11/5
Hence, the solution of the equation 4/x+3=5 is at x = -11/5.
