The given equation is 2n = 2m + n and the proof is n = 2m
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to evaluate the given equation?The equation is given as
2n = 2m + n
Subtract n from both sides of the equation
So, we have
-n + 2n = 2m + n - n
Evaluate the like terms
n = 2m
Hence, the given equation is 2n = 2m + n and the proof is n = 2m

the sides of a triangle are 5:8:10 and it's perimeter is 23 cm. find the area of triangle.
Answer:
19.81cm^2
Step-by-step explanation:
To solve this, you need to use Heron's formula. Heron's formula solves for the area of a triangle given 3 sides defined as a, b, and c, as well as the perimeter. In this formula, p is half of the perimeter. The formula is:
sqrt(p*(p-a)*(p-b)*(p-c))
Plugging the values into this formula gives 19.81cm^2.

The scatterplot illustrates the relationship between two quantitative variables: the number of seeds planted per square foot and the yield of the crop (in pounds per square foot).
A graph titled Number of Seeds and Crop Yield has seeds (per square foot) on the x-axis, and yard (pounds per square foot) on the y-axis. The points curve up to a point, and then curve back down.
Which of the following is an accurate description of the scatterplot?
Answer:
I cannot confirm answer (D), but it looks correct to me.
Here's the option:
The expected yield of a crop is low whenever the number of seeds planted per square foot is small or large. A larger yield is expected when the number of seeds per square foot is around 60.

Correctly multiply (3x + 7) (7x + 5)
Then find the sum of the coefficients of your solution.
Answer:
The sum of the coefficients is 85.
Step-by-step explanation:
(3x + 7)(7x + 5)
3x * 7x is 21x^2
3x*5 is 15x
7 * 7x is 49x
7 * 5 is 35
21x^2 + 15x + 49x + 35
So the answer is 21x^2 + 64x + 35
Add the coefficients: 21 + 64 = 85

The measure of ∠BCD is 145°. The measure of ∠ABC is 65°.
What is measure of ∠BAC?
115°
35°
80°
145°
Answer:
m∠BAC = 80°Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°

18. what is the midpoint of PQ P(-2, 2.5), Q(1.4, 4)
Mid point of the points PQ is (₋0.3 , 3.25)
Given points are:
P(₋2 , 2.5)
Q(1.4 , 4)
midpoint of PQ = ?
A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.
The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.
Midpoint formula (x,y) = (x₁ ₊ x₂/2 , y₁ ₊ y₂/2)
we have two points:
P(₋2,2.5) = (x₁,y₁)
Q(1.4,4) = (x₂,y₂)
Midpoint = (₋2 ₊ 1.4/2 , 2.5₊4/2)
= (₋0.6/2 , 6.5/2)
= (₋0.3 , 3.25)
Hence we determined the midpoint of PQ as (₋0.3 , 3.25)

- Please help this is a Rational Inequality problem
1. A ball is thrown straight up from the top of a building that is 400 ft high with an initial velocity of 64 ft/s. The height of the object can be modeled by the equation s(t) = -16t^2 + 64t + 400. (solve step by step pls)
2. In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation.
The interval for the given situation is (0, 4).
Given that, height = 400 ft, initial velocity of 64 ft/s and the equation s(t) = -16t² + 64t + 400.
What is an initial velocity?Initial velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.
To find the interval in which the ball is higher than the building, solve the inequality h(t) > 400. The inequality is easily solved by subtracting 400 so the comparison is to zero, factoring the expression involving t, and identifying the time interval in which the signs of the factors are the same.
-16t² +64t +400 > 400
⇒ -16t² +64t > 0
⇒ -16t (t -4) > 0
⇒ t=0 and t-4=0
Both factors will have negative signs on the interval (0, 4).
Therefore, the interval for the given situation is (0, 4).

Find the 64th term of the arithmetic sequence -4, -21, -38, ...−4,−21,−38,...
Answer:
-1075
Step-by-step explanation:
The 64th term of the arithmetic sequence -4, -21, -38, .... is -1075.
What is Arithmetic Sequence?Arithmetic sequences are a set of numbers written in an order where the difference of any two consecutive term will be a constant. This constant difference between the consecutive terms is called the common difference commonly denoted by 'd'. In other words, arithmetic sequences are formed by adding or subtracting a constant number to each term.
Arithmetic sequences are also known as arithmetic progression.
Here, the given sequence is -4, -21, -38, ...
Common difference, d = (-21) - (-4) = -21 + 4 = -17
First term, a = -4
We have to find the 64th term of this sequence.
nth term of an arithmetic progression is given by the formula,
aₙ = a + (n - 1)d
a₆₄ = -4 + [(64 - 1) × (-17)]
= -4 + [63 × (-17)]
= -4 + (-1071)
= -1075
Hence the 64th term of the arithmetic sequence -4, -21, -38, .... is got as -1075.

− 14 n + q = r t − 4 n , for n
Answer:
n = q/10 - (r t)/10
Step-by-step explanation:
Solve for n:
q - 14 n = r t - 4 n
Subtract q - 4 n from both sides:
-10 n = r t - q
Divide both sides by -10:
Answer: n = q/10 - (r t)/10
