The solution to the system of linear equations is (-8, -2).
NOTE: The problem that is solved here is, 'What is the solution to this system of linear equations? Y - x = 6, Y + x = -10'
The equations with two variables and the largest exponent order of 1 each have one, zero, or an infinite number of solutions, and are referred to as linear equations.
A linear equation with two variables has the conventional form ax + by + c = 0, where x and y are the variables.
Additionally, the answers can be expressed as ordered pairs, like as (x, y). The system of linear equations in two variables is graphically represented by two straight lines, which may intersect, be parallel, or be coincident.
y - x = 6 ----> y = x + 6
y + x = -10 -----> y = - x - 10
As both the equations in terms of y, we get
x + 6 = - x - 10
By further calculation
x + x = - 10 - 6
2x = - 16
Dividing both sides by 2
x = -8
Substituting the value of x in either of the equations
y - x = 6
y - (-8) = 6
So we get
y + 8 = 6
y = 6 - 8
y = - 2
Therefore, the solution to the system of linear equations is (-8, -2).

A. The 3rd nap is the least consistent in duration because its mean is the lowest. B. The 2nd nap is the least consistent in duration because its standard deviation is the lowest. C. The 1st nap is the least consistent in duration because its mean is the highest. D. The 3rd nap is the least consistent in duration because its standard deviation is the highest.
UPDATED:
Plato users: answer is now A:
"The 3rd nap is the least consistent in duration because its
standard deviation is the highest."
they just shuffled the answers, the answer choice itself is still the same, just a dif letter choice
< 26 / Jan / 2022 >
The correct answer is the last one, that the 3rd nap is the least consistent in duration because its standard deviation is the highest.
What is the standard deviation?Standard deviation is a measure of variation from the mean; it tells how different values are from the mean.
We have given that,
A mother tracks the duration of her baby's three daily naps for a few weeks. The mean time, in minutes, and the standard deviation, SD, for each nap are recorded in the table below.
Now, For that nap to have a higher standard deviation means that its values were on average more different from the mean than the others.
Thus, The correct answer is the last one, that the 3rd nap is the least consistent in duration because its standard deviation is the highest.

Find the inverse of the function f(x) = 2÷3x -6
Answer:
f⁻¹(x) = 3/2x +9
Step-by-step explanation:
You want the inverse of the function f(x) = 2/3x -6.
Inverse functionThe inverse function can be found by solving for y:
x = f(y)
Here, that is ...
x = 2/3y -6
x +6 = 2/3y . . . . . . . . . . . . . . add 6
y = 3/2(x +6) = 3/2x +9 . . . . multiply by 3/2
The inverse function is f⁻¹(x) = 3/2x +9.
__
Additional comment
Sometimes the division symbol ÷ is used to mean "divided by everything after this symbol." If that is the intended meaning, the function should be written as f(x) = 2/(3x -6) or f(x) = 2÷(3x -6).
We have interpreted the symbol according to the order of operations, which tells us that 2÷3x-6 means ((2÷3)·x)-6.

What is PercentPercent is usually used to describe data in percentage form. This mathematical science is often used when calculating population percentages, discounts, interest rates, and so on. Percent is a number that represents part or all of the value or goods by forming a ratio of one hundred. Percent has an infinitely high value, while its lowest value is 0 percent. The amount of the percentage is denoted by "%".
History of Percent NumbersThis number was born in ancient Rome to be precise from the collection of auction taxes by using a fraction of 1/100 of the auction value or called centesima rerum venalium. the percent symbol has changed several times. Originally the Latin word percento was used. However, in the next generation, the word percento was changed to two symbols, namely the word per which changed to "/" and cento which changed to "00". Until finally the symbol "%" was known.
Percent formulaThe simple formula for calculating percent is: Percentage (%) = (Total parts)/(Total amount) X 100%. The general percentage formula for calculating the percentage of a number that is considered as part of the whole is written in percent or 100%.

What is recursion ?
It is a process in which it calls itself to solve the given problem is called as recursion.
The recursive formula to find the nth term of a geometric sequence is:
an = an-1 * r for n ≥ 2
In Brett's case,
if n=2
a2 = a1 * r
given a2 = 10 a1 =5
10 = 5 *d
d=2
a4 = a3 * d = 20*2 = 40
a5 = a4*d = 40*2 = 80
a6 = a5*d = 80*2 = 160
a7 = a6 * d = 160*2 = 320
In Yolanda case,
The recursive formula to find the nth term of an arithmetic sequence is:
an = an-1 + d for n ≥ 2
if n=2
a2 = a1 + d
60 = 25 + d
d = 35
a4 = a3+d = 95 + 35 = 130
a5 = a4+d = 130 + 35 = 165
a6 = a5+d = 165 + 35 = 200
a7 = a6 +d = 200 + 35 = 235
Hence the pattern in Brett's case could be 5,10,15,20,25,30,35 and in Yolando's case could be 25,60,95,130,165,200,235 .

The inequality that shows the relationship between thier heights is; g < r or r > g
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Now we have the following parameters that can be used in our computation:
Reese is taller than Gage.
Also, we have
Reeses's height = r
Gage's height = g
Since Reese is taller than Gage, then it means that
The value of r is greater than the value of g
So, we have the following inequality expression;
r > g
Also, we have;
g < r
Hence, the inequality is g < r

y varies inversely with x. If y = 40 when x = 16, find x when y = -5.
Suppose the following triangle is isosceles. Find the value of x.
Answer:
x = 62
Step-by-step explanation:
Because of the given congruent sides, the base angles both measure x.
x + x + 56 = 180
2x = 124
x = 62
if the triangle is an isosceles triangle then x is equal to the other angle that is unknown. So
180-56=124. Since there are still 2 angles left you divide 124/2=62
x=62

Write a division problem that has a quotient of 9/10 . At least one of the numbers you give must be a proper fraction. The other can be a proper fraction, whole number, or improper fraction. Neither the dividend nor the divisor can be 9/10 .
By dividing we can get proper fraction is 9/10.We can find answer by dividing two fractions.
What is proper fraction with example?A proper fraction is a fraction which has its numerator value less than the denominator. For example, ⅔, 6/7, 8/9, etc. are proper fractions.. We simplify fractions because it is always to work or calculate when the fractions are in the simplest form.
How do you divide fractions?To divide a fraction with a whole number we multiply the given whole number with the denominator of the fraction. Here, 8/5 ÷ 5 = 8/5 × 1/5 = 8/25. Therefore, 8/5 ÷ 5 = 8/25. Because multiplication is easier than division and because division by itself does not always produce whole numbers.

Answer: 78°
Similar triangles are different from congruent triangles. Congruent triangles have equal angles and sides, while similar triangles have equal angles and proportional side lengths. In this case, because the triangles are similar, the angles should be equal. The sum of the angles of triangles are always 180°. Because triangle ABC has angle measures of 28° and 74°, the equation should appear as 28+74+x=180. Add the like terms to get 102. Subtract 102 on both sides to get x=78. Although we only solved for Triangle ABC, again, similar triangles have the same corresponding angle measures, so it applies to Triangle DEF, as well.

express √832 in the form 4n where n is the integral
We can express √832 as 4(2√13).
What is definite integral?A definite integral of a function can be represented as the signed area of the region bounded by its graph.
Given is the root of 832 or √832.
Assume that {4n} is equal to {y}. So, we can write -
y = 4n
Squaring both sides, we get -
y² = (4n)² = (√832)²
y² = 16n² = 832
16n² = 832
n² = (832/16)
n² = 52
n = √52
n = 2√13
So, we can write (√832) as 4(2√13).
Therefore, we can express √832 as 4(2√13).
