When combining like terms how do you know to add or subtract?
Answers
Answer:
It’s depends on the sign.
Step-by-step explanation:
For example if your question is 3x+16y-8-7x+8y then the answer would be -4x+24y-8 if they have the same variable look at them as a separate equation.
Answer:
"Like Terms" means that you can add or subtract two terms. For instance, you know that you can add and get 5. You were able to add these two 'terms' ( the '2' and the '3') because they are both numbers! However, you might also know that you cannot 'combine' 2 and x. Since 2 is a number and 'x' is not, they are not like terms.
Basically if its two numbers that are the same, For example (-2x and -4x) and have with the same variables you would add them. If they are like this (5x and -2x) you would subtract them because its a negative and positive number and get ( 3x).

The following system of linear equations is shown in the graph.

How many solutions does the system of linear equations have?
A. No solution
B. Infinitely many solutions
C. One solution at (4,0)
D. One solution at (0,-1)
Answers
Answer:
Step-by-step explanation:
The slopes of both those lines are the same so there is no solution. Use slope triangles to find out the slope. They are both 1/4.
A. No solution
y = 1/4x+5
x - 4y = 4
You can simplify the second equation into y = 1/4x - 1
Since these equations both have the same slope, they are parallel. When two lines are parallel, they have no solutions.
Write the equation of the line that has a slope of
3/5 and a y-intercept of 4.

Answers
Using the definition,
\(f'(4) = \displaystyle \lim_{x\to4} \frac{f(x)-f(4)}{x-4}\)
The numerator in the difference quotient is
\(f(x) - f(4) = \sqrt{2x+1} - \sqrt{2\cdot4+1} = \sqrt{2x+1}-3\)
Multiply the numerator and denominator by the conjugate of this expression,
\(\displaystyle \frac{\sqrt{2x+1}-3}{x-4} \cdot \dfrac{\sqrt{2x+1}+3}{\sqrt{2x+1}+3}\)
The modified numerator reduces to a difference of squares,
\(\displaystyle \frac{\left(\sqrt{2x+1}\right)^2-3^2}{(x-4)\left(\sqrt{2x+1}+3\right)}\)
Simplify this to get
\(\displaystyle \frac{2x+1-9}{(x-4)\left(\sqrt{2x+1}+3\right)} = \frac{2(x-4)}{(x-4)\left(\sqrt{2x+1}+3\right)}\)
Since x is approaching 4, it never actually takes on the value of 4, so (x - 4)/(x - 4) reduces to 1. Then the limit is equivalent to
\(f'(4) = \displaystyle \lim_{x\to4} \frac{f(x)-f(4)}{x-4} = \lim_{x\to4}\frac2{\sqrt{2x+1}+3}\)
and the remaining limand is continuous at x = 4, so that
\(f'(4) = \dfrac2{\sqrt{2\cdot4+1}+3} = \dfrac26 = \boxed{\dfrac13}\)

∠1 ​ and ∠2 are complementary. m∠1=x°m∠2=(3x 30)° what is the value of x? select from the drop-down menu to correctly answer the question.
Answers
The value of x is 15
If two angles sum to 90 degrees, they are said to be complimentary angles. In other terms, a right angle is created when two complementary angles are combined (90 degrees). If the sum of angles 1 and 2 equals 90 degrees (i.e., angle 1 plus angle 2 = 90°), then the angles are complementary and are referred to as one another's complements.
∠1 and ∠2 are complementary angles i.e the sum of ∠1 and ∠2 is 90° .
Thus
∠1 + ∠2 = 90°
x° + (3x+30)° = 90°
x + 3x + 30 = 90
4x = 90-30
4x = 60
x = 15
Therefore the value of x is 15.

Answers
In conclusion, a) it is an odd permutation, b) it is an even permutation, c) it is an even permutation, d) it is an even permutation and e) it is an odd permutation.
To determine whether a permutation is even or odd, we need to count the number of transpositions it can be written as.
a) (1235)(24567): This permutation can be written as (12)(13)(15)(24)(25)(26)(27), which consists of 7 transpositions. Therefore, it is an odd permutation.
b) (345)(245): This permutation can be written as (34)(35)(24)(25), which consists of 4 transpositions. Therefore, it is an even permutation.
c) (1243)(3521): This permutation can be written as (12)(14)(13)(24)(35)(51)(52)(21), which consists of 8 transpositions. Therefore, it is an even permutation.
d) (12345)(123)(45): This permutation can be written as (15)(14)(13)(12)(45)(23), which consists of 6 transpositions. Therefore, it is an even permutation.
e) (13)(24567): This permutation can be written as (13)(24)(25)(26)(27), which consists of 5 transpositions. Therefore, it is an odd permutation.

The relationship between the number of days and

The equation allows us to chart the tree's development over time and forecast its ultimate height.
what is function ?A function is a mathematical formula that allots each input from one set, known as the domain, to precisely one output from another set, known as the range. A function can be used to model relationships between variables, answer issues, and make predictions. It can be represented by an equation, a graph, a table, or a verbal description. Numerous branches of mathematics, as well as disciplines like physics, engineering, finance, and computer science, make extensive use of functions. Typical instances of functions include: When a function is graphed, it always changes at the same rate and forms a straight line. They are frequently used to simulate relationships between two variables that are related linearly, such as time and location.
given
After d days, Alani created the following algorithm to measure the height of the banana tree:
h = d + 8
Since this function is linear, the banana tree's development will remain constant over time. According to the calculation, the tree starts out at a height of 8 units, and it increases by 1 unit per day after that.
We can enter a figure for d (the number of days) and solve for h using this equation (the height of the tree after d days). For instance, we can enter d = 10 into the calculation to get the height of the tree after 10 days:
h = 10 + 8
h = 18
Therefore, the altitude of the banana plant after 10 days would just be 18 units. This equation allows us to chart the tree's development over time and forecast its ultimate height.

Answers
The solution to the equation √x = 6 is x = 36.
What is equation?
An equation is a mathematical statement that shows the equivalence of two expressions. It typically includes variables, represented by letters, that can assume different values, as well as constants and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation.
To solve the equation √x = 6, we need to isolate x on one side of the equation.
One way to do this is to square both sides of the equation, since squaring both sides will eliminate the square root:
(√x)² = 6²
Simplifying the left side by applying the property that (√a)² = a, we get:
x = 36
Therefore, the solution to the equation √x = 6 is x = 36.
