Like terms are terms that have same variable. For example:
2x and x are like terms because they have same variable which is x. y and 3y both are like terms because they have same variable which is y. 2x and y both are not like terms because x-term and y-term are not the same variable or term.The thing that you need to becareful is about the degree. Even though x² and x both are also x-term, but they are not considered like terms. So basically like terms are terms that have same variable and same degree.
Given the expression below:
[tex] \large{2x + 2y + {x}^{2} - x + {x}^{2} }[/tex]
From the expression:
2x and x are like terms.x² and x² are also like terms.Arrange in better form for our calculation.
[tex] \large{(2x - x) + 2y + ( {x}^{2} + {x}^{2} )} \\ \large{x + 2y + 2 {x}^{2} }[/tex]
You might also want to arrange the expression degree (optional but recommended).

A researcher gathered data on hours of video games played by school-aged children and young adults. She collected the following data:
16 11 12 10 0 12 8 4 1 0
13 0 2 4 2 6 17 11 10 14
8 3 10 7 1 13 4 7 1 13
5 5 12 2 16 13 9 9
Complete the frequency distribution for the data.
Hours Frequency Relative Frequency
0-2
3-5
6-8
9-11
12-14
15-17
Step-by-step explanation:
The complete frequency distribution table for the data has been attached to this response.
The frequency column contains values that are the number of times the given range of hours appear in the data. For example, numbers in the range 0 - 2 hours, appear 9 times in the data. Also, the numbers in the range 3 - 5 appear 6 times. The same logic applies to other ranges.
The relative frequency column contains the ratio of the number of times the given range of hours appear in the data, to the total number of outcomes. The total number of outcomes is the sum of all the frequencies on the frequency column. This gives 38 as shown.
So, for example, to get the relative for the numbers in the range 0-2, divide their frequency (9) by the total outcome or frequency (38). i.e
9 / 38 = 0.24
Also, to get the relative for the numbers in the range 3-5, divide their frequency (6) by the total outcome or frequency (38). i.e
6 / 38 = 0.16
Do the same for the other ranges.

3^x = 7
Answer:
1.771
Step-by-step explanation:
log 3^x = 7
x log3 = log 7
divide both sides by log3
x = log7 / log 3
x = 1.771
Answer:
Answer of given question is 1.771
Step-by-step explanation:
Given :
[tex]3^x=7[/tex]
Taking log on both side
[tex]log(3^{x} )=log 7\\xlog3=log7\\x=\frac{log7}{log3} \\x=1.7712[/tex]
Therefore, answer of the given question is 1.771
Consider the following function:
f(3) = log2(x + 3)
Which interval has the smallest average rate of change in the given function?
O (0,2
O 4,6]
O [2,4
O (6,8)
In the function f(x) = log2(x + 3)), the smallest average rate of change in the function is in the interval, (6,8)
What is a logarithmic function ?The logarithmic function is an expression which we can write as, y = logₐx, where a>0 & x>0, It is the inverse of exponential function.
Formulae for logarithmic function are,
LogAB = LogA + LogB
Logₐaᵇ = b
Given that,
A logarithmic function,
f(x) = = log2(x + 3)
Rate of change = Change in values of function/change in x
= [F(b) - F(a)]/ b-a
For the interval, (0, 2)
f(0) = Log2(0 + 3) = Log(6)
f(2) = Log2(2 + 3) = Log(10)
Rate of change = Log(10) - Log(6) /2
= 0.11
Similarly, for the intervals, (4, 6), (2, 4), (6,8)
Hence, the smallest average rate is for the interval, (6, 8)

dos caños A y B llenan juntos una piscina en dos horas, A lo hace por si solo en tres horas menos que b ¿Cuantas horas tarda cada uno separadamente?
Answer:
t² - 7 t + 6 = 0; es una ecuación de segundo grado en t. Sus raíces son: t = 6, t = 1; la segunda solución es físicamente imposible. Uno solo de ellos no puede llenar la piscina en menos tiempo que los dos juntos. Por lo tanto uno de ellos demora 6 horas y el otro 6 - 3 = 3 horas.

Answer:
x = 5y = 30z = 8Step-by-step explanation:
The rhombus has several relevant properties.
The sides are all the same lengthDiagonals are perpendicular bisectors of each otherDiagonals divide the rhombus into congruent trianglesThe last of these relations can be used to find x:
7x° = 35°
x = 35°/7° = 5
The second of the relations can be used to find y:
3y° = 90°
y = 90°/3° = 30
The first of the relations can be used to find z:
10z -8 = 5z +32
5z = 40 . . . . . . . . . add 8-5z
z = 40/5 = 8

A restaurant needs a staff of 3 waiters and 2 chefs to be properly staffed. The joint probability model for the number of waiters (X) and chefs (Y) that show up on any given day is given below. X Y 0 1 2 3 0 k 0.01 0.01 0.03 1 0.02 0.04 0.04 0.06 2 0.02 0.01 0.06 0.63 a) What must the value of k be for this to be a valid probability model
Solution :
Given the Joint Probability distribution is :
Y|X 0 1 2 3 P(y)
0 k 0.03 0.03 0.03 k+0.09
1 0.01 0.02 0.04 0.04 0.11
2 0.01 0.01 0.05 0.72 0.79
P(x) k+0.02 0.06 0.12 0.79 k+0.99
Since we know,
[tex]$\sum \sum P(x_i,y_j) = 1$[/tex]
⇒ k + 0.99 = 1
⇒ k = 1 - 0.99
⇒ k = 0.01
Therefore, the value of k is 0.01

[tex]\frac{cot x}{tanx+cot x}=cos^2x[/tex]
csc^2θ·tan^2θ - 1 = tan^2θ
Step-by-step explanation:
a)
[tex] \frac{1 + \sin y}{ \cos y} + \frac{ \cos y}{1 + \sin y} = \frac{1 + 2 \sin y + \sin^{2} y + \cos ^{2} y}{ \cos y(1 + \sin y)} [/tex]
[tex] = \frac{2 + 2 \sin y}{ \cos y (1+ \sin y)} = \frac{2}{ \cos y} = 2 \sec y[/tex]
b)
[tex] \frac{ \cot x}{ \tan x + \cot x} = \frac{ \cos x}{ \sin x( \frac{ \sin x}{ \cos x} + \frac{ \cos x}{ \sin x} )} [/tex]
[tex] = \frac{ \cos x}{ \frac{ \sin^{2} }{ \cos x} + \cos x } = \frac{ \cos x}{ \frac{ \sin ^{2} x + \cos^{2} x}{ \cos x} } [/tex]
[tex] = \cos ^{2} x[/tex]
c) Note that cscx = 1/sinx so
[tex] \csc^{2} \theta \tan^{2} \theta - 1= \frac{1}{ \cos^{2} \theta } - 1[/tex]
[tex] = \frac{1 - \cos^{2} \theta }{ \cos \theta} = \frac{ \sin^{2} \theta}{ \cos ^{2} \theta } = \tan^{2} \theta[/tex]
Which of the following is a point-slope equation of a line that passes through the points (-1,4) and (8,-2)
Answer:
y = (2/3)x + 4 2/3
Step-by-step explanation:
For reference, a linear function has an equation of y = mx + b
The first thing we're going to do is use the slope formula, [tex]\frac{y2-y1}{x2-x1}[/tex] or rise over run. In this case that looks like:
(-2-4) - (8 - -1)
-2 -4 comes out to - 6, and the denominator comes out to 9.
6/9 is equal to 2/3, which is our m or slope value.
Next we want to find the b value, or our y-intercept. To do that we'll plug one of the points into the equation with our new-found slope:
4 = (2/3)-1 +b
4 = -2/3 + b
4 2/3 = b
That means our complete equation is:
y = (2/3)x + 4 2/3
OR
y = (2/3)x + 14/3 (equivalent but an improper fraction rather than a mixed fraction).

Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same, and this difference is called common difference.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + d(n-1)[/tex]
In which [tex]a_1[/tex] is the first term and d is the common difference.
In this question:
[tex]a_1 = 5, d = 4[/tex]. So
[tex]a_n = a_1 + d(n-1)[/tex]
[tex]a_n = 5 + 4(n-1)[/tex]
Find the value of a_5
[tex]a_n = 5 + 4(n-1)[/tex]
[tex]a_5 = 5 + 4(5-1) = 5 + 16 = 21[/tex]
So
[tex]a_5 = 21[/tex]
The [tex]a_{5}[/tex] term of an arithmetic sequence is 21.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant, and this difference is called the common difference.
The nth term of the sequence is given by
[tex]\rm a_{n} =a_{1} + (n-1)d\\[/tex]
[tex]a_{1}[/tex]= the first term of the sequence and d is a common difference.
[tex]\rm a_{1} = 5, d=4\\\rm a_{n} =a_{1} + (n-1)d\\\rm a_{n} = 5 + 4(n-1)\\\rm a_{5} = 5 + 4(5-1)\\\rm a_{5} = 21[/tex]
Therefore, The [tex]a_{5}[/tex] term of an arithmetic sequence is 21.

find a diginacci sequence with no equal term to 11: quick answer please
Answer:
uhh hope this helps
Step-by-step explanation:
A Diginacci sequence is created as follows.
• The first two terms are any positive whole numbers.
• Each of the remaining terms is the sum of the digits of the previous
two terms.
For example, starting with 5 and 8 the Diginacci sequence is
5, 8, 13, 12, 7, 10,. . .
The calculations for this example are
5 + 8 = 13, 8 + 1 + 3 = 12, 1+ 3 +1+ 2 = 7, 1 + 2 + 7 = 10.
a) List the first 26 terms of the Diginacci sequence above.
b) Find, with explanation, two starting terms for a Diginacci sequence
so that its 2021st term is 11.
c) Find, with explanation, a Diginacci sequence that has no term equal
to 11.
d) Find, with explanation, a sequence with two different starting terms
which contains five consecutive terms that are even and not all identical
Both 2 and 3 is correct.
