Question 1:
Are x2 and x like terms?
Are 4x and 2x like terms?
Are 2x and 2y like terms?
Are 3x2 and 6x2 like terms?
[tex] \large{ \tt{❃ \: EXPLANATION}} : [/tex]
- [tex] \large{ \boxed{ \tt{LIKE \: AND \: UNLIKE \: TERMS}}}[/tex]
Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted. For instance : We can say 4y and 5y are like terms as they have the same base i.e y Unlike terms are those which have the different base. Unlike terms can neither be added nor subtracted. For instance : We can say 4x and 6y are unlike terms as they have the different base i.e 4x has the variable x while 6y has the variable y.[tex] \large{ \tt{❊ \: LET'S \: START}} : [/tex]
No , x² and x are not like terms since they don't have same base.Yes , 4x and 2x are like terms since they have the same base.No , 2x and 2y are not like terms since they have different base. Yes , 3x² and 6x² are like terms since they have the same base .[tex] \tt{✺ \: BE \: IN \: LOVE \: WITH \: YOUR \: LIFE !\: ♪}[/tex]

Find the x-intercept and the y-intercept of the graph equation 7x +3y =21 type a integer
Answer:
7(y intercept)
Step-by-step explanation:
y = mx +c form
y = 21-7x/3
c = 21/3 = 7(y intercept)
x i have no idea
To find x-intercept ,put y= 0 in the given eqn
So, 7x+3(0) = 21
=> 7x =21
=> x= 21/7 = 3
x-intercept = 3
Similarly, to find y-intercept put x=0 in the given eqn
So ,7(0)+3y=21
=> 3y=21
=> y= 21/3 = 7
y-intercept = 7
simplify this fully x+x+y×y
Answer and Step-by-step explanation:
The answer would be 2x + 2y.
This is because we combine the x's together and the y's together. This is the simplest form of the expression.

Step-by-step explanation:
To solve for q, we apply the leg rule theorem :
The hypotenus = 10 + 4 = 14
Leg 1 = q
Part1 = 4
According to the leg rule theorem :
Hypotenus / leg 1 = leg 1 / part 1
14 / q = q / 4
Cross multiply :
q * q = 14 * 4
q² = 56
q = √56
√56 = √4 * √14 = 2√14

in a recent year, 21.2% of all registered doctors were female. if there were 42,800 female registered doctors that year, what was the total number of registered doctors?
Answer:

Step-by-step explanation:
Janet and Patrick surveyed a total of 219 people. Out of the 137 girls who were surveyed, 28 said summer was their favorite season and 12 said that winter was their favorite.
The results showed 22 boys said that spring was their favorite season and 8 boys said winter was their favorite.
A total of 45 people said that summer was their favorite season and a total of 74 people said that fall was their favorite season.
In this activity, you will construct two-way frequency tables to help Janet and Patrick analyze the data they gathered from their survey.
Part A
Create a two-way frequency table to represent the results of the survey by entering the appropriate data in each box.
Answer: See figure 2 in the diagram below for the table.
==========================================================
Explanation:
The steps are fairly lengthy to explain in words, but the process is fairly straightforward. Start with figure 1 in the diagram below. The letters A through O represent the steps you'll take to replace them. For instance, you'll replace A with 219 since that's the grand total. Then B is replaced with 137 since we're told that 137 girls were surveyed. Then C gets replaced with 219-137 = 82, and so on. Use arithmetic (adding and subtracting) to gradually replace each letter with the proper number as figure 2 shows. The alphabetical order directly corresponds to the order in which the values are given by your teacher (eg: 219 is first, then 137 next, and so on).
Let me know if you get stuck on any one step, or need me to go into more detail.

Fraser scores 70% in a spelling test with 20 questions. How many did he get right? (Working out please)
Answer:
He got 14 right
Step-by-step explanation:
Percent means out of 100
70% means 70/100
We know there were 20 questions
We can write a ratio
70/100 = x /20
Using cross products
70*20 = 100x
1400 = 100x
Divide by 100 on each side
1400/100 = 100x/100
14 =x
He got 14 right
Answer:
I believe he got 14 right and 6 wrong
Step-by-step explanation:
if 10% is 2 questions each question is worth 5 points to make up of 100 (100 divided by 20 = 5) and there are 100 points in the quiz then every 2 right would be 10% count until you get 70% and you got your answer :) please mark brainliest and have a good day

HELP!! Create a system of equations with the solution (-4, 1)
9514 1404 393
Answer:
x -y = -5
3x +y = -11
Step-by-step explanation:
We assume you want two linear equations. Since you know a point on each line, the only thing you need to choose is the slope of the two lines through that point. We can make the slopes be +1 and -3, for example. Then the point-slope equations are ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -1 = +1(x +4)
y -1 = -3(x +4)
We can use these equations "as is", or put them in whatever form you like. I personally prefer "standard form:" ax+by=c.
First equation:
y -1 = x +4 . . . . . . eliminate parentheses
-5 = x -y . . . . . . . keep positive x term, put x and y together, separate from the constant
x - y = -5 . . . . . . standard form
Second equation:
y -1 = -3x -12 . . . . eliminate parentheses
3x +y = -11 . . . . . . add 3x+1 to both sides
__
A system of equations with solution (-4, 1) is ...

The surface area of a square pyramid is 125 square feet. The base length is 5 feet. What is the slant height?
Answer:
10.31 ft
Step-by-step explanation:
the base is 25 ft²
leaves 100 ft² for the 4 sides on top
so each triangle got 25ft²
the base length of the triangle is 5ft, bc it's the base length of the pyramid
so the height of the triangle is 10ft,
bc only then do we get a surface area of 25ft²
(b * h /2) for the triangle
now that we got base length and height,
let's look for the slant
we recall the pythagoras stuff to get the missing side of the triangle. but notice that we need to split the triangle in half to get a 90° angle.
leaving us with 10ft (height) and 2.5ft
slant² = 10² + 2.5²
slant² = 106.25
slant = sqrt(106.25)
slant = 10.31

A Ferris wheel completes 7 revolutions in 14 minutes. The radius of the Ferris wheel is 30 feet.
What is the linear velocity of the Ferris wheel in inches per second?
Enter your answer, rounded to the nearest tenth, in the box.
The linear velocity of the Ferris wheel in inches per second is 18.9 inches/second.
What is the speed of an object?The speed of an object is the ratio of the total distance covered by the object and total time taken by the object to complete that distance.
Here, the radius of the Ferris wheel is (r) = 30 feet.
The circumference of the wheel is
= 2πr
= 2 × π × 30 feet
= 60π feet
Here, the Ferris wheel completes 7 revolutions.
Therefore, it covers the linear distance of
= 7 × circumference of the wheel
= 7 × 60π feet
= 420π feet
Now, the Ferris wheel took 14 minutes to complete 420π feet.
Therefore, the speed of the wheel is
= (420π/14) feet/minute
= 30π feet/minute
= (30π × 12)/60 inches/second
= 6π inches/second
= 18.9 inches/second

It is used to estimate the population mean. C. sis the sample standard deviation. It is the square root of the variance. O D. nis the sample size. It is used to calculate the sample mean. SUBMIT
Using the Central Limit Theorem, the false statement is given by:
B. [tex]\mu[/tex] is the sample mean. It is used to estimate the population mean.
What does the Central Limit Theorem state?It states that, for a normally distributed random variable X, with population mean [tex]\mu[/tex] and population standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard error [tex]s_E = \frac{\sigma}{\sqrt{n}}[/tex].
If we have the standard deviation for the sample s, the Central Limit Theorem can also be applied.
The sample mean is given by [tex]\overline{x}[/tex], hence option B is false.

Is the following statement possible or impossible?
Impossible
Hope this helps! :)
Answer:
Impossible
Step-by-step explanation:
Based on the Inequality Theorem, in any triangle, the sum of any two sides will be larger than the length of the thrid side. If the side lengths do not follow this rule, then that means that you can not create a triangle with such side lengths. In our case, the sum of two sides with lengths 1 and 8 is 1 + 8 = 9 and 9 is not greater than the length of the third side which is also 9. Therefore, it is impossible to build a triangle with such lengths.
Do 7, 8, and 9 form a right triangle?
Answer:
No, 7, 8 and 9 do not form a right triangle.
Step-by-step explanation:
Assume that the shorter two side lengths are 7 and 8. Does 7^2 + 8^2 add up to 9^2? Does 49 + 64 add up to 81? NO.
No, 7, 8 and 9 do not form a right triangle.
