If f(x) = x + 2, find the value of x if f(x) = 12.

Answers

Answer 1

Hello,

Let's plug in "12" for "f(x)" since they tell us:
12 = x +2.

Now, in order to get "x" by itself, we add 2 to each sides:
12 +2 = x, which then becomes x = 14.

Hope this helps!

First option

Answer:

[tex]x^2-11x + 13[/tex]

Step-by-step explanation:

Let [tex]f(x) = 2x^2 - 2x + 7[/tex] and [tex]g(x) = x^2 + 9x - 6[/tex]

We need to find f(x)- g(x)

Replace f(x) and g(x). then subtract the expressions

[tex]f(x)-g(x) =(2x^2 - 2x + 7)- (x^2 + 9x - 6)[/tex]

Remove the parenthesis and multiply negative sign inside second parenthesis

[tex]2x^2 - 2x + 7- x^2 - 9x + 6[/tex]

What is the difference between -5 squared and -5 parenthesis squared?

Answers

-5 is essentially -1·5

Order of operations says to do exponents first, so without parentheses -5², you would square first then multiply by -1, leaving you with an answer of -25.

However, parentheses comes before exponents in order of operations, so with parenthesis (-5)² would be 25.

Given that line bd is both the median and altitude of triangle abc, congruence postulate sas is used to prove that triangle abc is what type of triangle

Answers

isosceles triangle

hope this helps :)

Answer:

Triangle ABC is an isosceles triangle.

Step-by-step explanation:

Let AD represent both the median and altitude of triangle ABC.

A median divides the side in two equal parts so BD=BC.

An altitude is a perpendicular drawn .A perpendicular makes an angle of 90°. Hence <ADB=<ADC=90°

AD is the side common to both the triangles ADB and ADC.

Hence Δ ADB≅ΔADC by SAS congruence postulate.

So AB=AC by c.p .c .t.c(congruent parts of congruent triangles are congruent)

Hence by definition of Isosceles triangle ΔABC is an isosceles triangle.

Why do astronomers say that the sun rotates once every 27 to 31 days, rather than give an exact number?

Answers

Astronomers cannot give an exact answer about how long it takes the sun to rotate because of the sun's matter. The sun is made up of gas and plasma, these types of matter have different weight than the solids that most planets are made out of. Different parts on the sun move at different speeds giving a range of days for the sun's rotation.

Astronomers provide a range for the Sun's rotation period due to differential rotation, with varying speeds at different latitudes.

This question demands basic understanding of planetaty motion i.e rotation and revolution in general and about motion of sun in particular

Astronomers say that the Sun rotates once every 27 to 31 days because of the phenomenon known as differential rotation. This means that the speed of rotation of the Sun varies based on its latitude.

The rotation period of the Sun is about 25 days at the equator, 28 days at latitude 40°, and 36 days at latitude 80°. Due to this variable rotation speed, astronomers provide a range rather than an exact number for the Sun's rotation period.

Does tis table represent a function ?

Answers

The answer is A. This can be seen in the table where y can be both 4 and 3 for when x = 3. In a function, an output can have more than one input, but an input can have have only one output.

Answer: A function is so F(X) = Y where for every X exist only one Y, in this case you can see that F(3) = 4 and F(3) = 3, so the independent variable x = 3, has two solutions y.

So the solution is A, because a function cannot have two different y values for one x value.

Ryan made 4 identical necklaces, each having beads and a pendant. the total cost of the beads and pendants for all 4 necklaces was $18.80 . if the beads cost a total of $9.20 , how much did each pendant cost?

Answers

Write an equation to show all elements:

Cost of 4 lots of b (beads) + cost of 4p (pendants) = $18.80

Put values in;
9.29 + 4p = 18.80
4p = 18.80 - 9.20
4p = 9.60
p = 2.40 cost of each pendant

What's the intuition behind the equation 1+2+3+⋯=−1121+2+3+⋯=−112 ?

Answers

The sum clearly diverges. This is indisputable. The point of the claim above, that

[tex]1+2+3+\cdots=-\dfrac1{12}[/tex]

is to demonstrate that a sum of infinitely many terms can be manipulated in a variety of ways to end up with a contradictory result. It's an artifact of trying to do computations with an infinite number of terms.

The mathematician Srinivasa Ramanujan famously demonstrated the above as follows: Suppose the series converges to some constant, call it [tex]C[/tex]. Then

[tex]\begin{matrix}C&=&1&+2&+3&+4&+5&+6&+\cdots\\4C&=&&+4&&+8&&+12&+\cdots\\-3C&=&1&-2&+3&-4&+5&-6&+\cdots\end{matrix}[/tex]

Now, recall the geometric power series

[tex]\displaystyle\sum_{n\ge0}x^n=1+x+x^2+x^3+\cdots=\dfrac1{1-x}[/tex]

which holds for any [tex]|x|<1[/tex]. It has derivative

[tex]\displaystyle\sum_{n\ge1}nx^{n-1}=1+2x+3x^2+4x^3+\cdots=\dfrac1{(1-x)^2}[/tex]

Taking [tex]x=-1[/tex], we end up with

[tex]1+2(-1)+3(-1)^2+4(-1)^3+\cdots=1-2+3-4+\cdots=\dfrac14[/tex]

and so

[tex]-3C=\dfrac14\implies C=-\dfrac1{12}[/tex]

But as mentioned above, neither power series converges unless [tex]|x|<1[/tex]. What Ramanujan did was to consider the sum [tex]1-2+3-4+\cdots[/tex] as a limit of the power series evaluated at [tex]x=-1[/tex]:

[tex]\displaystyle-3C=\lim_{x\to-1^+}\sum_{n\ge1}nx^{n-1}=\lim_{x\to-1^+}\frac1{(1-x)^2}=\frac14[/tex]

then arrived at the conclusion that [tex]C=-\dfrac1{12}[/tex].

But again, let's emphasize that this result is patently wrong, and only serves to demonstrate that one can't manipulate a sum of infinitely many terms like one would a sum of a finite number of terms.

First, you need to find the slope (m) =3 and your slope intercept form being y=mx+b; look for the one that says y=3x+__. don't use this every time because there could be T that say it.

Why do two negatives equal a positive when adding?

Answers

Two negatives do not equal a positive when adding. If you're in debt and you add more debt, does that get you out of debt?

Two negatives do equal a positive when you're multiplying them together though. This makes sense if you imagine multiplication as squishing or stretching a particular number on the number line. For example, imagine multiplying 2 x 1/2 as squishing the number 2 two times closer to 0. When you multiply 2 by a negative number, say, -1, you squish it so far down that you flip it to the negative side of the number line, bringing it to -2. You can imagine a similar thing happening if you multiply a number like -4 by -2. You squish -4 down to zero, and then flip it to the positive side and stretch it by a factor of 2, bringing it to 8.

18 girls out of 32 students is what percent?

Answers

18 girls represent 56.25 percent of the total number of students.

To find what percent 18 girls out of 32 students represent, you can set up a proportion comparing the number of girls to the total number of students. This proportion is represented by the fraction 18/32. To convert this fraction into a percentage, multiply it by 100.

Here's the calculation step by step:

Divide 18 by 32 to get the decimal form.

Multiply the result by 100 to get the percentage.

Performing the calculation gives:
(18/32) x 100 = 56.25%

Therefore, 18 girls represent 56.25 percent of the total number of students.

Mario fills out an information card. His Zip code is 83628. His area code is 208. What is the value of the 2 in comparison in 83,628 and 208

Answers

83620 the 2 is in the 10s place and on 208 the 2 is in the 100s place so the 2 in 208 is 10 times bigger than the 2 in 83620 I hope i'm right sorry if your not

Final answer:

The value of the digit 2 in both 83,628 and 208 is 200 because it is in the hundreds place in both numbers. The comparison shows that the absolute value of the digit 2 is the same in both cases despite being part of different overall numbers.

Explanation:

The value of the digit 2 in the numbers 83,628 and 208 represents different values because of its position in each number, which is determined by the place value system. In the number 83,628, the digit 2 is in the hundreds place, which means it represents 200. In the number 208, the 2 is in the hundreds place as well, so it also represents 200.

However, to understand the value of the 2 in comparison between the two numbers, you must consider the whole numbers. While the value of 2 as an individual digit is the same in both cases (200), the overall values of the numbers are different. In a more complex mathematical context, when comparing values within different numbers like this, the absolute value of the digits may be the same, but their contributions to the numbers they are part of can vary based on the other digits in the number.

Nonetheless, in this comparison, the two-digit 2s both contribute the same absolute value of 200 to their respective numbers because they are both in the hundreds place.

In quadrilateral ABDC, AB ∥ CD. Which additional piece of information is needed to determine that ABDC is a parallelogram?

AB ≅ CD
AC ≅ BD
AB ⊥ BD
CD ⊥ BD

Answers

The answer is B AC ≅ BD Since you already know that ab ll cd, all you need to know is that ac is bd

Answer:

B. AC ≅ BD

Step-by-step explanation:

Since the definition of a parallelogram literally says that it's a quadrilateral with 2 parallel sides, we have AB || CD so the 2 other sides (AC and BD) need to be either similar or parallel (either works, due to that if they're similar we can prove that since AB || CD that they're parallel).

If jimmy as three balls and gives away one and if earl gives jimmy fifteen balls and jimmy loses seven. how many balls does he have?

Answers

I believe the answer is 10,
3-1=2+15=17-7=10

Answer: Jimmy has 10 balls .

Step-by-step explanation:

Since we have given that

Number of balls Jimmy has = 3

Number of lost balls = 1

Remaining balls Jimmy has = 3-1=2

Number of balls Earl gives to Jimmy = 15

Now,

Total Number of balls Jimmy has = 15+2=17

Again,

Number of balls Jimmy lost = 7

So,

Remaining balls Jimmy has = 17-7=10

So, he has 10 balls at last .

What are the coordinates of the centroid of a triangle with vertices X(−4, 0) , Y(−1, 4) , and Z(2, 2) ? Enter your answer in the boxes.

Answers

[tex]distance \: xy \: = \sqrt{( { (3)}^{2} + {(4)}^{2} ) } \\ = \sqrt{(9 + 16)} = \sqrt{25} = 5[/tex]
[tex]distance \: xz \: = \sqrt{( {(2)}^{2} + {(6)}^{2} ) } \\ = \sqrt{(4 + 36)} = \sqrt{40} \\ = \sqrt{4} \times \sqrt{10} = 2 \sqrt{10} [/tex]

The centroid of a triangle is the point where the medians of the triangle meets.

The coordinates of the centroid is (-1,2)

The coordinates of the triangle are given as:

[tex]X = (-4,0)[/tex]

[tex]Y = (-1,4)[/tex]

[tex]Z = (2,2)[/tex]

The coordinates of the centroid is:

[tex]C = \frac 13(x_1 + x_2 + x_3,y_1+y_2+y_3)[/tex]

So, we have:

[tex]C = \frac 13(-4-1 + 2,0+4+2)[/tex]

[tex]C = \frac 13(-3,6)[/tex]

Expand

[tex]C = (\frac 13\times -3,\frac 13\times 6)[/tex]

[tex]C = (-1,2)[/tex]

Hence, the coordinates of the centroid is (-1,2)
