What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given are the equations as -
x + y = 3
x² + y² = 17
Refer to the graph of the function attached. The points of intersection represents the possible solution set.

Researchers in plant growth are investigating the proportions of seedlings that sprout under two environmental settings in a lab experiment. Let pˆC represent the sample proportion of seedlings that sprout in garden C, and let pˆH represent the sample proportion of seedlings that sprout in garden H. For random samples of 100 garden C seedlings and 100 garden H seedlings, the sampling distribution of the difference between sample proportions pˆC−pˆH has σpˆC−pˆH≈0.051. Which of the following is the best interpretation of σPˆC−PˆH≈0.051 ?

The length of a rectangle is three times its width.
If the width is represented by x, what is the
perimeter of the rectangle, in terms of x?
Answers
Answer:
perimeter:- 8x
Step-by-step explanation:
since,
length= 3(width)
length= 3x
and, perimeter= 2(l + b)
= 2(3x + x)
= 2(4x)
perimeter = 8x

Type an equation of a parabola that is moved down 2 units, stretched vertically by a factor of 3, and moved left 5 units.
Answers
9514 1404 393
Answer:
y = 3x^2 +30x +69
Step-by-step explanation:
Transformations work this way:
g(x) = k·f(x) . . . . vertical stretch by a factor of k
g(x) = f(x -h) +k . . . . translation (right, up) by (h, k)
__
So, the translation down 2 units will make the function be ...
f(x) = x^2 ⇒ f1(x) = f(x) -2 = x^2 -2
The vertical stretch by a factor of 3 will make the function be ...
f1(x) = x^2 -2 ⇒ 3·f1(x) = f2(x) = 3(x^2 -2)
The horizontal translation left 5 units will make the function be ...
f2(x) = 3(x^2 -2) ⇒ f2(x +5) = f3(x) = 3((x +5)^2 -2)
The transformed function equation can be written ...
y = 3((x +5)^2 -2) = 3(x^2 +10x +25 -2)
y = 3x^2 +30x +69
__
The attachment shows the original function and the various transformations. Note that the final function is translated down 6 units from the original. That is because the down translation came before the vertical scaling.

Simplify the mathematical expressions and arrange them in order of their values from least to greatest. ↓ ↓ ↓ ↓
Answers
Answer and Step-by-step explanation:
To simplify algebraic expressions, follow the basic rules:
1. Remove brackets or parentheses by multiplying factors;
2. Use exponent rule to remove grouping, if terms have exponents;
3. Add or subtract like terms;
4. Combine constants;
In the expressions above, there only constants and scientific notations, i.e., exponents elevated on a base 10. So, to simplify, we multiply the numbers and add the exponents:
(4.27 x 10⁸)(9.2 x 10⁻⁵) = 39.28 x 10³
(6.96 x 10⁵)(8.43 x 10⁻²) = 58.67 x 10³
[tex]\frac{(7.25.10^{5})(9.36.10^{-7})}{(7.95.10^{-2})(4.13.10^{-3})}=[/tex] 2.07 x 10³
[tex]\frac{(8.32.10^{4})(9.67.10^{1})}{(7.56.10^{11})(5.79.10^{-8})}[/tex] = 1.84 x 10²
[tex]\frac{(1.89.10^{4})(5.92.10^{3})}{(2.74.10^{-2})(4.67.10^{2})}=[/tex] 0.875 x 10⁷
All the exponents are positive, which means, comma "moves" to the right.
The numbers arranged from least to greatest will be
1.84 x 10² < 2.07 x 10³ < 39.28 x 10³ < 58.67 x 10³ < 0.875 x 10⁷

Answers
Answer:
Chelsea spent more than $12.75
Step-by-step explanation:
To solve this problem we should understand the meaning of signs first.
sign (<) → less than
sign (>) → more than
sign (=) → equal to
sign (≤) → Not more than
sign (≥) → At least
If the statement is,
"Chelsea spent more than $12.75"
d > 12.75
Therefore, Chelsea spent more than $12.75 is the correct statement.

The means and mean absolute deviations of the amount of rain that fell each day in a local city, last week and this week, are shown below. Means and Mean Absolute Deviations of Rainfall Last Week and This Week Last Week This Week Mean 3.5 in. 2.7 in. Mean Absolute Deviation 1.2 in. 0.5 in. Which expression compares the difference of the two means to this week's mean absolute deviation?
Answers
Answer:
0.8 / 0.5
Step-by-step explanation:
Given :
Deviations of Rainfall :
______Last Week ____ This Week
Mean___ 3.5 in. ________2.7 in
MAD ___ 1.2 in _________ 0.5 in
Mean difference = 3.5 in - 2.7 in = 0.8 in
This week's mean absolute deviation = 0.5 in
Mean difference / this week's mean absolute deviation
= 0.8 / 0.5

We first calculate the front and back which are 2 congruent(equal) triangles. The 2 areas together is...
9*6/2*2=54
Now we want to calculate the 2 rectangles at the top right and top left of the shape they are also congruent(equal). The 2 areas together is...
7*5*2=70
The last part is the rectangle on the bottom with area...
9*5=45
Now we just need to add them all together...

Answer:
223cm
Step-by-step explanation:
First you want to figure out how many faces the 3D shape has.
This has 5 faces.
Then you find the area of each face.
The front face has an area of 54cm because the length is 6cm and the width is 9cm.
Area = Length x Width
The back face will always have the same area as the front.
54cm + 54cm = 108cm (Front and Back Face)
Now the right side and left side.
The width of the side is 5cm and length is 7cm.
7cm • 5cm = 35cm
Just like the front and back, the right and left side will have the same area.
35cm + 35cm = 70cm
Now the last part.
There is no top face since this is a 3D triangle and not a square and rectangle etc.
So, you don't add it two times like the others.
The bottom's width is 5cm and the length is 9cm
5cm • 9cm = 45cm
Now you add all of it up together to find the surface area.
108cm + 70cm + 45cm = 223cm

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently.
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
100 POINTS
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Answers
Answer:
Equations for each salesman:
A. p(s) = 65sB. p(s) = 40s + 300C. p(s) = 900When s = 0, s= 1, s = 10 each of the gets paid:
A. p(0) = 0, p(1) = 65, p(10) = 650B. p(0) = 300, p(1) = 340, p(10) = 700C. p(0) = p(1) = p(10) = 900The above numbers as ordered pairs:
A B C s = 0 | (0, 0) | (0, 300) | (0, 900)s = 1 | (1, 65) | (1, 340) | (1, 900)s = 10 | (10, 650) | (10, 700) | (10, 900)9. Which of these was an example of US industrial mobilization for war?
