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 questions as mentioned.
Direct variation of {y} with {x} means that as {x} increases, the value of {y} increases uniformly with it. Mathematically -{K} = y/x = constant
Scale factor {K} is a dimensionless value that indicates the constant ratio value indicating direct variation.{ 1 } -
The variables y and x have a proportional relationship.Also y = 15 when x = 3.We can write for proportional relationship as : 15/3 = 4/x{x} = (4 x 3)/15 = 4/5
{x} = 4/5
{ 2 } -
The variables y and x have a proportional relationship.Also y = 9 when x = 2.We can write for proportional relationship as : 9/2 = y/3{y} = (9 x 3)/2 = 27/2 = 13.5
{y} = 13.5
{ 3 } -
An equation representing a proportional relationship is of the form -
y = mx + c
So all the equations given represent proportional relationship.
Therefore, the answers to each part is mentioned above.

What is the product of the rational expressions shown below? Make sure your
answer is in reduced form.
Answer:
Option (D)
Step-by-step explanation:
Product of the given rational expressions is,
[tex]\frac{x+1}{x-4}\times \frac{5x}{(x+1)}[/tex]
Further solve the given expression,
[tex]\frac{x+1}{x-4}\times \frac{5x}{(x+1)}[/tex] = [tex]\frac{5x(x+1)}{(x+1)(x-4)}[/tex]
Now we can cancel the common terms from numerator and denominator.
Common term → (x + 1)
Therefore, solution of the rational expression will be,
[tex]\frac{5x}{x-4}[/tex]
Option (D) will be the correct option.

-3 1/6 divide by (-2 1/3)
Answer:
1 5/14
Step-by-step explanation:
-3 1/6 / -2 1/3
-3 1/6 = -19/6
-2 1/3 = -7/3
-19/6 / -7/3 = -19/6 x -3/7
-19 x -3 = 57

What percent of 153 is 9.18? Show your work as well please
Answer:
6% of 153 is 9.18 and thats the answer
Answer:
9.18 is 6% of 153
Step-by-step explanation:
p/100 x 153 = 9.18
100/153 x p/100 x 153 = 100/153 x 9.18
100/153 x p/100 x 153 = 918/153
p=6
Write in slope intercept form of the equation of the line parallel to y= -2x + 5 and that passes through the point (3,1)
Answer:
y = -2x + 7
Step-by-step explanation:
In a equation thats parallel to y = -2x + 5, we have the same slope but different y intercepts (b).
SO we plug in point (3, 1) into y = mx + b
y = -2x + b
1 = -2(3) + b
1 + 6 = b
b = 7
So just plug in b back into the equation
y = mx + b
y = -2x + 7
Answer:
Step-by-step explanation:
y= -2x + 7
using point-slope formula:
y - y1 = m(x - x1)
Substitute:
y - 1 = m(x - 3)
Now, what is m and how do we find it?
m represents the slope. To find the slope in this circumstance, we have to look at the equation that we were given in the problem.
y= -2x + 5
Since we are trying to find a line parallel to this equation, we will be using the same slope that this uses.
The slope in the equation is -2.
Let’s substitute -2 for m.
y - 1 = -2(x - 3)
Now distribute:
y - 1 = -2x +6
Add 1 to both sides:
y = -2x + 7
Now we have an equation in slope-intercept form that is parallel to y= -2x + 5 and runs through the point (3, 1).

Answer:
2sqrt(14)*i
Step-by-step explanation:
(sqrt(-56))
since theres a negative in it we know there will be an i in the answer.
We need to find two numbers that multiple to 56 with at least one of them being a perfect sqaure
7*8 doesn't work
4*14 = 56
ok sqrt(4) = 2
can't take the sqaure of (14)
so we are left with
2sqrt(14)*i <---remember from before?

A grocery store was having a sale. Darla had $15 in her wallet. She planned to purchase 2 gallons of fruit juice, 3 bags of chips, and a box of cupcakes. Item Sale Price Gallon of fruit juice $3.50 for first gallon, 50% off the second gallon Bag of Chips 2 for $5 or $2.65 each Box of cupcakes $4.79 How much would Darla pay for her groceries before tax? Show your work.
Answer:
The amount Daria would pay for the groceries is $17.69
Step-by-step explanation:
The amount Daria had in her wallet = $15.00
The quantity of fruit juice she planned to purchase = 2 gallons
The number of bags of chips she planned to purchase = 3 bags
The number of boxes of cupcakes she planned to buy = One box
The price for the first gallon of fruit juice = $3.50
The price for the second gallon of fruit juice = 50% off the sale price
The price of 2 bags of chips = $5
The price per bag of chips = $2.65
The price of each box of cupcakes = $4.79
Therefore;
The amount Daria would pay for the groceries = 3.50 + 0.5×3.50 + 5 + 2.65 + 4.79 = 17.69
The amount Daria would pay for the groceries = $17.69.

Answer:
-101 feet
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relevant relation is ...
Tan = Opposite/Adjacent
Opposite = Adjacent × Tan
height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft
__
The usual relation between estimates and errors is ...
error = estimate - actual
Then ...
actual = estimate - error
For the given angle and error, the actual angle is ...
actual angle = 47° -(-1°) = 48°
actual height = (2640 ft)·tan(48°) ≈ 2932 ft
Then the change in the height of the mountain due to the error is ...
2831 ft -2932 ft = -101 ft
The error of -1° in angle estimate creates an error of -101 ft in the height estimate.
