The equivalent expression in standard form is 10x + 2y. The given expression is:- 5x - 2(x - 3y) + 1/2(14x - 8y). By using distributive law, we have written equivalent expressions in standard form.
Hence,
= 5x - 2(x - 3y) + 1/2(14x - 8y)
= 5x - 2x + 6y + 7x - 4y
= (5x - 2x + 7x) + (6y - 4y)
= 10x + 2y.
Now, the equivalent expression is 10x + 2y. We got this by combining like terms of the given expression.
As stated above, the given expression is :
5x - 2(x - 3y) + 1/2(14x - 8y)
To get the equivalent expression in standard form, we must first simplify the terms inside the brackets.
= 5x - 2(x - 3y)
= 5x - 2x + 6y
= 3x + 6y.
Then, we must distribute the term 1/2 into the bracket on the right :
1/2(14x - 8y) = 7x - 4y
Now, our given expression can be written as:
5x - 2(x - 3y) + 1/2(14x - 8y)
= 3x + 6y + 7x - 4y.
Now we must combine like terms :
3x + 7x = 10x, 6y - 4y = 2y.
So, our final equivalent expression is 10x + 2y.
Therefore, we got the equivalent expression in standard form by simplifying the terms inside the brackets, distributing the term 1/2 into the bracket on the right, and then combining the like terms. The equivalent expression in standard form is 10x + 2y.

What is the length of AB?
Answer: 6 units
Step-by-step explanation:
I know that in a triangle, there's two angles that have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units.
Answer:
AB = 38.64 m
Step-by-step explanation:
[tex] \cos \: 75 \degree = \frac{10}{x} \\ \\ x = \frac{10}{ \cos \: 75 \degree } \\ \\ x = 38.637033052 \\ \\ x \approx \: 38.64[/tex]

Answer:
1. 2x² - 8x - 7
2. x³+ x + 30
Step-by-step explanation:
[tex]2 {x}^{2} - 9x - 2 +x - 5[/tex]
[tex]2 {x}^{2} - 8x - 7[/tex]
2x² has no other like terms to add or substract with so it stays as is.
(-9x) + x = -8
(-2) - 5 = -7
or
(-2) - (-5) = 3
Watch out for the ones on top. I'm a bit confused about them but those ones are your possible options.
//

[tex] {x}^{3} + x + 30[/tex]
x³ stays as is and so does x.
27 + 3 = 30

HELP it is due tomorrow and I am super super stuck I have been doing this one for the last 2 days and did I make any progress? NOOOOOOOOOO I GIVE UP
Step-by-step explanation:
First thing you need to do is Slope - intercept form of the line going through point A and B.
Slope-intercept form: y = mx + b (m = slope, b = y-intercept)
To get slope: [tex]\frac{y2 - y1}{x2-x1}[/tex]
Lets set point A as point1 (x1, y1) and point B as point2(x2, y2).
x1 = -4
x2 = 8
y1 = 6
y2 = 3
If you plug these numbers in the slope equations:
[tex]\frac{3 - 6}{8 - 4}[/tex] = [tex]\frac{-3}{4}[/tex]
m = [tex]\frac{-3}{4}[/tex]
So a parallel line is a line that has a different b value but the same slope value.
To get b for the parallel line : we need to substitute the x and y for a given point (0,-2).
which will make -2 = 0([tex]\frac{-3}{4}[/tex] ) + b
now we solve for b:
-2 = 0 +b
b = -2
So the whole Slope-intercept form of the parallel line is: y = [tex]\frac{-3}{4}[/tex] x -2

A rectangular path 60m and 3m is covered with square tiles of 25 cm. How many tiles wil be used to cover the path ?
Answer:
2880 tiles
Step-by-step explanation:
A rectangular path has dimensions 60 m and 3 m.
Area of a rectangular path = length × breadth = 60 × 3 = 180 [tex]m^2[/tex]
Use [tex]1\,m^2=10000\,cm^2[/tex]
So,
Area of a rectangular path = 180(10000) = 18,00,000 [tex]cm^2[/tex]
Side of a square tile = 25 cm
Area of a square tile = side × side = 25(25) = 625 [tex]cm^2[/tex]
Number of square tiles = Area of a rectangular path ÷ Area of a square tile
= [tex]\frac{1800000}{625} =2880[/tex] tiles

The students will paint 4 rooms on the first floor and the conference room on the second floor. Each room on the first-floor room is 4m x 5m.
1. Calculate the area of one of the rooms.
Answer:
20m
Step-by-step explanation:
The rooms are 4m x 5m.
To find the area, multiply length by width: 4*5=20
The Area of one room is 20 m².
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
Given:
First, Area of one room= lw
= 4 x 5
= 20 m²
Now, Area of four room = 4 x 20
= 80 m²
Thus, area of one room is 20 m².

Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Answer:
x = - 3, y = - 11
Step-by-step explanation:
Given the 2 equations
y = 7x + 10 → (1)
y = - 4x - 23 → (2)
Substitute y = 7x + 10 into (2)
7x + 10 = - 4x - 23 ( add 4x to both sides )
11x + 10 = - 23 ( subtract 10 from both sides )
11x = - 33 ( divide both sides by 11 )
x = - 3
Substitute x = - 3 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 7(- 3) + 10 = - 21 + 10 = - 11

The number of branches of an oak tree and a birch tree since 1950 are represented by the following tables:
Determine whether the data described in the tables is best modeled by a linear function or an exponential function
Answer:
oak tree is a linear function and birch tree is exponential
Step-by-step explanation:
cuz i just did it
The oak tree have a liner function and the birch tree have exponential function .
What is linear function?Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
What is exponential function?An exponential function is a mathematical function of the following form:
f ( x ) = [tex]a^{x}[/tex]. where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.
According to the question
The number of branches of an oak tree and a birch tree since 1950 are represented by the following tables:
Number of Oak trees (x) Number of branches f(x)
0 34
3 46
6 59
9 70
12 82
So in this table we can see that there is increment in number of branches but in a pattern approx.
i.e
f(x) = 34 + 4(x)
where x will be Number of Oak trees
therefore it is a Linear function
Number of Birch trees (x) Number of branches f(x)
0 8
10 33
20 128
30 512
40 2049
So , in this table is increasing in a very fast pace but in a pattern approx.
i.e
f(x) = [tex]8*4^{\frac{x}{10} }[/tex]
Therefore it is an exponential function
Hence, The oak tree have a liner function and the birch tree have exponential function .

Jayla and Brian are both selling cookie dough for a fundraiser. Although, Jayla has already sold 4 tubs, brian haven’t sold any yet. If jayla starts selling 1 Tun per day and brian begins selling 2 tubs per days, they will eventually sell the same amount of cookie dough, how many days will that take?
Write the expression. And solutions written as an ordered pair.
Answer:
cookie dough fundraiser is a great way to raise money for your school, team, ... selling large or small cookie dough tubs, or pre-portioned cookie dough trays.
Answer:
4 days
Step-by-step explanation:
If we say d = number of days passed, j = tubs sold by jayla and b = tubs sold by brian
j = 4 + d
because when d = 0 j must equal 4, then it goes up by 1 each day
b = 2d
because when d = 0 b must be 0, then it goes up by 2 each day
set them to be equal and solve for d
4 + d = 2d
d = 4
so after 4 days they sell the same amount which is 8
