The standard form of the linear equation 15( y - 1/3 ) = x is 3x - 45y = -15.
What is the given equation in standard form?The standard form of a linear equation is expressed as;
Ax + By = C
Where A and B are the coefficient of x and y respectively, C is the constant term.
Given the equation in the question;
15( y - 1/3 ) = x
Multiply both sides by 3
3(15( y - 1/3 )) = 3x
First, apply distributive property to remove the parenthesis.
15( 3y - 1 ) = 3x
45y - 15 = 3x
3x = 45y - 15
Now, move all terms containing variables to the left and side of the equation and reorder the equation in form of Ax + By = C
3x - 45y = -15
Therefore, the standard form of the equation is 3x - 45y = -15.

A={1,2,3,4,5} and B={6,7,8,9}. Find A∪B
Answer:
{1, 2, 3, 4, 5, 6, 7, 8, 9}
Step-by-step explanation:
[tex]A \cup B[/tex] represents the set of all elements in [tex]A[/tex] or [tex]B[/tex].
B.__ angles form a straight line.
Complete the sentences
A. All right angles are 90 degrees (by definition)
B. supplemenatry angles form straight line (by definition)
C. If two angles form a linear pair, then the are supplementary (by definition)
D. When two lines intersect, the inverse angles are congruent.
In the given image of two intersecting lines, you have m∠1 = 67°
E. angle 2 and angle 1 are supplementary, then;
m∠2 + m∠1 = 180°
m∠2 = 180° - m∠1
m∠2 = 180° - 67°
m∠2 = 113°
F. angle 3 and angle 1 are congruent, then:
m∠3 = m∠1 = 67°
Due to the given image, you have the following expressions:
2x + x + 60° = 180° supplementary angles
3x + 60° = 180° subtract 60 both sides
3x = 180° - 60°
3x = 120° divide both sides by 3
x = 120/3
x = 40°
Furthermore, for y, you have:
x + y + y + 20° = 180° supplementary angles
x + 2y + 20° = 180° replace x = 40
40 + 2y + 20° = 180°
2y + 60° = 180° subtract 60 both sides
2y = 180° - 60°
2y = 120°
y = 120/2 divide by 2 both sides
y = 60°
Answer: 180 degree's make up a straight line.

Find the y-intercept.
To find the y-intercept, plug x = 0
[tex]\begin{gathered} \text{y = x}^2\text{ + 2x - 35} \\ y=0^2\text{ + 2}\times0\text{ - 35} \\ y\text{ = -35} \\ y-\text{intercept is (0 , -35)} \end{gathered}[/tex]Step 3:
Find the vertex
[tex]\begin{gathered} \text{The vertex is (}\frac{-b}{2a}\text{ , y)} \\ b\text{ = 2, a = 1} \\ x\text{ = }\frac{-b}{2a} \\ x\text{ = }\frac{-2}{2\times1} \\ x\text{ = }\frac{-2}{2} \\ x\text{ = -1} \\ y=(-1)^2\text{ + 2(-1) - 35} \\ y\text{ = 1 - 2 - 35} \\ y\text{ = -36} \\ \text{Vertex = (-1, -36)} \end{gathered}[/tex]Final answer
All the five points are:
Roots (x-intercept) = (-7, 0) , (5 , 0)
y-intercept = (0, -35)
vertex = (-1, -36)
Other point = (-5, -20)

This hutch is made up of two rectangular prisms. 1 7 ft 2 ft 2 127 ft 22 ft 4 ft What is the total volume of this hutch, in cubic feet?
Answer
40 cubic feet
Step-by-step explanation
The volume of a rectangular prism is calculated as follows:
[tex]V=whl[/tex]where w is the width, h is the height and l is the length of the prism.
The hutch is made up of two rectangular prisms, one with a width of 1 1/3 ft, a height of 2 1/2 ft, and a length of 4 ft. The other one has a width of 2 2/3 ft, a height of 2 1/2 ft, and a length of 4 ft.
To calculate the volume of the hutch, first, we need to calculate the volume of each prism, and then add them.
The volume of the smaller prism is:
[tex]\begin{gathered} V_1=1\frac{1}{3}\cdot2\frac{1}{2}\cdot4 \\ V_1=13\frac{1}{3}\text{ cubic feet} \end{gathered}[/tex]The volume of the bigger prism is:

An industrial machine made 1,629 cans of diet sodas and 6 times as many
regular sodas over the course of 46 minutes. The regular sodas were then
placed into 3 shipping boxes with each shipping box containing the same
number of sodas. How many regular sodas were in each shipping box.
Each of the shipping boxes contains 2172 cans of regular soda.
Ratios and fractions are the main bases on which proportion is explained. Two ratios are equal when they are expressed as a fraction in the form of a/b, ratio a:b, and then a proportion.
The industrial machine made a total of 1629 cans of diet soda which is 6 times as much regular soda in 46 minutes.
Then, the total number of regular sodas made will be:
R = 4 × Total number of diet soda
R = 4 × 1629 cans
R = 6516 cans
The regular sodas were packed in 3 shipping boxes with each having the same number of soda cans.
Therefore, the number of cans of regular sodas in each box will be:
N = 6516/3
N = 2172 cans
There are 2172 cans of regular sodas in each shipping box.
