Answer down below!
Step-by-step explanation:
Lets start off by finding a point we can start off at!
Since (2,0) lands perfectly on the number line, we can use that one!
From there, use the rise/run method to find your slope
We go up 2 and over -2
Thus our fraction is -2/2 BUT WE AREN'T DONE!
We can simplify this to be -1/1 or -1
Thus, our slope is -1
It's negative one, starting from the y intercept you're going down one right one and so on.

2. How tall is the actual book?
inches
The height will be 18 inches and the scale is 1 inch = 6 inches.
1.5 inches is the width of a book picture shown on a website.
And the book's length, as displayed on the website, is 3 inches
The book's real width is 9 inches.
The book image's size is

Find the equation of the line that is perpendicular to the line y =5x + 6 and passes through the point (-3,3). Write the equation in point slope form.
The point-slope form of equation of the line perpendicular to the line y = 5x + 6 nd passing through (-3,3) is x + 5y = 12.
If two lines are perpendicular to each other, then the product of slopes of these two lines is equal to -1.
The provided line is y = 5x + 6,
The slope M₁ of the line is equal to the coefficient of x,
M₁ = 5
Let the slope of the perpendicular line is M₂,
So, we can write,
M₁M₂ = -1
M₂ = -1/5.
Now, we can use the point slope form of the equation of line, according to which is if line passes through (a,b) and have slope m then the equation of the line will be,
(y-a) = m(x-a)
This form of line is called Point-slope form of line.
Then, the equation of the line with slope -1/5 and passing through (-3,3) will be,
(y-3) = -1/5(x+3)
-5y+15 = x+3
x + 5y = 12

What is Equation?Two or more expressions with an equal sign is called as Equation.
Given that,
A concession stand sells drinks and hotdogs.
The number of drinks sold is 5 more than 4 times the number of hotdogs sold.
The stand sold 500 items.
Let the number of hotdogs=x
The number of drinks sold is 5 more than 4 times the number of hotdogs sold.
The number of drinks=5+4x
stand sold 500 items.
Let us formulate a equation by given data
5+4x=500
Let us separate the variable x on one side.
Subtract 5 on both sides
5+4x-5=500-5
4x=500-5
4x=495
Divide both sides by 4

The answer to the given notation is 1970
What is standard notation ?Any value between 1.0 and 10.0 that can be expressed as a decimal number and multiplied by a power of 10 is referred to as being in standard form. If you look closely, you will see that 1.23 is a decimal between 1.0 and 10.0, and as a result, we have the standard form of 123,000,000 as 1.23 108.
This is already an standard notation : 1.97 × 10³
10 raised to the power three means there are three zeroes.

Solve negative a minus four sevenths equals two thirds for a.
a equals negative 26 over 21
a equals 26 over 21
a equals negative 2 over 21
a equals 2 over 21
The solution for the linear equation is a = -26/21, so the correct option is the first one counting from the top.
How to solve the linear equation?Here we have a mathematical statement that can be written as the following linear equation:
-a - 4/7= 2/3
To solve this for a, we just need to isolate a in one of the sides of the equation, so let's do taht.
-a - 4/7 = 2/3
a = -4/7 - 2/3
Now we need a common denominator in the right side, i will use 21.
a = -12/21 - 14/21 = -26/21
So the correct option is the first one.

b. AAA ran tests on fuel efficiency and found the 2004 Toyota Corolla actually got 28.9 miles per gallon driving around town. Using AAA's estimate, how long could you drive before running out of gas? Round according the guidelines.
c. How many miles less does the AAA estimate predict you can get on a single tank of gas? Round according the guidelines.
a) If the tank is full, using mathematical operations based on the 2004 Toyota Corolla, you will run 422.4 miles before running out of gas, according to Toyota's advert.
b) Using AAA's estimate, one could drive 381.4 miles before running out of gas.
c) Based on the AAA estimate, on a single tank of gas, you can predict that you will get 40.9 miles less.
What are mathematical operations?The mathematical operations include subtraction, addition, division, and multiplication.
For our purpose, we have used the mathematical operations of multiplication and subtraction to determine the above values.
Claimed mileage per gallon, according to the Toyota advert = 32 miles
The number of gallons of gas in Toyota Corolla's full tank = 13.2 gallons.
AA fuel efficiency on 2004 Toyota Corolla = 28.9 mpg
a) Miles to run before running out of gas (Toyota advert) = 422.4 (32 x 13.2) miles
b) Miles to run before running out of gas (AAA rating) = 381.48 (28.9 x 13.2) miles

Step-by-step explanation:
You want the ratio of volumes of spheres 428 inches and 4 inches in diameter.
VolumeThe volume of a sphere in terms of its diameter is ...
V = (π/6)d³
The ratio of the volumes of the larger to smaller sphere is ...
[tex]\dfrac{V_{large}}{V_{small}}=\dfrac{\pi/6\cdot428^3}{\pi/6\cdot4^3}=\left(\dfrac{428}{4}\right)^3=107^3=\boxed{1,\!225,\!043}[/tex]
The ratio of volumes is 1,225,043.
The ratio of the volume of the large sphere to the volume of the small sphere is 1225043:1
The following is the formula for finding the volume of a sphere:
V = [tex]\frac{4}{3} \pi r^3[/tex]
Now, the normal assumption is that we must use the formula to calculate the volume of both spheres in order to compare. However, observe that in comparing the volume of two different spheres, the only difference between them is the radius, thus we can compare the two spheres directly in this way:
