Answer:
They are the same line written in different forms.
Step-by-step explanation:
Given a linear function with a slope of [tex]-\frac{7}{9}[/tex] and a y-intercept of 3.
The equation of the line in the slope-intercept form is given as:
[tex]y=-\frac{7}{9}x+3[/tex]
Given the other line,
[tex]y+11=-\frac{7}{9}(x-18)[/tex]
Simplified:
[tex]y+11=-\frac{7}{9}x+14\\y=-\frac{7}{9}x+14-11\\y=-\frac{7}{9}x+3[/tex]
The two lines are one and the same line.
Answer:

Your Answer Is (A) 2x^3-8x-10
plz mark me as brainliest :)
Answer:
A
Step-by-step explanation:
Let's first expand these parentheses. Remember that when we have a negative sign in front of a parentheses, that means we're multiplying each term within the parentheses by -1:
2x - 10 -3x^2 - 10x + 2x^3 + 3x^2
Now combine like terms. Like terms are the ones that have the same degree of x: 2x and -10x are like terms; -10 is by itself; -3x^2 and 3x^2 are like terms; 2x^3 is by itself. So:
2x^3 + (-3x^2 + 3x^2) + (2x - 10x) - 10
2x^3 - 8x - 10
Thus, the answer is A.

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say that number is x
Given,
Half of a number is 16
So,
x/2 = 16
By multiplying 2 both sides

The bathysphere was an early version of a submarine, invented in the 1930s. The inside
diameter of the bathysphere was 56 inches, and the steel used to make the sphere was 1.5
inches thick. It had three 10-inch diameter windows. Estimate the volume of steel used to
make the bathysphere to the nearest whole number.
It took about
in.of steel to make the bathysphere.
The volume of steel used to make the bathysphere is approximately 53,481 cubic inches.
Explanation:To estimate the volume of steel used to make the bathysphere, we need to calculate the volume of the sphere and subtract the volume of the windows. The volume of the sphere can be calculated using the formula for the volume of a sphere: V = (4/3)πr³, where r is the radius of the sphere. Since the diameter of the bathysphere is 56 inches, the radius is half of that, which is 28 inches. Converting to meters, the radius is approximately 0.7112 meters.
Now we can calculate the volume of the sphere: V = (4/3)π(0.7112)³ ≈ 0.8827 cubic meters.
The volume of each window can be calculated using the formula for the volume of a cylinder: V = πr²h, where r is the radius of the window and h is the height of the window. The radius of each window is half of the diameter, which is 5 inches or approximately 0.127 meters. The height of each window is 1.5 inches or approximately 0.0381 meters.
Now we can calculate the volume of each window: V = π(0.127)²(0.0381) ≈ 0.0024 cubic meters.
Since there are three windows, the total volume of the windows is 3 × 0.0024 ≈ 0.0073 cubic meters.
To estimate the volume of steel used to make the bathysphere, we subtract the volume of the windows from the volume of the sphere: approximately 0.8827 - 0.0073 ≈ 0.8754 cubic meters.
Finally, we convert the volume to cubic inches to estimate the amount of steel used: 0.8754 × 61023.7 ≈ 53481 cubic inches. Rounding to the nearest whole number, the volume of steel used to make the bathysphere is approximately 53,481 cubic inches.

A number, rounded to 2 decimal places, is equal to 45.55.
Write down the lower and upper bounds of the number,
Lower bound =
Upper bound
Final answer:
The lower bound of the number rounded to 2 decimal places is 45.54, and the upper bound is 45.56.
Explanation:
To find the lower and upper bounds of a number when it is rounded to 2 decimal places, we need to consider the two possible values that round down and round up from the given number.
In this case, the number is 45.55.
The lower bound is the number rounded down.
When we round down 45.55 to 2 decimal places, we get 45.54.
The upper bound is the number rounded up.
When we round up 45.55 to 2 decimal places, we get 45.56.

1. The distance in kilometers to Proxima Centauri, the closest star to the Earth, is
39,900,000,000,000. Write this in scientific notation.
The equation for the distance in kilometers to Proxima Centauri is
D = 3.99 x 10¹³
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The total distance from Earth to the closest star Proxima Centauri be = D
Now , the value of distance D = 39,900,000,000,000
Now , the equation to find the scientific notation is done by calculating the number of zeros in the equation
So , The distance D has 11 zeros in it
So , the distance D can be written as powers of 10 in the form
Distance D = 399 x 10¹¹
Now , 399 can be written as 3.99 x 10²
So , the equation can be simplified as
Distance D = 3.99 x 10² x 10¹¹
Distance D = 3.99 x 10¹¹⁺²
Distance D = 3.99 x 10¹³
Therefore , the value of D is 3.99 x 10¹³
Hence , The distance in kilometers to Proxima Centauri is 3.99 x 10¹³

The perimeter of a square is represented by the expression 32x - 12.8. Draw a square to represent this situation and label its side lengths. Then write three equivalent expressions for the perimeter.
Answer:
Step-by-step explanation:
Given that: The perimeter of a square is: 32x - 12.8
As we all know that, the formula to find the perimeter of a square is:
Sum of the 4 side = 4* length of the side
=> the length of 1 side: The perimeter of a square / 4
In this situation, we have length of 1 side side is:
(32x - 12.8) / 4
= 32/4x - 12.8/4
= 8x - 3.2
The 1st equivalent expressions for the perimeter: 4 *(8x - 3.2)
The 2nd equivalent expressions for the perimeter: (8x - 3.2) + (8x - 3.2) + (8x - 3.2) + (8x - 3.2)
The 3rd equivalent expressions for the perimeter: 2*(8x - 3.2) + 2*(8x - 3.2)
