Answer:
y + 5 = -3(x + 8)
General Formulas and Concepts:
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate
y₁ - y coordinate
m - slope
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Parallel Lines always have the same slope but different y-intercepts.
Step-by-step explanation:
Step 1: Define
Given (Parallel Line): y = -3x + 9
Point (-8, -5)
Step 2: Find variables
Slope m of parallel lines = -3
Step 3: Find parallel line equation
y₁ = -5
x₁ = -8
m = -3
y + 5 = -3(x + 8)
What is the domain of the given function?
A quadratic function has a line of symmetry at x = –3.5 and a zero at –9. What is the distance from the given zero to the line of symmetry? What is the other zero of the quadratic function?
Given:
A quadratic function has a line of symmetry at x = –3.5 and a zero at –9.
To find:
The other zero.
Solution:
We know that, the line of symmetry divides the graph of quadratic function in two congruent parts. So, both zeroes are equidistant from the line of symmetry.
It means, line of symmetry passes through the mid point of both zeroes.
Let the other zero be x.
[tex]-3.5=\dfrac{(-9)+x}{2}[/tex]
Multiply both sides by 2.
[tex]-7=-9+x[/tex]
Add 9 on both sides.
[tex]-7+9=-9+x+9[/tex]
[tex]2=x[/tex]
Therefore, the other zero of the quadratic function is 2.
Answer: A=0, B=6, C=4.
The axis of symmetry is x = ½
The smaller zero is -2
The larger zero is 3

m-18=n
This makes no sense this is my 3rd time asking this question
Answer:
m=18+n
Step-by-step explanation:
m + -18 = n simplify
-18 + m = n record the terms
-18 + 18 + m = 18 + n solve
Combine like terms: -18 + 18 = 0, 0 + m = 18 + n, m = 18 + n
Final answer: m = 18 + n
Answer:
IDK but here's what I have found.....
Step-by-step explanation:
Simplifying
m + -18 = n
Reorder the terms:
-18 + m = n
Solving
-18 + m = n
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + m = 18 + n
Combine like terms: -18 + 18 = 0
0 + m = 18 + n
m = 18 + n
Simplifying
m = 18 + n
Tommy is purchasing items from an online store. The store charges $6 shipping and handling for each package. Write an expression to represent the total shipping costs. How much will Tommy pay in shipping and handling for 2 packages? (use x as the variable) When entering your answers use only numbers a lower case x and No spaces The equation that represents this scenario is The shipping and handling for 2 packages would be dollars. (only put the number please)
Answer:
The expression to represent the total shipping costs for x package is 6x.
Tommy will pay $ 12 in shipping and handling for 2 packages.
Step-by-step explanation:
Given that the shipping and handling charge for 1 package = $ 6
So, by using the elementary method, the shipping and handling charge for x package is $ 6x.
Hence, the required expression to represent the total shipping costs for x package is 6x.
For 2 package, x=2
So, the shipping and handling charge for 2 package
=6x2
=12.
So, Tommy will pay $ 12 in shipping and handling for 2 packages.

Lainey read 15,700 words of her book on her family's road trip to the beach. Write the number of words that she read in scientific nototion.
Answer: 1.57 x 104
Step-by-step explanation: How to Convert a Number to Scientific Notation
The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.
Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.
Count how many places you moved the decimal point. This number is b.
If you moved the decimal to the left b is positive.
If you moved the decimal to the right b is negative.
If you did not need to move the decimal b = 0.
Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."
Remove trailing 0's only if they were originally to the left of the decimal point.

value
Answer:
(21.9, 66.3)
Step-by-step explanation:
Given the coordinates A (25.5, 60.1) and C (18.3, 72.5)
The formula for calculating the midpoint is expressed as;
M = {(x1+y1)/2, (y2+y1)/2}
X = (x1+y1)/2
Y = (y2+y1)/2
From the given coordinates A (25.5, 60.1) and C (18.3, 72.5)
x1 = 25.5, y1= 60.1, x2 = 18.3 and y2 = 72.5
X = (25.5+18.3)/2
X = 43.8/2
X = 21.9
Y = (72.5+60.1)/2
Y = 132.6/2
Y = 66.3
The midpoint of the coordinates M will be M(21.9, 66.3)
1.2x+4.3=2.1-x
Please help!!!
Answer:
x=1
Step-by-step explanation:
subract 4.3 from both sides. add x to both sides. divide by 2.2 from both sides
The solution to the equation 1.2x + 4.3 = 2.1 - x is x = -1.
Given is an equation 1.2x + 4.3 = 2.1 - x, we need to solve for x,
To solve the equation 1.2x + 4.3 = 2.1 - x, we can follow these steps:
1. Combine like terms on both sides of the equation:
1.2x + x = 2.1 - 4.3
2. Simplify the equation:
2.2x = -2.2
3. Divide both sides of the equation by 2.2 to isolate x:
x = -2.2 / 2.2
4. Simplify the right side of the equation:
x = -1
Therefore, the solution to the equation 1.2x + 4.3 = 2.1 - x is x = -1.
