Hey do you need an explanation let me know if you doo!!!
Step-by-step explanation:
[tex] =\tt \frac{3}{7} m - 3 + 4n + \frac{2}{7} m - 2n + 6[/tex]
[tex] =\tt \frac{3}{7} m + \frac{2}{7} m + 4n - 2n + 6 - 3[/tex]

PLEASE HELP ME SOLVE THIS Find all x-values for which f ( x ) = 2 for the function below.
{ ( - 3, 2 ), ( - 1, 0 ), ( - 3, 1 ), ( 2, - 3 ) }
Answer:
x = -3Step-by-step explanation:
First let us get the equation of the coordinates
y-y0 = m(x-x0)
Using the coordinates ( - 3, 2 ), ( - 1, 0 )
m = 0-2/-1-(-3)
m = -2/2
m = -1
Substitute m = -1 and (-1, 0) into the formula
y - 0 = -1(x+1)
y = -x-1
f(x) = -x-1
Since f(x) = 2
2 = -x-1
-x = 2+1
-x = 3
x = -3
Hence the value of x is -3

What is the range of the function represented by the graph?
the graph of a quadratic function with a maximum value at the point (2,4) and zeros at 0 and 4
A. y ≥ 1
B. y ≤ 1
C. all real numbers
D. 1 ≤ y ≤ 6
plz i need help fast it a test
Answer:
A. y ≥ 1
Step-by-step explanation:
The range of the function of the graph of a quadratic function is all values of y which are greater than and equal to 1 option (A) is correct.
What is a quadratic function?Any function of the form [tex]\rm f(x) = ax^2+bx+c[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
We have shown in the graph a graph of a quadratic function.
As we can see, the domain of the function will be all real numbers because it is a polynomial function in the form of:
f(x) = ax² + bx + c
The graph opens up and does not exist in the third and fourth quadrant, so we can say the range of the function will be:
y ≥ 1
Thus, the range of the function of the graph of a quadratic function is all values of y which are greater than and equal to 1 option (A) is correct.

Help please I have to get on the regular one soon
Answer:
1. 2x + 8y = 10xy
2. 13ab + 15ab = 28ab
Step-by-step explanation:
This is because for question 2 the "a" and "b" stay together since it's on 13 and 15. So that is why you would get 28ab. For question 1 it's basicly the same but instead, you combine the two to get your answer.

Prove: An odd number cubed is an odd number. (2n + 1)^3 = [ ? ]n^3 + [ ? ]n^2 + [ ? ]n [ ? ](4n3 + 6n2 + 3n) + [ ? ] = an odd
An odd number cubed is an odd number.
To answer the question, we need to know what odd numbers are
What are odd numbers?Odd numbers include 1,3, 5,7... and take the general for (2n + 1) where n = 0, 1, 2...
Now, we need to show that an odd number cubed is an odd number.
So, the odd number (2n + 1) cubed is
(2n + 1)³ = (2n + 1)(2n + 1)²
= (2n + 1)(4n² + 4n + 1)
= 8n³ + 8n² + 2n + 4n² + 4n + 1
= 8n³ + 12n² + 6n + 1
= 2(4n³ + 6n² + 3n) + 1
Since (4n³ + 6n² + 3n) is an integer say k, we have that
2(4n³ + 6n² + 3n) + 1 = 2k + 1
Since 2k + 1 is an odd number, 2n + 1 is an odd number and (2n + 1)³ = 2k + 1 which is an odd number.
So, an odd number cubed is an odd number.

the runner's time to complete the marathon is 45 minutes. The time to complete the last marathon was 49.5 minutes. What is the percent decrease of the time ?
Answer:
9.09%
Step-by-step explanation:
To find percent decrease you have to use this equation:
[tex]Percent Decrease = \frac{Initial -New}{Initial} x 100[/tex]
Initial = 49.5
New = 45
Plug in and solve:
[tex]PD = \frac{49.5-45}{49.5} x 100\\\\PD = \frac{4.5}{49.5} x 100 \\\\PD = 0.0909 x 100\\\\PD = 9.09[/tex]
The percent decrease is 9.09%

A sphere has a diameter of 12 ft. What is the volume of the sphere? Give the exact value in terms of Pi.
Formula of volume of a Sphere is : V = 4/3 πr³
Here, Diameter (2r) = 12, so radius (r) = 12/2 = 6 feet
Substitute it into the formula,
V = 4/3 π(6)³
V = 4/3 *216π
V = 288π Ft² [ Answer in the term of π ]
You can also solve it for numeral value by substituting the value of π = 22/7
V = 288 * 22/7 = 905.15 Ft² [ Answer in numbers ]
