Write the equation of the line passing through the points (15,4) and (-3,-3) please helppp 10 points pleaseeeeeeeeeee
Answers
Answer: [tex]y = \frac{1}{3}x-2[/tex]
This is the same as writing y = (1/3)x - 2
Slope = 1/3
y intercept = -2
======================================================
Explanation:
We first need to determine the slope
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-3-3}{-3-15}\\\\m = \frac{-6}{-18}\\\\m = \frac{1}{3}\\\\[/tex]
Then we'll use this value of m, along with (x,y) = (15,3), to determine the y intercept b value.
[tex]y = mx+b\\\\3 = (1/3)(15)+b\\\\3 = 5+b\\\\3 - 5 = b\\\\-2 = b\\\\b = -2[/tex]
You could use the other point (-3,-3) as well
[tex]y = mx+b\\\\-3 = (1/3)(-3)+b\\\\-3 = -1+b\\\\-3 +1 = b\\\\-2 = b\\\\b = -2[/tex]
Either way, we end up with the same y intercept. You don't need to show both sets of steps when computing b. You only need to pick one set of steps.
Since m = 1/3 and b = -2, we go from y = mx+b to y = (1/3)x - 2 which is the same as writing [tex]y = \frac{1}{3}x-2[/tex]
Answer:
y = 7/18 - 11/6
Step-by-step explanation:
y2 - y1 / x2 - x1
-3 - 4 / -3 - 15
-7/-18
= 7/18
y = 7/18x + b
4 = 7/18(15) + b
4 = 35/6 + b
-11/6 = b

Graph the equation,
y = 5x - 5
Answers
Answer:
Step-by-step explanation:
there are 2 ways to graph equations. I'll teach u the faster way.
step 1) graph the y-intercept.
so the slop-intercept form of a line is y=mx+b. b represents the y-intercept and m represents the slope. u need two points to graph a line, the first point will be the y intercept. in this case, the y-intercept is -5. so this is what you should do: (the underlined star represents a point. also, the underlined star is on point -5.)
| y
|
|
|
------------------------------------------------------------x
|
|
|
|
*

step 2) graph the second point using the slope.
slope equals rise over run. (m=rise/run.) in this case, the slope is 5/1. To graph the second point, u should RISE up by 5 and RUN to the right by one: (the underlined star is on point 1.)
| y

Consider the functions f(x) = 6x - 5 and g(x) = 6x + 3. Which statement compares the
relationship between the graphs of the two functions?
A) The graph of g(x) is the same as the graph of f(x) translated down 2 units.
B) The graph of g(x) is the same as the graph of f(x) translated up 8 units.
C) The graph of g(x) is the same as the graph of f(x) translated up 2 units.
D) The graph of g(x) is the same as the graph of f(x) translated down 8 units.
Answers
Answer:
D
Step-by-step explanation:
since we have -5 and 3, in order to translate f(g) into f(x), we subtract 8 from f(g)
The graph of g(x) is the same as the graph of f(x) translated up 8 units. Therefore, option B is the correct answer.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Given that, f(x)= 6x-5 and g(x)= 6x+3.
When the shape is moved up by k units, then replace y with y + k.
Here, g(x)=6x-5+8
g(x)= 6x+3
The graph of g(x) is the same as the graph of f(x) translated up 8 units. Therefore, option B is the correct answer.

The process of isolating the variable is the primary step involved in solving an equation.
Thus, option (B) is correct.
A) Substitution refers to the act of replacing a variable with a known value in an equation, which can be a useful strategy in some cases but is not a fundamental step in solving equations.
B) To solve an equation, it is necessary to perform operations that isolate the variable on one side of the equation and keep the other side free of the variable.
C)To verify if the obtained solution satisfies the original equation, but it is not a step required to solve the equation.

The total amount of candy sold at Cassandra's Candy Corner can be represented by the function C(x) = 4x3 + 10x2 + 54x + 520, where x represents the number of years since the store opened. The amount of types of candy can be modeled by the linear function T(x) = 2x + 10. Which expression represents the amount of candy sold each year per type at Cassandra's Candy Corner?
2x^2 – 5x + 52
2x^2 + 5x + 52
4x^3 + 10x^2 + 52x + 510
4x^3 + 10x^2 + 56x + 530
Answers
Using polynomial division, it is found that the expression that represents the amount of candy sold each year per type at Cassandra's Candy Corner is:
[tex]2x^2 - 5x + 52[/tex]
The amount of candy sold per type is given by the following division:
[tex]\frac{C(x)}{T(x)} = \frac{4x^3 + 10x^2 + 54x + 520}{2x + 10}[/tex]
The denominator can be written as:
[tex]2x + 10 = 2(x + 5)[/tex]
At the numerator, to see if we can simplify, we verify if x = -5 is a factor:
[tex]C(-5) = 4(-5)^3 + 10(-5)^2 + 54(-5) + 520 = 0[/tex]
Since C(-5) = 0, it is a factor of the numerator, and thus, since the numerator is of the 3rd degree, it can be written as a 3 - 1 = 2nd degree polynomial multiplying x + 5:
[tex](ax^2 + bx + c)(x + 5) = 4x^3 + 10x^2 + 54x + 520[/tex]
[tex]ax^3 + (5a + b)x^2 + (5b + c)x + 5c = 4x^3 + 10x^2 + 54x + 520[/tex]
Equaling both sides:
[tex]a = 4[/tex]
[tex]b = 10 - 5a = -10[/tex]
[tex]5c = 520 \rightarrow c = 104[/tex]
Thus:
[tex]C(x) = (4x^2 - 10x + 104)(x + 5)[/tex]
And:
[tex]\frac{C(x)}{T(x)} = \frac{(4x^2 - 10x + 104)(x + 5)}{2(x + 5)} = 2x^2 - 5x + 52[/tex]
Thus, the expression is:
[tex]2x^2 - 5x + 52[/tex]

What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

= 2 / 4
= 1/2
