If the equation for the regression line is y=-8x+3 then the slope of this line is
Answers
The slope of the given linear function y = -8x + 3 will be -8.
What is a linear function?
A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given line,
y = -8x + 3
The slope-intercept form is given as y = mx + c
By comparing,
m = -8
Hence "The provided linear function, y = -8x + 3, will have a slope of 8".

So this equation is already in y=mx+b, therefore the slope is -8.
If you are still ocnfused google slpoe-intercept form

What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality relation be A
And the equation is 3x - 2 ≤ 2x + 1.
So , on simplifying the equation , we get
3x - 2 ≤ 2x + 1.
Subtracting 2x on both sides of the inequality equation , we get
x - 2 ≤ 1
Adding 2 on both sides of the inequality equation , we get
x ≤ 3
Therefore , the value of x satisfies all the numbers that are less than or equal to 3
Hence , The solution set is {x | x R, x ≤ 3}

Answer:
Option 3 and 5 are correct
Step-by-step explanation:
We have given a geometric series 640,160,40,10....
Common ratio of geometric series is
Here our common ratio is less than zero
It will show the graph of exponential decay
Hence, option 5 is correct.
The general term of geometric series is
Domain will be all natural numbers since, geometric series take only natural numbers.
Here, values of "n" is domain
Hence, option 3 is correct.
Range can be any positive real numbers not only natural number
Range is the value of
Hence, option 4 is discarded.
Graph can not be linear of a geometric series being exponential
Hence, option 2 is discarded.
Option 1 is discarded because it is exponential decay function so it can not be exponential growth.
Therefore, Option 3 and 5 are correct.
Answer:
The options that hold true are:
- The domain will be the set of natural numbers.
- The graph will show exponential decay.
Step-by-step explanation:
We are given a geometric sequence as:
640, 160, 40, 10, ...
Clearly we see that each term is decreasing at a constant rate as compared to it's preceding term.
Hence, the graph formed by this sequence will be a exponential graph with decay .
( since, the terms of the sequence are decreasing)
The sequence could be modeled as:
Let represents the nth term of the sequence.
Hence,
As, the sequence is geometric hence the domain will be a set of natural numbers.
but the range will be positive real numbers.
Hence, the correct option is:
The domain will be the set of natural numbers.
The graph will show exponential decay

Yes
Step-by-step explanation:
10:12 and 30:36
you can simplify them first so
10:12=5:6
and
30:36=5:6 which is equivalent to the other ratio
or you can do
