Station 2: Unit 3 and Unit Linear Functions given the table x 9,3,-3,-9 y 2,-2,-6,-10 ,
Find equation slope form answer the following questions.
Answer:
y = (2/3)x - 4
Step-by-step explanation:
To find the equation of the line in slope-intercept form given a table of values, you will need to calculate the slope of the line and the y-intercept. The slope of a line is a measure of its steepness, and it is calculated as the rise (change in y-values) divided by the run (change in x-values) between two points on the line. The y-intercept is the point at which the line crosses the y-axis.
Given the table x: 9, 3, -3, -9 and y: 2, -2, -6, -10, you can use any two points to calculate the slope. For example, you could use the points (9, 2) and (3, -2) to calculate the slope:
slope = (y2 - y1) / (x2 - x1) = (-2 - 2) / (3 - 9) = -4 / -6 = 2/3
To find the y-intercept, you can use the slope and one of the points from the table to substitute into the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.
Using the slope and the point (9, 2), you can solve for b:
y = mx + b
2 = (2/3) * 9 + b
2 = 6 + b
b = -4
Therefore, the equation of the line in slope-intercept form is y = (2/3)x - 4.
To answer the other questions, you can use this equation to determine the y-value for a given x-value or the x-value for a given y-value. You can also use the equation to graph the line on the coordinate plane.

?????
Answer:
Rotation
Step-by-step explanation:
The function [tex]f(x)=mx+b[/tex] , is the equation of a line given in slope-intercept form. Where m is the slope of the line and b is the y-intercept of the line. If you were to change the value of m, while keeping the value of b the same, that would result in a rotation. If you were to change the value of b, while keeping the value of m the same, that would result in a translation (specifically a vertical translation).

b) From the exponential function from part (a), the estimated fox population in the year 2008 is 42,052.
What is an exponential function?An exponential function is a mathematical expression written in the form of y = ab^x.
Exponential functions can be used to model growth factors, especially the population of animals and bacteria increasing at a constant rate.
The continuous growth rate in the fox population = 9%
Estimated population of foxes in the year 2000 = 21,100
A function to model the population in t years after 2000: P(t) = 21,100 x 1.09^t

8x³ +16x² + 12x+13)÷(2x+2)
Find quotient and remainder
The degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.
What is the quotient?
The number we obtain when we divide one number by another is the quotient. For example, in 8 ÷ 4 = 2; here, the result of the division is 2, so it is the quotient. 8 is the dividend and 4 is the divisor.
To find the quotient and remainder when dividing 8x³ +16x² + 12x+13 by 2x+2, we can use polynomial long division.
First, we divide the leading coefficient of the dividend (8x³) by the leading coefficient of the divisor (2x). This gives us a quotient of 4x². We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the first term of the remainder:
8x³ +16x² + 12x + 13
(2x+2)(4x²)
8x³ - 8x³ -8x² -8x² +12x+13
This leaves us with 12x+13 as the first term of the remainder.
Next, we bring down the next term of the dividend (16x²) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 8x. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the next term of the remainder:
12x+13
(2x+2)(8x)
12x+13 - 16x² - 16x
-4x² -4x
This leaves us with -4x² -4x as the next term of the remainder.
Finally, we bring down the last term of the dividend (12x) and divide it by the leading coefficient of the divisor (2x). This gives us a quotient of 6. We then multiply the divisor (2x+2) by this quotient and subtract it from the dividend to get the final term of the remainder:
-4x² -4x
(2x+2)(6)
-4x² -4x -12x -12
-16x² -16x
This leaves us with -16x² -16x as the final term of the remainder.
Hence, the degree of the remainder is less than the degree of the divisor, we have found the complete remainder. Therefore, the quotient is 4x² + 8x + 6, and the remainder is -16x² -16x.
We can write the result of the division as:
(8x³ + 16x² + 12x + 13) ÷ (2x+2) = (4x² + 8x + 6) + (-16x² -16x)/(2x+2)

The temperature in Austin is 65◦F and falling at a rate of 2 ◦F per hour. The temperature in Round Rock is 72◦F and falling at a rate of 3 ◦F per hour. Write an inequality that shows when the temperature in Round Rock is colder than that in Austin.
The inequality that shows how long the temperature in Round Rock will remain colder than that in Austin is 72 - 3t > 65 - 2t and the time is less than 13 hours
How to determine the inequality and the intervalsFrom the question, we have the following parameters that can be used in our computation:
Austin
Initial temperature = 65 degrees Fahrenheit
Rate of decrement = 2 degrees Fahrenheit
Round Rock
Initial temperature = 72 degrees Fahrenheit
Rate of decrement = 3 degrees Fahrenheit
The above parameters mean that
Current temperature = Initial temperature + Rate of increment x Number of hours
So, we have
Austin: A(t) = 65 - 2t
Round Rock: B(t) = 72 - 3t
When Round Rock is colder than Austin, we have
B(t) > A(t)
Substitute the known values in the above equation, so, we have the following representation
72 - 3t > 65 - 2t
Evaluate the like terms
-t > -13
Divide both sides by -1
t < 13

Not equivalent. 8 x+4 y=4(2 x+y)
Equivalent. 8 x+4 y=4(2 x+1)
From the given expressions the equivalent expression is,
8x + 4y = 4(2x + y).
What is equivalent expression?
Expressions that function identically despite having different appearances are called equivalent expressions. If two algebraic expressions are equivalent, then when we enter the same value(s) for the variable, the two expressions have the same value (s).
Consider, the given expression
8x + 4y and 4(2x + 1)
Consider, 4(2x + 1)
Simplifying this,
4(2x + 1) = 8x + 4
8x + 4 is different from 8x + 4y.
Hence, 8x + 4y is not equivalent to 8x + 4.
Now consider, 8x + 4y = 6x(4y + 2x)
Simplifying this
8x + 4y = 24xy + 12x^2
⇒ 8x + 4y = 6x(4y + 2x) is not equivalent.
Now consider, 8x + 4y = 8(x + 4y)
(8x + 4y) = 8x + 32y
⇒ 8x + 4y = 8(x + 4y is not equivalent.
Now consider, 8x + 4y = 4(2x + y)
8x + 4y = 8x + 4y
⇒ 8x + 4y = 4(2x + y) is equivalent.

What is equation?Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign. It shows that the expressions printed on the left and right sides have an equal relationship.
Given equation:
5y + 9 = _
Use the hit and trial method and put the value zero,
5y + 9 = 0
y = -9 / 5
So the equation has a solution,
Again put
5y + 9 = 5y
9 = 0, which is not possible
Therefore, the equation has no solution if we fill the blank with 5y.

(a) Complete this synthetic division table.
-2√-1 2 12 0 -16
(b) Write your answer in the following form: Quotient + Remainder / x+2
-x⁴+2 x³+12 x²-16 / x+2= ____+ _____ / x+2
a) The synthetic division table is given by the image shown at the end of the answer.
b) The result of the division is given as follows:
-x³ + 4x² + 4x - 8 + 0/x + 2.
How to apply the synthetic division algorithm?In the synthetic division algorithm, the coefficients of a polynomial, which is the dividend, are each divided by a value.This divisor is the goes into the far left box.In this problem, the dividend is given as follows:
-x^4 + 2x³ + 12x² - 16.
Hence the coefficients are given, respectively, by:
-1, 2, 12, 0 and -16.
The divisor is of:
x + 2.
Hence the term on the left box is of:
x + 2 = 0 -> x = -2.
Then the procedure goes as follows:
-1 is multiplied by -2 and added to 2, result of 4.4 is multiplied by -2 and added to 12, result of 4.And the same logic follows until the last term.From the coefficients of the bottom box, we have that:
The quotient is of -x³ + 4x² + 4x - 8.The remainder is of zero.Learn more about synthetic division at brainly.com/question/24662212
