How do I find the slope to this equation ?<br> 2х-Зу = 12

evablogger [386]

Answer:

slope = $\frac{2}{3}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x - 3y = 12 ( subtract 2x from both sides )

- 3y = - 2x + 12 ( divide all terms by - 3 )

y = $\frac{2}{3}$ x - 4 ← in slope- intercept form

with slope m = $\frac{2}{3}$

Question 14(1 point)Find the rate of change of Pete's height from 3 to 5 years.17.Time (years) 123 4 15 16Height/in.) 27 35 37 4

kupik [55]

The rate of change of Pete's height from 3 to 5 years can be determined as,

$\begin{gathered} \frac{\Delta H}{\Delta t}=\frac{H_5-H_3_{}}{5-3} \\ =\frac{45-37}{2} \\ =\frac{8}{2} \\ =4 \end{gathered}$

Thus, the required rate of change from 3 to 5 years is 4 in/year.

A media company wants to track the results of his new marketing plan so the video production manager recorded the number of use

konstantin123 [22]

Answer:

$f(x)=5120(5)^{x}$

Step-by-step explanation:

From the image, f(x) and x are rlated by

$f(x)=a( {b})^{x}$

where b is the common ratio

We first find the value for b

$\frac{6400}{5120}= 5$

$\frac{8000}{6400}= 5$

$\frac{10000}{8000} = 5$

$\frac{12500}{10000} = 5$

$\frac{15625}{12500}=5$

so we can say the common ratio, b=5

we put in any value of f(x) and the corresponding value for x to find a value

Let put x=0 and f(x)=5120

This implies that

$5120 = a(5)^{0}$

but

$5^{0} = 1$

Hence a=5120

Thus the equation which model the relationship between the weeks and the viewers is

$f(x)=5120(5)^{x}$

Select True or False for each statement.

mote1985 [20]

<h2>Answer:</h2>

For a real number a, a + 0 = a. TRUE

For a real number a, a + (-a) = 1. FALSE

For a real numbers a and b, | a - b | = | b - a |. TRUE

For real numbers a, b, and c, a + (b ∙ c) = (a + b)(a + c). FALSE

For rational numbers a and b when b ≠ 0, is always a rational number. TRUE

<h2>Explanation:</h2>

<u>For a real number a, a + 0 = a. </u><u>TRUE</u>

This comes from the identity property for addition that tells us that<em> zero added to any number is the number itself. </em>So the number in this case is $a$ , so it is true that:

$a+0=a$

For a real number a, a + (-a) = 1. FALSE

This is false, because:

$a+(-a)=a-a=0$

For any number $a$ there exists a number $-a$ such that $a+(-a)=0$

For a real numbers a and b, | a - b | = | b - a |. TRUE

This is a property of absolute value. The absolute value means remove the negative for the number, so it is true that:

$\mid a-b \mid= \mid b-a \mid$

For real numbers a, b, and c, a + (b ∙ c) = (a + b)(a + c). FALSE

This is false. By using distributive property we get that:

$(a + b)(a + c)=a^2+ac+ab+bc \\ \\ a^2+ab+ac+bc \neq a+(b.c)$

For rational numbers a and b when b ≠ 0, is always a rational number. TRUE

A rational number is a number made by two integers and written in the form:

$\frac{u}{v} \\ \\ v \neq 0$

Given that $a \ and \ b$ are rational, then the result of dividing them is also a rational number.
