$\text{The standard form a linear equation is given by the formula:}\\
Ax+By+C=0\\\\
5x = 4y - 3\\
5x-4y+3=0 \Rightarrow A
$

$-6y+2x=18\\
-6y=-2x+18\\
y=\dfrac{-2}{-6}x+\dfrac{18}{-6}\\
y=\dfrac{1}{3}x-3\\\\
m=\dfrac{1}{3}$

Answer:

The first is a Postive slope. the Second is a Zero slope

Step-by-step explanation:

Becuase the first gradully increases. meaning positive

and the 2nd is a zero because there is no slope. it's a stright line. level ground. no up hill or down hill

Hope this helps!

If f(x)=x^2−8x and g(x)=−12x^2 what is g(f(−4))?

Korolek [52]

Answer:

-27648

Step-by-step explanation:

In this problem, we are looking for the function of g in terms of the function f. Simply put, we just replace the variable x in the function g with f(-4).

Step 1, writing g(f(-4)):

$g(f(-4))=-12(f(x))^2$

Great! Let us substitute f(x) with the given expression.

Step 2, substituting and simplifying:

$\\g(f(-4))=-12(x^2-8x)^2\\g(f(-4))=-12((-4)^2-8*(-4))^2\\g(f(-4))=-12(16+32)^2\\g(f(-4))=-12*2304\\g(f(-4))=-27648$

g(f(-4) is $\fbox{-27648}$ .

I hope this helps! Let me know if you have any questions :)

The ordered pair given in the first row in the table can be written using function notation as?

ioda

These are two questions and two answers.

Question 1. The ordered pair given in the first row in the table can be written using function notation as?

Answer: f(-2) = 1

Justification:

In functions, the notation f(x) denotes the image (ouput) obtained when you apply the rule (function) to the value x, i.e. x is the input.

So, for example, the image of x = 5 is f(5), the image of x = 2,000 is f(2,000), the imaga of x = - 100.5 is f(-100.5).

In the table, the first row shows that the image of x = -2 is 1, so f(-2) = 1, and that is the answer to the question.

Question 2. f(x) = –2 when x is?

Answer: x = 4.

Justification.

You are requested to find which value of x makes the function f(x) equals -2.

Therefore, you have to see that in the third row of the table it is shown that f(x) is - 2 when x = 4., and that is the answer.

All the following expressions mean the same and are used when you deal with functions:

the ordered pair (4, -2),
the image of 4 is - 2
the preimage of -2 is 4
f(4) = -2
f(x) = -2, when x = 4.
