Find the slope of the line 3x - y = 15

Mathematics
1 answer:
MakcuM [25]2 years ago
8 0

Answer:

<u>3</u>

Step-by-step explanation:

Rearrange in the slope-intercept form :

  • 3x - y = 15
  • y = 3x - 15

Comparing this to the standard equation :

  • y = mx + c
  1. m = slope
  2. c = y-intercept

  • On comparing, it is clear that the slope of the line is <u>3</u>

Which of the following statements is not true of deductive reasoning? It is used when you solve an equation in algebra. It is us
erastova [34]

<u>Answer:</u>

"It is used when you solve an equation in algebra" is the untrue statement.

<u>Step-by-step explanation:</u>

"It is used when you solve an equation in algebra."

When you solve an algebra problem, you are not using deductive reasoning. You are using the information in front of you to correctly answer.

"It is used to make broad generalizations using specific observations."

This is exactly what deductive reasoning is, you are making generalizations and coming up with your own conclusions through observation.

"It is used to prove basic theorems."

This is also true, you can use deductive reasoning by using your specific observations and drawing conclusions to prove the theorems.

"It is used to prove that statements are true."

Using your own observations, you can draw your own conclusions to prove what you are saying is factual.

Given the function f(x) = 4(x+3) − 5, solve for the inverse function when x = 3.
Dimas [21]
Hello,

f(x)=4(x+3)-5=4x+12-5=4x+7

y=4x+7==>c=(y-7)/4

f^(-1)(x)=(x-7)/4
f^(-1)( 3)=(3-7)/4=-4/4=-1

HELP

You did not provide any question. I will give general advice.

Pythagorean Theorem: a² + b² = c²

If you know two sides, you know ll three sides.

A house sits in the shade.

The house is 18 feet tall. The shadow is 24 feet long. What is the hypotenuse of this triangle?

We know a and b here! a=18, b=24.

18 * 18 = 324.

24 * 24 = 576.
324+576 = 900

The square root of 900 is what will be your answer:

18*18 + 24*24 = 30*30.

I hope this helps!
