Answer:

The correct option is <u>A) y - 1 = -4(x-2)</u> is an equation of the line going through (3, -6) and (1,2)

Step-by-step explanation:

we have to find which is not an equation of the line going through (3, -6) and (1,2)

Put   (3, -6) and (1,2) in Part A)

y - 1 = -4(x-2)

for (3, -6)

-6 - 1 = -4(3-2)

-7 ≠ -4

for (1,2)

2 - 1 = -4(1-2)

    1 = -4(-1)

     1 ≠ 4

This is not an equation of the line going through (3, -6) and (1,2)

Put   (3, -6) and (1,2) in Part B)

y - 2 = -4(x-1)

for (3, -6)

-6 - 2 = -4(3-1)

-8 = -8

for (1,2)

2 - 2 = -4(1-1)

    0= 0

This is an equation of the line going through (3, -6) and (1,2)

   

Put   (3, -6) and (1,2) in Part C)

y + 6 = -4(x-3)

for (3, -6)

-6 + 6 = -4(3-3)

       0 = 0

for (1,2)

2 + 6 = -4(1-3)

    8= 8

This is an equation of the line going through (3, -6) and (1,2)

   

Put   (3, -6) and (1,2) in Part D)

y  = -4x + 6

for (3, -6)

-6  = -4(3) + 6

       -6 = -6

for (1,2)

2  = -4(1) + 6

 2 = 2

This is an equation of the line going through (3, -6) and (1,2)

Hence, The correct option is <u>A) y - 1 = -4(x-2)</u> is an equation of the line going through (3, -6) and (1,2)

Which expressions are equivalent to 4(x+1) + 7(x+3)? Select two answers.
Natalija [7]

Answer:

9(x+3) + 2(x+3) or 10(x+2) +(x+5)

Step-by-step explanation:

First you want to distribute the equation.

4(x+1) + 7(x+3) multiplied out is

4x + 4 + 7x + 21

Now we add like terms so it comes out to

11x + 25

Two expressions that can come out to equal 11x + 25 is. 9(x+3) + 2(x+3) or 10(x+2) +(x+5)

Which of these points lies on the circle with the center (2,3) and radius 2?
yan [13]

Answer:

The answer to your question is the letter A.

Step-by-step explanation:

Data

Center = (2, 3)

radius = 2

Process

1.- Find the equation of the line

              (x - h)² + (y - k)² = r²

-Substitution

              (x - 2)² + (y - 3)² = 2²  

-Simplification

              (x - 2)² + (y - 3)² = 4

-Evaluate the points in the equation

A. (4, 3)

              (4 - 2)² + (3 - 3)² = 4

                   2² + 0 = 4

                           4 = 4     This point lies in the circle

B (-1, 0)

              (-1 - 2)² + (0 - 3)² = 4

                        -3² + (-3)² = 4

                          9 + 9 = 4   This point is not part of the circle

C. (1, 3)

              (1 - 2)² + (3 - 3)² = 4

                 (-1)² + (0)² = 4

                            1 = 4          This point is not part of the circle

D. (3, 4)

              (3 - 2)² + (4 - 3)² = 4

                     1² + 1² = 4

                            2 = 4          This point is not part of the circle

Let f(x)=3x+5 and g(x)=x^2 find (f-g)(x)
dlinn [17]

Answer:

(f - g)(x) = -x² + 3x + 5

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Function Notation
  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x + 5

g(x) = x²

(f - g)(x) is f(x) - g(x)

<u>Step 2: Find (f - g)(x)</u>

  1. Substitute:                   (f - g)(x) = 3x + 5 - x²
  2. Rewrite:                       (f - g)(x) = -x² + 3x + 5

A 12-foot ladder is placed four feet from the base of a wall.
nikitadnepr [17]

Answer:8sqrt 2 or sqrt 128

Step-by-step explanation:

We can use the Pythagorean Theorem. Since the ladder is leaning against the wall, it is the hypotenuse. It is also 4 feet away from the wall so 12^2-4^2=b^2 b^2=128 so b=8sqrt 2 or sqrt 128.
