Solution:

Slope of line joining two points ,

(x_{1},y_{1}) ,(x_{2},y_{2}) , is =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Take any two points that is , ordered pairs =(abscissa and Ordinate ), among four points given,suppose , (10,14) and (2,-2) or (2,-2) and (7,8).

=\frac{14+2}{10-2}\\\\=\frac{16}{8}=2 {\text{or}}, \frac{8-(-2)}{7-2}\\\\=\frac{10}{5}=2

So, if you choose any two distinct ordered pairs and find the slope between them using slope between two points , it will be equal to , 2.

11 The net force on a vehicle that is accelerating at a rate of 1.5 m/s² is 2,800 newtons. What is
ololo11 [35]

Answer:

Mass = 1867kg

Step-by-step explanation:

Given

Force = 2800N

Acceleration = 1.5m/s^2

Required

Determine the mass of the vehicle

This question will be answered using Newton's second law

Force = Mass * Acceleration

Substitute values for Force and Acceleration

2800 = Mass * 1.5m/s^2

Make Mass the subject

Mass = \frac{2800N}{1.5m/s^2}

Mass = 1866.6667kg

Mass = 1867kg ---- approximated

<em>Hence, the mass of the vehicle is 1867kg</em>

A stick 7 inches long is broken into two pieces, so that one piece is twice as long as the other one. How long are the two piece
marshall27 [118]

Hello from MrBillDoesMath!

Answer:

7/3 and 14/3 inches

Discussion:

Let P1 = "Piece 1" and "P2 = Piece 2", Then P2 = 2 * P1 and

P1 + P2 = 7       => as P2 = 2 P1

P1 + 2P1 = 7      =>

3P1 = 7             => divide both sides by 7

P1 = 7/3


Then P2 = 2 P1 - 2* (7/3) = 14/3

Thank you,

MrB

I need help on this question anyone know this ?
WITCHER [35]

Answer:

y = 4(2)^{x}

Step-by-step explanation:

An exponential function in standard form is

y = a b^{x}

Use ordered pairs from the table to find a and b

Using (0, 4), then

4 = a b^{0} ( note that b^{0} = 1 ), so

a = 4, then

y = 4 b^{x}

Using (1, 8)

8 = 4 b^{1} = 4b ( divide both sides by 4 )

b = 2

y = 4 (2)^{x} ← represents the values in the table

For f(x) =4x+1 g(x)=x²-5, find (f•g)(x)​
Inessa05 [86]

Answer:

(f · g)(x) = 4x³ + x² - 20x - 5

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Combining Like Terms
  • Expand by FOIL (First Outside Inside Last)

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 4x + 1

g(x) = x² - 5

(f · g)(x) is f(x)g(x)

<u>Step 2: Find (f · g)(x)</u>

  1. Substitute:                    (f · g)(x) = (4x + 1)(x² - 5)
  2. Expand [FOIL]:             (f · g)(x) = 4x³ - 20x + x² - 5
  3. Combine like terms:    (f · g)(x) = 4x³ + x² - 20x - 5
