What is the equation of the graphed linear model?<br><br> y = ? x + ?
miss Akunina [59]
Use slope intercept form for equation, which is y = mx +b. m is slope and b is the y-intercept.

Find slope by change in y over change in x. So pick two points, for example (0, 24) and (2, 20). Slope (m) will be
(y2-y1)/(x2-x1)
= (24-20)/(0-2)
= 4/-2
m = -2

Y-intercept is 24.

Equation is y = -2x + 24

Yakvenalex [24]

Answer:

5x +3y>-15

5(0)+3(0)

0+0=   0 > -15

Step by step explanation

We have to create a scenario that leads to an inequality of the form ax + b > c.

<em> </em>

<em>Word problem: A family went to an park. Entry fee of the park for a family is $20 and the cost of a ride is $10 per person. The family spent more than $100 on that ride. </em>

The required inequality is

Subtract 20 from both sides.

Divide both sides by 10.

It means the number of rides must be greater than 8.

Anika [276]

Answer:

-3x⁴ + 8x³ - 9x² - 7x - 9

General Formulas and Concepts:

  • Combining like terms

Step-by-step explanation:

<u>Step 1: Define expression</u>

(5x³ - 3x⁴ - 2x - 9x² - 2) + (3x³ + 2x² - 5x - 7)

<u>Step 2: Simplify</u>

  1. Combine like terms (x³):                    -3x⁴ + 8x³ - 9x² - 2x - 5x - 2 - 7
  2. Combine like terms (x):                     -3x⁴ + 8x³ - 9x² - 7x - 2 - 7
  3. Combine like terms (constants):       -3x⁴ + 8x³ - 9x² - 7x - 9
