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
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>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.
Answer:
-3x⁴ + 8x³ - 9x² - 7x - 9
General Formulas and Concepts:
Step-by-step explanation:
<u>Step 1: Define expression</u>
(5x³ - 3x⁴ - 2x - 9x² - 2) + (3x³ + 2x² - 5x - 7)
<u>Step 2: Simplify</u>
- Combine like terms (x³): -3x⁴ + 8x³ - 9x² - 2x - 5x - 2 - 7
- Combine like terms (x): -3x⁴ + 8x³ - 9x² - 7x - 2 - 7
- Combine like terms (constants): -3x⁴ + 8x³ - 9x² - 7x - 9
