Answer:
3
Step-by-step explanation:
5 is greater than 2 and two is negative so the answer is positive
Simplify: 40y^3 - 8y^2 + 16y/8 y^2
40y^3 + -8y^2 + 2y^3
Combine terms: 40y^3 + -8y^2 + 2y^3
(40y^3 + 2y^3) + (-8y^2)
Answer: 42y^3 + -8y^2
If u don't it could change the value of the number
Answer:
See below
Step-by-step explanation:
<h3>Part A</h3>
Standard form is Ax + By = C
<u>x - price of adult tickets, y - price of child tickets, the equation in the standard form is:</u>
- 15x + 9y = 90 ⇒ 5x + 3y = 30
<h3>Part B</h3>
<u>y-intercept is obtained when x = 0</u>
- 15*0 + 9y = 90
- 9y = 90
- y = 10
It represents the amount of child tickets if no adult tickets sold
<u>x-intercept is obtained when y = 0</u>
- 15x + y*0 = 90
- 15x = 90
- x = 6
It represents the amount of adult tickets if no child tickets sold
<h3>Part C</h3>
<u>Converting the equation into slope-intercept form of y = mx + b</u>
- 5x + 3y = 30
- 3y = -5x + 30
- y = -5/3x + 30/3
- y = -5/3x + 10
<h3>Part D</h3>
- The slope is -5/3. It represents the negative ratio of ticket prices
