Answer:
x=9
Step-by-step explanation:
4x+6+7x+15=120 combine like terms it becomes 11x+21 =120 take away 21 from 120 , leaves you with 11x=99 divide by 11 to get x alone leaves you with x=9 :)
Answer:
27b^18
Step-by-step explanation:
The applicable rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
___
(3b^8·b^-2)^3 = (3b^(8-2))^3 = (3b^6)^3
= 3^3·b^(6·3)
= 27b^18
Answer:
yes
Step-by-step explanation:
Answer:
- 2 seconds to maximum height
- 20 meters maximum height
- 4 seconds to reach the ground
Step-by-step explanation:
The function can be graphed using a graphing calculator, geometry app, or spreadsheet. One such graph is attached. Often, these tools are capable of identifying extrema and intercepts.
__
<h3>extreme</h3>
The vertex of the graph is reported as (x, y) = (2, 20). This means the maximum height is reached after 2 seconds. That maximum height is 20 meters.
__
<h3>intercept</h3>
The drop is launched from ground level at x = 0 seconds. It returns to ground level at x = 4 seconds.
