Answer:y=5
Step-by-step explanation:
In total, the water level in Wei's pool increased by four centimeters. first, you would take negative one and nine-tenths, then you would add the three and one-half increase. This would give you one and six-tenths. You would then also add the two and four-tenths increase, leaving you with four.
Answer:
c
Step-by-step explanation:
The function f(x) = -5x³ + 3x² + x - 9 is a cubic function with the form:
f(x) = ax³ + bx² + cx + d, where a = -5, dictates the end behavoir of the function.
Since a is negative, then as x → -∞, y → ∞, and as x → ∞, y → -∞.
The solution of the given expression will be (3d−3)(d+7)(d−9).
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The solution of the given expression will be:-
E = (3d−3)(d+7)(d−9).
E = ( 3d² + 18d -21 ) ( d- 9 )
E = ( 3d³ + 18d² -21d - 27d² -162 +189 )
E = ( 3d³ + 9d² - 21d + 27 )
Therefore the solution of the given expression will be (3d−3)(d+7)(d−9).
