Answer:
C=14
Step-by-step explanation:
To find the minimum value, graph each of the inequalities. After graphing each inequality, test a point and shade the region that satisfies the inequality. Once all inequalities have been shaded, find the region where they all overlap. The region will be bounded by intersection points. Test each of these points into C=x+3y. The least value for C is the minimum.
(14,0) (0,17.5) (3.08,3.64)
C=14+3(0) C=0+3(17.5) C=3.08 + 3(3.64)
C=14 C=52.5 C=14
A. 18x - 3
Porque:
(f+g)(x)=?
(f+g)(x)= (3x + 10x) + (5x - 3)
(f+g)(x)= 3x + 10x + 5x - 3
(f+g)(x)= 3x + 10x + 5x -3
(f+g)(x)= 18x - 3 ✔️
Answer:
I think C. is correct
Step-by-step explanation:
Just trust me, I'm smart ;)
Hi there !
Y = 7x - 53
Y = -4x + 35
I always used substitution to solve equations so we gonna use it here as well :)
-----------------------------------------------------------------------------------------------------
We gonna solve y = 7x - 53 for y
Let's start by substitute 7x - 53 for y in y = -4x + 35
y = -4x + 35
7x - 53 = -4x + 35
Common terms
7x + 4x = 35 + 53
11x = 88
divide both sides by 11
11x/11 = 88/11
x = 8
Now, since we have the value for x, it will be easier for us to find Y. So, we gonna use the value of x which is 8 to find y.
In order to find the value for y, we must substitute 8 which is the value for x in y = 7x - 53
y = 7(8)-53
y = 56 - 53
y = 3
The final answer is : X = 8 and Y= 3
-------------------------------------------------------------
The correct option is B
(8,3)

Answer:
I disagree with the statement.
Step-by-step explanation:
Speed of the ball is different at each position:
This rhymes with the laws of physics because a ball placed at a certain height or on a certain slope will have a different speed (when thrown or rolled down) from a ball placed at a different height or on a different position on a plane.
There is no way to define probability density because i can't calculate the probability at just one point:
This statement is self-opposing as probability density is meant for times when probability value cannot be calculated or found for every given point! It is meant for continuous variables such as the one you're dealing with here - speed. The way to do this is to derive a probability density value for the variable in question (speed of the ball) for specific position intervals. Hence, divide the positions into intervals e.g.
A - B, B - C, C - D and so on.
So, probability density is used when you cannot the probability at just one point.
