Answer:
Amount of water in each balloon = 300 milliliter
Step-by-step explanation:
Given:
Amount of water used in balloon = 6 liter
Number of water balloon = 20 balloon
Find:
Amount of water in each balloon
Computation:
Amount of water used in balloon = 6 x 1000
Amount of water used in balloon = 6,000 milliliter
Amount of water in each balloon = Amount of water used in balloon / Number of water balloon
Amount of water in each balloon = 6,000 / 20
Amount of water in each balloon = 300 milliliter
Answer:
X intercepts are points where a function intersects or cuts through the x axis where y=0.
Step-by-step explanation:
In the function given which is f(x) =x^2 +4x + 3 we see that this is a parabola of which when the graph is drawn it has a U shape so when finding x intercepts of this function it is those points on the function where the graph cuts the x axis and at those two points f(x)= 0, so here Mathieu had made a mistake of factorizing and equating the x intercepts for this function.
For finding the X intercepts let f(x) = 0
therefore 0= x^2 + 4x + 3 now we solve for x
0= (x+1)(x+3)
(x+1)= 0 or (x+3)=0
therefore x=-1 or x=-3
now if you substitute these values onto the function they give f(x)= 0,
f(-1) = (-1)^2 + 4(-1) + 3 = 0
f(-3) = (-3)^2 + $(-3) + 3 =0
now let us look at Mathieus answer which is x+1 = x+3 yes these x values do give the same y value but they are not equal because if you can actually solve this further you would not get a defined answer. Both these are factors of the function but are not actually equal as the function would not be able to be drawn if this was the case.

Answer:
- With x being the number of people attending the party, and c(x) the cost in dollars.
Explanation:
The <em>total cost </em>is comprised of three costs, namely<em> the flat fee for the room rental</em> ($150), <em> the charge person for the Italian buffet </em>($14 per person), and <em>the tip</em> (18% added to the cost of the food). With this you can build your equation:
Where x respresents the number of people attending the party.
Convert 18% to its decimal form, which is 0.18 and simplify the equation:
Hence, calling the function c(x), it is:
, with x being the number of people attending the party, and c(x) the cost in dollars.
