Answer:
-5
Step-by-step explanation:
Since you are given [tex]g(x)[/tex] and what x is equal to (in this case, -3), all you have to do is plug the x back into the original equation.
[tex]g(x) = -3 - 2 = -5[/tex]
n - Are x = 4 and y = 8 solutions of the equation: y = x² - 2x + 1? Circle: Yes or No
Answer:
No
Step-by-step explanation:
put 4 where x is and 8 where y is
y = x² - 2x + 1
does
8 = 4^2 -2(4) + 1
8 = 16 -8 + 1
8 = 9

Make a scatter plot of the data pairs, (year, revenue). Draw a trend line and write its equation. Predict the revenue of US theme parks in 2012. Someone help me please.
i think its 9.9 but if its not that its 8.7
The revenue of US theme parks in 2012 is 14.5 in dollars.
What is scatter plot?Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.
From the given table, (1990, 5.7), (1992, 6.5), (1994, 7.0), (1996, 7.9), (1998, 8.7), (2000, 9.6), (2002, 9.9), (2004, 10.8), (2006, 11.5).
Using the coordinates (1990, 5.7) and (1992, 6.5), we get
Slope m=(6.5-5.7)/(1992-1990)
= 0.8/2
= 0.4
Substitute m=0.4 and (x, y)=(1990, 5.7) in y=mx+c, we get
5.7=0.4×1990+c
c=5.7-796
c=790.3
Substitute m=0.4 and c=-790.3 in y=mx+c, we get
y=0.4x-790.3
Substitute x=2012, we get
y=0.4×2012-790.3
y=804.8-790.3
y=14.5
Therefore, the revenue of US theme parks in 2012 is 14.5 in dollars.

Price is $20.00 Sales Tax is 4% What is the total cost?
Answer:
your answer is correct
Step-by-step explanation:
i don't know why i it didn't work
If the price of an item is $20.00 with a sales tax of 4%, the total cost of the item is $20.80.
How the total cost is determined using the sales tax:The total cost involves adding the price and the sales tax amount.
We can compute the total cost by determining the sales tax factor using the sales tax rate as follows:
The price of the item = $20.00
Sales tax = 4% = 0.04 (4/100)
The sales tax factor = 1.04 (1 + 0.04)
Thus, the total cost, including the price and the sales tax, is $20.80 ($20 x 1.04).

You're going to multiply 3 by 2 which gives you 6. you then have 6 over 2. Next find a number that goes into both of them which is 2 in this case. So now you divide the top and bottom by 2, so now you have 3 because two divided by two is zero, that is as small as it gets.

which piece wise function is graphed below
Answer:
Option A
Step-by-step explanation:
Here is how to approach the problem:
We see that all our restrictions for all four answer choices are relatively the same with a couple of changes here and there.
One way to eliminate choices would be to look at which restrictions don't match the graph.
At x<-5, there is a linear function that does have a -2 slope and will intersect the x axis at -7. The line ends with an open circle, so any answer choice with a linear restriction of x less than or equal to -5 is wrong. This cancels out choices C and D.
Now we have two choices left.
For the quadratic in the middle, the vertex is at (-2,6) and the vertex is a maximum, meaning our graph needs to have a negative sign in front of the highest degree term. In our case, none of our quadratics left are in standard form, and instead are in vertex form.
Vertext form is f(x) = a(x-h)^2 + k.
h being the x-coordinate of the vertex and k being the y-coordinate.
We know that the opposite of h will be the actual x-coordinate of the vertex, so if our vertex is -2, we will see x+2 inside the parenthesis. This leaves option A as the only correct choice.
