Mathematics
1 answer:
kumpel [21]4 years ago

Answer:

B

Step-by-step explanation:

The problem wants you to PLUG IN x into the correct equation.

1) f(-1) means -1 equals x

f(3) means 3 equals x

For example g(9) means 9 = x and f(3/5) means 3/5 = x and so on.

2) Now that you know x equals two numbers -1 and 3 you have to plug them into a equation.

3) Which equation do you plug it in you may ask? You must plug in -1 into x^2 +3 BECAUSE the condition next to it says you can only plug in numbers to x^2+3 greater than or equal to -1 and less than 2. Therefore, you can plug in -1 to this equation.

-1^2 +3 = <u>4</u>

4) Now you have the number 3. Where do you think we should plug #3 into? Well you can plug it in to the first equation because the condition only allows numbers less then -1. the only option is the last one!!

1, for x >= 2 because 3 is certainly bigger than 2.

This means any number greater than or equal to 2 has to be 1.

SO OUR ANSWER IS 4 AND 1

The graph shows the functions f(x), p(x), and g(x):
Tatiana [17]
<h3>Answer:</h3>
  • A. (x, y) = (1, -1)
  • B. (1, -1), (2, 0)
  • C. (0, 3). This is where their graphs cross, meaning g(x) = f(x) at that point.
<h3>Step-by-step explanation:</h3>

A solution to a pair of equations is the set of points where their graphs intersect. Points in that set will satisfy both equations, which is what "solution" means.

Here, the graphs of p(x) and f(x) each intersect the graph of g(x) in one place. Hence f(x) = g(x) has one solution, as does p(x) = g(x).

Finding the solution is a matter of reading the coordinates of the point of intersection from the graph.

A. The graphs interesect at x=1, y=-1.

B. Any point on the red line is a solution. We already know one of them from part A. Another is the x-intercept, where y=0. That point is (2, 0).

C. g(x) intersects f(x) at their mutual y-intercept: y = 3. x = 0 at that point.

Answer: perimeter = 204

Area = 1325

Step-by-step explanation:

To find perimeter you find the sum of all the sides which is 97 + 54 + 53 = 204. To find area you multiply base times height divided by 2. In this problem it is 53 * 50 divided by 2 equals 1325

The ordered pairs below represent a relation between x and y.(-3,-3), (-2,0), (-1,3), (0,6), (1,9), (2,12)Could this set of orde
GarryVolchara [31]
The set of ordered pairs generate a linear function because all the points lie in the same line that is described by the equation y = 3x + 6. The equation is found by choosing any two ordered pair and constructing the y =mx+b equation form where m is the slobe and b is the y-intercept.
