Which best describes the transformation that occurs from the graph of f(x)=x^2 to g(x)=(x-2)^2+3?? ​
Leokris [45]

answer right 2, up 3

any function with the following form is a transformation from f(x) = x²

g(x) = (x – a)² + b

were a moves the function to the right when a is a positive number and to the left when its a negative number, and b moves the function up when b is positive and down when its negative.

then for a=2 positive and b=3 positive, we have

Rus_ich [418]

Answer:

  1/9

Step-by-step explanation:

Pairs that sum to 5 are (1,4), (2,3), (3,2), (4,1). There are 4 ways you can get that sum out of 36 possible outcomes. Assuming each outcome is equally likely, the probability of a sum of 5 is ...

The system with one and only one solution set is called a/an system
beks73 [17]

Answer:

Consistent and Independent System

Step-by-step explanation:

A system with at least one solution is a consistent system.  A consistent system is said to be independent if it has <u>exactly one solution</u> (often referred to as the <em>unique</em> solution).  The graphs intersect at exactly one point, which gives an ordered-pair (x, y) as the solution of the system.

A porch has the shape of a quarter circle with a diameter of 5 ft. What is the approximate area of the porch, rounded to the nea
GalinKa [24]
Area=pi times radiius^2
radius=diameter/2
diamter=5
radius=5/2=2.5
pi=3.14 aprox
area=3.14 times 2.5^2
area=3.14 times 6.25
area=19.625 ft^2

Select the graph of the solution. Click until the correct graph appears. 3x + 1 &lt; 7 (line graph)
WARRIOR [948]
3x + 1 < 7...subtract 1 from both sides
3x < 7 - 1
3x < 6 ...divide both sides by 3
x < 6/3
x < 2

there will be an open circle on 2....because the problem has no equal sign...the line will be shaded to the left...because it is less then.
