Answer:
No. There are two solutions to the point x=-2: 9 and 5.
Step-by-step explanation:
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, for the same x position, then the graph is not a function.
Store A, which is $0.97/pound (1.94/2)
Store B is $3.22, Store C is $1.83, and Store D is $2.64
Answer:
142
38
Step-by-step explanation:
Answer:
b = 36
Step-by-step explanation:
Assuming this is a right triangle with hypotenuse = c and legs a and b
Then using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + b² = c², and substituting values
15² + b² = 39², that is
225 + b² = 1521 ( subtract 225 from both sides )
b² = 1296 ( take the square root of both sides )
b =
= 36
