Answer:
2/3
Step-by-step explanation:
5/9 + 1/9
= 6/9
= 2/3 in simplest form
The third graph represents a function.
In a function, every input (x value) has <em>exactly</em> one output (y value). If even a single input has zero or two outputs, the graph does not represent a function.
A good way of testing this is using a vertical line. As you move a vertical line from left to right across a graph, it should always be touching exactly one point on the graphed line.
In this case, every graph fails this vertical line test except for the third graph, so the third graph represents a function.
Answer:
I'd say multiply the numerators then the denominators and at the end simplify at least thats how I multiply fractions :)
Answer:
78.75 cm cubed
Step-by-step explanation:
To find the volume of the prism, use the formula V = l*w*h where l = 4.5, w = 5 and h = 3.5.
So the volume is V = 4.5*5*3.5 = 78.75
F+g(x) = f(x) + g(x) = 3x-1 + x+2 = 4x+1
