Answer:
$54.60
Step-by-step explanation:
45.50*.20=9.10
9.10+45.50=54.60
Answer:
All real numbers are solutions!
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+4=9+5(x−1)
Step 1: Simplify both sides of the equation.
5x+4=9+5(x−1)
5x+4=9+(5)(x)+(5)(−1)(Distribute)
5x+4=9+5x+−5
5x+4=(5x)+(9+−5)(Combine Like Terms)
5x+4=5x+4
5x+4=5x+4
Step 2: Subtract 5x from both sides.
5x+4−5x=5x+4−5x
4=4
Step 3: Subtract 4 from both sides.
4−4=4−4
0=0

Answer: Yes it is a function</h3>
Each point listed is of the form (x,y). The x coordinate is always listed first. We dont have any repeat x values, so this is enough to conclude we have a function.
If you wanted to, you could graph each point given on the same coordinate grid. Note how none of the points stack on top of each other. Or put another way, note how it is impossible to draw a single straight line through more than one point graphed. This graph passes the vertical line test.
A function is where plugging in any x value leads to exactly one y value.
If you had two points like (5,2) and (5,7) then the input x = 5 leads to more than one output y = 2 and y = 7 at the same time, making this example not a function.
