Three x plus four equals forty three?
4x-3 is the answer because you subtract like terms. 7x-3x=4x and -5-(-2)=-3
Answer:
6+18x
Step-by-step explanation:
=6(1+3x)
=6×1+6×3x
=6+18x
Answer:
The maximum height of the ball is 28.2 yards.
Step-by-step explanation:
When we have a quadratic equation in the following format:
The maximum value happens when
The maximum value will be 
In this problem, we have that:
So
The maximum height is:
The maximum height of the ball is 28.2 yards.

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.
