Answer:
see explanation
Step-by-step explanation:
To find the x- intercepts let y = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
x- intercepts are x = - 2 and x = 4
The vertex lies on the axis of symmetry which is located at the midpoint of the x- intercepts, thus
=
= 1
Substitute x = 1 into the equation for corresponding value of y
y = (1 - 4)(1 + 2) = - 3 × 3 = - 9
vertex = (1, - 9)
The expression for the number of ballon bouncer games played at the arcade is :
Let :
- Glimmer arcade, g = $2 per game
- Ballon bouncer, b = $3 per game
- Total game tokens = 35
<u>Her spending could be represented using the expression</u> :
- 2 + 3b = 35 ; b = number of ballon bouncer games played
2 + 3b = 35
3b = 35 - 2
3b = 33
b = 33/3
b = 11
Therefore, the Number of Ballon bouncer games played is 11.

The slope of the line is the change in y values over the change in x values, since for horizontal line, the y values do not change then, the slope is zero.
If the line is horizontal, this means that whatever the value of the x-coordinate (abscissa) is, the y-coordinate (ordinate) will always be 10.
The intercept of the line is 10. So, third statement is not true.
Since the equation of the line is zero and its y-intercept is zero, using the equation of the line which is,
y = mx + b
where m is slope and b is y-intercept. The equation of the line is,
y = 0x + 10 ; y = 10
