Answer:
h = 13.333 +693.333/r
Step-by-step explanation:
For h hours, Brandee's pay will be ...
pay = 40r +(h -40)(1.5r) . . . . 40 hours at rate r + overtime (h-40) hours at 1.5r
pay = 40r +1.5hr -60r . . . . . eliminate parentheses
pay = 1.5hr -20r . . . . . . . . . . collect terms
Solving for h, we have ...
pay +20r = 1.5hr . . . . . . . . . . add 20r
h = (pay +20r)/(1.5r) . . . . . . . . divide by 1.5r
For the given pay of 800 +240 = 1040, we have ...
h = (1040 +20r)/(1.5r)
h = 13.333 +693.333/r . . . . . simplify to 2 terms

<em>Additional comments</em>
You need to know r to find the number of hours Brandee worked. She got paid $800 for a presumed 40-hours of regular time, so made r = $20 per hour. The above formula will tell you she worked 48 hours in the pay period.
Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:

Vertex:

X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)

Answer:
M = -2
b = -10
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
m = (-8 -0)/(-1- -5)
= (-8-0)/(-1+5)
= -8/4
= -2
We now want to find the y intercept
y = mx+b is the slope intercept form of the equation
y = -2x+b
Using the point (-5,0)
0 = -2(-5) +b
0 = 10+b
Subtract 10 from each side
-10 = 10-10+b
-10 =b
The y intercept is -10
y= -2x-10
The restrictions are what the denominator can not be. The denominator cannot be zero. So if the denominator has x+1 in it. If you put -1 in place of x. You would get zero. -1 is a restriction
