Answer:
$110
Step-by-step explanation:
We are looking for the decrease in money per desk purchased. Because the x-axis is the number of desks purchased, what we have to find is the (opposite) of the slope. The formula to represent slope can be written as:
We can substitute the points given, (2, 480) and (5, 150) and simplify:
We would multiply by -1 because we are asking for the decrease, and negative increase is decrease. -1 * -110, gives us $110

The arnold family arrived at the beach at 10:30 A.M.
10:30
Add 3 hours and 3/4 minutes to that
3/4 = 75% of 60
.75 * 60 = 45
3 hours and 45 minutes
10:30 >> 3 hours more = 1:30
1:30 + 45 mins = 2:15
Answer would be: They left at 2:15
Answer:
The formula for this quadratic function is x*2 +6x+13
Step-by-step explanation:
If we have the vertex and one point of a parabola it is possible to find the quadratic function by the use of this
y= a (x-h)*2 + K
Quadratic function looks like this
y= ax*2 + bx + c
So let's find the a
y= a (x-h)*2 + K where
y is 13, x is 0, h is -3 and K is 4
13= a (0-(-3))*2 +4
13=9a +4
9=9a
9/9=a
1=a
The quadratic function will be
y= 1(x+3)*2 + 4
Let's get the classic form
(x+3)*2 = (x+3)(x+3)
(x*2+3x+3x+9)
x*2 +6x+13
f(0) = 13
