Answer:
The coordinates of the image trapezoid are
A"(-4,5), B''(-1,5), C''(0,3), D''(-5,3)
The pre-image was first reflected in the line y=x, so the mapping will be
The resulting coordinates were then translated 4 units right;
For A''(-4,5), y+4=-4 and x=5
This means y=-8, x=5
Hence A(5,-8)
For B''(-1,5), y+4=-1, and x=5.
This means y=-5 and x=5
B(5,-5)
For C''(0,3), C(3,-4)
For D''(-5,3), D(3,-9)

Answer:
n = 60
Step-by-step explanation:
Solve for n:
(3 n)/5 = 36
Multiply both sides of (3 n)/5 = 36 by 5/3:
(5×3 n)/(3×5) = 5/3×36
5/3×3/5 = (5×3)/(3×5):
(5×3)/(3×5) n = 5/3×36
5/3×36 = (5×36)/3:
(5×3 n)/(3×5) = (5×36)/3
(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:
n = (5×36)/3

n = 5×12
5×12 = 60:
Answer: n = 60
Below is the solution:
f(x)=−4(x2−6x+9−9)−29
<span> (</span>x2−6x+9)=(x−3)(x−3)
f(x)=−4((x−3)2−9)−29
f(x)=−4(x−3)2−4(−9)−29
f(x)=−4(x−3)2+36−29
f(x=−4(x−3)2+7
f(x)=−4(x−3)2+7
That's
the equation we got by completing the square.
y=a(x−h)2+k
That's
the formula of a parabola in "vertex" form. Notice the similarity?
The two are equal if we say
y=f(x)
a=−4
h=3
k=7
Therefore the answer is C, <span>−4(x − 3)2 + 7; The maximum height of the water is 7 feet.</span>

Answer:
f(x)=500+60x
So, B.
Step-by-step explanation:
Opening balance =500
Deposits= 60__ monthly
Write as a function
Represent the number of months with x and the balance at any month with f(x)
f(x) is calculated as thus:
Opening Balance + Deposits * Number of Months
So, we have:
f(x)=500+60*x
So, f(x) = 500+60x
