WILL MARK BRAINLEST Lillian lost her ELA book. Her school charges a lost book fee of 60 % of the cost of the book. Lillian received a notice stating she owed the school $45 for the lost book.
Which equation best represents the proportional relationship between the school’s cost for the book and the amount a student must pay for a lost book. Let c represent the school’s cost of the book in dollars and d represent the student’s cost in dollars
Question 4 options:
d = .60c
c = .60d
d = 45c
c = 45d
Answer:
The first one
Step-by-step explanation:
Answer:
D=.60c
Step-by-step explanation:
D is the amount that the student has to pay, and since they have to bay 60% of the amount, you'd take the amount times .6. So that leaves us with d=.60c. Hope this helps!

Answer:
Its D. On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 3) and goes through (1, 2).
Step-by-step explanation:
The graph of the function f(x) = 3^{(2/3)x} is an exponentially growing function.
What are some function transformations?Suppose we have a function f(x).
f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).
f(x ± c) = Horizontal left/right shift by c units (x - + c, y).
(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).
f(bx) = Horizontal compression b > 0, horizontal stretch for b < 0. (bx , y).
f(-x) = Reflection over the y-axis, (-x, y).
-f(x) = Reflection over x-axis, (x, -y).
The graph of the function f(x) = 3^{(2/3)x} is an exponentially growing function and has a y-intercept at (0, 1).
The function grows from the second quadrant to the first quadrant in an exponential manner as illustrated in the attached graph.

(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
(a + b) (a – b) = a2 – b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x – b) = x2 + (a – b)x – ab
(x – a)(x + b) = x2 + (b – a)x – ab
(x – a)(x – b) = x2 – (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3 = a3 – b3 – 3ab(a – b)
(x + y + z) 2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y – z) 2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
(x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
(x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
x2 + y2 = 1212 [(x + y)2 + (x – y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3 = (x + y) (x2 – xy + y2)
x3 – y3 = (x – y) (x2 + xy + y2)

Step-by-step explanation:
Both make a matter of 80%, the first one is because 4/5 in radical form is 80/100, The second answer is because 462 + 378 = 840, 840 simplified with 1,050 makes 4/5 = 80/100 or 80%

Use the converse of the Pythagorean theorem to decide whether ΔABC is a right triangle by answering the questions.
1. Use the Pythagorean theorem to find AD. Show your work.
2. Find AC. Show your work.
3. Is ΔABC a right triangle? Explain.
Answer:
1. Use the Pythagorean theorem to find AD. Show your work.
AD=9
Side BD=12, and side AB=15. We know that side AB is the hypotenuse, so AD^2+144=225
225-144=81, so side AD=9
2. Find AC. Show your work.
AC=25
To find AC, we can add AD and DC
9+16=25
3. Is ΔABC a right triangle? Explain.
ABC is a right triangle because AB^2+BC^2=AC^2

Click to show whether each equation represents a linear or nonlinear function.
Answer:
[tex]y = x^2 + 1[/tex] -- Nonlinear
[tex]y = x^1 + 2[/tex] -- Linear
[tex]y = x[/tex] --- Linear
[tex]y = 5(x + 2)[/tex] --- Linear
[tex]y = x(x)[/tex] --- Nonlinear
Step-by-step explanation:
Required
Categorize each function as linear or nonlinear
First, it should be noted that a linear function has the form [tex]y = mx + b[/tex].
So, the following question will be solved based on the above form
(a):
[tex]y = x^2 + 1[/tex]
This can not be expressed as [tex]y = mx + b[/tex]
Hence, it is a nonlinear function
(b):
[tex]y = x^1 + 2[/tex]
This can be further expressed as:
[tex]y = x + 2[/tex]
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(c):
[tex]y = x[/tex]
This can be further expressed as:
[tex]y = x + 0[/tex]
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(d):
[tex]y = 5(x + 2)[/tex]
This can be further expressed as:
[tex]y = 5x + 10[/tex] -- by opening the bracket
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(e):
[tex]y = x(x)[/tex]
This can be further expressed as:
[tex]y = x^2[/tex] --- by opening the bracket
This can not be expressed as [tex]y = mx + b[/tex]
Hence, it is a nonlinear function
