Answer:
Si la pendiente ([tex]m[/tex]) disminuye 3 unidades, entonces tenemos que [tex]y = -4[/tex].
Step-by-step explanation:
Sea la función lineal [tex]d(x) = 3\cdot x - 4[/tex], una función está definida por la siguiente expresión matemática:
[tex]y = m\cdot x + b[/tex] (1)
Donde:
[tex]x[/tex] - Variable independiente.
[tex]y[/tex] - Variable dependiente.
[tex]m[/tex] - Pendiente.
[tex]b[/tex] - Intercepto.
Por comparación directa, tenemos que [tex]y = d(x)[/tex], [tex]m = 3[/tex] y [tex]b = -4[/tex]. Si [tex]m[/tex] disminuye en 3 unidades, entonces tenemos la siguiente ecuación lineal:
[tex]y = -4[/tex]

Step-by-step explanation:
Grace, Maci, and Kendra all have a large collection of earrings.
The number of pairs of earrings in Grace’s collection is represented by x.
The number of pairs of earrings in Maci’s collection is three times the number of pairs in Grace’s collection.
Kendra has 4 earrings in her collection.
The total number of pairs of earrings in all three girls’ collections is 52.
How many pairs of earrings are in Maci’s collection?
Answer:
36
Step-by-step explanation:
Kendra has 4 so 52-4 (so it's out of the way) now you have 48
Divide 48 by 3 (leaves you 16). It can't be 16 because you have to add 16 and the sum of 16 x 3. So, go down a few numbers
12 + (12x3) = 48 plus Kendra's 4 is 52

1. The base of a rectangular prism has an area of 20 square inches. If the prism has an altitude of 8 inches, determine and state the volume of the prism, in cubic inches?
Answer:
160 in^3
Step-by-step explanation:
To find the volume, you do the base x height. If the base if 20 in^2 and the altitude is 8 in, then the volume is 20 * 8 in^3
20 * 8 = 160

Charlotte needs 16 1/2 yards of fabric to make a quilt. She has one piece of fabric that is 3 1/2 yards and another piece of fabric that is 6 3/4 yards. How many more yards of fabric does Charlotte need to make the quilt?
YOUR ANSWER BETTER NOT HAVE A LINK OR YOU ARENT GETTING POINTS!
Answer:
6 1/4
Step-by-step explanation:
Add up the fabric that she has
3 1/2 + 6 3/4
Get a common denominator
3 2/4 + 6 3/4
9 5/4
9 4/4 + 1/4
10 1/4
Subtract this from the fabric that she needs
16 1/2 - 10 1/4
Get a common denominator
16 2/4 - 10 1/4
6 1/4

An amusement park charges an entrance fee of $20 and the rides cost $4 each. Suppose you write a function for the total cost for entering the park and riding a. Number of the rides. What is the domain of the function based on the given context?
Answer:
With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:
C(x)=20+4x,where:
x is the number of rides
The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.
Nancy watches her dad fix a broken chair with a nail and a hammer, but she finds the hammering sound too loud. So, she decides to go back to her room, which is next door. On entering her room, she finds the hammering does not sound as loud. Why does the sound become faint?
Answer:
The sound of hammering becomes fainter as Nancy goes into her room because some of the sound waves are absorbed by the walls. Only part of the sound waves coming from the other room comes into her room, so the hammering sounds quieter.
I hope this helps. Good luck ^^

Find the perimeter of this shape please help I will award brainlisest
Answer:
22 cm
Step-by-step explanation:
Answer:
The shape is made up of a square and a rectangle.
So calculating the area of both the figures and then adding them would give us the required result.
Area of square = (a)² = (4)² = 16 sq unit.
Area of rectangle = l×b = 3×2 = 6 sq unit.
Now, the required area = 16 + 6 = 22 sq unit.

The table to the right shows the results of a survey taken
of what students wanted to have as their first car.
The options were sedan (4-door car), truck, SUV, coupe (2-door car), or other.
What are the odds that a student chose either a truck or an SUV?
A). 35/112
B) 29/56
C) 23/112
D) 31/56
Answer:
So we have either a truck or a SUV
so we need the probability of both
35+23/Total
so 35/112
Use a special right triangle to find the value of y. Write as a decimal rounded to the nearest 10th
Given:
The figure of a right angle triangle.
To find:
The value of y.
Solution:
in a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
In the given right triangle,
[tex]\sin 60^\circ=\dfrac{6}{y}[/tex]
[tex]\dfrac{\sqrt{3}}{2}=\dfrac{6}{y}[/tex]
On cross multiplication, we get
[tex]\sqrt{3}y=12[/tex]
[tex]y=\dfrac{12}{\sqrt{3}}[/tex]
[tex]y=\dfrac{12\sqrt{3}}{3}[/tex]
[tex]y=4\sqrt{3}[/tex]
Therefore, the value of y is [tex]4\sqrt{3}[/tex] units.

Answer:
x = 42,33°
Step-by-step explanation:
3x + 1° + 52° = 180° [angles on a straight line]
3x + 53° = 180°
3x = 180° - 53°
3x = 127°
divide both sides by 3
x = 42,33°

Please only answer if you can help!! Which statements describe the end behavior of f(x)?
Look at the pictures down below
Answer:
Step-by-step explanation:
Let’s start seeing what happens to the left. It stops before x = -1, but it continues to do down
so as x approaches -1, y approaches -oo
Now we have to see what happens to the right. In the case the graph doesn’t stop and it keeps to go up
so as x approaches oo, y approaches oo

A small theater had 6 rows of 23 chairs each. Workers just removed 9 of these chairs. How many chairs are left?
Answer:
