Answer:
All real numbers -----> X=0
Step-by-step explanation:
1) 3x + 6 = 3(2 + x) Distribute the 3 on the right side
2) 3x + 6 = 6 + 3x Subtract 3x from both sides
3) 6=6 Subtract 6 from each side
4) 0=0
5) All real numbers

Which equation represents the graphed function?
O y=-2x + 3
O y = 2x + 3
O y = 1/2x+3
O y=-1/2x+3
The equation of the function is y = -2x + 3. The correct option is (A).
How to represent a straight line on a graph?To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.
The graph of the given function show points (0, 3) and (1, 1) on it.
In order to find the equation for the line use slope-point method as follows,
The slope of the line is given as below,
Slope = (3 - 1)/(0 - 1)
= -2
Now, the equation can be written as,
(y - 3)/(x - 0) = -2
=> y - 3 = -2x
=> y = -2x + 3
Hence, the equation of the function shown in the graph is y = -2x + 3.

18.You've just placed an order for a set of tools for a new employee. The cost of the tools is $185.95. If you must pay 4% sales tax on the purchase, how much will you pay for the tools? (Round your answer to two decimal places. Note: This question requires two calculations.)
Answer:
Amount pay for tool = $193.39 (Approx)
Step-by-step explanation:
Given:
Cost of the tools = $185.95
Sales tax = 4%
Find:
Amount pay for tool
Computation:
Amount pay for tool = Cost of the tools[1+Sales tax]
Amount pay for tool = $185.95[1+4%]
Amount pay for tool = $193.39 (Approx)
A brownie recipe called for 1 2/3 cups of sugar. If you are making 1 1/2 times the recipe, how much more sugar will you need?
Please put the answer in a fraction.
Please don't reply if you dont know the answer.
Answer:
2 1/2 cups of sugar
Step-by-step explanation:
Make a equation to cross multiply and get answer
x is the unknown amount
1 recipe = 1 2/3 sugar
1 1/2 recipe = x sugar
now cross multiply
x = 1 2/3 * 1 1/2
x = 2 1/2
The amount of sugar needed will be 2¹/₂ cups of sugar.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Make an equation to cross multiply and get an answer
x is the unknown amount
1 recipe = 1²/₃ sugar
1 1/2 recipe = x sugar
Now cross multiply
x = 1²/₃ x 1¹/₂
x = 2¹/₂
Therefore, the amount of sugar needed will be 2¹/₂ cups of sugar.

Let the total no. of employees be x
From the information we get that,
30% of x= 120
Hence, 30/100x=120
x=120×100/30

What single decimal multiplier would you use to decrease by 3% followed by a 3% decrease?
A 3% decrease means you still have 100% - 3% = 97% left
The multiplier here would be 0.97
If you do another 3% decrease, you will use another multiplier of 0.97
Multiply 0.97*0.97 to get 0.9409
So this is a 1-0.9409 = 0.0591 = 5.91% decrease overall

B.) When you divide 32.4 by 102, the decimal moves two places to the left.
C.) When you multiply 0.32 x 102, the decimal moves 2 places to the right.
D.) When you multiply 3.24 by 102, the answer is 3,240.
E.) When you divide 324 by 102, the answer is 3.24.
A=f
b=t
c=t
d=f
e=f
this should be correct. :)
Answer:
B, C
Step-by-step explanation:
A.) When you multiply 32.4 x 103, the decimal moves 3 places to the right.
[tex]32.4 \cdot 103 = 3337.2[/tex]
No, it is 2 places to the right.
B.) When you divide 32.4 by 102, the decimal moves two places to the left.
[tex]$\frac{32.4}{102} \approx 0.32$[/tex]
Yes. If we consider 32.4 and 0.32.
[tex]32.4 = 0.324 \cdot 10^2[/tex]
We obtain 0.32 by moving the number 32 decimal two places to the left
C.) When you multiply 0.32 x 102, the decimal moves 2 places to the right.
[tex]0.32 \cdot 102 = 32.64[/tex]
Yes
D.) When you multiply 3.24 by 102, the answer is 3,240.

Una compañía de danza de 156 bailarines hace una coreografía formando filas y columnas.Si en una fila hay 20 bailarines más que en una columna ¿cuántas filas y cuantas columnas son?
Responder:
Por favor, consulte la explicación.
Explicación paso a paso:
Dado lo siguiente:
Número de bailarines = 156
Sea número de bailarines en una columna = c
Número de bailarines seguidos = c + 20
Multiplicar el número de bailarines en fila y columna dará el número total de bailarines.
Por lo tanto,
c * (c + 20) = 156
c² + 20c = 156
c² + 20c - 156 = 0
c² + 26c - 6c - 156 = 0
c (c + 26) - 6 (c + 26) = 0
(c + 26) = 0 o (c - 6) = 0
c = - 26 o c = 6
C no puede ser negativo
Por lo tanto,
Número de bailarines en columna = 6
Número de bailarines en fila = 20 + 6 = 26

Answer:
x < 727 pounds
Step-by-step explanation:
Let the weights of every other alligator caught in Mississippi be represented with the variable [tex]x[/tex]
For the largest alligator ever caught to weigh 727 pounds, that means that the weights of every other alligator caught in Mississippi will definitely be less than 727 pounds.

Evaluate the following.
10-2-3+4x4
Answer:
Step-by-step explanation:
10-2= 8 -3 = 5 +4 =9 *4 =36
Answer:
21
Step-by-step explanation:
Did you mean "4 times 4?" or '4x^4?"
I will assume you meant the first interpretation.
Order of operations rules require that we do multiplication before addition and subtraction. Thus, multiplying 4 by 4, we get:
10 - 2 - 3 + 16
which simplifies to 21
Note: Please use " * " to indicate multiplication: 4*4 = 16, or 4·4 = 16.
