x - y = 4 and x + y = 9
Answer:
5-1=4 and 5+4=9
Step-by-step explanation:
[tex]\huge\red{ƛƝƧƜЄƦ}[/tex]
System of Linear Equations entered :
[1] x - y = 4
[2] x + y = 9
Graphic Representation of the Equations :
y + x = 4 y + x = 9
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 9
// Plug this in for variable y in equation [1]
[1] x - (-x +9) = 4
[1] 2x = 13
// Solve equation [1] for the variable x
[1] 2x = 13
[1] x = 13/2
// By now we know this much :
x = 13/2 y = -x+9
// Use the x value to solve for y
y = -(13/2)+9 = 5/2
Solution :
{x,y} = {13/2,5/2}
Hope it Helps ☺what value of x makes the question true? 2x + 9 = 4x - 1
Answer:
5
Step-by-step explanation:
2x +9 =4x - 1
2x - 4x =-1 - 9
-2x=-10 /(-1)
2x=10
x=10 :2

(b^5)^3 x b^4 simplify
Answer:
b^19
Step-by-step explanation:
In the first factor, we need to use a formula to simplify. The formula is x^a^b = x^(ab). So that means that our first factor simplifies to b^15. Then we add up the powers to simplify it even more. b^15 * b^4 = b^19 using another formula. Therefore b^19 is the answer.

Given M = the set of counting numbers and N = the set of even numbers, find M - N.
need answer
Answer:
M-N = set of odd numbers
M-N = 1,3,5,7,9,11,.....................................so on it till infinity
Step-by-step explanation:
M = the set of counting numbers
set of counting number are are all the numbers which is used for counting.
They are also called Natural numbers
In numerical form set of counting numbers can be represented as
M = the set of counting numbers = 1,2,3,4,5,6,7,8,9..............................till infinity
N = the set of even numbers
set of even numbers all the counting numbers which are multiple of two
In numerical form set of counting numbers can be represented as
N = the set of even numbers = 2,4,6,8,10,12................so on till infinity
__________________________________
now we have to find M-N
it means from set of counting number, all the even numbers would be excluded
IN such case
If we exclude all the even numbers, then only odd numbers will remain.
M-N will be = 1,3,5,7,9,11,.....................................so on it till infinity
If we look it closely , the given set is set of odd numbers
odd numbers are counting numbers in form of 2n+1 where n = 0,1,2,3....
Thus,
M-N can also be said as set of odd numbers
M-N = set of odd numbers
M-N = 1,3,5,7,9,11,.....................................so on it till infinity
4 cachorros se terminan un paquete de croquetas en 6 días, si tuviéramos 3 cachorros ¿cuantos días duraría el paquete ?
Answer:
4 1/2 días.
Step-by-step explanation:
En la pregunta se nos dice que:
4 cachorros terminarán un paquete de croquetas en 6 días, si tuviéramos 3 cachorros, ¿cuántos días duraría el paquete?
4 cachorros = 6 días
3 cachorros = y días
Cruz multiplicar
4 cachorros × y = 3 cachorros × 6 días
y = 3 cachorros × 6 días / 4 cachorros
y = 18/4
y = 4 2/4
y = 4 1/2 días
Por lo tanto, el paquete de croquetas para 3 cachorros tendrá una duración de 4 1/2 días.

y = 4x - 3orf(x) = 4x - 3(15 / 5)+9+(14 - 5 )*3
Answer:
39
Step-by-step explanation:
(15 / 5)+9+(14 - 5 )*3
Answer: 39
Step-by-step explanation:
I started with simplifying 15/5 to 3
3+9+(14 - 5)*3
Than Simplified (14 - 5) to 9
3+9+9*3
Next, I did 9*3 due to PEMDAS
3+9+27
Finally, I added it all together to get 39

9 = -7w + 12w – 6
Solve steps explaining pls
Answer:
Step-by-step explanation:
9 = - 7w + 12w - 6
by transposing,
9 + 6 = -7w + 12w
15 = 5w
w = 15 / 5
w = 3
Hope this helps
plz mark as brainliest!!!!!!
Answer:
[tex]w=3[/tex]
Step-by-step explanation:
[tex]9 = -7w + 12w -6[/tex]
Start by combining like terms ([tex]-7w+12w[/tex]):
[tex]9=5w-6[/tex]
Add [tex]6[/tex] to both sides of the equation:
[tex]15=5w[/tex]
Divide both sides of the equation by the coefficient of [tex]w[/tex], which is [tex]5[/tex]:
[tex]3=w[/tex]
_
Check your work by substituting the solved value of [tex]w[/tex] ([tex]3[/tex]), into the initial equation:
[tex]9 = -7(3) + 12(3) -6[/tex]
Multiply:
[tex]9=-21+36-6[/tex]
Combine like terms:
[tex]9=9[/tex]
Since both sides of the equation are equal, our answer is correct!
Clarissa sells handmade bracelets for each. The graph below shows her profits after expenses.
What does the point represent?
An electrician charges a base fee of $70 plus $45 for each hour of work. The minimum the electrician charges is $160. Create a table that shows the amount the electrician charges for 1, 2, 3, and 4 hours of work. Determine the domain and range of the relation in context and explain whether or not this represents a function.
Answer:
1) See below for table.
2) Domain: [tex]\{1, 2, 3, 4\}[/tex]
Range: [tex]\{160, 160, 205, 250\}[/tex]
Yes, this is a function.
Step-by-step explanation:
We know that the electrician charges a base fee of $70 plus $45 for each hour of work.
We also know that the minimum the electrician charges is $160.
Let's write an equation. Let x denote the number of hours worked and y denote the total price. There's also a base fee of $70. So, we can write the following equation:
[tex]y=45x+75[/tex]
Part 1)
Let's create our table for 1, 2, 3, and 4 hours. To do so, we simply need to substitute each value for x in our equation.
1 Hour:
We have:
[tex]y_1=45(1)+70[/tex]
Multiply and add:
[tex]y_1=45+70=\$115[/tex]
However, notice that the minimum the electrician charges is $160. Therefore, for one hour of work, the electrician will still charge $160. So:
[tex]y_1=\$160[/tex]
2 Hours:
Substitute 2 for x:
[tex]y_2=45(2)+70=90+70=\$160\\[/tex]
So:
[tex]y_2=\$160[/tex]
3 Hours:
Substitute 3 for x:
[tex]y_3=45(3)+70=135+70=\$205[/tex]
So:
[tex]y_3=\$205[/tex]
4 Hours:
Substitute 4 for x:
[tex]y_4=45(4)+70=180+70=\$250[/tex]
So:
[tex]y_4=\$ 250[/tex]
Therefore, for 1, 2, 3, and 4 hours of work, the prices will be $160, $160, $205, and $250, respectively.
We can create the following table (please scroll down to see the table. Also, y is measured in dollars).
Part 2)
The domain of a relation are the input values.
In this context, our input values are the amount of hours worked, and we calculated for 1, 2, 3, and 4 hours of work.
Therefore, our domain in this context is:
[tex]\{1, 2, 3, 4\}[/tex]
The range of a relation are the output values.
In this context, the output values are the price for x hours of work.
Therefore, our range in this context is:
[tex]\{160, 160, 205, 250\}[/tex]
This relation does represent a function. Remember that a function cannot have repeating input values. In other words, no one input can be equal to two or more different outputs. However, one output can be mapped to two or more different inputs.
For our table, none of the inputs are repeating. So, our relation is a function.
And we're done!
