Answer:
76
Step-by-step explanation:
Plug 4 in for each x
Answer:
76
Step-by-step explanation:
given f(x)=x^3+x^2-x what is f(4)
whenever u see f(4) it is telling you that whenever you see an x you would replace it with a 4 so you start substituting the x for 4's or replacing them (same thing XD) 4^3+4^2-4 4 times 4 times 4 = 64 + 4 times 4 = 16
64 + 16 - 4 = 76

Mr. Percuoco is working the fish bowl toss. He used 13.6 gallons of water to fill 40 fish bowls. If he put an equal amount of water in each one, how many gallons of water are in each fish bowl?
Answer:
0.34 gallons of water
Step-by-step explanation:
Mr Percuoco is working the fish bowl toss
He used 13.6 gallons of water to fill 40 fish bowls
Therefore the gallons of water in each fish bowl can be calculated as follows
= 13.6/40
= 0.34
Hence there are 0.34 gallons of water in each fish bowl
Solve the simultaneous equations:
y−2x=12
y+2x=4
x=
and y=
Answer:
y = 8
x = -2
Step-by-step explanation:
(If you are cancelling the y form the equation to find x first then subtract the equation as the signs are the same or else if you are cancelling the x first then add the equations as the signs are different)
y-12x=12 l cancelled the x from the equation to
y+2x=4 find y

Answer:
Wheres the picture?
Step-by-step explanation:
Use Simplex Method and Maximize 2x+3y =z
Hello!
Solve for x.
2x+3y=z
Step 1: Add -3y to both sides.
2x+3y+−3y=z+−3y
2x=−3y+z
Step 2: Divide both sides by 2.
2x/2=−3y+z/2
Answer:x= −3/2y+1/2zThank you for asking this question!
It would be greatly appreciated if you thanked me and marked me as the brainliest!

What is √7/√11 in simplest radical form?
Answer:
[tex]\sqrt{77}[/tex]
Step-by-step explanation:
[tex]\sqrt{7} \sqrt{11}[/tex]
Apply radical rule: [tex]\sqrt{a} \sqrt{b} =\sqrt{a*b}[/tex]
[tex]\sqrt{7}\sqrt{11} =\sqrt{7*11}[/tex]
[tex]=\sqrt{7*11}[/tex]
Multiply the numbers: [tex]7*11=77[/tex]

The teacher does not have to spend all $36. Write an inequality relating 36 and 9 (7 - x) representing this situation. (Copy/paste as needed: ≤ ﹤ ≥ ﹥)
Answer:
9(7-x) < 36Step-by-step explanation:
From the question, we are to relate the amount the teacher spent to the expression 9(7-x).
Since the teacher does not have to spend all the $36, this means that he spent amount less than $36 but not equal to $36. Hence the best inequality sign that relates both expression is a less than sign (<) as shown;
9(7-x) < 36
hence the required inequality is 9(7-x) < 36
Evaluate : 2a^2+3b^3-10
For a=2 and b=(-2)
Step-by-step explanation:
Just substitute the values of a and b
2a^2 + 3b^3 - 10
2x2^2 + 3 x (-2)^3 - 10
= 2 x 4 + 3 x (-8) - 10
= 8 - 24 - 10
= 8 - 34
= -26
Answer:
- 26
Step-by-step explanation:
Given
2a² + 3b³ - 10 ← substitute a = 2, b = - 2 into the expression
= 2(2)² + 3(- 2)³ - 10
= 2(4) + 3(- 8) - 10
= 8 - 24 - 10
= - 16 - 10
= - 26

You are offered a job as a sales professional. You are offered a monthly base (fixed) salary of $1,000 plus 30% of the total sales you make for the month.
1) Write a linear function that represents your monthly income.
2) What is the slope? What does it mean in this context?
3) What is the y-intercept? What does it mean in this context?
4) BONUS (1 pt) If you sell $5,000 worth of product, what is your monthly income?
Answer:
1) y = 0.3x + 1000
2) slope = 0.3
The slope is the fraction of the monthly sales that is added to your salary.
3) y-intercept = 1000
The y-intercept is the fixed part of the salary, $1000.
4) The salary is $2500
Step-by-step explanation:
1)
monthly salary = fixed part + variable part
The fixed part is $1000. Every month you receive $1000 no matter the amount of sales.
The variable part varies according to the amount of sales. You get 30% of the of the monthly sales. Let the monthly sales be x. The variable part is 0.3x
Let the monthly salary = y.
y = 1000 + 0.3x
y = 0.3x + 1000
2)
slope = 0.3
The slope is the fraction of the monthly sales that is added to your salary.
3)
y-intercept = 1000
The y-intercept is the fixed part of the salary, $1000.
4)
In this case, x = 5000
y = 0.3x + 1000
y = 0.3(5000) + 1000
y = 1500 + 1000
y = 2500
The salary is $2500.

Show that the equation x^3+4x=6 has a solution between 1.1 and 1.2
plz I need help my dudes I have no clue what I’m doing
Answer:
see explanation
Step-by-step explanation:
If there is a solution between x = 1.1 and x = 1.2 then there will be a change in sign when the equation is evaluated at the points, indicating the graph has crossed the x- axis, where the solution lies.
Given
x³ + 4x = 6 ( subtract 6 from both sides )
x³ + 4x - 6 = 0 ← in standard form
Evaluating for x = 1.1
(1.1)³ + 4(1.1) - 6
= 1.331 + 4.4 - 6 = - 0.269 ← < 0
Evaluating for x = 1.2
(1.2)³ + 4(1.2) - 6
= 1.728 + 4.8 - 6 = 0.528 ← > 0
Since there is a change in sign the graph has crossed the x-axis from below / indicating a solution between x = 1.1 and x = 1.2
-18=7v+9-10v
slove for v.
Answer:
v=9
Step-by-step explanation:
-18 = 7v + 9 - 10v
combine like terms
-18 = -3v + 9
-9 -9
-27 = -3v
divide both sides by -3
9 = v
or
v = 9

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Equality Properties
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
[Standard Form] -5x - 4y = -12
Step 2: Rewrite
Add 5x to both sides: -4y = 5x - 12Divide -4 on both sides: y = -5/4x + 3Step 3: Identify
Break apart the function.
