daniel spent half of his paycheck on video games. to earn more money, he did chores at home and received $20. how much was his paycheck if he ended up with $56
Answer: His paycheck was $72.
Step-by-step explanation:
Let x = paycheck amount.
Given, Amount spent on video games = [tex]\dfrac x2[/tex]
Amount he has left of it = [tex]x-\dfrac x 2=\dfrac x 2[/tex]
Amount received = $20
Total amount amount he has left = [tex]\dfrac x 2 +20[/tex]
According to the question,
[tex]\dfrac x 2 +20 = 56\\\\\Rightarrow\ \dfrac x 2= 36\\\\\Rightarrow\ x= 2\times 36=72[/tex]
∴ His paycheck was $72.
Which line has the greatest rate of change?
A. The line passing through (0, 2) and (4, 10)
B. The line passing through (0,5) and (2,8)
C. The line passing through (0,0) and (3,-4)
D. The line passing through (0,6) and (12,9)
Answer:
I thought it was the last one but I mean if it was wrong sorry
Greetings from Brasil....
The rate of change between 2 points is obtained through the expression:
m = ΔY/ΔXm = (Y₂ - Y₁)/(X₂ - X₁)a) (0, 2) and (4, 10) so, X₁ = 0; X₂ = 4; Y₁ = 2 and Y₂ = 10
m = ΔY/ΔX
m = (Y₂ - Y₁)/(X₂ - X₁)
m = (10 - 2)/(4 - 0)
m = 8/4 = 2
b) (0,5) and (2,8) so, X₁ = 0; X₂ = 2; Y₁ = 5 and Y₂ = 8
m = ΔY/ΔX
m = (Y₂ - Y₁)/(X₂ - X₁)
m = (8 - 5)/(2 - 0)
m = 3/2
c) (0,0) and (3,-4) so, X₁ = 0; X₂ = 3; Y₁ = 0 and Y₂ = - 4
m = ΔY/ΔX
m = (Y₂ - Y₁)/(X₂ - X₁)
m = (- 4 - 0)/(3 - 0)
m = -4/3
d) (0,6) and (12,9) so, X₁ = 0; X₂ = 12; Y₁ = 6 and Y₂ = 9
m = ΔY/ΔX
m = (Y₂ - Y₁)/(X₂ - X₁)
m = (9 - 6)/(12 - 0)
m = 3/12 ⇔ m = 1/4
Among all the values above, the largest is 2, so points
(0; 2) and (4; 10)

Answer:
This is the answer
Step-by-step explanation:
Solving 3x2-9x-5 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 3
B = -9
C = -5
Accordingly, B2 - 4AC =
81 - (-60) =
141
Applying the quadratic formula :
9 ± √ 141
x = —————
6
√ 141 , rounded to 4 decimal digits, is 11.8743
So now we are looking at:
x = ( 9 ± 11.874 ) / 6
Two real solutions:
x =(9+√141)/6=3/2+1/6√ 141 = 3.479
or:
x =(9-√141)/6=3/2-1/6√ 141 = -0.479
Two solutions were found :
x =(9-√141)/6=3/2-1/6√ 141 = -0.479
x =(9+√141)/6=3/2+1/6√ 141 = 3.479
Solve the system of equations below.
Answer:
B
Step-by-step explanation:
So we have the system of equations:
[tex]x-2y=3\\2x-3y=9[/tex]
To solve, we can use the substitution method. First, add 2y to both sides in the first equation:
[tex]x=3+2y[/tex]
Now, substitute this into the secon equation:
[tex]2(3+2y)-3y=9[/tex]
Distribute the 2:
[tex]6+4y-3y=9[/tex]
Combine like terms:
[tex]6+y=9[/tex]
Subtract 6 from both sides:
[tex]y=3[/tex]
So, the value of y is 3.
Substitute this back into the original equation to find x. Thus:
[tex]x=3+2(3)[/tex]
Multiply:
[tex]x=3+6[/tex]
Add:
[tex]x=9[/tex]
So, our answer is (9,3)

Studio fee:$8 per hour
Vase:$10
Answer:
x = hours spent8x+10 = 464.5 hoursStep-by-step explanation:
We are asked for the number of hours spent at the studio, so it is reasonable to let the variable x stand for the number of hours.
The total cost is ...
vase cost + hourly cost = total cost
where hourly cost = (# of hours)(cost per hour)
10 + 8x = 46
8x = 36 . . . . . . subtract 10
x = 4.5 . . . . . . . divide by 8
4.5 hours were spent at the studio.
14. A manufacturer of lighting fixtures has daily production costs of C = 120 − 5x + 0.25x 2 , where C is the total cost (in dollars) and x is the number of units produced. How many fixtures should be produced each day to yield a minimum cost? What is that minimum cost?
Answer:
Value of x = 10
Minimum cost (C) = 45
Step-by-step explanation:
Given:
Equation:
120 - 5x + 0.25x²
Find:
Value of x
Minimum cost
Computation:
0.25x² - 5x + 120
x = -[b/2a]
x = -[(-5)/2(0.25)]
x = 10
Value of x = 10
Minimum cost (C) = 120 - 5x + 0.25x²
Minimum cost (C) = 120 - 5(10) + 0.25(10)²
Minimum cost (C) = 45

Use the diagram shown. Solve for x. Find the angle measures to check your work.
mZAOB = (9x - 5)º
mZBOC = (2x +11°
mZCOD = (6x + 10°
X=
Answer:
x = 5
Step-by-step explanation:
From the picture attached,
It's given that ∠AOB ≅ ∠COD
therefore, m∠AOB = m∠COD
Now from the given measures of the equal angles,
9x - 5 = 6x + 10
9x - 6x - 5 = 10
3x - 5 = 10
3x = 10 + 5
3x = 15
x = [tex]\frac{15}{3}[/tex]
x = 5
Therefore, measure of the angles given in the picture will be,
m∠AOB = (9x - 5)° = 40°
m∠BOC = (2x + 11)° = 21°
m∠COD = (6x + 10)° = 40°

Step-by-step explanation:
f(x) = 25 / (10x -20)
When 10x - 20 = 0, f(x) is undefined. Therefore x = 2 is not in the domain for f(x) to be a function.

all real numbers greater than or equal to 0
all real numbers greater than or equal to -2
all real numbers greater than or equal to -3
Answer:
Option (4)
Step-by-step explanation:
Domain:
Domain of function is defined by the x-values (Input values) on the graph.
Range:
Range of a function is defined by the y-values (output values) on the graph.
From the graph attached,
x-values are starting from (-3) to infinity.
Therefore, domain of the function will be all real numbers greater than equal to (-3).

I need help graphing this
=======================================================
Explanation:
The given equation y = (-2/3)x+1 is in the form y = mx+b
m = -2/3 is our slope
b = 1 is the y intercept
The y intercept is where the line crosses the vertical y axis. Because b = 1, this location is (0,1). So that's one point we can use to graph this equation.
Another point can be found using the slope
Recall that slope = rise/run
Since slope = -2/3, this means rise/run = -2/3 leading to rise = -2 and run = 3. The "rise = -2" portion tells us to go down 2 and then "run = 3" portion means we go to the right 3 units.
The "down 2, right 3" motion has us go from (0,1) to (3,-1). So (3,-1) is another point we can use. We only need two points to graph a straight line.
The diagram below provides a visual summary. It shows plotting point A as the y intercept, and then you move to point B using the "down 2, right 3" movement rule.
