Answer: y = -2/3x + 5
Step-by-step explanation: you find the slope by finding “rise/run”. the rise is -2, and the run is 3, so the slope is -2/3. the y intercept is 5

Step-by-step explanation:
3. Problem 2: Suppose a radio manufacturer has the total cost function C (x) = 43x + $ 1850 and the revenue function R (x) = $ 80x. Where "x" is the number of radios manufactured and sold. Find:
plissssssssssssss helpppp
Given that,
Total cost function, C (x) = 43x + $1850
The revenue function R (x) = $80x
To find,
The number of units that must be produced and sold to break even.
Solution,
At break even, cost = revenue
43x + $1850 = $80x
Subtract 80x from both sides.
43x + 1850 -80x = $80x -80x
1850 = 80x-43x
37x = 1850
x = 50
So, the required number of units are 50.

Write an equation for the statement. Then, solve the equation:
The volume of a can varies jointly as the height of the can and the square of its radius. A can with an 8 inch
height and 4 inch radius has a volume of 402.12 inches cubed. What is the volume of a can that has a 2 inch
radius and a 10 inch height?
PLZZ help
Answer:
V = 125.6 in³
Step-by-step explanation:
let V be volume, h the height and r the radius, then the equation relating the quantities is
V = khr² ← k is the constant of variation
To find k use the condition V = 402.12, h = 8, r = 4
402.12 = k × 8 × 4² = 128k ( divide both sides by 128 )
3.14 = k [ note 3.14 is π )
V = 3.14hr² ← equation of variation [ V = πr²h ]
Given r = 2 and h = 10, then
V = 3.14 × 10 × 2² = 3.14 × 40 = 125.6

i’ll make u brainliest if u answer
Answer:
The solution set is (5,6).
Step-by-step explanation:
Given equations are:
-6x + 6y= 6 Eqn 1
-6x + 3y=-12 Eqn 2
Subtracting Eqn 2 from Eqn 1
(-6x+6y)-(-6x+3y)= 6-(-12)
-6x+6y+6x-3y=6+12
3y = 18
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{18}{3}\\y=6[/tex]
Putting y=6 in Eqn 1
-6x+6(6)=6
-6x+36=6
-6x=6-36
-6x=-30
[tex]\frac{-6x}{-6}=\frac{-30}{-6}\\x=5[/tex]
Hence,
The solution set is (5,6).

A store owner buys cell phones for $40 and marks up the price by 25%. What is the sale price of a phone?
Answer:
$50
Step-by-step explanation:
Price of the cell phone bought p = $40
% of markup in price = 25%
Selling price of the cell phone = p + (%)p
Selling price of the cell phone = P + (0.25)p
Selling price of the cell phone = p + 0.25p
Selling price of the cell phone = 1.25p
Selling price of the cell phone = 1.25 * $40
Selling price of the cell phone = $50

Answer:
(x³+2x²)/3 cm³Step-by-step explanation:
Find the diagram attached
Volume of a pyramid = 1/3 * Base area * height
Base area = x*x
Base area = x²
Height = x+ 2
Get the volume:
Volume of the pyramid = 1/3 * x² * x+2
Volume of the pyramid = x²(x+2)/3
Volume of the pyramid = (x³+2x²)/3 cm³

7 + 9.3x = 23
9.3x = 23 - 7 [ 7 becomes -7 when transferred to RHS]
9.3x = 16
x = 16 /9.3 [ 9.3 becomes 1/9.3 when transferred to RHS]

in one year dog's weigh from 64 pounds to 80 pounds . by what percentage did the dog's weght increase
Answer:
15%
Step-by-step explanation:
First, let's find how many pounds the dog's weight increased by during the year.
80 - 64 = 16
Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).
[tex]\frac{16}{64}[/tex] • 100 = 0.25 • 100 = 25%

(19x19)-(17x17)=72
square root of 72
Solving Quadratic Equations using the Square Root Property
[tex]x^2+7x+10=0[/tex]
but the teacher's guide says the answer is 17i
Answer:
[tex] x = -2 [/tex] or [tex] x = -5 [/tex]
Step-by-step explanation:
You need to complete the square before you can take the square root of both sides.
[tex] x^2 + 7x + 10 = 0 [/tex]
Subtract 10 from both sides.
[tex] x^2 + 7x = -10 [/tex]
To complete the square, you need to add the square of half of the x-term coefficient to both sides.
The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.
[tex] x^2 + 7x + \dfrac{49}{4} = -10 + \dfrac{49}{4} [/tex]
[tex] (x + \dfrac{7}{2})^2 = -\dfrac{40}{4} + \dfrac{49}{4} [/tex]
[tex] (x + \dfrac{7}{2})^2 = \dfrac{9}{4} [/tex]
Now we use the square root property, if
[tex] x^2 = k [/tex], then
[tex] x = \pm \sqrt{k} [/tex]
[tex] x + \dfrac{7}{2} = \pm \sqrt{\dfrac{9}{4}} [/tex]
[tex] x + \dfrac{7}{2} = \pm \dfrac{3}{2} [/tex]
[tex] x + \dfrac{7}{2} = \dfrac{3}{2} [/tex] or [tex] x + \dfrac{7}{2} = -\dfrac{3}{2} [/tex]
[tex] x = -\dfrac{4}{2} [/tex] or [tex] x = -\dfrac{10}{2} [/tex]
[tex] x = -2 [/tex] or [tex] x = -5 [/tex]

I = $60, P = $750, r = 4%, t = ?. Find the amount of time
Answer:
The time required to accumulate simple interest of $ 60.00
from a principal of $ 750.00 at an interest rate of 4% per year is 2 years.
Step-by-step explanation:
Given
Interest I = $60Principle P = $750Interest rate r = 4% = 0.04To determine
Time period t = ?
Using the formula
I = Prt
t = I / Pr
substitute I = $60, P = $750 and r = 0.04 in the equation
t = 60 / ( 750 × 0.04 )
t = 2 years
Therefore, the time required to accumulate simple interest of $ 60.00
from a principal of $ 750.00 at an interest rate of 4% per year is 2 years.
