Answer: The break-even point is x = 15
Step-by-step explanation:
We have the equations:
c(x) = 10*x
r(x) = 210 - 4*x
I suppose that c(x) is the cost equation, and r(x) is the revenue equation.
"break-even" means that you don't lose nor win anything, then the difference between the revenue and the cost is 0.
Then we need to solve:
r(x) - c(x) = 0
(210 - 4*x) - (10*x) = 0
210 - 4*x - 10*x = 0
210 - 14*x = 0
210 = 14*x
210/14 = x
15
This means that for x = 15, you break even.
what is x + y = -9 in y=mx+b form
Answer: Talk the Talk. Once a linear equation is solved for y, it is in slope-intercept form, y = mx + b. The coefficient of the x term, m, is the slope of the line and the number (or constant), b, is the y-intercept.

What is the slope between (2,1); (5,9)
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Answer:
[tex]\frac{8}{3}[/tex]
Step-by-step explanation:
(2, 1)
(5, 9)
Find the slope
____________
When finding slope, we always have to follow the formula :
[tex]\frac{y^2-y^1}{x^2-x^1}[/tex]
The y in the fraction are the second number within the coordinate points, while the exponents are the second number from the second point and the first number from the first point. The same goes for x. Therefore substitute x and y with their corresponding values :
[tex]\frac{9-1}{5-2}[/tex]
[tex]\frac{8}{3}[/tex]

A cylindrical pet carrier has a radius of 2 feet. If the height of the carrier is 1.7 feet, find the volume of the pet carrier. Round your answer to two decimal places. (use pi= 3.14)
Answer: [tex]31.352\ ft^3[/tex]
Step-by-step explanation:
Given
the radius of cylinder r=2 ft
height h=1.7 ft
The volume of a cylinder is given by
[tex]\Rightarrow V=\pi r^2h[/tex]
Putting values
[tex]\Rightarrow V=\pi \times 2^2\times 1.7\\\Rightarrow V=3.14\times 4\times 1.7=21.352\ ft^3[/tex]

What is the slope of the line y = 3x + 5?
Answer:
3
Step-by-step explanation:
The equation you gave is already in slope-intercept form. If you don't know what that is just search it up, but the general form for slope-intercept equations are y=mx+b, where y and x are pretty much self-explanatory, m is the slope, and b is the y-intercept. You want the slope, so in this equation, 3 would be the slope.

3

an employee at an arcade determined he could use the equation y=50-2x to predict the number of tokens a guest has,y, based on the number of minutes, x, the guest has been at the arcade. what is the meaning of the slope of the equation.
Answer:
The rate at which how many tokens a person loses per minute.
Step-by-step explanation:
If we move around the terms in the equation to fit standard form, it will be easier to determine the slope.
y = 50 - 2x
y = -2x + 50
We know that the slope is the coefficient of the x variable, so m = -2 or [tex]\frac{-2}{1}[/tex].
Since the slope is negative, we know that the line will go down as x increases. Since the slope is multiplied by the number of minutes x, we know that the slope represents the typical rate at which a guest spends tokens per minute. In simpler words, how many tokens a person loses every minute.
