Answer:
9x-11
Step-by-step explanation:
-5+2(x-3)+7x
Distribute
-5 +2x -6 +7x
-11 +9x
9x-11
[0, inf)
The least y-value the function can have is 0 because the square of a number cannot be negative.
Answer:
f^-1 represents the number of hours the bacteria developed
Step-by-step explanation:
To find inverse of a function , replace f(t) with y
replace t with y and y with x
solve for y
divide both sides by 100
take ln on both sides
divide both sides by ln
multiply by 3 on both sides
Replace x with t and y with f^-1
f^-1 represents the number of hours the bacteria developed
You can be going the speed limit, 20 mph, or you can be going 20 mph under the speed limit. Which would mean you'd be stationary or not moving.
Hey, It looks like you're in Algebra and I'm here to give the best solution I can!
To write the equation, you are going to use the Standard Form. Standard Form is one way of solving this problem, and it is used to find the x,and y-intercepts of a problem.
Standard Form can be written using the equation <span>ax+by=c
</span>In your problem, you will write the equation like so, with 'x' representing T-Shirts, and 'y' representing pants:
<span>
8x+5y=220</span>
Now, in order to find the x-intercept you need to substitute a 0 for the 'y' variable and solve the new equation, 8x=220.
I'm sure you know you need to divide both sides by 8 which will give you the answer x=27.5.
Now, in order to find 'y' you would substitute a 0 for the 'x' variable which will give you an equation that should look like 5y=220.
Then, divided both sides by 5 to get your y-intercept.
y=44
Finally,you know that each T-Shirt (x) is $27.50, and each pair of pants(y)costs $44
-I hope this helped you, Sincerely, Auhrevo!
