Answer:
y = 3x
Step-by-step explanation:
you can use the equation to determine how many miles the whale swims in any desired hour
example, if you want to know how far it swims in 5 1/2 hours then just plug 5 1/2 in for 'x' and solve for 'y'
y = 3(5.5)
y = 16.5
whale travels 16.5 miles when going at a rate of 3 mph

What is the y-intercept of f'(x)?

4
Answer:
A. -16
Step-by-step explanation:
Note that [tex]f^{-1}(x)[/tex] stands for the inverse of [tex]f(x)[/tex]. We can write the graph as [tex]y=\frac{3}{4}x+12[/tex]. Switching [tex]y[/tex] with [tex]x[/tex] and vice versa will now get us the inverse of the graph, so we see that the inverse is [tex]x=\frac{3}{4}y+12[/tex].
We are asked for the y-intercept, which is the point for which [tex]x=0[/tex]. Substituting that gives [tex]0=\frac{3}{4}y + 12[/tex] or [tex]\frac{3}{4}y = -12[/tex], so [tex]y=-12\cdot \frac{4}{3} = -16.[/tex] We are now done.

Your building plan for your restaurant includes one men's and women's restroom. The city inspector lets you kno that you must have at least 400 square feet per bathroom. If your building is a total 4,000 square feet, how many square feet are left for the development other nonbathroom areas?
Answer: 3200 ft^2
Step-by-step explanation:
You have a total area of 4,000 ft^2.
In your plan, you will make two bathrooms (one men's restroom and one women's restroom)
We know that each one of them needs 400ft^2, then the total area needed is two times 400ft^2, or:
2*400ft^2 = 800ft^2
If we subtract this to the total area, we get:
4000ft^2 - 800ft^2 = 3200 ft^2
That is the square feet left for the development of other nonbathroom areas.

John leaves to go home. He walks 6 blocks north and the 8 blocks west.how far is John from the school?
Answer:
The answer is 10 blocks.
Step-by-step explanation:
The answer is confusing but you would really ask your self what 5*2 would be because if you were to use blocks you would calculate the length of the route but not the direct distance of home to school.
Enter the value for x that makes the equation true.
Answer:
Step-by-step explanation:
⅔(x-6) = ¾(x+16)
Multiply both sides by 12
8(x-6) = 9(x+16)
8x - 48 = 9x + 144
x = -192

Amy bought some shirts and skirts for $168. Each shirt cost $17, and each skirt cost $22. She
bought a total of 9 items. How many shirts did Amy buy
Answer:
3 shirts and 6 skirts
Step-by-step explanation:
lets call number of shirts x and number of skirts y
so x+y=9
17x+22y=168
multiplying the first equation by 17 we get
17x+17y=153
17x+22y=168
subtracting we get
5x= 15
x=3
and we know x+y=9 so y=6
so 3 shirts and 6 skirts
