Answer:

y = x - 11

Step-by-step explanation:

First, turn the f(x) into a y:

y = x + 2 + 9

Now, switch the x and y.

x = y + 2 + 9

Add like terms.

2 + 9 = 11

x = y + 11

Now, solve for y. Subtract 11 on both sides.

y = x - 11

Selena walks from home to school each morning and back home each afternoon.altogether , she walks 2/3 mile each day . How far do

Ivanshal [37]

One days trip of to school from home and back home from school is 2/3 of a mile. We want to know how far it is to school from her house.

To solve this, we simply need to take half of the total distance (2/3)

$\frac{2}{3} / 2$

Next, we need to turn the 2 into a fraction. Every whole number can be made into a fraction by putting it over 1.

$\frac{2}{3} / \frac{2}{1}$

Because we are dividing, we need to invert the second fraction and then multiply.

$\frac{2}{3} * \frac {1}{2}$

Next, we multiply the top of the first fraction by the top of the second and the bottom of the first fraction by the bottom of the second.

$\frac{2}{6}$

Once you reduce, you get:

$\frac{1}{3}$

How do I solve this

Flauer [41]

Volume of Cylinder V₁ =πR². H

Volume of a cone V₂ = (1/3).πR².h

We know that H=4h (given) & R, the radius =75 &The total Volume = V₁+V₂,
We also know that the hopper has one cylinder & 2 equal cones
Hence
πR². H + 2 [(1/3).πR².h] =343,000 ft³
π(75)².H + 2[(1/3).π(75)².h] =343,000
But H = 4h, then
π(75)².4h + 2[(1/3).π(75)².h] =343,000. Solve for h
26250.π.h = 81,466.8.h = 343,000

& h=343,000/81,466.8, ==> h=4.16 ft & H =16.6 FT

If a line has a slope of -2/5 and a y-intercept of 9,<br> what is the equation

Tema [17]

Answer:

y = -2/5x + 9

Step-by-step explanation:

The slope will always be before the x. And intercept will always go after the slope. If your intercept is negative, remember to write it as x-9 rather than x+9.

And you'll always want to add the y = at the beginning
