Answer:

The value of the equation for y is y=\frac{a}{9-3x}.

Step-by-step explanation:

Consider the provided equation.

a=9y-3yx  

We need to solve the equation for y.

Take common y from right side.

a=y(9-3x)  

Divide both the sides by 9-3x.

\frac{a}{9-3x}=\frac{y(9-3x)}{9-3x}  

y=\frac{a}{9-3x}  

Hence, the value of the equation for y is y=\frac{a}{9-3x}.

Pls help
KATRIN_1 [288]

Answer:

169.04 in² (nearest hundredth)

Step-by-step explanation:

Surface area of a cone = \pir² + \pirl

(where r = radius of the base and l = slant height)

Given slant height l = 10 and surface area = 188.5

Surface area  = \pir² + \pirl

188.5 = \pir² + 10\pir

\pir² + 10\pir - 188.5 = 0

r = \frac{-10\pi +\sqrt{(10\pi )^2-(4\times\pi \times-188.5)} }{2\pi } = 4.219621117...

Volume of a cone = (1/3)\pir²h

(where r = radius of the base and h = height)

We need to find an expression for h in terms of l using Pythagoras' Theorem a² + b² = c², where a = radius, b = height and c = slant height

r² + h² = l²

h² = l² - r²

h = √(l² - r²)

Therefore, substituting found expression for h:

volume of a cone = (1/3)\pir²√(l² - r²)

Given slant height l = 10 and r = 4.219621117...

volume = 169.0431969... = 169.04 in² (nearest hundredth)

I'm confused- how do I form the equation with 2 pts?
klio [65]

Answer:

the equation of the line is   y = -3x - 6

Step-by-step explanation:

Note that since (0, -6) is the y-intercept, we can write the slope-intercept equation of the line as y = mx - 6.  The other given point is (-2, 0) (which happens to be the x-intercept also).  Starting with y = mx - 6, replace y with 0 and x with -2:  

0 = m(-2) - 6.  We now solve this for the slope, m:  0 = -2m - 6 becomes

2m = -6, or m = -3.

With m = -3 and b = -6, the equation of the line is   y = -3x - 6

what is the equation subtracting 7 from the product of 4 and a number results in the number added to 29
vitfil [10]

That would be:-

4x - 7 = x + 29

the solution:-

3x = 29 + 7

3x = 36

x = 12
