Find the inverse of the following function.

Margarita [4]

Let f(x) be y.

y = x³ + 3

Switch x and y:

x = y³ + 3

Now you need to isolate y and you would get inverse function.

x - 3 = y³

∛(x-3) = y

Final answer: f ⁻¹(x) = ∛(x-3)

Hope this helps.

Given the equation,D=m/v if D=6/7 and =m+3 then m=.

mamaluj [8]

Answer:

$m=18$

Step-by-step explanation:

The equation given is $D=\frac{m}{v}$

and also we have that $D=\frac{6}{7}$ , thus:

$\frac{6}{7}=\frac{m}{v}$

------------

I think the question is missing which variable is defined as $=m+3$ , so I will solve for $v=m+3$ since is the only other variable in the equation.

substituting $v=m+3$ into $\frac{6}{7}=\frac{m}{v}$ :

$\frac{6}{7}=\frac{m}{m+3}$

and we solve for m:

$(m+3)(6)=7m\\6m+18=7m\\18=7m-6m\\18=m$

m is equal to 18.

15% of the students in school eat hot lunch. If 60

morpeh [17]

Answer:

400 students

Step-by-step explanation:

So 15 percent is 60 students

make an equation

0.15x=60

X stands for the total amount fo students and multiply that 0.15 becuase we know ti equals 60 and finding X will solve both problems

that’ll give you 400 students

if you check

400*0.15=60

So its correct

2 x - 5 + 7 y - 3 = 9 x - 1 - y -8 Solve For X AND Y (SHOW WORK PLEASE)

Maru [420]

Answer:

$\large\boxed{\sf x = \frac{8y+1}{7} }$

$\large\boxed{\sf x = \frac{7x-1}{8} }$

Group the Variable's:

2 x - 5 + 7 y - 3 = 9 x - 1 - y -8

2x -9x + 7y +y = -1 -8 +5 + 3

-7x + 8y = -1

From this find x and y

For X

-7x + 8y = -1

-7x = -1 -8y

7x = 8y + 1

x = (8y +1)/7

For Y

-7x + 8y = -1

8y = -1 +7x

y = (7x -1)/8
