Answer:

D)   f (-1) (x) = x³-12

Step-by-step explanation:

∛x+12                      

Interchange the variables and solve for y

∛y +12 =x

(∛x+12) ³= x³

y+12 = x³

y= x³-12

f (-1) (x) = x³-12

.Write a division equation so that it has a solution of -2
Irina18 [472]
Let’s take a random number such as 10, for example as the divisor of the equation.
Let’s take the dividend, or numerator of the fraction be x.
The solution of the fraction would be -2.

x/10 = -2
Or, x= -2 x 10
Or, x= -20

Therefore, -20/10 = -2
Ans: The division equation would be -20/10 = -2.

The scale of a map is 6 km = 4 mi. What is the length on the map if the actual is 40.1<br> miles.
beks73 [17]

Answer:

60.15 km

Step-by-step explanation:

If 6 km on the map represents 4 mi on land, then we'd get the answer by using the relation

6 km -> 4 mi

x km -> 40.1 mi

Where x km is the length on the map we're looking for. If we cross multiply

6 * 40.1 = 4x

240.6 = 4x

x = 240.6/4

x = 60.15 km.

That is the length we're looking for

.Solve the system of equations. Use elimination
Elina [12.6K]

Answer:

a) (-9,3)

Step-by-step explanation:

   x + 2y = -3

- (x -    y = -12)

<u />

x + 2y = -3

<u>- x + y =  12</u>

       3y =  9

          y = 3

x - y = -12

x- 3 = -12

x= - 9

(-9, 3)

How to find all possible functions with the given derivative ? If
Gre4nikov [31]

Answer:

a) y = -\frac{1}{7}\cdot \cos 7\cdot t + C, b) y = -\frac{1}{7}\cdot \cos 7\cdot t + 7\cdot \sin \left(\frac{t}{7}\right) + C.

Step-by-step explanation:

a) The antiderivative of y' = \sin 7\cdot t is:

y = -\frac{1}{7}\cdot \cos 7\cdot t + C

b) The antiderivative of y' = \sin 7\cdot t + \cos \left(\frac{t}{7}\right) is:

y = -\frac{1}{7}\cdot \cos 7\cdot t + 7\cdot \sin \left(\frac{t}{7}\right) + C
