An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

Given function is

f(x)=7/3x -9

where x=-3.

Subtract x=-3 in the above function.

f(-3)=7/3(-3) - 9

f(-3)=7/-9 - 9

f(-3)=-7/9-9

f(-3)=(-7-81)/9

f(-3)=-88/9

Therefore f(-3) is -88/9.

The value of the arcsin of 3 is 90 - 100.998i

From the question, we are to determine the inverse sine or arcsine of the given number

The given number is 3

All the values for the sine of angles are less than or equal to 1

That is,

Given an angle θ,

sinθ ≤ 1

From this, we can infer that the arcsine of 3 will be an imaginary number.

The arcsine of 3 is

sin⁻¹(3) = 90 - 100.998i

Hence, the value of the arcsin of 3 is 90 - 100.998i

When Angelo drove home from college with an average speed of 71.7 mph and back to college with an average speed of 64.1 mph, she took 5 hours for full trip then the time taken to travel from home to college is 2.63 hours

Given,

The average speed from college to home = 71.7 mph

The average speed from home to college = 64.1 mph

We know,

Speed =  Distance / Time

Consider the total distance as x

Time taken = Distance / Speed

Then the time taken to travel from college to home  = [tex]\frac{x}{71.7}[/tex] hours

time taken to travel from home to college = [tex]\frac{x}{64.1}[/tex] hours

Total time taken = 5 hours

Then the equation will become

[tex]\frac{x}{71.7}+\frac{x}{64.1}=5[/tex]

Cross multiply the terms

[tex]\frac{64.1x+71.7x}{(71.7)(64.1)}=5\\ \frac{135.8x}{4595.97}=5[/tex]

135.8x= 5×4595.97

135.8x=22979.85

If the coordinate points is translated by the vector (2, -7), hence the resulting coordinate points will be:

A' = (2+2, 3-7) = (4, -4)

B' = (-2+2, 5-7) = (0, -2)

√x+7 The solution to the equation is x=-3.

Square root: If we take the square root of a number and then take the square of the outcome, we get the original number back again.

   e.g.  4 = 2 and 22 = 4.

We can say that the square root and the square cancel each other out. They are the inverse of each other.

If we have a number written with the index 2 ( squared) then taking the square root simply means that we leave out the 2 ( this only applies to positive numbers ).

We can therefore take any squared numbers that are under the square root sign out from under the root sign by leaving out the power 2.

The solution to the equation√x+7= -2.

√x+7= -2

First we take Squaring on both sides

(√x+7)2= (-2)2
