Answer:

  Jhon

Step-by-step explanation:

At the rate of 4 minutes per problem, it take Juaqine ...

  (4 min/prob)×(6 prob) = 24 min

to solve the problems.

That is more time than it takes Jhon, so Jhon is faster.

The domain of startfraction f over g endfraction f g consists of numbers x for which g left parenthesis x right parenthesisg(x)
Misha Larkins [42]

The domain of f/g consists of numbers x for which g(x) cannot equal 0 that are in the domains of both f and g.

 

Let’s take this equation as an example:

If f(x) = 3x - 5 and g(x) = square root of x-5, what is the domain of (f/g)x. 


For x to be in the domain of (f/g)(x), it must be in the domain of f and in the domain of g since (f/g)(x) = f(x)/g(x). We also need to ensure that g(x) is not zero since f(x) is divided by g(x). Therefore, there are 3 conditions.

 

x must be in the domain of f: f(x) = 3x -5 are in the domain of x and all real numbers x.

x must be in the domain of g: g(x) = √(x - 5) so x - 5 ≥ 0 so x ≥ 5.

g(x) can not be 0: g(x) = √(x - 5) and √(x - 5) = 0 gives x = 5 so x ≠ 5.

 

Hence to x x ≥ 5 and x ≠ 5 so the domain of (f/g)(x) is all x satisfying x > 5.

 

Thus, satisfying <span>satisfy all three conditions, x x ≥ 5 and x ≠ 5 so the domain of (f/g)(x) is all x satisfying x > 5.</span>

PLEASSSSSEEE HELP A GIRL OUT PLZZ​

Answer:

B. The two lines are neither parallel nor perpendicular.

Step-by-step explanation:

First, put both lines into the same format. In this example, we're going to use y=mx+b format.

x - 4y = -9

-4y = -x + -9

y = (-x + -9) / -4

y = (x+9)/-4

y = (-1/4)x + (-9/4)

y = 3x - 7

If two lines are parallel, they have the same slope. (ie 4 and 4)

If two lines are perpendicular, one line's slope is the negative reciprocal of the other. (ie 4 and -1/4)

Neither is true here.
