Mathematics

n200080 [17]3 years ago

Answer:

30

Step-by-step explanation:

y/x = 30/(x + 10)

(y + 12)/x = 54/(x + 10)

y/x + 12/x = 54/(x + 10)

30/(x + 10) + 12/x = 54/(x + 10)

30x + 12(x + 10) = 54x

30x + 12x + 120 = 54x

120 = 12x

x = 10

EG = x + x + 10

EG = 10 + 10 + 10

EG = 30

The graph of the function f(x) = (x - 3)(x + 1) is shown.
pychu [463]

Answer:

Step-by-step explanation:

Option A. All the real values of x where x < -1

Procedure

Solve the inequality:

(x -3)(x+1)>0

That happens in two cases.

1) When both factors >0

x-3>0 and x+1>0

x>3 and x >-1

The intersection is x >3

2) When both factors <0

x-3<0 and x+1<0

x<3 and x<-1

the intersection is x<-1.

We have obtained that the function is positive for the intervals  x < -1 and x > 3. But in one of those intervals the function is decresing and in the other is increasing.

You can recognize that the function given is a parabola and, because the coefficient of the quadratic term is positive, the parabola opens upward. Then the function is decreasing in the  first interval and increasing in the second interval.

Answer:

g(x) has a greater y intercept than f(x)

Step-by-step explanation:

f(x) = 6x^2 + 18x +3

f(0) = 0+0+3

The y intercept is 3

g(x) crosses the y axis at 6

The y intercept is 6

g(x) has a greater y intercept than f(x)
