Answer: C

Step-by-step explanation:

The equation is 3x = 6, that represents 3 x ? = 6, babe. 3 x 2 = 6, so that means C must be the answer. If it was D, it would be 0.2 I think, and if it was B, it would’ve been -2. If it was A, it would’ve been 0. Bye-bye toots~

In a right triangle, the acute angles measure x + 15 and 2x degrees. What is the measure of the smallest angle of the triangle?

Nat2105 [25]

The sum of the three angles of a triangle is always 180 degrees. If the triangle is right, which means one of the angles measures 90 degrees, the other two angles should add up to 90 degrees. With this condition and the given above, x + 15 + 2x = 90. Solving for x in the equation gives x = 25. Substituting x to the given expression for the acute angles gives the measurements of 40 and 50 degrees. Thus, the smallest angle of the triangle is <em>40 degrees</em>.

What are the x and y intercepts of f(x) = x2-x-12/x2+5x+6 and is there a hole?

stiv31 [10]

Answer:

There are no holes. The VAs are x=4 & x=-4 the HA is x=2 the x intercepts are (-3,0) & (3,0) and the y intercept is (0,9/8).

Step-by-step explanation:

Given f ( x ) =2 x ^2 − 18/x^2-16

find all asymptotes, holes and intercepts.

Factor the numerator and denominator.

f ( x ) =2 ( x ^2 − 9 )/( x + 4 ) ( x − 4 )

f ( x ) =2 ( x +3 ) ( x − 3 )/( x + 4 ) ( x − 4 )

A hole exists when the numerator and denominator contain the same factor (a factor "cancels out"). This function has no holes.

To find the vertical asymptote(s) (VA), find the values of x

which make the denominator equal zero. The function is undefined at these values of x

because you cannot divide by zero.

Set each factor of the denominator equal to zero and solve.

x + 4 = 0 and x − 4 = 0

x = − 4 and x = 4

These are the VAs.

To find the horizontal asymptote(HA), compare the degree of the numerator and denominator. If the degrees are the same, the HA is the ratio of the leading coefficients.

For f ( x) =2 x ^2 − 18/x^2-16

the degree in both numerator and denominator is 2

and the ratio of the leading coefficients is 2/1=1

The HA is x = 2

The x intercept is the value at which the function (or "y") equals zero. If the numerator is zero, the function equals zero.

2 ( x + 3 ) ( x − 3 ) = 0

x + 3 = 0 x − 3 = 0

x = − 3 and x = − 3

The x intercepts are ( − 3 , 0 ) and ( 3 , 0 ) .

The y intercepts are found by setting x = 0 .

f ( 0 ) = 2 ( 0 ) ^2 − 18/( 0 )^2 − 16 = 9 /8

The y intercept is ( 0 , 9/ 8 ) .

The function h(x) has an x-intercept of 2 and a y-intercept of 8. what is the slope of h(x)

Mekhanik [1.2K]

Answer:

-4

Step-by-step explanation:

The slope of a function f(x) passing through two points of coordinates $(x_1,y_1)$ and $(x_2,y_2)$ is given by

$m=\frac{y_2-y_1}{x_2-x_1}$

Therefore, in order to find the slope of the function h(x) of this problem, we have to find the coordinates of 2 points.

We know that h(x) has an x-intercept of 2: the x-intercept is the point where the function crosses the x-axis, so the coordinates of this point are

$(2,0)$

Because at x = 2, the value of y is zero.

We also know that h(x) has an y-intercept of 8: the y-intercept is the point where the function crosses the y-axis, so the coordinates of this point are

$(0,8)$
