Answer:

Step-by-step explanation:

B is correct. At x = 1 and past that, the graph is y = -x + 2. Notice the dark dot at (1, 1). The parabolic graph dominates from x = -infinity up to, but not including, (1, 3).

Whats the Fifth Root of 486 divided by the FIfth Root of 2

Gennadij [26K]

Answer:

Step-by-step explanation:

Rewrite the division as a fraction.

Combine into a single radical.

Simplify the expression.

Divide 486 by 2

Rewrite 243 as 3 ^5

Pull terms out from under the radical, assuming real numbers.

Hat function is represented by a line with slope −2 that passes through the point (0, 4)?

Gre4nikov [31]

Answer:

Step-by-step explanation:

You can use the formula y=mx+b

f(x) is the same as y

m=slope

b=y intercept

We know that the slope is -2 so which answer has -2 as b? (Which one has a -2 before the x?)

Y Intercept is where the line crosses though the y axis. The point of the y intercept will ALWAYS have 0 as x. So (0,4) is the y intercept. You could also say 4 is the y intercept. Which one has 4 as b? (Which one says +4 after -2x)

The only answer that matches is C.

I hope thay made sense.

The ratio of three numbers is 4 : 5 : 3. The sum of the numbers is 54. List the numbers in ratio form.

klemol [59]

let it be x.

4x + 5x + 3x = 54

12x = 54

x = 54/12

x = 4.5

Now 4x = 4× 4.5

= 18

3x = 3 × 4.5

=13.5

5x = 5× 4.5 = 22.5

Write a rational inequality with the solution: (-2,-1)U(1, oo)

serg [7]

Answer:

$\displaystyle \frac{x^2+3x+2}{1-x}$

Step-by-step explanation:

<u>Rational Inequality</u>

We are given the solution of rational inequality:

(-2,-1) U (1,∞)

The first set suggests a limited zone than can be obtained by a quadratic equation of the form:

$(x-a)(x-b)$

Where a and b are the roots of the equation, which coincide with the endpoints of the interval. Thus, to get the interval, we can use:

$(x+2)(x+1)$

Operating:

$x^2+3x+2$

The second set is an open infinite interval, that can be modeled as a third binomial that changes signs in x=1 and is in the denominator, so x=1 is not included.

Thus, one possible inequality is:

$\mathbf{\displaystyle \frac{x^2+3x+2}{1-x}$
