Answer:

Option B. 3/4 > 2/3 is the correct answer.

Step-by-step explanation:

Lets look at the options one by one

A. 1/2 < 1/3

This inequality converts into 0.5<0.33 which is false.

B. 3/4 > 2/3

This simplifies to 0.75>0.666 which is true.

C. -1/4 < - 2/3

This converts to -0.25<-0.666 which makes the inequality false.

D. -1 > 3/4

This converts to -1>0.75 which makes the inequality false.

Hence,

Option B. 3/4 > 2/3 is the correct answer.

Identify a reflection about the x-axis or a reflection about the y-axis of f(x) = √-x by observing the equation of the function

olga55 [171]

Answer:

B) The base graph has been reflected about the y-axis

Step-by-step explanation:

We are given the function, $f(x)=\sqrt{-x}$ .

Now, as we know,

The new function after transformation is $g(x)=f(-x)=\sqrt{x}$ .

<em>As, the function f(x) is changing to g(x) = f(-x)</em> and from the graph below, we see that,

The base function is reflected across y-axis.

Hence, option B is correct.

Answer: y = - 0.4 x - 4.5

Step-by-step explanation:

Equation y=mx+b

m is the slope

x is *ANY* x coordinate

y is *ANY* y coordinate

b is y intercept or WHERE the point is on the Y AXIS

Lets look at the given:

Slope (m) is -2/5

Passes through point 15, -9/2

As you can see, the point goes through the Y axis at (-9/2)

Our equation is y = - 0.4 x - 4.5

Find the distance between the two points (-2,-6) and (0,5).

HACTEHA [7]

Answer: OPTION B

Step-by-step explanation:

You can find the distance between two points by using the following formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Given the points (-2,-6) and (0,5), you can identify that:

$x_2=-2\\x_1=0\\\\y_2=-6\\y_1=5$

Therefore, substituting values, you get that the distance between those points is:

$d=\sqrt{(-2-0)^2+(-6-5)^2}\\\\d=5\sqrt{5}$
